Description

The present invention relates to a shampoo composition, and more particularly, foaming is good when shampooing, excellent slipperiness so that the hair does not get tangled, no squeaky hair when rinsing, excellent fingering property, and the hair does not clump after use. Are related to shampoo compositions having good stability.

In recent years, hairstyles and hair colors have come to be enjoyed as fashion, and hair coloring and permanents have become commonplace. The hair is damaged by hair color and perm, etc., causing problems such as tangling hair during shampooing, touching badly when rinsing, and tangling hair when towel drying after washing doing. For this reason, in addition to the original cleanability, shampoo is required to have a good finish such as smooth foaming, good fingering during rinsing, no loose hair after washing, and good cohesion. ing. Conventionally, as a method for improving the good fingering of hair during washing and rinsing, cationized guar gum, cationized cellulose or dialkyldiallyl quaternary ammonium salt is used as a washing base such as anionic surfactant and amphoteric surfactant. -Combining cationic polymers such as acrylamide copolymers is widely used (see, for example, Patent Documents 1 to 4).

It is also known to add a cation / amphoteric polymer (methacryloylethyldimethylbetaine / methacryloylethyltrimethylammonium chloride / methoxypolyethyleneglycol methacrylate) copolymer to shampoo composition, and it has conditioning and hair-styling effects on hair. (For example, refer to Patent Documents 5 and 6). These technologies are blended with (methacryloylethyldimethylbetaine / methacryloylethyltrimethylammonium chloride / methoxypolyethyleneglycol methacrylate) copolymer alone. However, the touch was not fully satisfactory, and a complex was formed with the anionic surfactant, resulting in precipitation, and it was difficult to mix stably.

In order to prevent deterioration of the conditioning effect due to shampooing, the water-soluble inorganic salt is incorporated in an emulsified hair treatment agent in combination with a cationic surfactant and a nonionic polymer (see, for example, Patent Document 7). ), Water-soluble inorganic salts are not intended for stable blending of polymers, and are limited to combinations of nonionic polymers and water-soluble inorganic salts to stabilize the blending of cationic / amphoteric polymers. Was not known about.

It is known to add coconut oil fatty acid N-methylethanolamide to a shampoo for the purpose of improving foaming and storage stability (see, for example, Patent Documents 8 and 9), but (methacryloylethyldimethylbetaine / chloride). It has not been known that when combined with a shampoo in combination with (methacryloylethyltrimethylammonium / methoxypolyethyleneglycol methacrylate) copolymer, it exhibits excellent fingering during shampooing and rinsing.
