  • Sunscreen composition with polyhydroxy quaternary ammonium salts
    Patent number: 8496916
    Abstract: A cosmetic composition is provided including a water-insoluble UV-A organic sunscreen agent having a max ranging from 330 to 380 nm, a UV-B organic sunscreen agent having a max ranging from 280 to 400 nm, and a photoprotective enhancing agent which is a polyhydroxy quaternary ammonium salt such as bis(dihydroxypropyl)dimethylammonium chloride, in a cosmetically acceptable carrier, and wherein the composition exhibits an SPF value which is 1 to 30 units higher than in the absence of the photoprotective enhancing agent.

  • Odor controlled personal care compositions containing hydroxypropyl trialkylammonium salts
    Patent number: 8277786
    Abstract: 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.
