The invention relates to use of specifically defined polydextrose to induce biphasic liquid formation. Optional use of salt allows less polydextrose to be used to induce biphasic formation.
Claims10
A liquid cleansing composition comprising:
- (a) about 5% to 75% by wt. of a surfactant selected from the group consisting of anionic surfactants, nonionic surfactants, amphoteric/zwitterionic surfactants, cationic surfactants and mixtures thereof;
- (b) at least about 15% of a polydextrose molecule or molecules, wherein the degree of polymerization is about 4 to about 22 (corresponding to MW of about 600 to about 3600);
- and
- (c) balance water and minors;
- wherein said composition comprises at least two visibly separated aqueous based layers when left sitting without shaking or stirring.
