  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.

  The ratio provided for neutralization by Lubrizol states 0.9g/1g of carbomer IIRC. Optimization is the key to formulate successfully while keeping such data in mind.
