Soaping effect
Hi, we are formulating a premium moisturizer of which formula is almost finished, but there is only 1 outstanding issue:
- A heavy soaping effect -
As emulsifiers we are using: Brassicamidopropyl Dimethylamine and C10-18 Triglycerides.
Wax: Shea butter (5%)
Thickeners: Cetyl Alcohol (3%), Glyceryl Stearate (3%), Xanthan Gum (0.50%).
OIls (11%): Triheptanoin, Pentaerythrityl Tetra-di-t-butyl Hydroxyhydrocinnamate, C13-16 Isoparaffin (and) Heptyl Undecylenate, Stearyl Heptanoate (and) Stearyl Caprylate.
We are using lactic acid at 0.50% as pH adjuster.
We are very satisfied with the texture and viscosity of it and we do not want to sacrifice them in order to eliminate the soaping effect, which is pretty strong for now. We can not use any type of sillicone or dimethicone, and even though we had tried adding 1-2% of dimethicone the soapping effect remains, because unfortunately it is really strong .
Your suggestions will be very welcome.
*Please note that we follow a healthy formulation process and very strict guidelines, so harmful or dangerous ingredients either for people or enviroment are strictly forbidden. We are not closed to synthetic alternatives as long as they are not dangerous and/or hazardous.
Thanks and Regards.

Hello.Try to add a powder substance (for example: Starch, Sillica or Nylon-12) and/or increase the amount of oils in the formulation.
