Expert Verdict

High molecular weight limits dermal absorption; dimethicone is considered safe and non-irritating; standard PEG/PPG ethoxylation impurity considerations apply. A PEG/PPG-modified silicone (polyether-modified polysilsesquioxane hybrid); the methyl-ether capping on both PEG and PPG chains adjusts HLB and fluidity; provides lubricity, gloss, and defoaming
