Abstract

A germicidal detergent composition comprises a water-soluble non-soap synthetic organic non-ionic or ampholytic biodegradable detergent and a germicidally-effective concentration, preferably 0.01-5% by weight of the composition, of tyrothricin, bacitracin, polymyxin or neomycin or an organic or inorganic salt thereof, but does not contain a steroid or a mineral oil. The detergent may be non-ionic, for example (1) a mono-, oligo- or poly-saccharide ester of one of the following:- hydroxy fatty acids or fatty acids, aromatic carboxylic acids or halo, nitro, hydroxy, amino or methoxy derivatives thereof or sulphonates of the foregoing, aromatic aldehydes or ring substituted methyl, halo nitro, amino, hydroxy or methoxy derivatives thereof, aromatic ketones <FORM:1063787/C4-C5/1> where R is an aryl nucleus, R1 is alkyl, aryl, aralkyl, alkaryl or cycloalkyl; or (2) a compound of one of the formulae <FORM:1063787/C4-C5/2> where R is alkyl, n is 15-18, <FORM:1063787/C4-C5/3> where R is alkyl or <FORM:1063787/C4-C5/4> where R is alkyl; or (3) a urea complex of polyethylene glycol esters of mixed fatty and resin acids. Alternatively it may be ampholytic, for example a compound of one of the formulae RNHCH2CH2COOH where R is alkyl, or a salt thereof, R(CH2COOH)NCH2CH2N-(CH2COOH)R where R is alkyl, or a salt thereof, RN(CH2COOH)2 where R is alkyl, or a salt thereof, or RNHCH2CH2NHCH2CH2COOH where R is alkyl, or a salt thereof, in all cases where R is alkyl, C10-C18 alkyl being preferred. The composition may also contain alkali carbonates, silicates, phosphates or borates, sodium sulphate or sodium chloride, bentonite, polyethylene glycol, sodium carboxymethylcellulose, methyl cellulose, propylene glycol, hydroxy ethyl cellulose, solvents such as pine oil, and polyphosphates, hexametaphosphates or sodium salts of polyaminocarboxylic acids, and may be in the form of a cake, a bar, powder, chips, granules, flakes, a lotion, a liquid or an aerosol.ALSO:A germicidal detergent composition comprises a water-soluble non-soap synthetic organic non-ionic or ampholytic biodegradable detergent and a germicidally-effective concentration, preferably 0.01-5% by weight of the composition, of tyrothricin, bacitracin, polymyxin or neomycin or an organic or inorganic salt thereof, but does not contain a steroid or a mineral oil. Numerous detergents are listed. In examples the antiobiotic is in the form of the base material, its sulphate or its palmitate, the composition being in liquid (e.g. skin lotion, shampoo) or bar form. The composition may also contain builders such as alkali carbonates, silicates, phosphates or borates; sodium sulphate or chloride; colloidal materials such as bentonite, sodium carboxymethylcellulose or hydroxyethyl cellulose; solvents such as pine oil; and sequestering agents such as polyphosphates, hexametaphosphates or sodium salts of polyamino carboxylic acids.
