Sodium chloride solution in shampoo
Hello. I am formulating a shampoo where I would need sodium chloride to thicken it. I’ve been using fine powdered sodium chloride but I’ve noticed some kind of settling at the bottom. I wanted to know if if a 0.9% saline solution will work to thicken without causing instability issues being it’s added water? Here’s my basic formula:
Chelator (aqua, sodium phytate, alcohol)—0.3%
Cocoamido. Betaine/glyceryl laurate—12%
Sodium methyl lauroyl taurate—7%
Disodium lauryl sulfosuccinate—2%
Cationic guar gum
Sodium chloride powder—qs
My pH is normally about 6.2 but I noticed it’s thicker at a ph of 5.3-5.9. Please help, any tips are worthy. Thanks for reading.
