Abstract
A cleanser composition contains (A) a nonionic surfactant having a HLB of from 10 to 18; and (B) a cosurfactant including at least one selected from the group consisting of alkylglycerols and glycerin fatty acid esters. A content of the cosurfactant is 0.3% by mass or greater relative to the mass of the cleanser composition. A total amount of ionic surfactants is 0.10% by mass or less relative to the mass of the cleanser composition.
Claims15
A cleanser composition comprising:
- (A) a nonionic surfactant having a HLB of from 8 to 18;
- and
- (B) a cosurfactant including at least one selected from the group consisting of alkylglycerols and glycerin fatty acid esters, and
- (C) 70% by mass or greater of water relative to the mass of the cleanser composition, wherein:
- the nonionic surfactant is at least one of PEG-60 glyceryl isostearate, PEG-20 glyceryl triisostearate, PEG-8 glyceryl isostearate, PEG-7 glyceryl cocoate, and PEG-15 glyceryl isostearate,
- wherein:
- a content of the nonionic surfactant is 1% by mass or greater relative to the mass of the cleanser composition,
- a content of the cosurfactant is 0.3% by mass or greater relative to the mass of the cleanser composition;
- a total amount of the cosurfactant is from 0.1 to 0.9 parts by mass relative to 1 part by mass of the nonionic surfactant;
- the nonionic surfactant assembles together in water to form a continuous assembly, and the hydrophilic groups of the continuous assembly retain water to form a sponge phase;
- and
- a total amount of ionic surfactants is 0.1% by mass or less relative to the mass of the cleanser composition.
