  • Patent number: 6028043
    Abstract: Liquid personal cleansing compositions which comprise a complex coascervate, a lipophilic skin moisturizing agent, a stabilizer, a lathering surfactant and water are disclosed. The complex coascervate comprises particles having a particle size distribution such that at least about 10% by weight of the particles have a diameter of at least about 20 microns. The particles comprising the complex coascervate comprise 1) a polycation having a minimum filtrate with of about 10 grams, and 2) a polyanion. The complex coascervate is essentially free of cross-linking agent.

  • Patent number: 5932528
    Abstract: Liquid personal cleansing compositions which comprise from about 1% to about 35% of encapsulated lipophilic skin moisturizing agents, from about 0.1% to about 5% of a stabilizer, from about 5% to about 30% of a lathering surfactant and water are disclosed. The encapsulated lipophilic skin moisturizing agent comprises a lipophilic skin moisturizing agent encapsulated within a complex coascervate comprising a polycation and a polyanion. The lipophilic skin moisturizing agent comprises droplets having a particle size distribution such that at least about 10% by weight of the droplets have a diameter of at least about 100 microns. The encapsulated lipophilic skin moisturizing agent is essentially free of cross-linking agent.
