Prashy123 said:…Oxothiazolidinecarboxylic Acid 2%…Ah, an interesting ingredient! I’m familiar with N-acetyl-thiazolidine-4-carboxylic acid aka N-ATCA or folcisteine, which is used as plant growth regulator.Like N-acetylcysteine ethyl ester aka NACET and N-ATCA, OTCA is one of the more stable cysteine derivatives and used to increase intracellular glutathione. I’m still a bit sceptical since N-ATCA is not just metabolised to cysteine by mitochondria but also to formaldehyde. OTCA on the other hand is said to decarboxylate spontaneously after a first metabolic activation step by 5-oxoprolinase and has been proposed for infusion solutions (dunno if it’s actually put to real use).Anyway, quite stable molecules and one of the least in your product to cause any issues
. Just focus on the others.
