NICOTINIC ACID ADENINE DINUCLEOTIDE PHOSPHATE.

Insufficient Data / SKIN CONDITIONING, SKIN PROTECTING

Nicotinic Acid Adenine Dinucleotide Phosphate (NADP) is a fundamental coenzyme crucial for cellular electron transfer and maintaining redox balance within biological systems. In the skin, this molecule supports robust epidermal barrier function and enhances hydration by stimulating key cellular processes, analogous to its precursor, niacinamide.

Barrier support Hydration Antioxidant Cell differentiation

Science

Mechanism of Action

NADP functions as an indispensable coenzyme in cellular metabolism, facilitating electron transfer reactions and regulating cellular redox homeostasis through its oxidized (NADP+) and reduced (NADPH) forms. Within the skin, it is integral to hydrogen transfer coenzymes and indirectly boosts protein synthesis (like keratin), stimulates ceramide production, and accelerates keratinocyte differentiation. These actions collectively lead to increased intracellular NADP levels, which significantly improves the epidermal barrier and elevates skin moisture content.

Stability

NADP demonstrates water solubility, with β-NADP dissolving at 50 mg/ml. Aqueous solutions are not recommended for storage beyond one day, though frozen aliquots can maintain stability for at least one year, provided repeated freeze-thaw cycles are meticulously avoided. Formulations incorporating NADP or its derivatives, especially in emulsified or transparent gel products, may encounter stability challenges. While the optimal pH for NADP's stability is not precisely defined, its precursor, niacinamide, is most stable between pH 5-7.

CIR Status
Not reviewed
Sensitization risk Unknown

Direct safety assessments by bodies such as CIR, SCCS, or FDA for Nicotinic Acid Adenine Dinucleotide Phosphate as a cosmetic ingredient are currently unavailable. However, its precursors, Niacinamide and Niacin, have been deemed safe for cosmetic use by the CIR Expert Panel, and Niacinamide is FDA GRAS listed as a food additive. For laboratory handling, NADP+ (sodium salt hydrate) is advised to be considered hazardous until further information is established.

Verdict

Insufficient Data

While Nicotinic Acid Adenine Dinucleotide Phosphate demonstrates a promising mechanistic role in enhancing skin barrier and hydration, comprehensive clinical efficacy and safety data for topical cosmetic application are currently insufficient for a definitive assessment.
