  • Applications

    Niacinamide (CAS 98-92-0) is used across several industries: in cosmetics/personal care, it serves as a skin-barrier supporting active ingredient with anti-inflammatory properties that can improve skin tone; in pharmaceuticals and nutraceuticals, it is a vitamin B3 supplement commonly formulated for dietary use; in food processing, it is used as a water-soluble vitamin fortification ingredient to enrich foods; in agriculture/animal nutrition, it serves as a feed additive to support metabolic processes and growth.
