Thank you ..
I have questions Sir @Perry , (I hope you dont mind)
8weeks(@45C) = 1 year, meaning, I need to store my sample in the oven for 6months to prove that the product has 3 years shelf life?

How to establish tolerance of the parameters (pH, viscosity)? do we have standards or is this from company’s decision?

Thank You Again Sir.

So 1.5% Salicylic acid is considered as drugs.. ( but based on cosmetic directive 2% is the limit )

I cant use menthol in toner? ( but i love the after feel )
I’ll lower the ethanol to 20%
