One of our best lines is sulphate-free shampoo. Unfortunately the cost of the thickener (Glucamate VLT) has gone through the roof and I use it at around 4%. I don't want to remove the original thickener entirely because it has great hand-feel and also improves preservation, but I am looking at using an alternative lower cost thickener so as to be able to reduce the VLT to say 1%.
Today I came across some PEG-150 Distearate so I bought some. Have any of you used this thickener and if so would you like to comment?
