Retinyl palmitate[2]
Overview
Retinyl palmitate is a synthetic derivative of vitamin A, combining retinol with palmitic acid to enhance stability and bioavailability. It is widely utilized in cosmetic formulations for its ability to stimulate collagen production and improve skin texture. Industrially, it serves as a key ingredient in anti-aging serums, sunscreens, and dietary supplements. As a lipid-soluble compound, retinyl palmitate integrates seamlessly into oil-based formulations, offering prolonged shelf life compared to pure retinol. Its efficacy in reducing fine wrinkles and hyperpigmentation has made it a staple in dermatological and cosmetic R&D.
Physical and Chemical Properties
Retinyl palmitate exhibits a yellow hue and viscous consistency, transitioning between liquid and solid states near room temperature. Its molecular structure (C36H60O2) ensures compatibility with lipid matrices, while its ester linkage provides resistance to oxidation. Key metrics include a density of 0.92-0.95 g/cm³ and a low melting point (26-28°C), facilitating easy incorporation into emulsions. The compound’s insolubility in water necessitates oil-phase processing but enhances skin penetration in topical applications.
Main Applications
In cosmetics, retinyl palmitate is a cornerstone of anti-aging regimens, often found in night creams and serums at concentrations of 0.1-2%. Pharmaceutical applications include vitamin A deficiency treatments, where it serves as a stabilized oral supplement. The food industry employs it for fortifying dairy products and margarines, leveraging its fat solubility. Industrial buyers should note its dual role as an active ingredient and preservative enhancer in multipurpose formulations.
Safety and Storage
Retinyl palmitate requires protection from UV light and oxygen to prevent degradation into less effective compounds. Cold chain storage (2-8°C) in amber glass or aluminum containers is recommended for bulk quantities. Safety data sheets classify it as non-toxic at cosmetic doses but advise caution during handling to avoid eye/skin irritation. Regulatory compliance (e.g., FDA, EU CosIng) must be confirmed for target markets.
B2B Procurement Guide
Bulk purchasers should prioritize suppliers offering third-party purity verification (HPLC reports) and batch-specific Certificates of Analysis. Minimum order quantities (MOQs) typically start at 1kg for lab-grade and 25kg for industrial-grade material. Negotiate pricing tiers for larger volumes (>100kg), where prices may drop to approximately $150/kg. Audit suppliers for GMP compliance and inquire about custom stabilization solutions for specific formulations.
