Disclosed are dry-feel emollient compositions comprising fatty alcohols, alkyl esters and jojoba wax esters obtained by a novel process of a base catalyzed alcoholysis reaction between jojoba oil and an alcohol, such as isopropyl alcohol. The composition is essentially solid at room temperature, can be provided in various shapes and sizes (especially as particulates such as spheres). These new compositions increase the range of applications for cosmetic compositions by providing an emollient that is more polar and hydrophilic than is found in naturally occurring jojoba oils (jojoba wax esters). These compositions have use in personal care, cosmetic, cosemceutical and pharmaceutical products. Typical materials these compositions may be blended include, but are not limited to, cosmetic oils and waxes, both natural and synthetic, hydrogenated or partially hydrogenated oils, silicone oils, mineral oils, long chain esters, vitamins, long chain fatty acids, alcohols, cosmeceuticals, pigments, botanical extracts, esters and ethers, dimers, trimers, oligomers, polymers, and the like. These compositions may be combined with active ingredients to be delivered by the compositions.

Dry emollient composition composing mono-unsaturated jojoba esters

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 not limited to, cosmetic oils and waxes, both natural and synthetic, (including hydrogenated or partially hydrogenated oils), silicone oils, mineral oils, long chain esters, vitamins, long chain fatty acids, cosmeceuticals, pigments, botanical extracts, esters and ethers, dimers, trimers, oligomers, and polymers, and the like. The proportions of the jojoba esters should be chosen to provide the dry-feel to the composition, which is highly desired. This will usually require a weight percent that ranges from 10% to 100% by weight of carrier material in the composition.
