ZINC-PYRIDINETHIONE SALTS, A PROCESS FOR MAKING THEREOF AND HAIR CARE COMPOSITIONS CONTAINING THEM |
摘要 |
Heavy metal salts of 1-hydroxy-2-pyridinethione in the form of crystals having defined shape and size, are useful in shampoos, creme rinses and other hair care compositions to deliver antidandruff benefits while not detracting as much as previous pyridinethione salts from the compositions' aesthetics. Hair care compositions containing such salts are also included. A process for producing heavy metal 1-hydroxy-2-pyridinethione salts comprises reacting a water soluble salt of the desired metal with 1-hydroxy-2-pyridinethione or with a water-soluble salt of the pyridinethione in an aqueous surfactant medium. |
