Scrub Formulation Separating
I have a scrub formulation that seems to separate after sitting, but it is very inconsistent. I initially thought the problem was SLSA not fully dissolving, or too much shear for the Cocamidopropyl, but neither seem to be the case. Looking for pointer on what could cause, what I believe is the Cocamidoproply Betaine base on volume or liquid and consistency, to separate into a clear layer after packing. I am wondering if I need to ramp up the heat in Phase 2 even high than normal.
Phase 1 (Water, Polyq-7,Disodium ETDA)
Phase 2 (SLSA, Cocamidopropyl Betaine 30%)
Phase 3 (Crothix, Tocopherol)
Phase 4 (Butylene Glycol, Xantum) Gum)
Phase 5 (Exfoliants)

@Xenk more information would be needed to give you an intelligent answer here, i.e. exactly what is SLSA (acronym violation: arrrgghhh!); how much SLSA is involved here solid state, likewise the CAPB; which “exfoliant” is used and how much; does “xantum” = xanthan and which grade/how much was used - a critical element. I could go on….

I agree with @chemicalmatt. Also, it’d be useful to have more details on the process. For what I see, adding a gum after surfactants would not let if fully hydrate and properly interact with surfactants (I bet high mixing required to add the gum generated a lot of foam). I never had good experiences with xanthan gum in cleansing products (separation was always the issue).

It’s cosmetic grade soft but I have been testing new batches with 50% less gum and different primary anionics. It sounds like I was on the right track. I am not a fan of xanthan gum in general, but it’s much harder to get some of the alternatives in reliable supply here. Thanks for the tips.
