Ok, i will try and revert.

You should increase pva and ethanol %

my colleague used to increase TEA in order for Ph increase but it led to clumping in the 1 month 45 C stability oven. but i prefer the equal amount of TEA to Carbomer for normal neutralization and i tried it which passed 1 month 45 C stability without clumping. please give me your opinion.

Dears, thank you for replies. Actually yes it is an order for a private label. As for Anhydrous hair gel, what would be the perfect preservative?

dears, i want some help please. kindly advise a preservation method or a preservative ingredient to extend the shelf life of hair gel to 5 years instead of 3 years.
