COMPOSITION AND METHOD OF PRODUCING PERSONAL CARE COMPOSITIONS WITH IMPROVED DEPOSITION PROPERTIES

摘要

The presently disclosed and/or claimed inventive concept(s) relates generally to the use of nonionic hydrophobically modified polysaccharides in personal care and household care compositions. More specifically, but not by way of limitation, the presently disclosed and/or claimed inventive concept(s) relates to the use of hydrophobically-modified cellulose ethers, such as hydrophobically-modified hydroxyethylcellulose (HMHEC) polymers in personal care and household care compositions. These compositions show pronounced syneresis in aqueous solutions or in the presence of surfactants, including nonionic surfactants and anionic surfactants such as lauryl sulfate (LS) and lauryl ether sulfate (LES). It is also contemplated that the surfactants used in the compositions be sulfate free and/or multi-tailed.

主权项

1. A composition for conditioning a functional system substrate comprising an aqueous solution, comprising:
a. at least one sulfate-free multi-tail surfactant and at least one sulfate-free single-tail surfactant; b. at least one functional system active ingredient; and c. a nonionic hydrophobically modified cellulose ether having a weight average molecular weight of from 100,000 to 2,000,000 that is hydrophobically substituted, wherein the composition is substantially free of sulfate-containing surfactants, and wherein the amount of hydrophobic substitution of the nonionic hydrophobically modified cellulose ether is in a range from a lower limit of 0.8 weight percent to an upper limit rendering the nonionic hydrophobically modified cellulose ether soluble in a five weight percent solution of surfactant, and at least one of (1) less than 0.5 percent by weight soluble in water, and (2) less than 0.05 percent by weight soluble in a one percent surfactant solution, wherein upon diluting the aqueous solution with water, the aqueous solution undergoes syneresis, whereby the nonionic hydrophobically modified cellulose ether separates from the aqueous solution and deposits upon the functional system substrate.
