Zinc pyrithione and copper pyrithione are highly evaluated in the market as an antidandruff agent for shampoo, or an antifouling agent for ship bottom paint and fish-farming net, or an antibacterial / antifungal agent or preservative / mildewcide for industrial products and household articles. For enhancing the market value thereof, there has been a demand for a product that not only attains an increase in conventional antibacterial / antifungal effects but also exhibits novel bioactive effects and that achieves improvement with respect to problems and drawbacks relating to properties, such as solubility in seawater, and stability, such as thermal stability and weather resistance, of polymer materials. There is provided a novel pyrithione complex compound obtained by converting the conventional pyrithione metal salt to a complex compound with an oxide or hydroxide of metal such as zinc, copper or aluminum. As compared with the conventional pyrithione metal salt, this complex compound exhibits superior antibacterial / antifungal effects, newly realizes a hair-regrowing effect and successfully attains improvement with respect to the solubility in seawater and thermal stability / weather resistance of polymer materials.

Antimicrobial compositions based on the synergistic combination of 2-methyl-3-isothiazolone and selected commercial microbicides where the compositions are substantially free of halogenated 3-isothiazolone, are disclosed. Particularly preferred are combinations of 2-methyl-3-isothiazolone together with benzoic acid, citric acid, sorbic acid, 1,2-dibromo-2,4-dicyanobutane, 1,3-dimethylol-5,5-dimethylhydantoin, phenoxyethanol, benzyl alcohol, zinc pyrithione or climbazole, that provide enhanced microbicidal efficacy at a combined active ingredient level lower than that of the combined individual 3-isothiazolone and commercial microbicide effective use levels.

A kit for treatment of acne vulgaris, said formulation of the kit effectively inhibiting or killing Proprionibacterium without antibiotics. A preferred formulation alleviates the four pathogenic factors of acne.In a preferred method using the kit, a first skin-wash formulation comprising a higher zinc pyrithione concentration than the second leave-on formulation is applied to the affected area and subsequently washed off the skin with water. Then, a second leave-on formulation, preferably comprising a minimum of 0.25% zinc pyrithione with additional ingredients for eliminating or reducing other pathogenic factors of acne vulgaris, is applied to the skin.The kit includes a skin-wash component and a leave-on component comprising the acne treatment of the invention. Formulations are preferably applied as creams, lotions or emulsions.
