Description

[Detailed description of the invention]

The present invention is applied to the skin surface to an appropriate thickness and dried over a certain period of time to soften the stratum corneum of the skin and provide appropriate tension to the skin, and after drying, temporarily raises the skin temperature and improves blood circulation. The present invention relates to a cosmetic, a so-called film-type pack agent, which can remove dirt on the skin and exhibit a cleaning effect when the formed film is peeled off. In more detail, it can be easily applied evenly, dries moderately in a short time,
A storage-stable product that is easy to peel off, forms a beautiful, uniform, and transparent film, and can be peeled off uniformly and easily without causing pain to the skin. It also provides a moist and moist feeling to the skin after peeling. This invention relates to a film type pack with good properties. Conventionally, film-type packs must meet the following requirements: (1) They must be highly safe without irritating the skin. (2) It should be able to be applied easily and uniformly, and form a homogeneous pack film by proper drying. (3) The peeling time of the formed pack film is short, the peeling is easy, and the peeling is uniform. (4) It should be able to give a moist and good feel to the skin from which the pack film has been removed. (5) Good storage stability (stable over time). (6) The pack film must be transparent and beautiful from the time it is applied until it is peeled off. However, there are almost no film-type packs on the market that can satisfy these conditions. In conventional commercially available packs that use polyvinyl alcohol as a film-forming agent, the adhesion of the polyvinyl alcohol film to the skin is too strong, making it difficult to peel off uniformly and causing pain to the skin when the film is pulled off. There are some easy drawbacks. Furthermore, this film-type pack agent has the disadvantage that it takes a long time to form a peelable film, and attempts have been made to improve this drawback by increasing the concentration of polyvinyl alcohol or adding metal powders. However, it has the disadvantage that it is difficult to apply evenly and lacks a moisturizing feel. Packs that use natural rubber or synthetic rubber latex generally have an uneven appearance (for example, spots).
It has disadvantages such as it tends to form a thick patch film, and when it is peeled off, the film stretches and breaks and hits the skin directly, causing strong pain. Japanese Patent Publication No. 36-550 describes nonionic surfactants such as fatty acid esters of polyhydric alcohols, polyoxyalkylene ethers of higher alcohols, sodium chondroitin sulfate, polyethylene glycol (#600) (average molecular weight 600), polyvinyl An oil-in-water emulsion film-type pack has been proposed, which is made by mixing and emulsifying a molten mixture of a nonionic active agent, an oily substance such as lanolin, silicone oil, or olive oil, and a fragrance in an aqueous solution containing alcohol. There is. However, this pack agent has insufficient emulsion stability and storage stability, and can be used under harsh conditions (45
℃) not only has the drawback of causing a separation phenomenon in a short period of time (one week), but also gives a strong feeling of tightness during film formation, and cannot impart a good moisturizing feeling to the skin after peeling. Furthermore, since this pack is an oil-in-water emulsion and has a milky white appearance, the applied face will have a white pack film, similar to the emulsion-type packs such as the aforementioned synthetic rubber latex and oil-based emulsions. Because it is covered with a white mask, it has the disadvantage of giving a strange feeling, as if it were wearing a white mask. In view of the current situation, the present inventors conducted extensive research and found that, as described below, when a specific water-soluble polyoxyalkylene methylpolysiloxane and polyethylene glycol are combined together, a nonionic surfactant is also used. discovered that it was possible to obtain an excellent film-type pack that solved all the drawbacks of the prior art and satisfied the above-mentioned requirements, and completed the present invention. The purpose of the present invention is to form a beautiful, transparent mask film that can be easily and uniformly applied, dries in a short time, and is easily and uniformly removed without causing any pain to the skin, while also maintaining the skin after the removal. To provide a film-type pack that can give a good firm feeling and has excellent storage stability. That is, the present invention has the general formula: (In the formula, R is an alkylene group having 1 to 5 carbon atoms,
R' is an alkylene group having 2 or 3 carbon atoms, R'' is a hydrogen atom or a methyl group, n is an integer from 0 to 15, and m is from 1 to
an integer of 50; a is an integer of 5 to 50; ), polyethylene glycol with an average molecular weight of 3,000 to 20,000, a nonionic surfactant and/or anionic surfactant, polyvinyl alcohol, and water are blended. , and the blending amount of the water-soluble polyoxyalkylene methyl polysiloxane is 0.3 to 10% by weight (weight%
is based on the total weight of prescription ingredients. Same below. ), the amount of polyethylene glycol in the first half is
