Also provided is a method of using a personal care composition.

Personal care composition

A hydrophobically modified rheology modifier comprising:

Hydrophobically modified acrylic rheology modifiers having high carbon number hydrophobes

Provided is a concentrated emulsion and personal care compositions containing the concentrated emulsion. The emulsion comprises: (a) from 60 to 95 wt %, based on the total weight of the emulsion, of an internal phase comprising: (i) a low density polyolefin with a density equal to or below 0.90 g/cm, and (ii) a cosmetically acceptable solvent; (b) from 0.1 to 30 wt %, based on the total weight of the emulsion, of a surfactant; and (c) balance water as a continuous phase.

Concentrated polyolefin emulsions and personal care compositions containing them

The present invention provides personal care formulations containing silicone modified polyolefins and having improved sensory feel, as well as being non-tacky and easily spreadable. The present invention also provides a method for treating body surfaces such as skin, hair, nails, etc., by applying the aforesaid personal care formulations externally to such a surface. The present invention also provides a method for improving the sensory feel of personal care formulations by including one or more silicone modified polyolefins in the formulations.

Silicone modified polyolefins in personal care applications

Described are personal care, preferably skin care compositions, comprising polyolefin blends comprising at least one metallocene catalyzed polyolefin with a density above 0.90 g/cm, at least one metallocene catalyzed polyolefin with a density equal to or below 0.90 g/cm, provided that the average melt index for the polyolefin blend is greater than 7; and a cosmetically acceptable hydrocarbon oil, provided that the composition does not contain ethylene acrylic copolymer.

Personal care sensory agents

Described are personal care compositions comprising a polymer comprising: (a) one or more polymer comprising, as polymerized units, (i) 75% to 35% by weight, based on the weight of said polymer, one or more (meth)acrylate monomer selected from at least one of C1-C4 (meth)acrylate, (meth)acrylic acid, styrene, or substituted styrene, and (ii) 25% to 65% by weight, based on the weight of said polymer, one or more hydrophobic monomer, including hydrophobically substituted (meth)acrylate monomers, with alkyl chain length from C8 to C22 and, (iii) optionally crosslinker, and, (b) at least one personal care active. Optionally, the polymer further includes a stage 2 polymer comprising, as polymerized units, (i) 10-99% of one or more monomer which has a Tg of more than 80&#xb0; C. after polymer formation, (ii) 1-10% of one or more (meth)acrylate monomer containing acid functional group, and (iii) optionally, a crosslinker.
