I have been trawling through the forum but can't really seem to find a solution to my problem.
I have a natural sulfate free shampoo with quite alot of oils/butters that has never had any stability problems.
I have since added cationic guar and whilst all of my surfactants are non-ionic my shampoo keeps separating into two layers, white opaque on the top half and transparent yellow on the bottom half.
What is the reason this could be happening?
Thanks in advance
