Cosmetics Formulation Development

Please give advice, I use Soy Lecithin mixed with Tween 20 HLB can be adjusted around 6-7 but the formula Unstable, please suggest Emulsifier to add. The product is a face serum.

Hello, the reason for choosing Soy Lecithin is an enulsifier, why? Want to emphasize naturalness? If so, use LeciCream™ (Natural Emulsifier / Cream Maker)

thank you very much Chosen because it is a natural ingredient as well. I don't know LeciCream When heated, will it have a strong smell and what is the HLB value? Use it instead of Soy Lecithin in the same proportion as it used to be? and if used as Emulsifier in general, such as Span80, what are the disadvantages or if I use Soy Lecithin but add ClayThick™ ( Magnesium Aluminum Silicate , Ultra Hydrate) added, will it help stabilize the layers?

Hello

Unknown LeciCream when heated. Will there be a strong smell?

No strong smell. Recommended use rate 3-4%. Emulsifier in general, such as Span80, what are the disadvantages or if I use Soy Lecithin but add ClayThick™ ( Magnesium Aluminum Silicate , Ultra Hydrate) is unstable, can you test it?
