  • Patent number: 4818522
    Abstract: Antiperspirant formulations are provided in which water-immiscible adjuvants are encapsulated in thick-walled, hollow, substantially spherical particles of antiperspirant active, which is preferably a water-soluble compound or complex of a polyvalent metal or metals. The thick-walled particles resist rupture during normal handling and application of the antiperspirant formulation and provide slow release of the encapsulated adjuvant when the antiperspirant shell dissolves in perspiration. The adjuvant may be a fragrance, an antibacterial, antimicrobial or antifungal agent, a deodorant, or other dermatological preparation. The encapsulation is accomplished by emulsifying the adjuvant in an aqueous solution of the antiperspirant active, and spray drying the material in such a manner as to produce thick-walled, spherical particles with the liquid adjuvant in the hollow centers.
