Abstract
A composition, eg a water-based polymer emulsion, cosmetics and the like, is preserved against microorganism growth, by incorporation of from 5-1000 ppm of an inorganic biocidal component which comprises a sparingly soluble silver compound deposited on a synthetic oxidic support.
Claims15
A concentrate biocidal composition comprising a synergistic combination of (i) 1-15 wt. % of a biocidal silver compound deposited on a synthetic oxide support and (ii) about 15 wt. % of sodium dioctyl sulphosuccinate, the balance of said composition consisting essentially of water.
A biocidal composition comprising a synergistic combination of (i) a biocidal silver compound deposited on a synthetic oxide support at a loading of 1 to 75% by weight of the support and (ii) a sulphosuccinate.
A concentrate biocidal formulation comprising a synergistic combination of (i) a biocidal component and (ii) a sulphosuccinate compound, in water, wherein the biocidal component is a silver compound having a solubility of up to and including 11.11 grams per liter deposited on a synthetic oxide support at a loading of 1 to 75% by weight of the support.
