  • Patent number: 8529970
    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.

  • Patent number: 6365199
    Abstract: A hair growth formulation. The two basic main ingredients are castor oil and a special lemon extract. The special lemon extract is made from fresh lemon peel. The peel, including the bioflavonoids membrane, is blended with purified water until it is liquidified. Then the mixture is filtered through a sanitized cloth. Other ingredients that have been found helpful include: inositol, choline (from bitartate), niacinamide or nicotinic acid, manganese in chelated form, bioflavonoids, and folic acid. Finally perfume and sodium benzoate (as a preservative) can be added.