It is a film-type pack agent with a concentration of 0.3 to 10% by weight. It is represented by the above general formula of the present invention. Water-soluble polyoxyalkylene methylpolysiloxane (hereinafter abbreviated as polyether-modified silicone) has a hydrophilic polyoxyalkylene group (alkylene ether group) or a side chain having a hydroxyl group in its molecule, so it is water-soluble. It not only has compatibility with lower monohydric alcohols and hydrophilic polyhydric alcohols (e.g. ethylene glycol, propylene glycol, glycerin, etc.), but also coexists in the system of the pack agent of the present invention. It also has high affinity with polyvinyl alcohol. Even from such chemical structure and characteristics, it is essentially different from silicone oil (an organic silicone compound that does not have a polyoxyalkylene group and is insoluble in water and soluble in oil). In addition, the polyether-modified silicone, like hydrophilic polyhydric alcohol, imparts an appropriate amount of moisture to the stratum corneum of the skin, exhibits good moisturizing and emollient effects on the skin, and also plasticizes the pack film. (softening), and the stiffness caused by the film can be moderately reduced and weakened. Moreover, when added in an appropriate amount, it shortens the time required to form a peelable film, improves peelability, and gives the skin a moist and good feeling after peeling. Significant. The aforementioned polyether-modified silicones represented by the above general formula can be used alone or in combination of two or more. The amount incorporated is usually 0.3 to 10% by weight, preferably 2 to 8% by weight based on the total weight of the prescription components. When the amount is less than 0.3% by weight, the time required to form a peelable film becomes longer, and the peelability deteriorates, making it impossible to peel uniformly. Furthermore, the feeling of tightness when the film is formed becomes strong, causing pain, and the moisturizing feeling when peeling off is insufficient, giving an undesirable dry feeling. When the amount exceeds 10% by weight, the time required to form a peelable film becomes longer, and the film formed on the skin becomes excessively soft, making uniform peeling difficult. Storage stability is also significantly reduced. The polyethylene glycol that can be used in the present invention has a larger average molecular weight than ordinary polyethylene glycol used as a wetting agent. The polyethylene glycol in the present invention has an average molecular weight of 3000 to 20000, preferably 4000.
~8000. When the average molecular weight is less than 3000, the time required to form a peelable film becomes longer.
Furthermore, the releasability becomes poor. When it is larger than 20,000, the formed film becomes brittle and cannot be peeled off uniformly. Such polyethylene glycols are used alone or in combination of two or more, and the amount used is 0.3 to 10.0%, preferably 1 to 7% by weight, based on the total weight of the prescription ingredients. If it is less than 0.3% by weight, the time required to form a peelable film becomes longer and it becomes difficult to peel the film uniformly.
When the amount exceeds 10% by weight, the pack film becomes brittle and cannot be peeled off uniformly, and storage stability deteriorates and it tends to aggregate. Preferred examples of the nonionic surfactant to be incorporated into the pack agent of the present invention include sorbitan fatty acid ester, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene fatty acid ester, polyoxyethylene alkyl ether, and polyoxyethylene alkyl allyl ether. . Preferred examples of the anionic surfactant include fatty acid soaps, higher alcohol sulfate sulfates, polyoxyethylene alkyl ether sulfates, polyoxyethylene alkyl ether phosphates and their salts. Usually, these surfactants are used alone or in combination of two or more. The amount of such surfactant used is 0.1 to 10% by weight, preferably 0.3 to 8.0% by weight, based on the total weight of the prescription components. When it is less than 0.1% by weight, the stabilizer content decreases, polyvinyl alcohol, etc. aggregate during long-term storage, and water syneresis occurs, resulting in non-uniformity. On the other hand, if the amount exceeds 10% by weight, the time required to form a peelable film becomes longer and the peelability of the film deteriorates, making it impossible to peel it off easily and uniformly. The blending amount of polyvinyl alcohol is 3 to 30% by weight, preferably 5 to 30% by weight based on the total weight of the prescription ingredients.
It is 25% by weight. When the amount is less than 3% by weight, storage stability tends to decrease, and a weak pack film tends to be formed, making it difficult to peel off. When the amount exceeds 30% by weight, it takes a long time to form a peelable pack film, and it tends to be difficult to apply it uniformly. The amount of water used is 35% based on the total weight of the prescription ingredients.
~90% by weight, preferably 50-85% by weight. Commonly used ingredients that can be incorporated into the pack of the present invention include perfumes, preservatives, dyes, cosmetic medicinal ingredients, and the like. In addition, if necessary, a PH regulator, alcohol, etc. can also be used within a range that does not inhibit the above-mentioned effects. The film-type pack agent of the present invention is in the form of a homogeneous liquid or paste, has excellent storage stability, and when used, spreads easily and can be applied uniformly.
It dries appropriately in a short period of time, forming a uniform and beautiful transparent pack film that is extremely easy to peel off.It peels off smoothly and uniformly without causing pain to the skin, and leaves a moisturizing effect on the skin after peeling. It is an excellent pack agent that can give a pleasant feeling, and its effects are remarkable. Examples of the present invention will be described below. In the examples, parts mean parts by weight, and % means weight %. The characteristics of the pack agent, such as the time required to form a peelable film (hereinafter referred to as peeling time) and peelability, were determined using the method shown below, and other characteristics were determined by practical tests (during application) by three specialized inspectors. stretch,
