Micellar Cleansing Water Thickeners and Glycolic Acid Stability

Regarding your questions about using thickeners in Micellar Cleansing Water and the stability of Glycolic Acid powder:

1. SugarThick™ in Micellar Cleansing Water: You are correct that the product description for SugarThick™ mentions its ability to reduce Critical Micelle Concentration (CMC), which helps reduce irritation from surfactants. However, based on our information, using SugarThick™ as a thickener in a Micellar Cleansing Water formula, such as one using MakeUp-Wash™, does not negatively impact the cleaning effectiveness or the ability of the micelles to capture dirt and makeup. You can use SugarThick™ to increase viscosity without reducing the product's cleaning performance.

2. EasyThick™ and CMC Reduction: EasyThick™ is primarily a thickener for formulas containing detergents like shampoos and liquid soaps. Based on the available product information, EasyThick™ does not have the special characteristic of reducing CMC like SugarThick™. The manufacturer does not claim this property for EasyThick™.

3. Glycolic Acid Powder Absorbing Moisture: If Glycolic Acid powder has absorbed moisture and turned into a liquid, the glycolic acid itself is still chemically the same and retains its intrinsic effectiveness. However, the absorbed water dilutes the powder, meaning the concentration of glycolic acid in the liquid form is lower than the original 100% powder. While you can still use it, you would need to use a larger amount of the liquid to achieve the same concentration of glycolic acid in your final formulation as you would with the pure powder. Since the amount of absorbed moisture is unknown, it is difficult to determine the exact concentration of the liquid, making it hard to calculate the precise amount needed to match the original powder's effectiveness.
