Abstract
The invention relates to the use of specifically defined agents that induce the formation of biphasic liquid cleansing compositions. In particular the biphasic inducing agents include water soluble, high-gel-point polysaccharides having a molecular weight greater than about 10,000 Daltons; fatty ester or fatty ether ethoxylates of intermediate ethoxylation; and mixtures thereof. Optional use of salt and polydextrose allows less total biphasic inducing agents to be used in the composition and more control over the physical properties of the composition.
Claims12
A liquid cleansing composition comprising:
- a) about 5% to about 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) a Biphasic Inducing Agent selected from the group consisting of high-gel-point polysaccharides having a molecular weight greater than about 10,000 Daltons;
- intermediate ethoxylate fatty esters or fatty ethers;
- and mixtures thereof;
- c) from 0 to about 10% of a salt;
- d) from 0 to about 35% of a polydextrose;
- wherein the amount of biphasic inducing agent is sufficient to produce at least two visibly separated aqueous based layers when the compositions are left undisturbed without stirring or shaking or other agitation.
