How load 3% Sodium Ascorbyl Phosphate in cream without losing viscosity
Hi guys, I need some help here. I want to develop a 3% Sodium Ascorbyl Phosphate cream-lotion type of moisturizer.
Below are the emulsifier and thickener dosage:
Potassium Cetyl Phosphate 2%,
Cetearyl Alcohol 2.5%,
Xanthan gum 0.15%
The moisturizer is a thick cream before adding in the 3% SAP. After adding in SAP, it loses viscosity and become flowable and watery.
Is there any way to incorporate high % SAP in cream without losing its viscosity?
I’ve tried increase the thickener and emulsifier dosage, but it end up the sensory is very heavy. My expectation is to formulate a light-weight cream type with high % of SAP.
