Novel Cosmetic Delivery Systems

Shlomo Magdassi, Elka Touitou

Skin and cosmetic vehicles - cosmeceutics and delivery systems; the skin and its permeability; enhancement of permeation; skin hydration. Evaluation of cosmetic products - assessing the bioactivity of cosmetic products and ingredients; stability testing of cosmetic products; quantitation of penetrant molecules within the skin. Emulsions and surfactant association structures - multiple emulsions; highly concentrated water-in-oil emulsions (gel emulsions); fluorocarbon gels; vapour pressure of fragrances after application -some fundamental factors. Vesicular and molecular systems - liposomes; liposomes and follicular penetration; cyclodextrins in cosmetics. Particulate systems - microcapsules in cosmetics; applications of polyvinyl alcohol microcapsules; delivery by nylon particles.
