L-ascorbyl Palmitate
SINOBIO
29362700
L-Ascorbyl Palmitate (L-Ascorbyl Palmitate) is a fat-soluble vitamin C derivative produced by esterification of ascorbic acid (vitamin C) with palmitic acid, with the chemical formula C₂₂H₃₈O₇ and the CAS number of 137-66-6.The following is presented from the properties, functions, application and safety:
1. Physical Properties
Appearance: white to light yellow powder with a slight citrus odor.
Solubility: extremely difficult to dissolve in water, but soluble in ethanol, ether, animal and vegetable oils and other organic solvents.
Stability: Stable in concentrated or crystallized state, resistant to high temperature, light and moisture, better than water-soluble vitamin C.
2. Chemical structure
consists of the hydroxyl group of ascorbic acid and the carboxyl group of palmitic acid connected by ester bond to form a molecular structure with both hydrophilic and lipophilic properties.
Molecular weight: 414.53 g/mol, melting point: 107-117℃.
| Item | Standard | Result |
| Appearance | White or light yellow powder | Conforms |
| Assay | More than 95.00% | 98.19% |
| Whiteness | More than 68 | 89.8 |
| Specific Rotation | +21~+24° | +23° |
| Melting Range | 107.0-117.0ºC | 109.0-110.0ºC |
| Lossing on dry | ≤2.0% | 0.30% |
| Residue on ignition | ≤0.1% | 0.03% |
| Total heavy metal | ≤4mg/kg | <4 mg/kg |
| Pb | ≤2mg/kg | <2mg/kg |
| As | ≤3mg/kg | <3mg/kg |
*Antioxidant: Widely used in oil-containing food (such as instant noodles, edible oil, hydrogenated vegetable oil), dairy products, meat products, etc., the maximum use level is 0.2 g/kg.
*Color Protecting Agent: Prevent oxidative discoloration of food and maintain color stability.
*Nutritional fortifier: As a compound source of vitamin C, used in baby food, milk powder and food for special dietary use.
*Added to creams, lotions, serums and other skin care products to enhance the antioxidant effect and delay skin aging.
* Used as a stabilizer to prevent the oxidation and deterioration of the oil components in the formula.
*The U.S. Cosmetic Ingredient Evaluation Committee (CIR) has evaluated that it is safe to use in resident and rinse-off cosmetics at a concentration of no more than 2%.
*As a stabilizer for pharmaceutical ointment and capsule preparations to improve drug stability.
*Added to thermal paper to enhance the heat resistance and stability of the paper.
*Research shows that it has anti-tumor potential, which can inhibit DNA synthesis of cancer cells and decompose cell membrane phospholipids.
-As a highly efficient oxygen radical scavenger, it can inhibit the oxidative rancidity of fats and oils and extend the shelf life of food.
-In the presence of metal ions (e.g. Fe³⁺, Cu²⁺), it can eliminate oxidative damage through reduction reaction and protect cell membranes and biomolecules.
-Preserves all physiological activities of vitamin C, including promotion of collagen synthesis, enhancement of immunity, and participation in hydroxylation reaction.
-Every 500g of L-ascorbyl palmitate can provide about 212g of vitamin C, which can meet the needs of nutritional fortification.
-The molecule contains both hydrophilic groups (ascorbic acid part) and lipophilic groups (palmitic acid part), which can be used as surfactant to improve emulsification performance.
Packing: 25kg/drum. We provide customized package for different quantity.
Shipping: by express DHL,FEDEX,TNT......or as your requirement.
Payment: T/T,western union,moneygram or as your requirement.
