Dimethylmethoxy Chromanyl Palmitate (DCP)

Chemical Name : 7-Methoxy-2,2-dimethylchroman-6-yl palmitate
CAS No. : 1105025-85-1
Molecular Weight : 446.66 g/mol

Key Properties

• Appearance : White to off-white powder

• Melting Point : 42-44°C

• Solubility : Oil-soluble (must be added to the oil phase in formulations)

• UV Absorption : 284-290 nm (in acetonitrile)

• Purity : Typically ≥99%

Mechanism & Benefits

1. Tyrosinase Inhibition : Effectively suppresses both mushroom and human tyrosinase activity, reducing melanin production.

2. Superior Whitening : Shows stronger dose-dependent melanin-lightening effects compared to arbutin, kojic acid, and magnesium ascorbyl phosphate.

3. Non-Cytotoxic : Unlike hydroquinone, DCP exhibits no significant cytotoxicity at effective concentrations.

4. Photoprotection : Protects keratinocytes from UV-induced damage, enhancing skin resilience.

5. Stability : Remains stable in cosmetic formulations within pH 3.8-8.4 and under high-temperature processing.

Applications

• Recommended Dosage : 0.01-0.1% in whitening products (e.g., creams, serums).

• Formulation Example :

  • DCP (0.05%)

  • Emulsifiers (e.g., SSE20, polyglyceryl-2 dioleate)

  • Solvents (e.g., isopentyl glycol)

  • Additives (e.g., hyaluronic acid, tremella polysaccharides)   2 .

Safety & Efficacy

• Clinically proven for brightening and spot-reducing effects.

• Complies with cosmetic safety standards and is suitable for sensitive skin.
