The proposed emulsion concentrate comprises an antioxidant, a non-ionogenic surface active agent and a solvent. The antioxidant chosen is at least one compound selected from the group which includes butyloxytoluene, butyloxyanizole, and 2,2,4 trimethyl-6-ethoxy-1,2 dihydrosilane. The non-ionogenic surface active agent used in the concentrate is a compound selected from the group which includes the esters of polyhydric alcohols and fatty acids and the ethanolamides of fatty acids. The polyhydric alcohol or fatty acid esters in the concentrate can be oxyethylated esters of polyethylene glycol or fatty acids, while the solvent used in the concentrate can be fat or oil. The proportions of the various components (parts by weight) are as follows: antioxodant 22-81, non-ionogenic surface active agent 7-45; fat or oil 10-50. The concentrate may in addition contain a quantity of monoethanolamine equal to 12-28 % by weight of the antioxidant. |
