  • Patent number: 6610279
    Abstract: This invention relates to an anhydrous cosmetic composition comprising: (a) 15-33% of an external phase (also called the oil phase) which is made with at least one selected naphthalate organic ester; a volatile silicone based emulsifier; and a volatile silicone; and (b) 85-67% of an internal phase which is made with an active ingredient, such as an antiperspirant active, in a glycol solvent. For the external phase all or a major portion of what would have been a non-volatile silicone component has been replaced by the naphthalate ester. While a dimethicone copolyol is still included, the use of this particular naphthalate ester obviates the need for the use of any other non-ionic emulsifiers.
