The present invention relates to a solid concentrate composition comprising: (a) from 5% to 25% by weight of zinc pyrithione (ZPT); (b) from 8% to 85% by weight of at least one surfactant, preferably, wherein the solid concentrate composition has a penetration hardness of between 20 N and 50 N according to the test method as disclosed herein.

Solid concentrate compositions containing zinc pyrithione

The present invention relates to a bar soap composition that contains zinc pyrithione (ZPT) and a metal-pyridine oxide complex, preferably a zinc-pyridine oxide complex. The bar soap may be characterized by enhanced discoloration resistance, extended shelf life, and/or increased anti-microbial efficacy.

Bar soap compositions containing zinc pyrithione and a metal-pyridine oxide complex

The present invention relates to a personal cleansing composition with an antimicrobial effect. The personal cleansing composition is in the form of a bar soap and contains zinc pyrithione and a soap surfactant. When dispersed in an aqueous solution at 1 wt %, the personal cleansing composition of the present invention is characterized by a pH value ranging that is higher than about 9.6 and lower than about 10.3. The present invention also relates to a process for forming an antimicrobial bar soap as described hereinabove.

Personal cleansing compositions comprising zinc pyrithione

The present invention relates to an antimicrobial bar soap that contains zinc pyrithione and a metal-phosphonate complex and is characterized by enhanced discoloration resistance, extended shelf life and/or increased anti-microbial efficacy.

Razor comprising a molded shaving aid composition comprising a pyrithione source

A bar soap comprising a pyrithione source, a soap surfactant, and a pH adjusting agent selected from a group consisting of ammonia solution, triethanolamine, diethanolamine, monoethanolamine, potassium hydroxide, sodium hydroxide, soluble carbonate salts, and combinations thereof, wherein the bar soap attains a pH of greater than or equal to 10.7. A process of inhibiting the formation of a discoloration in a bar soap comprising pyrithione sources by adding pH adjusting agent to attain a pH of greater than or equal to 10.7. A process of inhibiting the formation of a discoloration in a bar soap caused by dissolved ferric ions and/or cupric ions and pyrithione sources in the bar, comprising the step of adding from about 0.3% to about 20% soluble carbonate salt during manufacturing of the bar soap.

Bar soap comprising pyrithione sources

Cleansing bar compositions having high water content comprise: (a) at least about 15%, by weight of the composition, of water; (b) from about 40% to about 84%, by weight of the composition, of soap; and (c) from about 1% to about 15%, by weight of the composition, of inorganic salt. The bar compositions further comprise a component selected from the group consisting of carbohydrate structurant, humectant, free fatty acid, synthetic surfactants, and mixtures thereof. The bar compositions preferably have a Water Activity ('Aw') of less than about 0.95, preferably less than about 0.90, and more preferably less than about 0.85. The bar compositions are preferably manufactured by a milling process.
