Vitamin A Palmitate, also known as retinyl palmitate, comes as an ester formed by combining retinol (pure vitamin A) with palmitic acid. In oil form, this nutrient holds a transparent to yellowish appearance, with a characteristic oily texture that signals stability and practical use across food, feed, pharmaceuticals, and cosmetic industries. Its molecular formula is C36H60O2, with a molar mass of about 524.86 g/mol. This compound acts as a fat-soluble vitamin, meaning it dissolves well in lipids but not in water. The density of Vitamin A Palmitate Oil typically measures around 0.95-0.98 g/cm³ at 25°C. The chemical structure features a retinyl group (a derivative of vitamin A alcohol) attached by an ester bond to palmitic acid, creating stable, long-chain molecules suitable for industrial formulation and human metabolism. HS Code for Vitamin A Palmitate often appears as 293621, classified under provitamins and vitamins with their derivatives.
Commercial Vitamin A Palmitate oil stands out through its variety of forms. Producers manufacture it as a clear, yellowish liquid for straightforward blending into edible oils and creams, but it can also show up as solid flakes, white or off-white powder, and fine pearls (small spherical beads) for ease of storage and specific formulation demands. The choice between these presentations depends on the processing settings—liquid form fits direct enrichment of edible products, while dry forms, such as powder and flakes, enter premixes or dry blends. The substance resists degradation at room temperature in the absence of heat and light, but extended exposure to air, UV, or elevated temperatures causes breakdown and reduced potency. Solubility sits strong in fats and some organic solvents, yet water suspensions or solutions need emulsifiers.
Raw production of Vitamin A Palmitate draws from fish liver oil and plant-based beta-carotene, then synthesizes the final ester through chemical processes combining vitamin A alcohol with palmitic acid. The resulting oil is stable, with a refractive index around 1.480–1.500 and a melting point near 28–30°C for the pure solid. As a major chemically synthesized form of vitamin A used in food fortification, this molecule resists air oxidation better than pure retinol, so shelf-life stands longer. Its structure, built from a series of conjugated double bonds and fatty acid tails, ensures compatibility with lipid-based delivery systems. In industry settings, manufacturers choose ingredients free of heavy metals and manage process controls tightly, maintaining purity standards (often above 97% assay for the main component).
Every batch of Vitamin A Palmitate undergoes analytical checks on assay, density, specific rotation, heavy metals, acidity, and microbial contamination. For example, meeting a specification means reaching vitamin A activity not less than 1,700,000 IU per gram in oil preparations. Specification sheets include the allowable content of free retinol, acidity value, and solvent residues. Color consistency—pale yellow to yellowish—is tracked visually, and density at 20°C stays between 0.950–0.980 g/cm³. Shelf life sits at about two years if stored in tightly closed containers and protected from light, heat, and moisture. Regulatory acceptance in Europe, the US, and Asia follows guidelines for purity, including microbiological limits and the absence of harmful residual solvents.
Vitamin A Palmitate's main role remains vitamin fortification. You’ll find it in margarine, milk, infant formulas, dietary supplements, and topical cosmetics, acting as a stable source for vitamin A delivery. Absorption from the gastrointestinal tract follows digestion and hydrolysis to free retinol and palmitic acid. While critical for vision, immunity, and cellular growth, improper handling and over-dosage raise safety concerns. Acute or chronic surplus in humans may cause hypervitaminosis A, marked by liver toxicity, skin changes, and neurological symptoms. Product safety sheets warn that ingestion above recommended levels or inhalation of powders can be hazardous, calling for gloves, goggles, and masks during industrial handling. Regulatory agencies cap allowable concentrations in food and supplements, and workplace exposure controls minimize risks for handlers.
Pure Vitamin A Palmitate falls into the category of chemicals with health hazards when consumed or absorbed in large amounts. Classified under GHS (Globally Harmonized System) guidelines, the oil form may irritate eyes, and powder handling creates a risk of airborne dust. Spills or leaks in production areas need prompt cleaning to prevent environmental contamination or worker exposure. While not strongly aquatic toxic, release into natural water systems without proper treatment brings regulatory penalties. Waste disposal follows chemical product guidelines, sending expired or contaminated material for incineration or controlled landfill. Workers who frequently handle the solid or concentrated oil use protective clothing and ventilation.
The molecular structure of Vitamin A Palmitate shows a long, flexible hydrocarbon tail derived from palmitic acid, ending with a polyene chain of conjugated double bonds characteristic of the vitamin A retinol backbone. Its chemical formula C36H60O2 gives a deep hydrophobic character, so the compound does not mix with water but disperses in all common vegetable oils. Analysis by HPLC (High Performance Liquid Chromatography) confirms the principal peak. Melting point analysis identifies the pure crystalline form, with the oil form remaining liquid at room temperature due to impurities and solvent content.
Vitamin A Palmitate markets globally as both a food-grade and pharmaceutical-grade additive, reaching customers via direct shipment or through blending with vegetable oils, milk, or flour in fortified foods. Top suppliers operate ISO-certified facilities, guaranteeing traceability of raw materials from palm oil or other plant sources, as well as ensuring batch-to-batch consistency. Local governments require notification or registration of fortification programs, especially for dairy, cereal, and infant foods. Global trade uses HS Code 293621. Storage and shipping use tightly sealed containers, often under nitrogen or inert gas to protect against oxidation. Growing emphasis on food and drug safety drives continued investment in analytical testing and supply chain transparency, while demand among developing countries for fortified foods increases market scale.
