Thickening a high fragrance level, sulfate-free shower gel
I have been experimenting with a formulation of
Sodium Lauroyl Methyl Isethionate - 10% active matter
Sodium Methyl Cocoyl Taurate - 4.5% active matter
Cocamidopropyl Betaine - 7% active matter
DISODIUM COCOYL GLUTAMATE - 1.5% active matter
and this produces a very thick clear gel.
however when I add my perfume at a high level (2%) with PEG 40 HCO (4%) this completely lowers my viscosity.
I have tried some thickeners (crothix, kaopan TWIS3992) and none seem to rebuild the viscosity (which leads me to believe the fragrance is the issue). any ideas here how to keep the fragrance level & clarity to achieve aprox 6000cps? I would not like to use acrylate co polymer.
Formula does not thicken with additional salt and I discovered the best amount of CAPB was above by adding this last until maximum viscosity was achieved.
any help is much appreciated! thanks!
