Dimethicone (silicon)
Can someone pls advise which type of Dimethicone (silicon) and those Crosspolymer type that suitable for every cosmetic/skincare products; as there were so many on the market and Im so confused. Also, how to dilute dimethicone 100cs or 350cs?
Is Cyclomethicone the same as Cyclopentasiloxane?
Thankyou in Advance -

cyclotrisiloxane (D3), cyclopentasiloxane (D5),cyclohexasiloxane (D6), and cycloheptasiloxane (D7) D=3-7 belong to cyclomethicone(withcyclical structure ).

Use 350 CST dimethicone for all-around use in skin care. 1000 CST can be better for detangling in hair-care, and is almost as easy to emulsify as 350. I never unerstood the need for 200.or lower. As for volatile silicone, all will dilute dimethicone easily. D4 works best in hair-care due to its higher volatility, and is lower priced generally. Most of the majors supply a D4/D5 blend for general use, and yes, they are all cyclomethicone, just different heterocycle ring sizes.

tsemhoi re your question on “crosspolymer”, if you’re a DIY crafter, you could try the EL61 or EL40 from lotioncrafter (or eg DC9045 etc if you can get hold of the Dow Corning range). They are well worth experimenting with - give a great skin feel and some viscosity. A good inclusion is sepigel 305 (thepersonalformulator) as they can be tricky to emulsify.