The ease of peeling, the feeling of tightness, the feeling of moisture), the appearance of the formed film, and the long-term storage safety were investigated. (1) Peeling time Apply 0.5 g of a sample of the film-type pack to a 3 cm x 3 cm area on the flexor side of the forearm to a uniform thickness, and wait until the pack forms a uniform film and The time required for uniform peeling was measured. When the peeling time was between 7 and 15 minutes, it was judged as good (easy to use), and when it was less than 7 minutes and over 15 minutes, it was judged as poor (difficult to use). (2) Peelability test (peel stress) Freeze-dried pork skin (Lyoderm) manufactured by BURN TREATMENT SKINBANK, which had been treated with purified water, was pasted on a 76 mm x 26 mm slide glass, and 1 g of the sample pack was applied to a uniform thickness on top of it. Apply it on the skin and leave it in a room at 35℃ and 75% humidity for 3 hours. Next, the film was left in a constant temperature chamber at room temperature and humidity of 75% for 1 hour, and the peel stress was measured using a rheometer at a peel rate of 0.6 mm/sec. When the peeling stress was less than 5 g, it was judged as good (easy to peel), when it was 5 to 10 g, it was judged as rather poor (slightly difficult to peel), and when it was 10 g or more, it was judged as poor (difficult to peel and felt pain). (3) Evaluation method for tingling sensation After applying a certain amount of the pack sample to the face,
During the process of forming a removable pack film, the strength of the feeling of tightness (tension) on the face caused by shrinkage of the film was evaluated on the following five scales. (Score), Expression of degree Details of tingling sensation (5 points), I feel it strongly...I feel severe pain. (4 points) I feel it very strongly...I feel pain and feel strange. (3 points), normal...I feel some pain and some discomfort. (2 points), rather weak...I hardly feel any pain or discomfort. (1 point), weak...I don't feel any pain or discomfort. Note that the score is the average score rounded off, and the expression corresponding to the score is shown as the result of the feeling of tightness. Example 1 After heating 65.9 parts of water to 85±5°C, 1.0 part of polyoxyethylene sorbitan monolaurate (20E.O) was added thereto, and further 15.0 parts of polyvinyl alcohol (average degree of polymerization 1600) was added. The mixture was gradually added while stirring, dispersed and dissolved for 45 minutes, and then cooled to room temperature. This solution will be referred to as Solution A. On the other hand, in 10.0 parts of water, polyether-modified silicone [in the general formula (1), n=0, m=40, a
=12, R= _-CH2 - _CH2- group, R'= _CH2 - _CH2-
5.0 parts of methyl paraoxybenzoate (preservative) and 3.0 parts of polyethylene glycol (average molecular weight 4000) were added and dissolved. This is referred to as Solution B. Next, as described above. While stirring, liquid B was gradually added to liquid A and mixed uniformly to obtain a colorless and transparent film type pack. When the peeling time of this pack was examined, it was found that it could be peeled off uniformly in 12 minutes. Next, when the peeling stress was examined by a peeling test, uniform peeling was possible at 2.1 g.
In addition, this pack agent spreads well when applied, can be applied easily and uniformly, forms a beautiful colorless and transparent pack film, has a weak feeling of tightness, and can be peeled off easily and uniformly without irritating the skin. was completed. Also, after peeling off, it gave a good moist feeling to the skin. Furthermore, when this pack was stored at 45°C for 6 months, the appearance was the same as that immediately after production, and no discoloration, separation, or aggregation was observed. As described above, the film-type pack agent of the present invention is extremely good, and is significantly superior to the pack agent according to the comparative example described below. Comparative Example 1 The same procedure as in Example 1 was carried out except that polyoxyethylene sorbitan monolaurate (20E.O) was not used and 76.9 parts of water was used. As a result, when the peeling time of the obtained film type pack was measured in the same manner as in Example 1, it was found that it could be peeled off uniformly in 13 minutes. Next, we examined the peeling stress and found that it could be peeled off uniformly at 3.5g. However, as in Example 1, 6
After being stored for several months, the entire product became cloudy, water was separated into the upper layer, and polyvinyl alcohol was partially agglomerated. Comparative Example 2 A sample was prepared in the same manner as in Example 1, except that carboxymethyl cellulose was used instead of polyvinyl alcohol. The resulting pack did not form a film. Comparative Example 3 The same procedure as in Example 1 was conducted except that the polyether-modified silicone used in Example 1 was not used and 80.9 parts of water was used instead. Example 1 The peeling time of the obtained film type pack was
When measured in the same manner as above, it took a long time of 37 minutes, and the peeling stress was as high as 17g, making it impossible to peel off uniformly.
Further, as a result of a practical test, it was found that the film had a tight feeling during formation and the adhesive force between the skin and the film was extremely strong, making it impossible to peel it off uniformly. Furthermore, the feeling after peeling off was insufficient in moisturizing feeling. Comparative Example 4 A sample was prepared in the same manner as in Example 1, except that polyethylene glycol (average molecular weight 4000) was not used and 78.9 parts of water was used. As a result, the peeling time of the resulting film-type pack was as long as 30 minutes, and the peeling stress was as high as 12 g, making it impossible to peel off uniformly. Comparative Example 5 A sample was prepared in the same manner as in Example 1, except that comparative polyethylene glycol (average molecular weight 600) was used instead of polyethylene glycol (average molecular weight 4000). The obtained film-type pack took a long time of 25 minutes, and the peeling stress was 13 g, making it impossible to peel off uniformly. When a practical test was conducted, it was found that the adhesion to the skin was extremely strong, and furthermore, the film formed on the skin was too soft to peel off uniformly. Example 2 After heating 63.7 parts of water to 85±5°C, 1.5 parts of polyoxyethylene oleyl ether (20E.O) was added, and further polyvinyl alcohol (average degree of polymerization

