Carbopol Aqua sf1 (acrylates copolymer) and polyquats
Hello,
i need your experience. In Haircleansing formulations with carbopol Aqua sf1 I have the problem that the hair feels not so soft and slippery after rinse out. What can be the reason? My feelings are , that the carbopol blocked the quats ( pq10 , hydropropyl guar, Amodimethicone) so the cationic charge is not so good.
There is no literature from lubrizol about this.Any experience?Many thanks -

You would need to post your Formula. I would wager that there are other raw materials in the Formula that contribute to these properties and it is less likely to be your rheology agent.

I can’t post my complete formula, but I try hundreds with the same results.
Anionics active around 12 ( iselux sfb, akypo foam lm25)
cocamidopropyl hydroxysultanine around 6%0,2 pq 10
0,2 hydroxypropyl guar
0,6 proteins
4 % microemulsion of Amodimethicone
6% carbopol Aqua sf1to try different ph 5,5 5,8 6,0
It feels great during washing . But there is to less deposit on the hair.

@Ahlmeyer What’s your manufacture method (order of addition, mixing speeds, times, etc.) matter when using polymers of different charge.
Also, have you tried a simple dimethicone fluid instead of that amodimethicone microemulsion? Maybe you’re looking for a sensorial that that microemulsion won’t give you.

Aqua SF-1 will not hold up with all the cationics. It will not allow coacervation of the PQ-10, which is the “deposit” you are seeking. I suspect HP guar is interfering there too. The problem using acrylate copolymers in conditioning shampoos is they act as anti-redeposition agents: not a good thing, right? They work great for suspension and viscosity build, but that is about it.
Why not get rid of SF-1 & guar and build viscosity the traditional way? Increase the PQ-10 to >0.50% while you are at it. DEL the amodimethicone & CETAC & Trideceth-12 blend too. That is designed solely for conditioning and styling products, not shampoos. -

The classic or “traditional” built cleanser system: anionic: amphoteric: builder (usualy alkanolamide) at a ratio of 4:2:1 solid state. E.g. SLES:CAPB:Cocamide MEA at 12:6:3 percent respectively.
