CONSTITUTION: The colloid active synthetic detergent comprises 20-25 parts by weight of an alkanol amide which is a condensate of a coconut-based fatty acid (a saponification value of 271 and an acid value of 269) and an alkanolamine (HOCH2CH2NH2); 18-22 parts by weight of isooctylphenoxy polyoxyethoxy ethanol as a nonionic surfactant; 42-45 parts by weight of distilled water; 12-15 parts by weight of p-tert-octylphenoxy polyethoxy ethanol; and 1 part by weight of ethylene diamine tetraacetic acid. The colloid active synthetic detergent has a particle size of 10¬-5 to 10¬-7 cm and has a pH of 10-11.
