Stearic Acid and Saponification.
Dear All,
If I want to use Stearic Acid as an emollient and thickener in my cream. Do I need to saponify them or not?
Thank in advance for every comments.

If you are making a traditional type vanishing cream, then yes. The stearic acid is partially neutralised.

Generally, no.

No, you don’t “need” to. It has an influence on your end product though since “X”-stearate and stearic acid are two different chemical compunds. Also what you neutralize it with has an impact. To my knowledge partially neutralised is most common in a cream. Best is to make a couple of experiments…

I have been advised by several cosmetic chemists that using TEA with Stearic Acid with the rate of one part TEA to two parts Stearic will be enough to “saponify” part of the Stearic Acid with the TEA but leave some Stearic Acid left over to add to the “creaminess” of the product.
