Description

Detailed Description of the Invention 3. Detailed Description of the Invention The present invention relates to a hair cosmetic composition used as a setting lotion, hair spray, etc.

It is well known that in hair cosmetic compositions such as setting lotions, polymeric compounds such as polyvinylpyrrolidone, polyvinylpyrrolidone/vinyl acetate copolymers, and acrylic resins are used to impart setting properties. A technique for improving the set retention properties and hair texture of hair cosmetics containing such polymeric compounds is to blend acrylic resins with specific plasticizers such as Sollubit fatty acid ester ethylene oxide adducts (Japanese Patent Application Laid-Open No. (Sho 53-99338)
or using a specific polydimethylsiloxane/polyoxyalkylene block copolymer (Japanese Patent Laid-Open No. 49-41)
No. 547) and the like have been proposed.

However, these hair cosmetics still have insufficient set retention properties and hair texture.

An object of the present invention is to provide a hair cosmetic composition that has good set retention properties and can impart a good texture to hair.

The hair cosmetic composition of the present invention comprises the following (a) and (b):
) component.

(a) High molecular compound.

(b) Polysaccharide.

The present invention will be explained in more detail below.

(a) Component polymer compounds include cationic polymer compounds, anionic polymer compounds, amphoteric polymer compounds,
A nonionic polymer compound is used.

Specific examples of cationic polymer compounds include the following. Here, the corresponding name in parentheses indicates the name of a commercially available product.

1) Cationized cellulose such as ether of hydroxyethylcellulose and glycidyltrimethylammonium chloride (Leogard G Nilion ■, Polymer J
R-30M-125 and the same 400: manufactured by Union Carbide) 2) Quaternized vinylpyrrolidone/dimethylaminoethyl methacrylic acid copolymer (GAFQUAT734 and 755: manufactured by GAF), 3) Dimethyl diallylammonium chloride polymer ( MERQUAT 100: manufactured by Merck & Co.), 4)
Dimethyldiallylammonium chloride/acryloamide copolymer (MERQLIAT550: Merck II).

Specific examples of anionic polymer compounds include the following.

1) Ethyl acrylate/acrylic amide/acrylic acid copolymer (Ultrahold 8: manufactured by Ciba Kaigy)
, 2) Methyl vinyl ether/maleic anhydride copolymer (Gantretz AN-119, AN-139, AN
-169: Manufactured by GAF), 3) Methyl vinyl ether/maleic acid monoalkyl ester copolymer GANTRETS ES-225, ES
-425: manufactured by GAF), 4) Acrylic ester/methacrylic ester/acrylic acid copolymer or its neutralized product (Plasticize L-530, same L-53P: manufactured by Gauoi Kagaku ■, all of the above are neutralized) 5) Vinyl acetate/crotonic acid copolymer (Resin 28-1
310, 28-2930: Manufactured by National Starch Co.)
.

As the amphoteric polymer compound, an amphoteric compound of a methacrylic acid ester copolymer is used, and in particular, the following general formula (■)
The one represented by is suitable.

Examples of nonionic polymer compounds include the following.

l) Polyvinylpyrrolidone (PVP K-30, -60, -90: manufactured by GAF) 2) Vinylpyrrolidone/vinyl acetate copolymer (Ruviscol VA 82B, 73E, 64E, 55B,
37E: Manufactured by Yuka Pardish ■).

(a) The polymer compound is used alone or in combination of two or more, and is 0.1 to 10% by weight in the hair cosmetic composition.
It is appropriate to blend it, preferably in an amount of 0.2 to 5% by weight. If the blending amount is less than 0.1% by weight, the set retention property will decrease, while if it exceeds 10% by weight, the texture of the hair will tend to deteriorate.

The polysaccharide of component (b) is Acinetobacter type (
Examples include lipopolysaccharide produced by Acineto bacter, which is a type of so-called biosurfactant. Such lipopolysaccharide can be obtained, for example, from Petroferm (USA) under the trade name Emulsan.

This is a species of Acineto bacta (ATCC Deposit No. 310
12) is an extracellular microbial protein-associated lipopolysaccharide produced by α-emulsans (neo-emulsans) obtained mainly when ethanol is used as a carbon source; crude oil;
There are β-emulsans (protoemulsans) obtained when hexadecane is used as the main carbon source. Regarding the lipopolysaccharide produced by Acinetobacter type (ATCC deposited Nα: 31012), JP-A-55-1122
01 is described in detail.

(b) The polysaccharide has a weight ratio of (b)/(a) = 0.02/1 to 5/1 to the (a) polymer compound,
Preferably, a range of 0.02/1 to 2/1 is appropriate. If the blending ratio is lower than 0.02, the effect will not be noticeable, while if the blending ratio is higher than 5, a sufficient effect will not be obtained.

In addition to the above-mentioned essential ingredients, the hair cosmetic composition of the present invention may contain appropriate auxiliary ingredients, such as moisturizing agents such as sodium pyrrolidone carboxylate, cations, anions, amphoteric and Ionic surfactants, vitamins A, B, C, D, E, H1 oils, ultraviolet absorbers, disinfectants, cooling agents, heat sensitizers, pigments, etc. commonly used in cosmetics can be added. .

According to the present invention, a hair cosmetic is provided in which a polymer compound and a polysaccharide are used in combination, so that they act mutually, resulting in excellent set retention properties and giving a good texture to the hair. material composition can be realized.

The hair cosmetic composition of the present invention can be applied to various products such as setting lotions, hair sprays, styling agents, and hair lotions.

Next, the effects of the present invention will be specifically explained using examples. Prior to explaining each example, the test methods used in the examples will be described.

(1) Set retention (%) Wet a hair bundle of length 25G and weight 1.5g with water, remove the moisture with a towel, and then apply 0.3g of the prepared sample. Wrap this around the rod.

After drying with hot air at 70°C for 30 minutes, remove the hair bundle from the rod. Hang this hair bundle, immediately measure its length (assuming it is 2 degrees), leave it for 1 hour, then measure the length again.Q
,. Set retention (%) was calculated using the zero-order equation.

The closer it is to 100, the better the set retention is.

(2) Hair texture A sensory test was conducted by 20 panelists and evaluation was made according to the following criteria.
