ODOR CONTROLLED PERSONAL CARE COMPOSITIONS CONTAINING HYDROXYPROPYL TRIALKYLAMMONIUM SALTS |
摘要 |
A personal care composition is provided which includes from 0.1 to 30% of a dihydroxypropyltri(C1-C3 alkyl) ammonium salt by weight of the composition; from 0.0001 to 0.005% of a tri(C1-C3 alkyl) amine or protonated form thereof by weight of the ammonium salt; from 0.002 to 15% of an aluminum salt by weight of the composition; and a cosmetically acceptable carrier wherein the composition has a pH ranging from 5.5 to 6.9. Unpleasant amine odor from trialkyl amines which arise from the dihydroxypropyltri(C1-C3 alkyl) ammonium salts is suppressed by the aluminum salt and by careful control of pH conditions. |
