I made a similar thickening system using modified cellulose plus SF-1. are you sure the precipitation is from acrylates. In my system, what I found is if the pH below 4.8 or maybe 4.7 the both gel-like and white particles will precipitate which I think should be from acrylates and cellulose. but if the pH is above 4.8 there will be some gel-like particles only in the system and I think it is from cellulose. and I further found if you add salicylic acid or lactic acid, these gel-like particles can’t be dissolved. but if you use citric acid the gel-like particles can be dissolved after stirring.

I made a formula similar. modified cellulose plus acrylates copolymer and when I add salicylic acid and lactic acid, some gel-like particles will come out. and I add citric acid, it also precipate but after 0.5-1h

stirring , all the particles can be dissovled.

I think it’s not about the viscosity. it’s about the ionic strength.

but is this a thickener ?

non-ionic thickener

what’s the full name☺

some customers said cationics are irritant to scalp especially the children.
