Naphtha emulsion shoe cleaners which have no tendency to develop yellow spots or "patches" are made with Amino-methyl-propanediol. An emulsion-type cleaner is prepared as follows Water/100.0 cc Low-boiling naphtha/200.0 cc 2-Amino-2-methyl-1,3-propanediol/2.3 g High viscosity methyl cellulose/1.0 g Stearic acid/6.2 g
配制方法:
Disperse the methyl cellulose in the water and add the Aminomethyl-propanediol. Dissolve the stearic acid in the naphtha. Pour this solution into the methyl cellulose dispersion and agitate. Better mixing can, of course, be obtained with a homogenizer, particularly in larger batches.
