Abstract
The invention relates to a series of novel propoxylated silicone rosin esters. This class of compounds provides unique solubility in organic solvents like iso-paraffin, and despite its lack of water solubility, provides an ability to couple water into anhydrous systems like lipsticks, minimizing the incompatibility that causes syneresis.
