3-O-Ethyl-L-ascorbic acid is suitable for whitening and freckle removal products, wrinkle removal and anti-aging products. 3-O-Ethyl-L-ascorbic acid is a very useful vitamin C derivative, which is not only very stable in chemicals, is a discoloring vitamin C derivative, but also an lipophilic and hydrophilic amphoteric substance, which greatly expands his scope of application, especially in daily chemistry. 3-O-Ethyl-L-ascorbic acid is easy to enter the dermis layer through the stratum corneum, and it is very easy to decompose by biological enzymes in the body after entering the body, thus exerting the biological effect of vitamin C.

Chemical Profile: A white to off-white crystalline powder with the formula C₈H₁₄O₆, soluble in both water and ethanol (broader solubility than pure vitamin C).
Stability Advantage: Resists oxidation under light, heat, and alkaline conditions—overcoming the instability of native L-ascorbic acid, which degrades easily in formulations.
Synthesis Route: Commercially produced via the ethylation of the 3-hydroxyl group of L-ascorbic acid, ensuring high purity (typically ≥98%) for industrial use.
Acts as a pro-vitamin C: Once absorbed, it hydrolyzes to release active L-ascorbic acid in biological systems.
Inhibits tyrosinase activity (similar to arbutin) and promotes collagen synthesis via its reducing properties.
Cosmetic Chemistry: The primary application, used in whitening creams, serums, and anti-aging products (formulated at 1–5% concentrations). It integrates well with other actives like niacinamide, peptides, and hyaluronic acid.
Personal Care Formulations: Added to sunscreens, toners, and masks for its antioxidant and skin-brightening effects, suitable for sensitive skin due to low irritation.
Potential Pharmaceutical Use: Investigated as a stable vitamin C supplement ingredient and topical agent for skin condition management, leveraging its bioavailability.
Quality Standards: Complies with global cosmetic regulations (FDA, EU EC 1223/2009) with strict limits on heavy metals (≤10 ppm) and impurities.
Storage Requirements: Packaged in airtight, light-resistant containers (aluminum foil or HDPE) and stored at 15–25°C in dry conditions, with a shelf life of 24–36 months.
Safety Profile: Low toxicity (LD₅₀ > 2000 mg/kg, oral rat) with minimal skin/eye irritation; industrial handling requires standard PPE (gloves, dust masks) to avoid inhalation of fine powder.
