Currently building a new 'natural' shampoo formula for a customer and having a very weird problem. Shampoo gets slowly separating on the top after 1 day! I tried different mixing methods and all comes down to separation after 1 day or few weeks. Maybe some of you have an idea why does it happen? Could it be because of cationic guar quality?
I tried mixing it in few ways but result is always the same, formula can get stable for few weeks and then small amount of oils appear on the top. I have no idea why, maybe I missed something you can spot right away.
Coco glucoside 15%
Lauryl glucoside 10%
Cationic guar 0.5%
Non-ionic guar 0.5%
Glycerin 1% (dissolving guar in it)
Caprylic/Capric triglyceridies 0.75%
EO blend 0.3%
Citric Acid q,s,
Claim ingredients <1% (oils, herbs etc.)
Thanks for help
