Abstract

PURPOSE:To provide the title cosmetic capable of giving the hair both smoothness and humectant feeling without causing hair dryness, containing a silicone oil and a polyoxyalkylene alkylglucoside. CONSTITUTION:Firstly, a silicone oil is formulated with a polyoxyalkylene alkylglucoside prepared by adding 1-30moles of 2C and/or 3C alkylene oxide(s) to an alkylglucoside with 1-4C straight chain or branched alkyl group bound to the oxygen at 1-site of glucose. Thence, the resulting formulation is further incorporated, where appropriate, with ingredients to be used in conventional hair cosmetics such as surfactants, polymeric compounds, oil components, alcohols, fragrances, and/or coloring matters, thus obtaining the objective cosmetic, The amounts of the silicone oil (e.g. methylpolysiloxane) and polyoxyalkylene alkylglucoside to be used are such as to be 0.01-20wt.% and 0.05-10wt.%, respectively. The present cosmetic can be prepared into hair rinses, hair treatments, hair blows, hair creams, etc.

Description

[Detailed description of the invention] [Industrial application field] The present invention is a hair rinse and hair treatment.

The present invention relates to hair cosmetics that can be applied as hair blowers, hair creams, etc., and more specifically, to hair cosmetics containing silicone oil that impart smoothness and moisturizing to the hair without making it frizzy.

[Prior Art and Problems to be Solved by the Invention] Conventionally, it has been proposed to add silicone oil to hair cosmetics to impart smoothness to hair and protect split ends. As silicone oils used for this purpose, methylpolysiloxane, methylphenylpolysiloxane, and polyether-modified polysiloxane are known.

However, although hair cosmetics containing these silicone oils impart good smoothness to the hair, the use of such silicone oil-containing hair cosmetics may cause the hair to feel loose or lose its moist feel. Therefore, improvements in this respect have been required.

[Means and effects for solving the problem] The present inventors,
In view of the above circumstances, a hair cosmetic that maintains good smoothness when using a silicone oil-containing hair cosmetic and does not have the disadvantages of causing a dry feeling or losing a moist feeling. As a result of extensive research, we found that silicone oils contain alkyl glucosides in which a linear or branched alkyl group with 1 to 4 carbon atoms is bonded to the oxygen atom at position 1 of glucose, and alkylene with 2 and/or 3 carbon atoms. When a polyoxyalkylene alkyl glucoside to which 1 to 30 moles of oxide is added is used in combination, a hair cosmetic having the excellent smoothness of a silicone oil, giving an excellent moisturizing feeling, and suppressing a dry feeling can be obtained. This discovery led to the present invention.

The present invention will be explained in more detail below.

The hair cosmetic according to the present invention is prepared and applied as a hair rinse, hair treatment, hair blow, hair cream, etc., and uses a combination of silicone oil and the polyoxyalkylene alkyl glucoside.

Here, as the silicone oil used in the present invention, any of those commonly used as acid components in hair cosmetics can be used, and examples include methylpolysiloxane, methylphenylpolysiloxane, amino-modified polysiloxane, Examples include betaine-modified polysiloxane, alcohol-modified polysiloxane, polyether-modified polysiloxane, fluorine-modified polysiloxane, epoxy-modified polysiloxane, mercapto-modified polysiloxane, carboxy-modified polysiloxane, and fatty acid-modified polysiloxane. In this case, among these, the viscosity at 25°C is 30c
Methylpolysiloxane of st or higher.

Alternatively, amino-modified polysiloxane is preferred.

These silicone oils can be used alone or in combination of two or more. The amount of this silicone oil to be blended depends on the usage form, application, etc. of the hair cosmetic, but can usually be 0.01 to 20% (weight %, the same applies hereinafter).

On the other hand, examples of the polyoxyalkylene alkyl glucosides used in the present invention include POE (10) methyl glucoside and POP (20) methyl glucoside.

POP(10)propyl glucoside, POE(10)P
Examples include OP(20) methyl glucoside, and one type of these can be used alone or two or more types can be used in combination. The blending amount of these polyoxyalkylene alkyl glucosides is preferably 0.05 to 10%, although it depends on the usage form and application of the hair cosmetic.

In addition to the above-mentioned components, the hair cosmetic composition of the present invention may contain the following optional components depending on the type of cosmetic composition, use, etc. Optional ingredients include cationic surfactants such as stearyltrimethylammonium chloride, distearyldimethylammonium chloride, and behenyltrimethylammonium chloride, nonionic surfactants such as polyoxyethylene derivatives, anionic surfactants, and amphoteric surfactants. agent, nonionic polymer compounds such as polyvinylpyrrolidone, vinylpyrrolidone-vinyl acetate copolymer, methacrylic acid ester copolymer (trade name: Yukaformer AM-75)
Amphoteric polymer compounds such as ether of hydroxycellulose and glycidyltrimethylammonium chloride (
Cationic polymer compounds such as product name: Leogard G),

Alcohol such as stearyl alcohol, petrolatum.

Oils such as isopropyl palmitate and persic oil, polyhydric alcohols such as propylene glycol, glycerin, and polyethylene glycol, hydrophilic oils such as polyoxypropylene polyoxyethylene butyl ether, other amino acids, vitamins, herbal medicines, ultraviolet absorbers, and antioxidants. agents, bactericidal preservatives, solvents, dyes, fragrances, etc.

〔Effect of the invention〕

The silicone oil-containing hair cosmetic of the present invention maintains the smoothness due to the silicone oil, suppresses the feeling of dryness, and has a good moist feeling.
