  • Patent number: 9044413
    Abstract: The present invention relates to a block polymeric material. Typically the block polymer comprises units capable of having an average cationic charge density of about 15 or less, preferably 5 or less, more preferably from about 0.05 to about 5, even more preferably from about 0.05 to about 2.77, even more preferably from about 0.1 to about 2.75, most preferably from about 0.75 to about 2.25 units per 100 daltons molecular weight at a pH of from about 4 to about 12. The polymeric material is a suds enhancer and a suds volume extender for personal care products such as soaps and shampoos. The compositions have increased effectiveness for preventing re-deposition of grease during hand and body washing. The polymers are also effective as a soil release agent in fabric cleaning compositions.

  • Patent number: 7820752
    Abstract: The invention concerns the use as thickening agent of an aqueous composition comprising at least 5 wt. % of one or several phase-organized surfactant(s) comprising giant micelles whereof the average length represents at least four times the mean diameter, of at least a charged statistic amphiphilic polymer soluble in the aqueous composition, said amphiphilic polymer being used in a content such that the viscosity of the aqueous composition comprising the amphiphilic polymer is at least three times higher than that of the composition without amphiphilic polymer and than that of an aqueous composition comprising only the amphiphilic polymer. The invention also concerns aqueous compositions comprising said amphiphilic polymer, and are particularly designed for cosmetic uses.
