ABSTRACT
Skin feel additives are substances conferring sensorial properties to a skin care product, triggering pleasant perception during application onto the skin and after use. Effectiveness of sensory triggers is governed by their substantivity to the skin which occurs either by hydrophobic interaction or by charge attraction or a combination of these two factors. A large variety of cosmetic ingredients function as skin feel/ conditioning additives comprising lipophilic materials, silicones, water soluble polymeric substances (including proteins) and their cationic derivatives, humectants, etc. The Cosmetic, Toiletry and Fragrance Association (CTFA) divides skin conditioning agents into various groups: emollients, occlusive materials, and miscellaneous substances including, among others, cationic macromolecules and several surfactants.
