Product Introduction

Magnesium Vitamin C Phosphate, also known as VC-PMG, is a stable derivative of Vitamin C combined with magnesium and phosphate. It is often derived through the esterification of ascorbic acid with phosphoric acid, followed by neutralization with a magnesium source. This compound is used in the food and beverage industries, as well as in cosmetics, due to its antioxidant properties and ability to enhance collagen production. VC-PMG serves as an effective alternative to ascorbic acid because it is more stable and less prone to degradation when exposed to air and moisture.

Production Process

The production of Magnesium Vitamin C Phosphate involves several key steps. First, ascorbic acid undergoes esterification with phosphoric acid to form a phosphate ester of Vitamin C [1]. This intermediate product is then neutralized with a magnesium source, such as magnesium hydroxide or magnesium oxide, to create the final VC-PMG compound [2]. The resulting product is purified, dried, and milled to achieve the desired particle size. Quality control measures, including HPLC testing, are implemented throughout the production process to ensure the purity and stability of the final product.

Application Scenarios

Magnesium Vitamin C Phosphate is widely used in various applications. In the food and beverage industry, it can be added to nutritional supplements, fortified foods, and beverages to enhance their nutritional value and provide antioxidant benefits [3]. In cosmetics, VC-PMG is used in skin care products, such as lotions, creams, and serums, due to its ability to promote collagen synthesis and protect against UV damage [4]. Its stability and effectiveness make it a versatile ingredient in formulations where Vitamin C's benefits are desired without the drawbacks of its rapid degradation.

Packaging and Storage

Magnesium Vitamin C Phosphate is typically packaged in multi-layer kraft paper bags or fiber drums with inner polyethylene liners to protect it from moisture and light [5]. Standard packaging sizes are generally 25 kg per bag or drum. It should be stored in a cool, dry, and well-ventilated area, away from direct sunlight and incompatible substances [6]. Proper storage conditions help to maintain its stability and extend its shelf life, which is generally two years from the date of manufacture.
