Formulations containing Silicone
Hello there,
Would you please help me with this?How lotion, moisturizer and shampoo formulators incorporate a given silicone that does not dissolve in either water or oil?
Thank you. -

For emulsions dimethicone is added to reduce soaping. You don’t need much and 1.5-2% shouldn’t cause issues if you add it to the oil phase (even when you use polar oils).
You can add silicone emulsifier such as ViscOptima SE by croda or Abil EM 90
to stabilise higher amount of silicone.For shampoos, watersoluble forms are usually used (Amodimenticone for example).

You can either
A. buy a premade, water-soluble silicone emulsion.
Those from DOW are great, but they usually only sell by 18 or 200 Kg drums.
You can buy small amodimethicone amounts from shops like

But I don’t know how this one works in skin products. It works great for hair products tough. (I’m not affiliated with makingcosmetics in any way).B. emulsify silicone yourself
For shampoos you can neutralize LABSA with TEA and use it to emulsify silicones, but that’s only suitable for shampoos, not for skincare.
Emulsiying silicones with nonionic emulsifiers is tricky.C. buy a water soluble modified silicone
Water soluble ones don’t work well for shampoos, but are probably OK for skincare. -
PEG-8 dimethicone works well in skincare but although it’s water soluble it’s a bad idea for shampoos: reduces viscosity and foam.
