Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to shampoo compositions. More specifically, a conditioning shampoo composition that imparts strength, smoothness, etc. to washed hair is characterized by containing a water-soluble chain polymer compound with an average degree of polymerization of 5,000 to 20,000 and a plant extract. I'm concerned.

A conventional 7-Yanbu composition includes an alkyl sulf-m-) salt,
Anionic surfactants such as oxyethylene alkyl sulfate salts: Nonionic surfactants such as polyoxyethylene alkyl ethers and fatty acid alkylolamides: Zwitterionic surfactants such as argyl betaine and alkyl amine oxides They are used alone or in combination of two or more as a base. However, these shampoo-based shampoo compositions excessively wash away sebum and other oils present in the hair, making the hair feel very bad after washing and making it difficult to pass through with a comb or brush. When the hair is completely dry, the hair is difficult to manage, especially in the winter when there is low humidity, static electricity is generated when brushing, causing phenomena such as hair fries, causing the hair to tangle with each other, and as a result, it becomes even more It has the disadvantage that combs and brushes don't go through well, causing it to curl, which eventually manifests itself as split ends and breakage. In addition, a method of adding oil to a general shampoo base to supplement oil during hair washing is known from the prior art.
Various oils are added to conventional shampoos. However, the amount of these oils added is limited, and in shampoo systems they are naturally emulsified or solubilized by surfactants, making it difficult to leave a sufficient amount of oil on the scalp and hair. Furthermore, if a large amount of oil is added, the amount of oil adsorbed to the hair will increase, but the foaming and cleaning power, which are the original functions of shampoo, will be extremely impaired, and the product value will be significantly impaired.

On the other hand, in recent years, many shampoo compositions containing cationic polymers and the like have been proposed for the purpose of imparting a rinsing effect to hair after washing, but many of these have various drawbacks as described below. For example, some products have a conditioning effect but have poor foaming properties and detergency, others cause coloration or discoloration when administered orally, some products have excellent foam properties but have poor conditioning effects, and some have fatal flaws such as high cost. .

The present inventors have conducted intensive research on developing a shampoo composition that improves the shortcomings of conventional shampoo compositions and has a conditioning effect that makes hair supple and smooth after washing. By using these polymer compounds and plant extracts in combination, the original performance of the shampoo composition is not impaired (1) (the hair feels supple and smooth after washing, and it feels smooth when combed). The present invention has been completed based on the discovery that it is possible to impart excellent conditioning effects such as hydration.

That is, the present invention has an average degree of polymerization of 5,000 to 20.00.
The present invention provides a shampoo composition containing a water-soluble chain polymer compound of 0.0 and a plant extract.

Average degree of polymerization s used in the present invention, ooo ~ 20,000
The water-soluble chain polymer compound is a synthetic polymer compound, and includes polyvinyl alcohol, polyvinyl alcohol maleic anhydride partial ester, maleic anhydride/methyl vinyl ether copolymer, maleic anhydride/diisobutylene copolymer, and polyacrylic. Examples include acids or salts thereof, polyacrylamide copolymers, maleic anhydride/methyl vinyl ether copolymers, polyethylene oxide, vinyl acetate/maleic anhydride copolymers or salts thereof, partially saponified polyacrylic esters, polyvinylpyrrolidone, etc. Among these, polyacrylic acid or a salt thereof or polyvinylpyrrolidone is preferred. Examples of the salt in this case include alkali metal groups such as sodium and potassium, ammonium, and alkanolamine groups having an alcohol residue having 2 or 3 carbon atoms, and sodium salts are particularly preferred.

The average degree of polymerization of the water-soluble chain polymer compound is 5,000
-20,000; if the average degree of polymerization is less than 5,000, the properties of the foam will deteriorate and the average degree of polymerization will be 20,000.
If it exceeds 00, foaming will occur and the slippage of the foam will deteriorate, which is not preferable.

The water-soluble chain polymer compounds having an average degree of polymerization of 5,000 to 20,000 are used alone or in an appropriate mixture of two or more, and also contain KO,005 to 2% by weight in the shampoo composition.
