ABSTRACT:
FIELD OF THE INVENTION
This invention relates to a cleanser composition, in particular, to shampoo, and further to that of good bubble forming property and low irritating to eye mucous membranes and skin.
BACKGROUND OF THE INVENTION AND PRIOR ART
Conventionally, polyoxyethylene-alkylsulfate-type anionic surfactants are generally used as a main ingredient of cleanser composition, especially, shampoo. The surfactants have been very useful as main components for especially shampoo because of good bubble forming property and good bubble feeling.
However, the shampoo containing polyoxyethylene-alkylsulfate-type anionic surfactants as a main component is irritating to eye mucous membrane or skin, and inappropriate to shampoo for baby or child use.
SUMMARY OF THE INVENTION
The inventor has sought to solve the problems, and accomplished this invention. Thus the present invention relates to a cleanser composition comprising sulfosuccinate-type anionic surfactants; polyoxyethylene-alkylsulfate-type anion surfactants; one or more than two amphoteric surfactants selected from the group consisting of imidazoline-type amphoteric surfactants, amidobetaine-type amphoteric surfactants and alkylbetaine-type amphoteric surfactants; and polyoxyethylene-sorbitan-type nonionic surfactants; characterized by containing, based upon the total weight of the composition: from about 1 to about 15% of sulfosuccinate-type anionic surfactants; from 0.1 to 4% polyoxyethylene-sorbitan-type nonionic surfactants; and wherein:
the weight ratio of sulfosuccinate-type anionic surfactants to polyoxyethylene-alkylsulfate-type anionic surfactants is about 1:0.25 to about 1:2, and the weight ratio of sulfosuccinate-type anionic surfactants to total amount of imidazoline-type amphoteric surfactants, amidobetaine-type amphoteric surfactants and alkylbetaine-type amphoteric surfactants is about 1:0.25 to about 1:2.
