Vitamin C
SINOBIO
29362700
Purity: 99% min
CAS No: 50-81-7
Molecular Weight: 176.12
Molecular Formula: C6H8O6
Appearance: White Crystal Powder
Structural Formula：
Ascorbic Acid Powder (also known as vitamin C powder) is a high-purity, multi-functional white to light yellow powder with antioxidant, skin-whitening, and collagen synthesis-promoting properties. It is widely used in nutritional supplements, skincare, and food preservation.
*Molecular Formula and Structure: The molecular formula of ascorbic acid is C₆H₈O₆, an organic compound containing an adjacent enol group (-C(OH)=C(OH)-C(=O)-). This structure confers strong reducing properties and acidity.
*Physical Properties: The pure form is a white crystalline powder, but due to its susceptibility to oxidation, the actual product may appear pale yellow. It is highly soluble in water, forming a weakly acidic solution with a pH typically ranging from 2.5 to 3.0.
*Stability: Ascorbic acid is sensitive to light, heat, and oxygen, and tends to decompose and lose efficacy. Therefore, the powder should be stored in a sealed, light-protected, and cool environment to extend its shelf life.
*Ascorbic acid is a powerful antioxidant that neutralizes free radicals and reduces oxidative stress on cells, thereby protecting the health of skin, blood vessels, and organs.
*In the food industry, it is used as an antioxidant to prevent browning of fruits and vegetables and extend shelf life.
*Brightening and Spot Reduction: Inhibits tyrosinase activity, reduces melanin production, and fades dark spots and acne scars.
*Anti-Aging: Promotes collagen synthesis, enhances skin elasticity, and reduces fine lines and wrinkles.
*Anti-Inflammatory and Repair: Relieves skin redness and sensitivity, and accelerates wound healing.
*Prevents and treats scurvy (caused by vitamin C deficiency).
*Boosts immunity, promotes iron absorption, and supports bone and dental health.
| Items | Specification |
| Characteristics | White or almost white,Crystalline powder or colourless crystals |
| Identification | Corresponds |
| Melting Point | 189°C ~ 193°C |
| PH (5%,W/V) | 2.1-2.6 |
| PH (2%,W/V) | 2.4-2.8 |
| Specific Optical Rotation | +20.5° ~ +21.5° |
| Apperance of Solution | Clarity: Clear; Colour: ≤BY7 |
| Residual solvents | Meets the requirements |
| Assay | 99.0%-100.5% |
*Usage: Can be used alone or mixed with other skincare products. It is recommended to start with a low concentration (such as 5%) and gradually build tolerance to avoid irritation.
*Suitable Scenarios: Primarily for nighttime skincare; daytime use should be combined with sunscreen. Can be applied locally to dark spots or used on the entire face to brighten skin tone.
*Recommended Dosage: 75–90 mg daily for adults, with a maximum tolerable dose of 2,000 mg per day. Adjust according to individual circumstances to avoid overdose.
*Administration method: Dissolve in water or juice for oral consumption, or take with food to reduce gastrointestinal discomfort.
*Used as an antioxidant and preservative to prevent oxidation and spoilage of fruits, vegetables, meat, and other foods.
*Used as a nutritional fortifier added to beverages, bread, and other foods.
A: Nutritional supplements are recommended for daily intake, but for skincare use, the frequency should be adjusted according to skin tolerance. Initially, use 2-3 times a week and gradually increase.
A: No. The vitamin C in fruits and vegetables works synergistically with other nutrients, which is more beneficial to health. The powder is only used as a supplement.
A: L-ascorbic acid has higher activity but poorer stability; derivatives have better stability but must be converted into L-ascorbic acid to function, potentially resulting in weaker effects.
Standard package: 25kg/drum
