Abstract
Novel silicone compounds containing a siloxane moiety and at least one terpenyl moiety, such as limonenyl or valencenyl, and methods for their synthesis, are provided. The novel compounds are appropriate for incorporation into cosmetic formulations due to their low aroma, resistance to deterioration, and favorable solubility properties.
