Silicon Oils Emulsification
Does Anybody can explain if non-ionic emulsifiers like ceteareth-25 or Steareth-21 or Peg-100 Glyceryl stearate or even Cationic emulsifiers like cetrimonium Chloride also can emulsify Silicon oils like dimethicon or cyclopentasiloxane by its own in creams.

@Robert You just need to check Dow’s and Momentive’s silicone catalogs, and check the emulsified ones to see what systems they use.

The short answer here is: affirmative. All will emulsify dimethicone with limits on loading. Better if you can add a PEGylated dimethicone as co-emulsifier. Better yet use the BETAC instead of CETAC for best result. I’ve found the behenyl quat combined with SPDMA/Lactic acid works best for emulsifying silicone oils. An aside: unless it is already part of a silicone gum blend ingredient in the formula, I’ve never understood why anyone would add D4/D5 cyclomethicone alone into a cream or lotion for topical use, or a hair conditioner. It does not do anything but evaporate; why it’s called “volatile silicone.”

thank you for help, Regards Volatile oils use in creams I am using them to add slipp to hair conditioners besides they leave no residue on hair after application, I can consider them also as a solvent for other types of silicones
