Abstract
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-dispersability, 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 weight percent of the material), produces a product with properties significantly different from those products resulting from the conventional saponification of materials with less than 6 weight percent of unsaponifiables. The resulting hydrolysates from 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 th…
