In the shampoo that I want to make, I want to use.
น้ำมันหอมระเหย instead of
น้ำหอม but I'm afraid that adding too much will cause problems with the formula. The formula I use is from Hong Huat which is considered a general formula. Contains Water 3000 N8000 1000 Cocamidopropil betain 100g COCAMIDE MEAPEARL SHINE CONCENTRATE Pearl Powder 100g Lamesoft 100g COCAMIDE DI
ethanol AMIDESUDS BOOSTER 100g don't know if to put
น้ำมันหอมระเหย in the formula, how much can I put in a formula? Is there a way to calculate the formula in percentage? I'll be able to try a larger amount. As for the shampoo, do you have any advice?
