Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an aqueous hair styling composition that can be suitably used as a gel or aerosol foam hair styling composition.

[Conventional technology and problems to be solved by the invention] Looking back at the history of men's hair styling products, pomade and tick-type hair styling products have become mainstream, and recently gel-type and foam-type hair styling products have become mainstream. has come to be preferred. Looking at the finish, there has been a shift from oil-based types with a strong stickiness to water-soluble types with less stickiness.

Furthermore, conventionally, a method of solubilizing a relatively hydrophobic hair styling agent in an ethanol solvent has been mainly adopted as a method for preparing a hair styling agent. However, as mentioned above, in recent years, gel-like and foam-like water-based hair styling products with less stickiness have become mainstream, and it is extremely difficult to solubilize hydrophobic hair styling bases in such systems. Most of the hair styling bases used are water-soluble.

On the other hand, the older generation, who are accustomed to the finish of pomades and hair liquids, have a strong oily feel.

A hair styling agent having sufficient hair styling power and hair holding power is preferred,
Furthermore, even for young people with hair styles such as Regent, hair styling products with a strong oily finish are effective.

For this reason, recently many products called "wet J type" have been proposed, which use large amounts of polyhydric alcohol and have a finish that is relatively similar to that of pomades and hair liquids. It has been difficult to obtain an oily finish, strong hair styling ability, and hair holding ability that will satisfy generations.

The present invention was made in view of the above circumstances, and an object of the present invention is to provide an aqueous hair styling composition that has both a less sticky finish, a highly oily finish, and hair styling and hair holding power.

[Means and effects for solving the problem] As a result of extensive studies to achieve the above object, the present inventor has found that when polyoxypropylene diglyceryl ether and polyoxypropylene sugar ether are used together, gel-like or In a system containing a large amount of water in the form of a foam, both components act synergistically to provide a non-sticky finish, as well as a strong oily finish with excellent hair styling and hair holding power, making it suitable for use with pomades and hair liquids. Water-based that can fully satisfy even the older generation who are accustomed to the finish! ! It was discovered that a hair composition can be obtained, and the present invention was completed.

In addition, according to the inventor's study, the two essential components mentioned above are polyoxyethylene derivatives, and even if both components are used together, the hydrophilicity is too strong and the oily feeling and hair styling ability are insufficient, and the alkylene group However, when used in combination with a polyoxyalkylene derivative having a butylene group or more, it becomes hydrophobic and difficult to dissolve in water, and is highly sticky.However, surprisingly, by using polyoxypropylene derivatives as both components and using these two components together. The above-mentioned excellent performance is exhibited.

Therefore, the present invention provides an aqueous hair styling composition characterized by containing polyoxypropylene diglyceryl ether and polyoxypropylene sugar ether.

The present invention will be explained in more detail below.

The polyoxypropylene adduct of diglycerin, which is the first essential component of the aqueous hair styling composition of the present invention, can be obtained by adding propylene oxide to a dimer of glycerin, and the number of moles added is 3-50. Particularly preferred are those of 5 to 30. If the number of moles added is less than 3, an oily feel may not be developed, and if it exceeds 50, hydrophobicity may increase and it may become difficult to dissolve in water.

Such a polyoxypropylene adduct of diglycerin can be easily obtained by addition-polymerizing diglycerin with propylene oxide as described in JP-A-53-15435. Specifically, a product obtained by adding 9 moles of oxypropylene to diglycerin (ST-DP9) sold by Hanhon Yakuhin is exemplified.

Further, the blending amount of the polyoxypropylene adduct of diglycerin is preferably 0.1 to 50% (weight %, same hereinafter), particularly 1 to 30% of the total composition. If the amount is less than 0.1%, the oily feel may not be exhibited and the desired effect may not be obtained, and if it exceeds 50%, the hair may become sticky and have an undesirable heavy finish. be.

Next, the second essential component of the present invention is polyoxypropylene sugar ether.

