ABSTRACT:
Described are controlled, time-release microparticulate active and bioactive compositions (including perfuming compositions) for targeted delivery to surfaces such as skin, hair and fabric and the environment proximate thereto, where the active and bioactive materials have a calculated log.sub.10 P values of between 1 and 8 (P being the n-octanol-water partition coefficient). Such compositions include the active or bioactive material in single phase, solid solution in a wax or polymer matrix also having coated thereon and/or containing a compatible surfactant. Also described are processes and apparatus for preparing such compositions and processes for using same. Furthermore, certain component(s) of the aforementioned compositions in combination with one another are novel, and other components have novel uses in increasing fragrance substantivity, particularly in hair care preparations such as hair gels and shampoos.
