  • Viscosity building composition for personal care products
    Patent number: 10064809
    Abstract: A viscosity building composition is described. The viscosity building composition comprises a fatty alcohol in combination with one or more polyglyceryl esters. In one embodiment, the composition contains a fatty alcohol in combination with a polyglyceryl monoester. In an alternative embodiment, the composition contains a fatty alcohol combined with a polyglyceryl polyester, such as a polyglyceryl diester or a polyglyceryl triester. In still another embodiment, the composition comprises a fatty alcohol mixed with a blend of polyglyceryl esters. The blend may include at least one polyglyceryl monoester in combination with at least one polyglyceryl polyester, such as a diester, triester, tetraester or decaester. The polyglyceryl polyester is present generally in an amount greater than the monoester. In an alternative embodiment, the blend may include two or more polyglyceryl polyesters.
