Abstract
Personal care composition having improved compatibility and providing improved sun protection are obtained by including a liquid silicone resin having greater than 50 mole percent Me3SiO1/2 and PrSiC3/2 units, where Me is methyl and Pr is propyl in the composition. If desired to enable additional compatibility of ingredients comprising the personal care composition, the liquid silicone resin can also contain PhSiO3/2 or Ph2SiO2/2 units, where Ph is phenyl, or a mixture thereof.
