Product Description

Vitamin C (CAS 50-81-7), also known as L-Ascorbic Acid, is a water-soluble vitamin and one of the most extensively researched micronutrients for its essential role in human health. As a potent antioxidant and free radical scavenger, vitamin C supports a wide range of physiological functions, including immune function, collagen synthesis, and vascular integrity.

Our vitamin C powder is available in 99% purity grade (HPLC-verified), manufactured in standard facilities with full batch traceability. As one of the most widely traded industrial ingredients globally, vitamin C is heavily used in dietary supplements, food fortification, skincare formulations, and as an antioxidant food additive.

Fortified beverages and juices
Functional foods
Bakery products
Food preservation systems (nano-encapsulated formulations demonstrate approximately 75% antimicrobial activity compared to conventional vitamin C).

Cosmetics & Personal Care
Vitamin C is a staple ingredient in premium skincare formulations for its antioxidant, collagen-stimulating, and skin-brightening properties .

Key Benefits:
Protects against free radicals from UV exposure and pollution
Stimulates collagen production, reducing wrinkles and fine lines
Reduces hyperpigmentation by inhibiting melanin production
Helps with inflammatory skin conditions

Common Formats:
Anti-aging serums and creams
Brightening treatments
Sun protection formulations (complements sunscreen)
Formulation Consideration: L-ascorbic acid is most stable at pH below 3.5. Vitamin C serums should be stored in cool, dark places to prevent degradation.
 

Animal Feed
Vitamin C is added to animal feedstock to enhance anti-stress ability. Studies show that supplementary vitamin C given to broiler chicks at 150 mg/kg of diet helps animals cope with multiple environmental stress factors.

Stability Considerations

Vitamin C is susceptible to degradation from heat, light, air, and incompatible ingredients :
Incompatibilities: Oxidizing agents, alkalies, iron, and copper 
Heat Sensitivity: Avoid prolonged exposure above 60°C
pH Stability: Optimal stability at low pH (< 3.5) for skincare applications 
Light Protection: Use opaque or amber packaging
Encapsulation: Advanced technologies like silica dioxide encapsulation demonstrate 11.4 times higher antioxidant activity at 50°C and 27.7 times higher under UV light compared to free vitamin C, effectively isolating the compound from water, oxygen, and other adverse factors.
