Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a hair cosmetic. More specifically, the present invention relates to a low-grade alcohol medium oil type hair cosmetic composition which imparts excellent luster to hair and gives a smooth feel, and further has an excellent hair extending effect.

[0002]

2. Description of the Related Art Conventionally, in hair cosmetics, for the purpose of giving gloss and smoothness to hair and for the purpose of extending curly hair,
Oils such as silicone oil, ester oil, hydrocarbon oil,
Used after solubilization, emulsification or dissolution.

[0003] Among them, silicone oils, in particular, have a low surface tension, are excellent in conformity to hair, and have good luster, and have been widely used in recent years.

[0004]

However, there is a limitation that oil has a limit, and there is a disadvantage that hair is greasy when used in a large amount or when used by a user for a long time.

[0005] In addition, cationic surfactants are often used for the purpose of imparting smoothness to hair, but they do not give desirable gloss. When a large amount of cationic surfactant is added, safety is not preferred. There was a disadvantage.

[0006] Accordingly, there has been a demand for a hair cosmetic which can solve these problems and efficiently extend the curly hair, and gives the hair a gloss and a good feel.

The inventors of the present invention have conducted intensive studies in view of the above-mentioned problems, and as a result, when the organic silicone resin is emulsified using a specific polyether-modified silicone as the sole emulsifier, the above-mentioned problems can be solved and the curly hair can be efficiently removed. The present inventors have found that an emulsified hair cosmetic which can be extended, imparts gloss to hair, and imparts a good feel can be obtained, thereby completing the present invention.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below in detail.

The organosilicone resin used in the present invention comprises an appropriate combination of R ₃ SiO _1/2 unit, R ₂ SiO unit, RSiO _3/2 unit and SiO _1/2 unit, and the ratio is an average. Is represented by the general formula: R _n SiO
_{(4-n) / 2} (wherein, R represents a hydrocarbon group having 1 to 6 carbon atoms or a phenyl group, and n represents a value of 1.0 to 1.8).
It is a silicone resin selected to satisfy

The organosilicone resin forms a film on the hair when the emulsified hair cosmetic composition of the present invention is applied to hair. In the above general formula, when R has more than 6 carbon atoms, , The coating becomes too soft. Also,
When n is less than 1.0, the film lacks smoothness, and when it exceeds 1.8, the viscosity is too high, which is not preferable for blending hair cosmetics.

The weight average molecular weight of the organic silicone resin is desirably about 1500 to 10,000.

The amount of the organic silicone resin used in the present invention is 0.1 to 50.0% based on the total amount of the hair cosmetic.
% By weight, preferably 1.0 to 25.0% by weight.
If the amount is less than 0.1% by weight, the effect of the present invention cannot be sufficiently obtained, and if the amount exceeds 50.0% by weight, the effect of the present invention is not enhanced.

The polyether-modified silicone used as an emulsifier in the present invention is an organopolysiloxane having a polyoxyalkylene group represented by the above chemical formula (2). In the present invention, commercially available products (TS polymer 50-IP: manufactured by Toray Dow Corning Silicone Co., Ltd.) can be used. The first point of the present invention is that the above-mentioned organic silicone resin is emulsified by using a specific polyether-modified silicone represented by the above-mentioned chemical formula (2) as an emulsifier, and a lower alcohol having excellent emulsion stability. This is because a medium oil type emulsified hair cosmetic can be provided, and in the present invention, it is not necessary to use a conventional surfactant as an emulsifier.

At least one of the three A's of the above chemical formula "Chemical Formula 2" of the polyether-modified silicone has a general formula:
—C ₃ H ₆ O (C ₂ H ₄ O) _a (C ₃ H ₆ O) _b It must be a polyoxyalkylene group represented by R ′, and the polyether-modified silicone molecule contains 40 polyoxyalkylene groups. It must be contained at least by weight. The acyl group of R ′ in the polyoxyalkylene group is specifically,
Formyl group, acetyl group, propionyl group, butyroyl group, acryloyl group, benzoyl group, toluoyl group and the like are exemplified, and the alkyl group having 1 to 4 carbon atoms is specifically,
Examples thereof include a methyl group, an ethyl group, an i-propyl group, an n-propyl group, a t-butyl group, and an n-butyl group. In addition,
When a or b is less than 5 in the polyoxyalkylene group, the polyether-modified silicone does not show a sufficient emulsifying effect, and when a or b exceeds 50, the resulting emulsified hair cosmetic Feeling becomes sticky. Further, the content of the polyoxyalkylene group is 40% by weight or more, and preferably in the range of 40 to 70% by weight. When the content of the polyoxyalkylene group is less than 40% by weight, the emulsifiability of non-polar oils other than silicone oil decreases, and when the content exceeds 70% by weight, the obtained emulsified hair cosmetic composition becomes sticky. It is because it comes to have. M is an integer of 50 to 1000;
Preferably, it is an integer of 150 to 1000, and n is 1 to 4
It is an integer of 0. This means that m is less than 50 and n is 1
If it is less than 3, the emulsifying effect is insufficient and
If n exceeds 1,000 and n exceeds 40, the resulting emulsified hair cosmetic will have a sticky feeling. Further, m: n is preferably from 200: 1 to 5: 1, and particularly preferably from 60: 1 to 15: 1.

Further, a polyether-modified silicone in which all Rs of the above chemical formula (2) are methyl groups is preferred.

The molecular weight of the polyether-modified silicone is 3
0000 or more, preferably 50,000 to 8000
0 is preferred. If the molecular weight of the polyether-modified silicone is less than 30,000, the emulsifying function may be reduced.

The viscosity of the polyether-modified silicone is not particularly limited. However, in order to form a particularly stable emulsion and to obtain an emulsified hair cosmetic composition having a dry feeling, the polyether-modified silicone is preferably made of octamethyltetrasiloxane or isoparaffin. It is desirable that the viscosity of a 50% by weight solution of the above is in the range of 1,000 to 100,000 cps.

The amount of the polyether-modified silicone is not particularly limited, but is preferably 1 to 50% by weight, more preferably 3 to 30% by weight based on the total amount of the emulsified hair cosmetic.
%, More preferably 3 to 20% by weight. If the blending amount of the polyether-modified silicone is less than 1% by weight, stable emulsification is difficult, and if it exceeds 50% by weight, the emulsified hair cosmetic will have a sticky feeling.

In the present invention, the lower alcohol medium oil type emulsified hair cosmetic means that the continuous phase is a lower alcohol or a water-lower alcohol mixed liquid phase.

The type of lower alcohol used in the present invention is not particularly limited, but is preferably methanol or ethanol, and particularly preferably ethanol from the viewpoint of safety. In addition, i-propanol, n-propanol, t-butanol, s-butanol, etc. are too hydrophobic and are difficult to emulsify.

When the continuous phase is a water-lower alcohol mixture, the amount of the lower alcohol is preferably at least three times the weight of water relative to the amount of water. If the blending amount of the lower alcohol is less than 3 times the amount of water, the whole system may be gelled by the polyether-modified silicone, the viscosity may be too high, and emulsification may be difficult.

According to the conventional emulsification method, it has been difficult to obtain a stable low-alcohol medium-oil type emulsified composition at a high alcohol concentration. 30% by weight or more, especially 50% by weight
Even in the case of the above-mentioned high concentration, a stable emulsion composition can be obtained, and the importance of the present invention is understood.
