dimethicone in water
Hi all,
I am new to cosmetic science and eager to learn more.
I have a quick question, dimethicone is not soluble in water at 1% as I can see a thin layer of oil on top of water layer and I am trying to solubilize it by adding 1% tween 80 with a vigorous mix at 40C. However it doesnt seem to work as there are still two layers and the solution looks more cloudy.
I know its a simple question to most of you but Could someone please explain?
thank you ! -

You’re not going to succeed going that route. Instead, use a water-dispersible silicone, e.g. Silsense DW-18.

You can also use DC 193 Fluid from Dow Corning inci peg 12 Dimethicone which is water soluble and surface active
-
should it be premixed 1% of dimethicone in 2% of tween 80 then only added into the water?
-
yes-an emulsifiable concentrate is always better but you may need higher ratio of P_80-
-
DrBOB- thank you ! what ration of P_80 that you are suggesting?
-
Are you sure that dimethicones are soluble/dispersible in polysorbates?
-
not sure which is why suggested using silicone copolyol whih is water soluble.What do you think?
-
I tried 2:1 ratio of tween 80:dimethicone- I premixed 1% of dimethicone in 2% of tween 80 at 45C and then added into water but didnt work- Maybe I am better off going with water soluble silicone. thank you all !

Oppss…i knew it. Tween 20 can only solubilize oil in water but not silicone. My mistake, sorry about it.
