Smooth-feeling wax-based compositions for personal care preparations
View Patent ↗A smooth, dry-feeling, less-greasy, substantially-odorless, ecotoxicologically-safe, wax-based composition with a melting point above 25° C., comprising one or more wax components selected from dialkyl carbonates, dialkylene carbonates, and mixtures of two or more thereof; less than 10%, by weight, of water; and (c) optionally, one or more components selected from the group consisting of one or more wax or oil components selected from the group consisting of dialkyl ethers, dialkylene ethers, dicarboxylic acids, hydroxyfatty alcohols, and mixtures of two or more thereof, as well as one or more wax-like lipid components, other than those in previously listed, one or more other oil components, liquid at 20° C. and immiscible with water at 25° C., other than those previously listed, one or more emulsifiers, one or more zwitterionic, amphoteric, cationic or anionic surfactants, one or more other auxiliaries and/or additives, and one or more physiologically-active components, which compositions are useful in a cosmetic, personal hygiene and/or body-care preparation.
1. A wax-based composition comprising:
(a) from about 1% to about 20%, based on the weight of the composition, of one or more wax components selected from the group consisting of a C14-30 dialkyl carbonate, a C14-30 dialkylene carbonate, and mixtures thereof, having a melting point or mixture melting point greater than about 25° C.; and
(b) up to about 10%, by weight, of water,
wherein said composition is wax-based, with a melting point of the composition of above 25° C.
2. The wax-based composition of claim 1 further comprising one or more wax or oil components selected from the group consisting of a dialkyl ether, a dialkylene ether, a dicarboxylic acid, an hydroxyfatty alcohol, and mixtures of two or more thereof.
3. The wax-based composition of claim 1 further comprising a wax-like lipid component other than a wax component of claim 1 or a wax or an oil component selected from the group consisting of a dialkyl ether, a dialkylene ether, a dicarboxylic acid, and an hydroxyfatty alcohol.
4. The wax-based composition of claim 1 , wherein component (a) is present in about 1% to about 10%, based on the weight of the composition.
5. The wax-based composition of claim 1 wherein component (a) comprises saturated unbranched C16-22 dialkyl carbonates.
6. The wax-based composition of claim 5 wherein component (a) comprises distearyl carbonate.
