Preferably, R is C 2 -C 10 alkyl and R 1 and R 2 are C 12 - C 24 alkyl, e.g. ethylene-di- (N-octadecyl-urethane) and hexamethylene-di-(O-dodecyl-urethane). Optional ingredients are (a) other foam inhibitors, e.g. C 20 -C 24 fatty acids and their alkali metal soaps, paraffins, triglycerides and trialkylmelamines, (b) chlorine bleaches, e.g. potassium dichloroisocyanurate and oxygen bleaches, e.g. perborates, percarbonates, perpyrophosphates, persilicates and urea perhydrate, (c) inorganic and organic builder salts, (d) enzymes, (e) germicides, (f) optical brightening agents and (g) other detergent additives. |
