Title: Antibacterial detergent compositions
IPC: C11D1/83
Filed: 1959-01-30
Abstract: A heavy duty detergent composition comprises by weight (a) 5-50% of water-soluble non-soap organic detergent other than a cationic detergent; (b) 10-80% of a water soluble polyphosphate; and (c) 3 : 5-dichlorsalicyl -31 : 41-dichloranilide in a minor amount sufficient to render fabric antibacterial when repeatedly washed with solutions of the composition.  Component (a) may be anionic, such as the sodium, potassium, ammonium, or alkanolamine organic sulphate or sulphonate detergents containing 12-26 carbon atoms or higher fatty acyl or alkyl derivatives of lower amino acids, and/or non-ionic, such as alkylene oxide condensates; several types of suitable detergents are specified but those preferred are sodium and potassium dodecylbenzene sulphonates, sodium tallow alcohol sulphate and nonylphenoxypolyethenoxyethanol.  Component (b) may be an alkali p metal, ammonium, or alkanolamine pyro-, hexameta-, tetra-, or tripoly-phosphate, sodium tripolyphosphate in an amount of 20-50% by weight being preferred in solid compositions and tetrapotassium pyrophosphate in liquids.  Components (a) and (b) are generally present in a weight ratio between 1 : 15 and 3 : 1, preferably 1 : 5 to 2 : 1, the total of (a) and (b) comprising at least 20% and preferably 30-90% by weight of the composition. Bactericide (c) is usually present in an amount by weight of 0.01-2%, preferably 0,01-0,5%.  From 0,05 to 2% by weight of a soil antiredeposition agent, such as polyvinyl alcohol, polyvinyl pyrrolidone, sodium cellulose sulphate, starch and protein derivatives, alkyl cellulose, dextrins and phytates, but especially sodium carboxymethylcellulose, is generally present. Alkali-metal or ammonium salts of sulphuric, phosphoric, silicic, carbonic, boric and hydrochloric acids, sodium xylene sulphonate, fatty acid alkanolamides, bentonite, perfume, colour, corrosion and tarnish inhibitors, fluorescent brighteners, thickeners, solvents, lubricants, foam enhancers and stabilizers, and waxes may also be incorporated.  Fabrics which are rendered bacteriostatic by washing with these compositions are cotton, wool, rayon, rubber, acetate rayon, nylon and blends of these materials, but residual activity is greatest with cellulose fibres.ALSO:A heavy duty detergent composition comprises by weight (a) 5-50% of water soluble non-soap organic detergent other than a cationic detergent; (b) 10-80% of a water soluble polyphosphate; and (c) 3:5-dichlorsalicyl-31:41-dichloranilide in a minor amount sufficient to render fabric antibacterial when repeatedly washed with solutions of the composition.
