    I am trying to create a pressed eye shadow and blush formula without using Dimethicone. 

    Does anyone one know of a natural binder for pressed color products that does not contain Dimethicone?  

    I tried a product called Cosmosurf C-E100 that was recommended to me but when I pressed the shadows they were too loose to hold together.

    If your shadow does not hold together, that is a very strong indication that you either don’t have enough binder in your formula, or that you did a very poor job of pulverizing the binder into your powder, or both. It’s also possible that your psi for pressing is too low, or your dwell time is too short. Did you try different binder levels? Longer mixing times? Higher pressure or longer dwell time?

    Also, binder systems consist of several components, dry and oil-based. What are you using for a dry binder? If you post your formula, we can help further.

    Hi Bob,

    When I used Cosmosurf the formula was: 60% Mica Powder, 40% Mica Color, 6% Cosmosurf and 4% Zinc Stereate. I ground it in an Oster and pressed with a manual One Ton Arbor Press. Using a few drops of alcohol in the pan before pressing.

    Should I use Magnesium Stearate instead of Zinc?

    In a few weeks I will be getting an automatic powder press from Eugeng and I will be able to apply more consistent pressure. I want to get a good formula together before then so I don’t waste a lot of shadows practicing.

    Also, is there something better than an Oster for blending or it that best?

    Sorry, I used 30% Mica Pigment not 40%.