Solution C is prepared by sequentially dissolving 1.5 parts of polyoxyethylene hydrogenated castor oil (60E.O), 0.1 part of methyl paraoxybenzoate (preservative), and 0.1 part of triethanolamine in 5.0 parts. Next, Solution B was added to Solution A and mixed uniformly, and then Solution C was gradually added to the mixture and uniformly mixed and dispersed to obtain a colorless and transparent film-type pack. The peeling time of this pack was 11 minutes, and the peeling stress was 2.5 g.
In addition, it spreads well during application, making it easy to apply uniformly, forming a beautiful uniform colorless and transparent pack film. At that time, the feeling of tightness was weak, and it could be peeled off easily and uniformly without irritating the skin.
In addition, it gave a good moist feeling to the skin after peeling off. When this pack agent was stored at 45°C for 6 months, its appearance was the same as immediately after production, and no phenomena such as discoloration, separation, or aggregation were observed. Comparative Example 6 Instead of the polyether-modified silicone of the present invention used in Example 2, a polyether-modified silicone (water-soluble) represented by the following structural formula (comparative compound) was used.
Example 2 was carried out in the same manner as in Example 2, except that . As a result, the peeling time of the obtained film type pack was as long as 28 minutes, and the peeling stress was 6.8 g, meaning that it could not be peeled off uniformly. Comparative Example 7 The same procedure as in Example 2 was conducted except that dimethylpolysiloxane (silicone oil) was used instead of the polyether-modified silicone of the present invention used in Example 2. The obtained film type pack was cloudy, had a long peeling time of 27 minutes, and had a peeling stress of 7.9g.
(slightly large) and could not be peeled off uniformly. Also, the skin did not feel moisturized after peeling off, and it felt bad. Example 3 62.9 parts of water was heated to 85±5°C, and 1.0 parts of polyoxyethylene oleyl ether phosphoric acid (18E.O) was added to it.
13.0 parts of polyvinyl alcohol (average degree of polymerization 1400) was gradually added, dispersed and dissolved for 45 minutes, and cooled to room temperature. This solution will be referred to as Solution A. 10.0 parts of water, 3.0 parts of polyethylene glycol (average molecular weight 5000), polyether-modified silicone [n = 1, m = 40, a = 14 in the general formula (1),

