Abstract:
The invention provides personal care products that do not contain D4 and/or D5 cyclomethicones but which do have the skin feel, spreadability, and other physical and chemical characteristics of personal care products that do contain these cyclomethicones. The products of the invention include a neopentyl polyol polyester(s) derived from neopentyl glycol, an isoparaffin(s), and a personal care formulation. Also included are replacement compositions for use in personal care products (so that D4 and D5 cyclomethicones can be excluded from the formulation) and methods of preparing personal care products and replacement compositions.

The invention includes a diester exhibiting improved hydrolytic stability that is an esterification product of a 1-methylheptyl alcohol and a dicarboxylic acid. In some embodiments, the diester is bis(l-methyl heptyl) butanedioate, bis(l-methyl heptyl) nonanedioate and/or bis(l-methyl heptyl) decanedioate. The diester may be natural and/or not sourced from palm. Also contemplated within the scope of the invention are diesters exhibiting improved hydrolytic stability represented by Formula (I) wherein R1 is chosen from a linear alkyl group containing four to ten carbonatoms. Also included are personal care compositions comprising any of these diesters and methods of preparing a personal care composition using the inventive diesters, and/or methods of altering the tactile impression and/or skinfeel provided to a user by a personal care composition by combining any of the diesters of the invention and at least one personal care component to form a personal care composition; and topically applying the personal care composition to the hair, skin, and/or nails of a user.
