Abstract: Undecylenic acid derivatives of the general formula <FORM:0981416/C2/1> in which R represents an hydrogen atom, an alkyl (1-4 C) group or a partial ether chain [(CH2)2O]xH in which x is an integer of 1-30, n is 1-4, and y is 0 or 1-30, and provided that (n + y) is at least 2 are used as the fungicidal or bacteriocidal ingredient with a non-toxic, non-irritant vehicle in a pharmaceutical and/or cosmetic composition.  Undecylenic mono-isopropanolamide and diethanolamide; the condensation products of undecylenic mono-ethanolamide and up to 4 mols. of ethylene oxide, and of undecylenic mono-isopropanolamide and up to 4 mols. of ethylene oxide are specified.  Complexes of the alkylol-amides with excess alkylolamines are also mentioned. The vehicles include water with emulsifiers, pulverulent solids such as talc or organic solvents such as alcohol, and waxes, oils and greases.ALSO:Cleansing compositions, including shampoos, detergent preparations and soaps such as tablet, liquid, and shaving creams contain one or more undecylenic acid derivatives of general formula <FORM:0981416/C4-C5/1> in which R represents a hydrogen atom, an alkyl group or a hydroxyl substituted alkyl (1-4 C) group, or a partial ether chain [(CH2)2O]xH in which x is an integer from 1-30, n is 1-4, y is 0 or 1-30; provided that (n+y) is at least 2, as a fungicidal and bacteriocidal agent, with a non-toxic, non-irritant vehicle.  Undecylenic mono-isopropanolamide and diethanolamide; the condensation products of undecylenic monoethanolamide and up to 4 moles of ethylene oxide, and of undecylenic mono-isopropanolamide and up to 4 moles of ethylene oxide are specified and the vehicle may be water with an emulsifier or dispersing agent such as water-soluble soaps, anionic sulphated or sulphonated detergents and water-soluble salts of N-acyl amino acids; organic solvents such as alcohols; pulverulent dusting powders; base materials of creams or lotions such as wax, oil or grease; or shampoo or detergent preparations. Complexes with the derivatives and excess alkylolamines have similar properties.  Examples describe the preparation of a shampoo with the condensation product of undecylenic monoethanolamide and ethylene oxide in an aqueous solution with triethanolamine lauryl sulphate.ALSO:Pharmaceutical and/or cosmetic compositions comprise one or more undecylenic acid derivatives of formula <FORM:0981416/A5-A6/1> (in which R represents a hydrogen atom, an alkyl group or a hydroxyl substituted alkyl (1-4 C) group, or a partial ether chain [(CH2)2O]xH, in which x is an integer 1-30, n is 1-4, and y is zero or an integer of 1-30, and provided n + y is at least 2), with a non-toxic non-irritant vehicle.  Undecylanic mono-iso-propanolamide and diethanolamide; the condensation products of undecylenic monoethanolamide and up to 4 moles of ethylene oxide, and of undecylenic mono-iso-propanolamide and up to 4 moles of ethylene oxide are specified and the vehicle may be water with an emulsifier or dispersing agent, such as water-soluble soaps, anionic sulphated or sulphonated detergents and water-soluble salts of N-acyl amino acids; organic solvents such as alcohols, pulverulent dusting powders, base materials of creams or lotions, wax, oil or grease, or shampoo or detergent preparations.  The products are active against fungi and bacteria.  Complexes may be formed with the derivatives and excess alkylolamines which have similar properties.  Examples describe the preparation of a foot-powder with talc and undecylenic mono-isopropanolamide, and a shampoo with the condensation product of undecylenic monoethanolamide and ethylene oxide in an aqueous solution with triethanolamine lauryl sulphate.
