The present invention is related to the field of liquid disinfectant formulas, specifically with obtaining disinfectant compositions applicable to hard and smooth surfaces, porous surfaces and for human use; particularly with disinfectant compositions that allow the surface or surfaces where it is applied, a disinfection with a prolonged effect, for periods greater than 24 hours. More particularly with the use of long-lasting disinfectant compounds, some of them approved by international agencies such as the EPA, and which are also approved by the FDA for cosmetic use due to their low or null toxicity. More particularly, the present invention relates to the formulation of said compositions.

This invention relates to a hair care composition more particularly to a wash-off composition, especially preferred being a shampoo or a conditioner, which provides the desired anti-dandruff efficacy with enhanced stability of the active materials on hair/scalp during use. This is achieved through a judicious combination of an organic UV filter, a zinc compound and selective anti-dandruff agent. The composition comprises 0.01 to 3% by weight zinc pyrithione, an organic UV filter and 0.1 to 5% by weight additional zinc compound. The weight ratio of zinc compound to zinc pyrithione is over 3:1.
