Materials with high levels of unsaponifiable matter, such as extracts from plants, produce hydrolysates with unique properties. Properties that are sought in traditional saponification of natural oils are a result of low levels of unsaponifiables. These properties include high levels of aqueous surfactant activity, water-solubility or ready water- dispersabilhy, activity as foaming agents, and the like. An objective of traditional saponification processes is to increase the water-solubility and surfactant activity of naturally occurring materials. It has been found that the application of a hydrolysis process to materials, particularly materials with a high level of unsaponifiables (e.g., at least 6% by total weight of the material), produces a product with properties significantly different horn those products resulting from the conventional saponification of materials with less than 6 % by weight of unsaponifiables. The resulting hydrolysates horn the practice of the present invention, are substantive, resisting both physical and aqueous-based removal from skin and hair, exhibit a very unique surfactant property, and are not foaming agents with water, hydrolysates according to the present invention may thus be used to enhance the performance of cosmetics and pharmaceuticals. These hydrolysates can be are bioactive agents and alternative natural carrying agents for topical application of materials, particularly for application of materials to the skin or hair of subjects, and provide a substantive support for the materials carried.Les matières possédant des taux élevés dinsaponifiables, telles que les extraits de plantes, produisent des hydrolysats présentant des propriétés uniques. Les propriétés qui sont recherchées dans la saponification classique dhuiles naturelles résultent de faibles taux dinsaponifiables. Ces propriétés comprennent des taux élevés dactivité tensio-active aqueuse, lhydrosolubilité ou lhydrodispersabilité facile, lactivité dagents moussants et
