Vitamin C 1 kg

Bulk Ascorbic Acid for Cosmetic, Food and Industrial Formulations

Vitamin C, chemically known as ascorbic acid, ranks among the most demanded antioxidants across global manufacturing sectors. The 1 kg package is designed for conveyor-scale production lines, cosmetic laboratories with steady order volumes, and small food processing facilities that need a reliable raw material supply without frequent reordering of small batches. This ingredient belongs to the Vitamins category, which gathers active additives used to protect and enhance finished products at various production stages.

The primary demand for ascorbic acid extends well beyond home-based cosmetic making. In the food industry, the substance acts as an antioxidant and preservative, preventing fat oxidation and discoloration in juices, canned goods, processed meat products and confectionery. In the cosmetic sector, vitamin C is valued for its ability to even out skin tone, stimulate collagen synthesis and neutralize free radicals, which is why it appears in serums, emulsions, toners and facial masks. In pharmaceutical manufacturing, this raw material is used to produce vitamin complexes and solutions. The compound is also applied in household chemistry as a component of descaling and rust removal products thanks to its reducing properties.

When working with pure ascorbic acid, it is important to account for its instability upon contact with air, light and elevated temperatures. In water-based cosmetic formulas, vitamin C should be introduced at the final stage, at a temperature not exceeding 40 degrees Celsius, to prevent degradation of the active compound. Typical dosage in finished products ranges from 5 to 20 grams per 100 grams of formula depending on the intended function and target concentration. To improve formula stability, manufacturers often combine vitamin C with oil-phase antioxidants such as Vitamin E Powder, which slows oxidation and extends shelf life. Ascorbic acid also pairs well with pantothenic acid, available as Vitamin B5, which enhances the moisturizing and restorative effect of skincare formulas. For cosmetics requiring a pronounced antioxidant profile, manufacturers frequently use Alpha-Tocopherol Acetate in liquid form, which is easier to dose in industrial recipes.

Vitamin C should be stored in a sealed container, in a dry, dark place, protected from moisture and direct sunlight, since improper storage causes rapid loss of activity. For manufacturers with high raw material turnover, the 1 kg package allows planning purchases months ahead and reducing logistics costs.
