Abstract

A wetting and detergent composition suitable for use in bleaching compositions comprises (a) at least 5% by weight of a water-soluble ionic organic surface-active agent, (b) di- or trichlorocyanuric acid, preferably the latter, or a mixture of both, and (c) as a stabilizer for (b), an olefin in which one of the carbon atoms of the double bond is tertiary in character. Component (a) may be soap, an alkylaryl sulphonate, an alkyl sulphate, a fatty acid monoglyceride sulphate, or sodium toluene, xylene or naphthalene sulphonate. Component (c) is generally present in an amount of 5-40% by weight of (b) and may be either an odourless olefin such as tetraisobutylene, propylene tetramer, or 5-butyl -4-nonene, or an odoriferous unsaturated terpene; of several suitable terpenes mentioned, limonene is preferred. Adjuvants such as sodium sulphate, bisulphate, chloride and silicate, alkali metal phosphates and polyphosphates, magnesium sulphate and silicate, calcium chloride, citric, tartaric and sulphamic acids, ethylenediamine tetracetic acid and its salts, bentonite, carboxymethyl cellulose, fatty amides and alkanolamides, optical brighteners, anti-tarnish agents, and rancidity retardants may also be incorporated. Such inert adjuvants are generally present in amounts 100-1000 times the weight of polychlorocyanuric acid present. The composition may be prepared by dispersing the olefin in gaseous or more preferably liquid form and then mixing the olefin in such form with a liquid, gaseous or solid carrier which may contain, or may be mixed with, the surface active agent, the polychlorocyanuric acid being added subsequently. Alternatively, the polychlorocyanuric acid-containing composition may be tumbled and sprayed with a liquid or liquefied olefin, or a slurry containing the olefin may be spray-dried and the polychlorocyanuric subsequently mixed in. The final composition is desirably packed in moisture-impermeable material, e.g. glass, metal, or metal foil.ALSO:A detergent composition comprises (a) at least 5% by weight of a water soluble ionic organic surface active agent, (b) di- or trichlorocyanuric acid, preferably the latter, or mixtures of both, and (c) as a stabilizer for (b), an olefin in which one of the carbon atoms of the double bond is tertiary in character.
