I came across 2 suppliers with a very different pricing for CAPB 30%.
I notice that in their CoA, 1 supplier includes preservatives in their CAPB 30% and the other doesnt include any preservatives in the CAPB 30%.
Is it safe to purchase the one without preservatives ?
What is the preservatives function in CAPB 30% if it is said surfactant breakdowns protein of bacteria.
