What is the difference between PEG 8-dimethicone, bis-PEG 8-dimethicone and bis-PEG 8/PEG 8-dimethicone?
Silicone compounds are becoming a more and more important class of compounds used in almost every type of personal care application. INCI names for compounds previously called dimethicone copolyol were changed to indicate the number of moles of ethylene oxide (PEG) and propylene oxide (PPG) present on the molecule, and more recently to differentiate terminal and comb polymers. Significantly, the INCI name does not disclose the values of “a, b, c, d or e,” which are crucial to functionality.
