Title: Detergent compositions
IPC: A01N59/12
Filed: 1951-05-08
Abstract: A germicidal detergent composition comprises a solution of iodine in a water-soluble, non-ionic surface-active agent having the formula R-(CHR1-CHR1-O)n-H, wherein R is the residue of a water-insoluble organic compound containing at least 6 carbon atoms and having an active H atom, R1 represents H or lower alkyl and n represents an integer from 3 to 100 or higher, especially 6 to 50.  The solution may contain up to 15 per cent. by weight of iodine, but from 1-3 per cent. is usually sufficient.  The polyalkenoxy groups of the solvent are preferably derived from ethylene oxide. but propylene and butylene oxides may also be employed.  R is preferably the residue of an alkyl phenol containing 6-18 alkyl carbon atoms, but it may also be derived from other organic hydroxy compounds, such as the alcohols derived from fatty acids, e.g. those given below, or alcohols obtained by hydrogenation of the fatty acids from animal or vegetable oils, e.g. castor oil.  R may also be derived from mercapto compounds such as dodecyl, oleyl, cetyl, decyl and benzyl mercaptans or thiophenols or thionaphthols; from amines such as octyl, cetyl, oleyl or naphthyl amines or alkyl anilines; from carboxylic acids, particularly fatty acids such as lauric, oleic, ricinoleic, palmitic and stearic acids and mixtures of acids obtained from animal and vegetable fats or by the oxidation of paraffin wax; and from sulphonic acids and the amides of carboxylic or sulphonic acids. U.S.A. Specifications 1,970,578, 2,002,613, 2,085,706, 2,205,021, 2,213,477 and 2,266,141 are referred to.ALSO:A germicidal detergent composition comprises a solution of iodine in a water-soluble, non-ionic surface-active agent having the formula R - (CHR1 - CHR1 - O)n - H, wherein R is the residue of a water-insoluble organic compound containing at least 6 carbon atoms and having an active H atom, R1 represents H or lower alkyl, and n represents an integer from 3 to 100 or higher, especially 6 to 50.  The solution may contain up to 15 per cent. by weight of iodine but from 1-3 per cent. is sufficient to give effective bactericidal action when the solutions are used at dilutions of 1 : 3,000.  The polyalkenoxy groups of the solvent are preferably derived from ethylene oxide, but propylene and butylene oxides may also be employed.  R is preferably the residue of an alkyl phenol containing 6-18 alkyl carbon atoms, but it may also be derived from other organic hydroxy compounds, such as the alcohols derived from fatty acids, e.g. those given below, or alcohols obtained by hydrogenation of the fatty acids from animal or vegetable oils and waxes such as cocoanut oil or castor oil.  R may also be derived from mercapto compounds such as dodecyl, oleyl, cetyl, decyl and benzyl mercaptans or thiophenols or thionaphthols; from amines such as octyl, cetyl, oleyl or naphthyl amines or alkyl anilines; from carboxylic acids, particularly fatty acids such as lauric, oleic, ricinoleic, palmitic and stearic acids and mixtures of acids obtained from animal and vegetable fats or by the oxidation of paraffin wax; from sulphonic acids and the amides of carboxylic or sulphonic acids.
