Question

I want to make a product with 5% concentration of AHA.

If I need 100 grams of the final product, using 100% Glycolic Acid (AHA) powder, is it correct to use 5 grams of AHA powder mixed with 95 grams of water to make a total of 100 grams?

Thank you in advance.

Answer

Yes, your calculation is correct. To get a 5% concentration of AHA in 100g of product using 100% Glycolic Acid powder, you would mix 5g of the powder with 95g of water (or other base) to make a total of 100g.
