L-Ascorbic Acid 2-Phosphate Trisodium, often referred to as AA2P, stands as a premier vitamin C derivative, celebrated for its remarkable stability and multifaceted efficacy. Unlike its more volatile counterpart, pure L-Ascorbic Acid, AA2P is inherently pH-stable and less susceptible to degradation when exposed to light, air, or heat, making it an ideal ingredient for a wide array of high-quality applications in both the cosmetic and scientific research fields.

This sophisticated compound, with the CAS Number 66170-10-3, typically appears as a fine white powder, ensuring ease of handling and formulation. Its inherent stability is a significant advantage, allowing for a longer shelf life in finished products and maintaining consistent potency over time. When applied topically or utilized in biological systems, AA2P gradually releases L-Ascorbic Acid, providing a sustained and effective delivery of vitamin C's benefits without the immediate oxidative challenges associated with the un-derivatized form.

In the realm of skincare, L-Ascorbic Acid 2-Phosphate Trisodium is a powerhouse ingredient. It is highly valued for its profound ability to stimulate collagen synthesis, which is crucial for maintaining skin elasticity, firmness, and a youthful appearance. Furthermore, its potent antioxidant properties actively neutralize free radicals and reactive oxygen species, offering robust protection against environmental damage and premature aging. Cosmetic formulations incorporating AA2P often yield visibly brighter skin, a more even tone, and a significant reduction in the appearance of dark spots and hyperpigmentation by inhibiting melanin production. Its anti-inflammatory characteristics also make it an excellent choice for soothing irritated skin and supporting healthy skin, particularly beneficial for acne-prone complexions.

Beyond cosmetics, L-Ascorbic Acid 2-Phosphate Trisodium plays a vital role in various research and cell culture applications. As a reliable reducing agent, it donates electrons to other molecules, undergoing oxidation itself, which is fundamental in studies involving oxidative stress on biological systems. It acts as a crucial cofactor for enzymes involved in critical cellular processes, including collagen synthesis. Notably, research indicates its capacity to maintain the differentiation potential in bone marrow-derived mesenchymal stem cells (MSCs), especially when combined with FGF-2. It also offers synergistic protection to human mesenchymal stem cells against oxidative stress when used alongside N-acetylcysteine, underscoring its importance in advanced biological studies.

The demand for high purity, cosmetic grade L-Ascorbic Acid 2-Phosphate Trisodium continues to grow, driven by its proven efficacy and superior stability. For those seeking this premium ingredient, it is essential to partner with a reputable manufacturer and supplier committed to stringent quality control and product integrity. Ensuring the product meets an assay specification of 99% purity or higher is paramount for maximizing its benefits in final formulations. Customers looking to buy or purchase this advanced vitamin C derivative should inquire about competitive price options and bulk availability to secure a consistent supply for their production needs. Investing in a high-quality source of L-Ascorbic Acid 2-Phosphate Trisodium ensures the optimal performance and reliability of your products.
