We switched the emulsifier from Ewax (which rubs in nicely, but doesn't do great with very thin lotions) to Glyceryl Stearate & PEG-100 Stearate (Lotioncrafter 165) which is better for thin lotions, but now we have a rub in problem; the formula turns white when rubbed in and takes 3x longer to disappear into the skin.
Glycolic Acid 5%
Sclerotium Gum 0.5%
Glyceryl Stearate PEG-100 Stearate
Simmondsia Chinensis (Jojoba) Seed Oil
Phenoxyethanol, Caprylyl Glycol, Sorbic Acid
Suspect it might be an interaction between the gum and the emulsifier? It's often used in AHA formulas that have no issues with rub-in (for example the one from Acne.org).
What do you think is causing it and how to prevent it?
