Description

Conditioning shampoo composition {Conditioning shampoo composition}

The present invention relates to a conditioning shampoo composition, and more particularly, to a conditioning shampoo composition having excellent cleansing and foaming power, which is a shampoo's inherent function while maintaining transparency, and having excellent conditioning effect and low irritation to skin or scalp. .

Shampoo, a hair cleaner, makes hair clean by removing contaminants and sebum from the hair and scalp, but the shampoo process removes the moisturizing ingredients of the sebum and hair, making the hair soft and dry, making the hair tangled and difficult to handle. In rare cases, keratin, dandruff, and inflammation may be caused by irritation by surfactants or conditioning agents included in shampoos.

It is common industry opinion that sulfate-based surfactants, which are widely used as human cleansers, have recently become more sensitive to the scalp due to environmental pollution and lifestyle changes, causing them to be irritating to these consumers.

Since betaine, one of the amphoteric surfactants, has a low likelihood of irritation, it has been widely used in the 1970s to improve the amount of bubbles and adjust the physical properties of shampoos, bath bubbles, and liquid soaps. However, “Clinics in Dermatology (1996; 14: 67-76, 1997; 15: 485-491)”, “Journal of American Academy of Dermatology (vol. 27, number 6, part 1, December, 1992)”, “ According to the American Journal of Contact Dermatitis (vol. 12, issue 4, December, 2001, p. 223-224) ”, for the first time in 1984, the symptoms of contact hypersensitivity caused by cocamidopropylbetaine used in shampoos were discovered. Similar symptoms have since been reported to be caused by cocamidopropyl betaine. The Journal of American Academy of Dermatology (vol. 60, number 1, January, 2009) also reports the case of allergic reactions by 1% cocamidopropylbetaine.

In order to supplement the conditioning effect of the shampoo, the general opaque shampoo is included in the hair conditioner to increase the flexibility of the hair. However, in the case of clear shampoos, the formulation becomes opaque when using conventional hair conditioning agents, which limits the conditioning ingredients to be added. In addition, hair conditioning agents can remain in the scalp and cause irritation.

U.S. Patent No. 5,514,369 proposes a mild shampoo composition containing alkylpolyclycoside as the main surfactant, but when it is based on alkylpolyclycoside, the amount of air bubbles is insufficient and the conditioning effect is not satisfactory. There is a lack of weakened scalp. US patent application US2002 / 0173435 proposes a mild shampoo composition comprising a cocamido polypropylene derivative, but there is a shortage of mild shampoo since it is still considering an increase in bubble power through cocamidobetaine.

An object of the present invention to solve the above problems is to provide a conditioning shampoo composition having excellent cleansing power and foaming power, which is a natural function of the shampoo while maintaining transparency and not only excellent conditioning effect but also less irritation to the skin or scalp. .
