Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a foamy hair cosmetic, and more specifically, it has good applicability to the hair, excellent styling properties and cent retention properties, and can be used with a hair dryer after application. To provide an aerosol-type foamy hair cosmetic that provides a good moist and supple feeling when hair is styled using the above products, has a silky finish after styling, and does not have an oily feel.

[Conventional technology]

BACKGROUND ART In recent years, aerosol-type foam-like hair cosmetics have become popular for the purpose of improving dripping during application and ease of use, as well as increasing fashionability. However, in such foamy hair cosmetics, when the hair cosmetics are applied to the hair and dried while being styled, the resin contained in the hair cosmetics solidifies, making it difficult to pass through with a comb or brush. Dryness can make your hair dry and prone to damage. Furthermore, if the resin content of the foamy hair cosmetic is reduced or a moisturizing component is added to improve this problem, a problem arises in that the cent retention property deteriorates. In this way, conventional methods that rely on adjusting resin content and moisturizing ingredients satisfy all of the requirements for application, styling, and set retention, and also provide good moist and supple properties when dried while styling after application. It has been difficult to obtain a foamy hair cosmetic that provides a smooth finish and leaves hair smooth after styling.

[Problem that the invention seeks to solve]

The present invention has been made in view of the above problems, and
To provide a foamy hair cosmetic that is excellent in all of the application properties, styling properties, and cent retention properties for the hair, is moist and supple when drying, and has a soft and smooth finish.

[Means for solving problems]

As a result of repeated studies to solve the above-mentioned problems, the present invention combines a cationic polymer and an amphoteric polymer in a specific ratio, and achieves the effect of improving coating properties by adding a cationic polymer. Utilizes the effect of improving set retention by adding an amphoteric polymer, and further adjusts the feeling of use during styling and after finishing by adding a specific cyclic siloxane, and also adds a specific polydimethylsiloxane. This invention is based on the discovery that a foam-like hair cosmetic that can achieve the above objectives can be obtained by coexisting a polyoxyalkylene polymer and a propellant.

The gist of the present invention is that (a) the blending weight ratio of cationic polymer/ampholytic polymer is
5/3 to 10/3 0.05 to 0.5% by weight of a cyclic siloxane represented by the formula (b) [in the formula, ~Work 0; nba 1-10; P is 1-3;
R is 6-30; Y means a hydrogen atom or an acetoxyl group] 0.1-1.5% by weight of a polydimethylsiloxane-polyoxyalkylene polymer and (d) 2-20% by weight of a propellant. It is an object of the present invention to provide a foamy hair cosmetic characterized by containing the following.

[Details of the invention]

Hereinafter, the foamy hair cosmetic according to the present invention will be explained in more detail.

As a representative example of the cationic polymer to be blended into the foamy hair cosmetic of the present invention, for example, Gafquat
Copolymers of quaternized dialkylaminoalkyl acrylates such as JR (Union Carbide), or copolymers of quaternized dialkylaminoalkyl methacrylate and vinylpyrrolidone, such as JR (Union Carbide), etc. Ammonium group-containing cellulose ether derivatives or quaternized cellulose derivatives, such as Jaguar
Cationic polysaccharides such as gar, manufactured by MeyhalL, for example Luviquat.
Examples include quaternized vinyl pyrrolidone polymers such as (manufactured by Co., Ltd.), quaternized vinyl imidazole polymers, siliconized cationic polymers, and quaternized polyurethanes.

In addition, a typical example of an amphoteric polymer is a copolymer of a sulfonic acid (salt)-containing monomer and a tertiary nitrogen-containing monomer.
Those treated with a grading agent, such as propyl methacrylate sulfonate dimethylaminoethyl methacrylate-1 copolymer quaternized product, polymers or copolymers of monomers containing both quaternary ammonium groups and sulfone groups, For example 3
- Polymers or copolymers of dimethyl (methacryloylethyl) ammonium propane sulfonate, copolymers of carboxylic acid (salt)-containing monomers and tertiary nitrogen-containing monomers, such as vinylpyridine acrylic acid copolymers, carboxylic acid (salt)-containing monomers and tertiary nitrogen-containing monomers; A copolymer of a tertiary nitrogen-containing monomer and a tertiary nitrogen-containing monomer treated with a quaternizing agent, such as octylacrylamide acrylate/butylaminoethyl methacrylate/acrylic acid copolymer (National
(Sold under the name Amphomer by Starch). Polymers or copolymers of monomers containing both carboxyl groups and quaternized ammonium groups, such as N-methacryloylethyl N,N-dimethylammonium α
-N methylcarboxybetaine methacrylic acid alkyl ester polymer (sold by Mitsubishi Yuka Fine Co., Ltd. under the name Yukaformer AM75), and the like.

The blending ratio of the above cationic polymer and amphoteric polymer is 5/3 to 10.
/3. If this blending ratio is less than 5/3, that is, the blending ratio of the cationic polymer to the amphoteric polymer is small, the foamy hair cosmetic will have poor applicability to the hair, and the finish will be sticky, which is not desirable. When the ratio is 10/3 or more and the blending ratio of the beaten amphoteric polymer to the cationic polymer is small, the set retention becomes poor. Further, the total blending ratio of the cationic polymer and the amphoteric polymer to the entire foamy hair cosmetic is preferably 0.4 to 2.5 am%, and the blending ratio is 0.4% by weight. If it is less than 2.5 ffiffi%, a sufficient set retention effect cannot be expected, and if it is more than 2.5 ffiffi%, the amount of adhesion to the hair will be excessive, resulting in poor applicability or giving a strange feeling. Therefore, it is not desirable.

Next, the blending amount of cyclic siloxane is 0.05 to 0,
5% by weight is preferable, and if the blending amount is 0.05% by weight or less, the hair becomes dry when styling the hair after applying the foamy hair cosmetic to the hair, which is not preferable. If it exceeds Eii%, it is not preferable because the finish will be sticky and sufficient set retention will not be obtained.

Furthermore, the amount of the polydimethylsiloxane-polyoxyalkylene polymer blended is preferably 0.1 to 1.5% by weight, and if it is outside this range, the foamy hair cosmetic will be removed immediately when taken out from the aerosol container. It does not form into a foam and drips off the hands, making it difficult to use.

Further, the propellant used in the present invention is not particularly limited, and may be any commonly used propellant such as liquefied E oil gas, chlorofluorocarbon gas, dimethyl ether, etc., and these may be used alone or in combination of two or more. may be used together. The amount of the propellant to be blended is preferably 2 to 20% by weight, more preferably 4 to 15% by weight. Here, if the blending amount of the propellant is less than 2% by weight, it is not preferable because the volume of the foam will be extremely reduced or it will not become foamy when taken out from the aerosol container and used. If it exceeds this value, the texture of the foam will become rough, which is not desirable in terms of commercial value (foamy quality).

In addition to the above-mentioned ingredients, the foamy hair cosmetic according to the present invention may optionally contain plasticizers, oils, alcohols,
Surfactants, colorants, total blocking agents, thickeners, bubble stabilizers, ultraviolet absorbers, preservatives, Pl+ regulators, plant extracts, damaged hair repair agents, fragrances, and other additives are added to achieve the above performance. Of course, it can be added as appropriate within a range that does not impair the properties.
