How do I know which chemical increases or decreases after increasing one thing in formula?
Hello @Perry and other professionals,
I am doing practice to make formulas after reading the book of @Perry
“How To KnockOff a Cosmetic
Formula”. Basically I have some questions.
how do I know how much percentage of each chemical I have to use after reading the ingredients from the product labels?
How do I know which chemical percentage increases or decreases after adding a new chemical in the formula? Like I am creating Vanishing Cream in which I added new chemicals(Borax) so I do not know how much percentage I have to add a new chemical and which chemical percentage will be decreased due to new chemicals. According to my knowledge, I was thinking to decrease water.
Kindly help me I am stuck on this point.
