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.
* As a powerful antioxidant, it neutralizes free radicals, protects cells from oxidative damage, and delays aging.
* In cosmetics, it can reduce the damage to the skin caused by environmental factors such as ultraviolet rays and pollution.
* Skin cells rely on Vitamin C to synthesize collagen, maintaining skin elasticity and firmness.
* Topical Vitamin C powder can improve wrinkles and fine lines, making the skin smoother.
* Promotes white blood cell production, enhances the function of the immune system, and helps the body fight infection.
* Converts non-heme iron from plant-based foods into a more easily absorbed form, preventing iron-deficiency anemia.
* Participates in collagen synthesis, accelerates wound healing, and reduces scar formation.
| Items | Specification |

* As a nutritional fortifier, added to fruit juices, beverages, candies, and dairy products to increase vitamin C content.
* Used as an antioxidant to prevent food oxidation and spoilage, extending shelf life.
* Added to face creams, serums, and masks to brighten skin tone, reduce blemishes, and improve skin texture.
* Powder form is more stable, retaining more active ingredients, and is more effective than some liquid or emulsion formulations.
* Used to treat or prevent vitamin C deficiency (such as scurvy).
* As an adjuvant, it enhances immunity and promotes wound healing.
* Used as a photographic developer, electroplating additive, and feed additive.
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.
