Natural Moisturizing Amino Acids contains Methyl Paraben (0.25%), Propyl Paraben (0.25%). FDA to use not more than 0.25% of each type of weight for Natural Moisturizing Amino Acids The usage rate is listed below: 0.5-5% (3-5% for skin and 0.5-1% for leave-on hair). If I use Natural Moisturizing Amino Acids 5% in formula 100g = In my formula will have Methyl Paraben , Propyl Paraben how many %? Let's calculate. I'm dizzy!!!

Hello, 0.25% (proportion of Paraben that the FDA determines to use in Natural Moisturizing Amino Acids ) in 5% (Usage Rate Natural Moisturizing Amino Acids in the formula) is equal to 0.25% x 5% = 0.0125%.
