Need Help on formulating Clear Facial Cleanser with Dense Creamy Foam
Hi,
Need help with formulating clear facial wash with Dense and creamy final foam.
The client also ask about low PH Cleanser, So I can’t use myristic, lauric, or else.
Here’s my prototype:
- CABP 8 %, Decyl Glucoside 10%, Sodium Lauroyl Sarcosinate 5%, Sodium Cocoyl Glycinate 15 %. I use NaCl as thickener.
For this prototype the foam is rich but not dense and creamy enough, I add NaCl until 2%, but the viscosity is not increase. I also use Carbopol Aqua SF-1 polymer/Acrylates Copolymer as thickener, and No, it’s not getting better.
Please, I’m all ears with all suggestion. -

Replace Decyl glucoside with Sodium cocoyl isethionate, and you’ll have a creamier foam and more viscosity. Also, I think your Glycinate could thicken with a lower pH.

How low in pH are you targeting?
-
Close to 4.5 or 4.0. If you don’t see an increase in viscosity, then focus more on switching from Decyl glucoside to a more salt-responsive surfactante (like SCI or a sulfonate).

Glucoside based and other non-ionic surfactants do not thicken with salt. You’ll need something else like maybe a Cellulose thickener. If you have salt in your system a Carbomer thickener will not work either.

Try adding some Lauryl Glucoside and lower the amount of decyl glucoside you use or keep your formula but use a good grade of xanthan gum instead of salt. Here’s What I would try: Drop the decyl, lower the glycinate to ~ 13%, add some SLSA (~0.5-2%), maybe increase the CAPB if needed, and may add a little extra Lauryl if needed (~1-5%). Recalculate the ASM and adjust the formula to the desired ASM.
