This article is willing to show through different industrial examples the role played by the oleochemistry in the development of new surfactants. This field offers indeed a large choice of alkyl chains that can be transformed. Linked to a polar head such as a polyol, a carbohydrate or a protein derivative, these alkyl chains lead to performing bio-surfactants that show interesting toxicological and ecotoxicological profiles. This natural lipophilic source allows thus to adjust some physico-chemical parameters of the surfactant such as its geometry, its hydrophilic lipophilic balance, the type of functional groups linking its hydrophilic part to its lipophilic part, its molecular weight, etc. The emulsifying, foaming, solubilizing, biological properties can be valued in cosmetics (as excipients or actives), in the areas of veterinary additives, of detergents, in the food industry, etc.
Key words: oleochemistry / natural lipophilic source / hydrophilic lipophilic balance / polyol
