Abstract
The present invention are dry-feel emollient compositions comprising jojoba oil based esters that have use in personal care, cosmetic, cosmaceutical and pharmaceutical products. These compositions are essentially solid at room temperature, can be provided in various shapes and sizes (especially as particulates such as spheres), and can be produced from combinations of fatty alcohols, isopropyl esters and wax esters obtained from the oil contained in the seed of the jojoba plant. These new compositions also increase the range of applications for cosmetic compositions through an emollient that is more polar and hydrophilic than is found in jojoba oils. The compositions of the present invention may be obtained by a novel process of a base catalyzed alcoholysis reaction between jojoba oil and an alcohol, such as isopropyl alcohol. These components, whether exclusively jojoba esters or when combined with other carrier and vehicle components (including other emollients or binders) can form excellent carrier composition for use in the cosmetic, personal care and/or pharmaceutical field. Typical materials with which the compositions of the present invention may be blended include, but are …
