ABSTRACT:
The present invention provides a liquid silicone ester having a melting point of up to about 30.degree. C., and comprising (A) units of the general formula R.sub.a R.sup.E.sub.b SiO.sub.[4-(a+b)]/2 or (B) R.sub.x R.sup.E.sub.y SiO.sub.1/2 units and SiO.sub.4/2 units; R.sup.E being an ester-containing organic group. The silicone ester is liquid at ambient skin temperature and has improved workability, improved payout, improved emollient properties, greater solubility in organic compounds, greater substantivity to surfaces and improved water resistance.
