L-Ascorbic Acid and is protein encapsulated????????? Any Input
Hello,I was hoping someone could help shed light on the below for me. I have a customer with a Vit C serum which they claimed was 10% Vit C. I had it tested only to find that 2.2% was actually in there. When I came forward with this information, the below response is what I received. Does this make sense to anyone? Any helpful comments are appreciated I have some thoughts but not sure if they are correct.“One form we use is 7% L-Ascorbic Acid and is protein encapsulated to help stabilize it and prevent oxidation, the second form is 3% pure L-Ascorbic Acid. What we found from the lab tests is that the protein encapsulated L-Ascorbic Acid will not show up on a test for L-Ascorbic Acid because it’s encapsulated in the protein. Our lab tests showed Vitamin C levels of 2.9%, so the samples we tested and the samples you had tested are only picking up the L-Ascorbic Acid not encapsulated in protein.”Also, isn’t there a test for encapsulated product?Thanks
