Butylene Glycol, dicaprylyl carbonate and silica

Anyone has experiences on Butylene Glycol, dicaprylyl carbonate and silica for facial cream formulation? 
My search told me:
Butylene glycol for decreasing viscosity.
dicaprylyl carbonate and silica: reducing grease and helping enhances the absorption of other ingredients.

Thank you so much for all inputs.


  • I worked with butylene glycol and I haven't noticed it decreasing viscosity. It's good and not expensive humectant. It is a glycol and decreases water activity which an additional benefit. I also find it less tacky than glycerin, so it is my humectant of choice for many o/w formulas.
    If you want something for decreasing viscosity (for formulas with polymeric emulsifiers) go for humectants that are high in electrolytes such as sodium PCA (it's a viscosity killer). But my problem is usually how not to decrease viscosity.
    Silica.. it's quite multipurpose. You can use it in a formula for oily skin indeed. Have a look at clinique's pep start moisturiser so see silica used for oil absorption. I mostly use it in foundations and concealers though.
    I haven't worked with dicaprylyl carbonate.
  • Thanks a lot @ngarayeva001
