Description
Nicotinic acid (CAS 59-67-6) is a water-soluble B-vitamin also known by trade names Niacin, Niac, Tinic, Nicyl, Efacin, and Efacin. It carries no assigned E-code but is recognised under EC number 200-441-0 with molecular formula C6H5NO2. It belongs to the B3 vitamin group alongside nicotinamide.
In personal care formulations, nicotinic acid acts as a skin conditioner by supporting cellular NAD+ synthesis, improving barrier function at concentrations typically between 2–5%. In food manufacturing it functions as a flavorant and nutritional fortifier, while in chemical synthesis it serves as a catalyst or reaction intermediate in pyridine-derivative production.
Nicotinic acid is available in pharmaceutical grade (Ph.Eur., USP) and food grade (FCC) specifications, with REACH compliance confirmed for EU supply. It is supplied as a white powder under HS code 29362990, typically in 25 kg bags or fibre drums.