In this case, polyoxypropylene sugar ether can be obtained by adding propylene oxide to saccharides such as sorbitol and mannitol, and the saccharides are not particularly limited, but sorbitol is one of them. suitable. In addition, polyoxypropylene sorbitol is disclosed in Japanese Patent Application Laid-Open No. 5Q-12684.
It can be easily obtained by addition polymerizing sorbitol with propylene oxide as described in Japanese Patent No. 1.

In the above polyoxypropylene sugar ether, the number of moles of propylene oxide added is 3 to 50, preferably 5.
~30. The number of moles of propylene oxide added is 3
If it is less than 50, the hydrophilicity is too strong and it is easily soluble in water, but the hair styling ability is weak, and if it exceeds 50, the hydrophobicity increases and it becomes difficult to solubilize in water. Furthermore, the finish may have a sticky feel. The blending amount of the above components is 1 to 50%, preferably 5 to 30%, based on the entire composition.
%. If the amount is less than 1%, sufficient hair styling power cannot be obtained, and if it exceeds 50%, the finish may feel sticky.

The present invention is applied to systems containing water, and is particularly effective in systems in which water accounts for 30% or more of the total composition.

In addition, the composition of the present invention is effective for gel-like or aerosol-type foam powder products, and in this case, for example, in gel-like products, a water-soluble polymeric substance such as carboxyvinyl polymer may be used as a thickener. This is common, and a large amount of water is required in the system for this water-soluble polymer substance to exhibit a thickening effect.

On the other hand, aerosol-type foam products usually use surfactants such as stearyltrimethylammonium chloride or polyoxyethylene hydrogenated castor oil as blowing agents, but a large amount of water is required to obtain good foam quality. is essential;
According to the present invention, it can be suitably used in such a system.

The following known components can be blended into the present invention within a range that does not affect the effects of the present invention.

For example, ultraviolet absorbers such as oxybenzone and its derivatives, ether surfactants such as polyoxyethylene (20) oleyl ether and polyoxyethylene (20) stearyl ether, and cationic interfaces such as stearyltrimethylammonium chloride and distearyldimethylammonium. Active agents, amphoteric surfactants, anionic surfactants, nonionic polymer compounds such as polyvinyl, rubirolidone/vinyl alcohol copolymers, anionic polymer compounds such as carboxyvinyl polymers, acrylic acid-based amphoteric polymers (
amphoteric polymer compounds such as (trade name: Yukahomer), oils such as polyether-modified silicones, lanolin derivatives, ρ-
Cooling agents such as menthol, stimulating agents such as benzyl nicotinate, sterilizing preservatives such as chlorhexidine gluconate, isopropylmethylphenol, paraoxybenzoate, protein hydrolysates, amino acids, plant extracts, vitamin A, Various vitamins such as B, C, D, E, and H, chelating agents such as EDT A-N a, pHrA regulators such as amber 11/sodium citrate/triethanolamine, and liquefied petroleum for aerosol products. Examples include gases, propellants such as dimethyl ether, and the like.

As mentioned above, the hair styling composition of the present invention is used in an aqueous form as a hair styling product containing a large amount of water, such as a gel or foam, and water is used as a solvent. Then, a water-soluble organic solvent such as ethanol can be added (usually 1 to 30%).

〔Effect of the invention〕

As explained above, the aqueous hair styling composition of the present invention is less sticky to hair, has a highly oily finish, and has excellent hair styling and hair holding power.

Therefore, according to the present invention, it is possible to obtain a highly oily finish similar to that of pomades, hair liquids, etc. in a hair styling product composed of a large amount of water, such as a gel or foam. It is possible to reduce the stickiness of the hair during finishing, which is a drawback of hair styling products such as liquid.

Therefore, the aqueous hair styling composition of the present invention has a feeling of use that can be fully satisfied by the older generation who are accustomed to the finish feel of hair styling products such as pomades and hair liquids, and also has an oily feel such as regent. Hairstyles are also very beneficial for young people.