The mixture to which 0.1 part was added is called Solution C. Next, Solution B was added to Solution A and mixed uniformly, and then Solution C was added and uniformly mixed and dissolved to obtain a colorless and transparent film-type pack. The peeling time of this pack is 12 minutes, and the peeling stress is
It weighed 2.6g and could be peeled off uniformly. This pack agent spread well when applied, and could be applied easily and uniformly. In addition, when the film was formed, a beautiful, colorless and transparent uniform pack film was formed, and the film was peeled off uniformly without giving any irritation to the film. After peeling off, it gave a good moist feeling to the skin. When this pack was stored at 45°C for 6 months, the appearance was the same as immediately after manufacture, with no discoloration, separation,
No phenomena such as aggregation were observed. Example 4 (Influence of blending amount of polyether-modified silicone) Prescription components include 3.0 parts of polyethylene glycol (average molecular weight 4000), 13 parts polyvinyl alcohol (average degree of polymerization 1600), and 1.0 parts polyoxyethylene cetyl ether (10E.O). part and 0.1 part of methyl paraoxybenzoate, polyether-modified silicone [However, in the general formula (1) above, n

Each film-type pack was produced in the same manner as in Example 1, except for the use of the following ingredients. Table 1 shows the properties of each pack agent obtained. As is clear from the results in Table 1, the blending amount of the polyether-modified silicone (represented by the general formula above) in the present invention is 0.3 to 10%, preferably 2.0 to 8.0%, based on the total amount of prescription components. It is. If the amount is less than 0.3%, the time required to form a peelable film will be longer, making it difficult to peel off the film uniformly, and the feeling after peeling will be poor (lack of moisturizing feel). Furthermore, if the amount exceeds 10%, the pack film formed on the skin becomes too soft and cannot be peeled off uniformly, resulting in a marked decrease in storage stability.

Each film type pack was produced in the same manner as in Example 1, except that 0.1 part of methyl paraoxybenzoate, 3.0 parts of polyethylene glycol having each average molecular weight shown in Table 2, and 77.4 parts of water were used. Table 2 shows the properties of each pack agent obtained.

【table】

[Table] As is clear from the results in Table 2, the average molecular weight of polyethylene glycol in the present invention is
3000-20000, preferably 4000-8000.
When it is less than 3000, the time required to form a peelable film becomes long, and it becomes difficult to peel the film uniformly. Moreover, when it is larger than 20,000, the pack film formed on the skin becomes brittle and cannot be peeled off uniformly, and storage stability deteriorates.

Each film was prepared in the same manner as in Example 1, except that 7.0 parts, 10.0 parts and 15 parts were used, and water was used in the corresponding amount (remaining amount) to make the total amount of each prescription component 100 parts. A mold pack was manufactured. Table 3 shows the characteristics of each pack agent obtained.

[Table] As is clear from the results in Table 3, the blending amount of polyethylene glycol in the present invention is 0.3 to 10.0%, preferably 0.3 to 10.0% based on the total amount of prescription ingredients.
It is 1.0-7.0%. When the amount is less than 0.3%, the time required to form a peelable film becomes longer and it becomes difficult to peel off the film uniformly. Furthermore, the moisturizing feeling after peeling off is insufficient. 10 again
%, the pack film that forms on the skin becomes brittle and cannot be peeled off evenly.
In addition, storage stability deteriorates and aggregation occurs. Comparative Example 8 3.0 parts of polyoxyethylene sorbitan monolaurate (20E.O), 1.0 parts of sodium chondroitin sulfate, 5.0 parts of polyethylene glycol (average molecular weight 600), and 10.0 parts of polyvinyl alcohol (average degree of polymerization 1700) were added to 73.9 parts of water. After adding sequentially, 70~
It was heated to 80°C to dissolve it. This is called liquid A. Meanwhile, 2.0 parts of sorbitan monostearate, 3.0 parts of lanolin, 2.0 parts of dimethylpolysiloxane (silicone oil), and methyl paraoxybenzoate
After adding 0.1 part and mixing, the mixture was heated and melted at 70 to 80°C. This molten mixture will be referred to as liquid B. Next, add B to liquid A.
The liquid was added while stirring, emulsified, and cooled to room temperature to obtain a cloudy film-type pack. The peeling time of this pack was as long as 35 minutes, and the peeling stress was as high as 14g, making it impossible to peel off uniformly. When we conducted a practical test, we found that the film had a strong feeling of tightness when it was formed, and the adhesion to the skin was extremely strong, making it impossible to peel it off uniformly. In addition, the feel was unfavorable, and it was not possible to give a moist feel to the skin after peeling. Furthermore, this pack agent significantly separated after one week at 45°C.

The peeling time of the obtained film-type pack was 13 minutes, and the peeling stress was It weighed 2.1g. Also, when applied, it spread well and was easily applied evenly, forming a colorless and transparent beautiful uniform patch film, and the gap between pecks was moderately weak. When peeling off, it did not irritate the skin. It peeled off evenly and gave the skin a good moist feeling after peeling off.
After being stored for several months, the appearance was the same as that immediately after production, and the stability was extremely good.
