Abstract: Provided are compositions that are useful as oil-free emollients in personal care formulations. The emollients are oil-soluble polyalkylene glycols, wherein the polyalkylene glycol comprises units derived from propylene oxide and units derived from butylene oxide, and in certain embodiments are compounds of Formula I: RO—(PO)n—(BO)m—H  (I) wherein PO is propyleneoxy, BO is butyleneoxy, R is a linear or branched C8-C20 alkyl, n has an average value of from 5 to 20, and m has an average value of from 4 to 16.

Abstract: Provided are personal care compositions comprising (A) voided latex particles comprising (i) at least one core polymer comprising polymerized units derived from monoethylenically unsaturated monomers containing at least one carboxylic acid group, and non-ionic ethylenically unsaturated monomers, and (ii) at least one shell polymer comprising polymerized units derived from non-ionic ethylenically unsaturated monomers, and polyethylenically unsaturated monomers, and (B) pigment grade inorganic metal oxide particles, wherein the voided latex particles contain a void and have a particle size of from 400 nm to 800 nm. Also provided are methods for lightening skin tone comprising topically administering such compositions to the skin, and methods for improving visible light scattering of a composition including a pigment grade inorganic metal oxide particle comprising adding to such composition a voided latex particle.

Abstract: The present invention provides personal care formulations containing silane functionalized polyolefins and having improved sensory feel, as well as being non-tacky and easily spreadable on skin. The present invention also provides a method for treating the body by applying the aforesaid personal care formulations externally to the body. The present invention also provides a method for improving the sensory feel of personal care formulations by including silane functionalized polyolefins in the formulations.
