Benefits of technology

[0011]High molecular weight polymers are generally difficult to dissolve and difficult to distribute homogeneously in aqueous formulations. Therefore, another solution is desired. More specifically, there is a need in the art for aqueous surfactant based systems with reduced amount of chemicals to obtain a certain viscosity or compositions with a higher viscosity wh

Abstract

Personal care compositions, methods for making and uses thereof include an aqueous viscoelastic composition and a personal care active ingredient. The viscoelastic composition includes at least one surfactant and at least one hydrophobically-modified polymers with low molecular weights.

Description

FIELD OF THE INVENTION[0001]The present invention relates to personal care compositions comprising aqueous viscoelastic compositions comprising at least one viscoelastic surfactant, and at least one hydrophobically modified polymer.BACKGROUND OF THE INVENTION[0002]It is noted that WO 2003 / 056130 proposes an improvement on such existing systems and proposes to use a combination of viscoelastic surfactants and a hydrophobically modified polymer, wherein the concentration of the hydrophobically modified polymer is comprised between its overlap concentration c* and its entanglement concentration ce. Although the viscoelastic fluids of WO 2003 / 056130 have certain commercial value, they contain high amounts of both surfactant and hydrophobically modified polymer in order to achieve aqueous compositions with the desired viscosity. Further, in the polymer, the hydrophobes are connected to the polymer backbone via a degradable group.[0003]It is noted that also in U.S. Pat. No. 4,432,881 liqu...
