I have formulated a sulfate and silicone free shampoo which has this 'gel like' sedimentation / separation. I am listing down the raw materials, please help!
Sodium cocoyl glycinate
Sodium cocoyl isethionate
Sodium methyl cocoyl taurate
w/s Kokum butter
Sodium benzoate+Potassium sorbate
Citric acid to pH 5.5
Process: In water I disperse GHTC and then add Sodium phytate. Separately, I mix Lamesoft PO 65, SCI and Cocoglucoside to solubilise it well, and add this to main vessel. Then I add the other ingredients one by one.
My initial suspects were SCI and Lamesoft PO 65. I tried taking trials excluding each one separately, the problem persisted. Then I started removing the surfactants one by one, problem still persists. After that, I removed the GHTC, preservative and w/s kokum butter one by one, still there is gel like sedimentation.
I really don't understand where I went wrong. Please help!!
