Cl Clld 3/48 p jg a whole number from 1 to 5, in a soap bar is reduced by Field of Search including in the soap bar from 1 to 15% of free CH2 straight- 107; 424/172, 340 chain fatty acid.
• SOAP BAR This invention relates to antibacterial soap bars.
• X and X: are halogen
• X and X are hydrogen or halogen
• p is a whole number from I to 5.
• Preferred halogens are bromine and chlorine, in particular chlorine.
• a mixture of antibacterial compounds can be used, e.g., a mixture of compounds within the general formula or a mixture with other antibacterial compounds.
• the amount of antibacterial compound of the above general formula can be between 0.1 and 5 percent by weight of the bar, preferably between 0.1 and 2 percent.
• the total amount of antibacterial compound or compounds in the bar will normally be between 0.5 and 5 percent, preferably 0.5 to 2 percent, by weight of the bar.
• the invention therefore provides an antibacterial soap bar containing an antibacterial compound of the class herein defined and from I to 15 percent by weight of free fatty acid.
• the bar should preferably contain between 2 and I percent by weight of free fatty acid.
• the free fatty acid should be a C -C substantially straightchain fatty acid and can advantageously be such an acid as stearic acid or myristic acid or mixtures of acids derived from coconut oil, tallow fat or palm kernel oil. Such fatty acid is a usual superfatting agent.
• the antibacterial compound or compounds and the free fatty acid may be incorporated in any convenient manner either independently or together.
• the fatty acid can be released in the bar or soap from which the bar is made, for instance by the use of phosphoric acid as described in Netherlands application No. 6,709,575.
• the invention is particularly applicable to 4,2',4-trichloro- 2-hydroxydiphenylether where, in the general formula, X,, X and X, are chlorine, X is hydrogen, p is 2 and X is ortho.
• EXPERIMENT l Soap mushes containing I percent, by weight of soap base, of 4,2',4'-trichloro-2-hydroxydiphenyl ether were prepared in beakers.
• the soap mush was formed from 10 g. of a soap base and 50 g. of water.
• the soap base was prepared from an 80/15/5 tallow/coconut/sperm oil distillate fat charge.
• EXPERIMENT 5 Five sets of soap bars were prepared. All contained 1 percent of 4,2',4'-trichloro-2-hydroxydiphenylether. The five sets contained, respectively, 0.1 percent benzoic acid, 1 percent benzoic acid, 2.8 percent benzoic acid, 5 percent benzoic acid and 5 percent palm kernel acid, 2.8 percent benzoic acid is, on a molar basis, equivalent to 5 percent palm kernel acid.
• An antibacterial toilet soap bar consisting essentially of, by weight, between 0.1 and 5 percent of an antibacterial compound of the general fo rmula *arirntu
