| Abstract: | The antifoaming effects of some polyoxyalkylene glycerol ethers (GPE) and their distearate (GPES-2) are studied. The best results are achieved by GPE with hydrophibic groups of mol. Wt. 3500-4000 and 10% hydrophilic group content and HLB 0.8-1.5.The antifoaming effects of GPES-2 is higher than those of GPE. GPES-2 with 15-20% hydrophilic group content results in the highest antifoaming effects. |
