Facial wash separation
Hello every one, I have the following formula for acne facial wash
SLES. 8%
COCO betaine. 7%
Salicylic acid. 1
Propylene glycol. 2
Green tea extract 2%
Xanthan 0.5%
Pearlizing agent 3%
Dw. Up to 100%
Nacl. qsThe formula keeps separating with heavy mass on the top and small quantity of water at the bottom ,
So what is the wrong ? And how can I fix it ?
Another question ????
How to turn the wash to become transparent ?
It was obique even before the addition of pearlizer -

How are you mixing this?
I can’t see any reason why this would be separating unless you had salts in the water that don’t get on with your pearlising or gelling agent.
Is your pearliser a cold-process or hot-process, too? -
@Soona What’s your final pH? Betaines tend to behave like cationics at low pH (in the case of CAPB, it happens at a pH below 5.5). Since you hace Salicylic acid and no base to raise pH, I see that could be the reason.

I think 3% pearl agent is too high. That could lead to separation. Also, salicylic acid is only soluble in water up to 0.25% so that may be separating out also.

I do adjust the PH around 5.5 to 6 and my pearlizer is hot process I add it at the fina step , so what is the optimum amount of pearlizer that I could use ?
