Publication date: Jan. 11, 2011
Assignee: Rhodia Inc.

This invention uses mono-, di- and polyol phosphate esters, e.g. PEG phosphate esters, PPG phosphate esters, and glycerin phosphate esters, to provide multiple benefits to typical personal care formulations. These molecules are adsorbed onto the skin from a formulation as they are applied and render many various benefits. The concentrations in which they may be used can vary depending on the intended purpose and the amount of benefit desired. A hydrophilized personal care formulation is described that can be in the form of a hand or body soap (liquid or bar), lipstick, body wash, makeup remover, skin cleaner, hair conditioner, skin or hair moisturizer.
