  Ascorbic Acid vs L-Ascorbic Acid

  Posted by mixc on January 22, 2019 at 8:55 am

  I want to try formulating an L-Ascorbic Acid based Vitamin C Serum however almost all of the Chemical suppliers sell “Ascorbic Acid USP”. May I ask if this is somewhat different that “L-Ascorbic Acid USP” since they have the same CAS no. and etc.

  I’m just confused since I don’t know why anyone will produce d-Ascorbic Acid.

  Hope you guys would help me know if this “Ascorbic Acid USP” is good enough.

  Thanks!

  Not sure where you’re looking, but nobody is interested in buying d-ascorbic acidb(as far as I know). So the general ‘ascorbic acid’ refers to LAA.

  L-ascorbic acid is the true vitamin C. USP just refers to the United States Pharmacopoeia, the standard to which it is tested. Ascorbic acid, Ascorbic Acid USP, Ascorbic acid BP, L-Ascorbic acid (with or without BP/USP) is all the same thing.

  D-ascorbic acid is often sold as Erythorbic acid. It’s much cheaper and tends to used in foods as an antioxidant.
