Abstract
Many aqueous compositions containing a peroxygen compound have a very low viscosity and thus easily run off non-horizontal surfaces. Particularly, when the peroxygen compound is a soluble peracid, the compositions are difficult to thicken successfully, because many commonly available thickening systems for aqueous media either fail to thicken them or are decomposed and/or decompose the peroxygen compound substantially during storage. The compositions, preferably containing a soluble peracid, are thickened with an alkali metal silicate, preferably sodium silicate, such as Na.sub.2 O(SiO.sub.2).sub.2 used suitably in an amount of from about 2 to 6% of the composition and normally introduced in the form of a concentrated aqueous composition. The compositions may contain additionally an alkylammonium methosulphate. Preferred peracid solutions include dilute equilibrated peracetic acid solutions. The solutions when thickened to form a viscous liquid are suitable for disinfecting hard surfaces and when thickened to form a gel are suitable for suspension in an aqueous medium, for example in block form.
