Is there any negative effect from using cationic polymers in dishwashing liquids?
In a hand dishwashing liquid with 17% active surfactants, if we add 0.1-0.2% cationic guar or pq10, will it deposit on dishes and palates?
If it does deposit, then is there any negative effect from those polymers if we cook, eat and drink on those dishes?

@Abdullah The question would be why do you need to add them. If it’s for softness (on hands I believe), there are other ingredients. If it’s for foaming or detergency, there are other more suitable polymers as well that do nos deposit as much.

The main purpose is to make the dishwasher milder for hands.
Without a deposition aid, will there be any benefit of using other ingredients for hand softness?

@Abdullah If you want a milder dishwasher for hands, then play around with your surfactant system.
If you want hands to feel softer, you could try using Sodium cocoyl glutamate or PEG-7 glyceryl cocoate. You could try using a cationic polymer, of course…it just wouldn’t be my choice (I don’t recall any big brand doing it, but I might be wrong).

I use SLES: CAPB 3:1 but as total surfactant is high, i want it to be a bit milder.
Would PEG-7 glyceryl cocoate without a deposition aid do any benefit?
