Need help thickening a body wash
hi im formulating a body wash for a client and im having trouble keeping a good viscosity with high fragrance load. Any tips for getting this thicker? I can switch out the thickeners if necessary. I would also like to reduce the acrylates copolymer or take it out completely if possible. I noticed that I cant add the polyquat in the beginning of processing because the incompatibility with the acrylate. I can rearrange processing etc. Im looking for it to be a thickness similar to the Isle of Paradise Body Cleanser. Any suggestions are appreciated
Phase A
water about 40%
propanediol 5%
acrylates copolymer (Carbopol SF2) 12% or 5%
Sodium cocoamphoacetate 3%
capryloyl/caproyl methyl glucamide 3%
CAPB (47% active matter)11%
I then neutralize this to pH7.5-8
Phase B1 premix then add
Fragrance 2%
CAPB 6%
Phase B2 premix then add
polyquat 10 0.5%
propanediol 5%
Phase B3
euxyl pe 9010 1%
opacifier 1%
Lower pH to 5.5

It might be a different acrylates copolymer.

If your formula has 10% propanediol, that might contribute not to build viscosity. Remove it completely, or keep it at claim level. Also, 2% of fragrance is too high amd can also have impair viscosity. Usualy 0.5-1.0% is enough. Lastly, the nature of your surfactants doesn’t contribute on building viscosity. You could add some anionic surfactant to take advantage of micellar transitions.

Thanks for you response! unfortunately the client wants 2% fragrance and its not negotiable. I will try to remove the propanediol or add some anionics

@ketchito is (again) on point there with DEL that propylene glycol/ADD anionic surfactant. That alone will boost viscosity and lessen the need for all that acrylic polymer. As for your Polyquat10 addition problem, disperse it into water directly 100%, then add the alkali needed to neutralize the acrylic copolymer to that mixture. Slowly add the acrylic as drop-in thickener and it will neutralize while addition goes on thereby not complexing with polyquat-10. Also, you might consider polyquat-7 or another cationic polymer with lower mass-charge.
