Description

Shampoo composition {SHAMPOO COMPOSITION}

The present invention relates to a shampoo composition.

BACKGROUND ART Conventionally, techniques for imparting pearl gloss to shampoo and the like have been widely performed to increase the value of a product. A method for producing a dispersion for imparting pearl luster to shampoo and the like (see, for example, Patent Documents 1 and 2) A shampoo composition having luster and a method for producing the same (for example, refer to Patent Documents 3 to 5) are known.

Such a shampoo composition having a pearl luster has a problem that stability of the pearl luster and dispersion uniformity of the pearling agent particles are lost under long-term storage or high-temperature environment. In order to solve the above problem, for example, there has been proposed a method in which isoprene glycol is added to an aqueous system of a thickened anionic surfactant to stably disperse the pearlizing agent (see Patent Document 6), a method in which xanthan gum and cationic polymer (See Patent Document 7), a method of containing 3-alkyl (C10-20) oxy-2-hydroxypropylarginine and / or a salt thereof together with a pearlizing agent (see Patent Document 8) (Refer to Patent Document 9), a method of melting a pearling agent having a higher proportion of fatty acids having a higher number of carbon atoms constituting the ester than the pearling agent and then cooling it to precipitate the pearling agent (see Patent Document 9) A shampoo composition which crystallizes a pearlizing agent by adding a polymer and a specific production method (see Patent Document 10), and the like have been proposed.

On the other hand, if a large amount of a pearlizing agent is blended into the shampoo composition, the foam diary or foam performance of the shampoo may be deteriorated. To solve this problem, for example, a method has been proposed in which a premix is prepared by adding a long-chain fatty acid glycol ester dispersion as a separately prepared perlating agent to an aqueous solution of a cationic polymer, and then mixing the premix with the other detergent components (See Patent Document 11).

It is also known that the pearlizing agent in the shampoo composition influences the feel of hair after shampooing as well as the foaming diarrhea. A detergent composition containing pearl luster particles of a specific particle diameter obtained from a pearl luster composition having a specific composition has a volume And the slip property of the hair is improved (see Patent Document 12).

However, the pearlizing agent is dispersed in the shampoo composition to exhibit a good luster, and stable pearl luster can be obtained even under high temperature conditions, and the dispersion uniformity of the pearlizing agent can be maintained. In addition, the texture during rinsing of the shampoo, It is in the present state that no shampoo composition with a good easiness of styling during drying is provided.
