Storage requirements: Seal and store in a cool, dry, dark environment (15–25℃). Avoid high temperature, humidity, and direct sunlight. Shelf life is 2–3 years as a solid; stable in formulations with pH 3.0–7.0, no obvious decomposition within 12 months.
What is Ethyl Ascorbic Ether powder?
Ethyl Ascorbic Ether Powder (CAS 86404-04-8, ≥98% HPLC) is a high-stability cosmetic brightening active raw material. It inherits all skincare effects of vitamin C, and greatly improves stability and skin permeability. It can effectively brighten skin tone, fade pigmentation, resist oxidation and firm skin. With mild property and wide compatibility, it is widely used in high-end whitening, anti-aging and soothing repair skin care products.
Core Advantages
Superior Stability: Resists oxidation, heat, and light; no yellowing (unlike pure vitamin C).
Amphiphilic Solubility: Works in water/oil phases; easy to formulate into diverse textures.
High Bioavailability: Deep dermal delivery; 15× higher absorption than L-ascorbic acid.
Non-Irritating: Gentle for sensitive skin; lower pH irritation than pure vitamin C.
Cost-Effective: Long shelf life (24 months sealed); reduces formulation waste.

Ethyl Ascorbic Ether powder Application
Skin-lightening cosmetics:
Added to serums, creams, lotions, and spot-fading products, recommended concentration 2–5%.
Targets chloasma, freckles, post-inflammatory hyperpigmentation (PIH), and dull skin, with long-lasting brightening effects.
Anti-aging skincare products:
Combined with retinol, peptides, or hyaluronic acid in anti-aging creams/serums to enhance collagen synthesis and reduce photoaging signs.
Sunscreen & after-sun products:
Inhibits UV-induced melanin production, complementing sunscreen efficacy. Used in after-sun repair products to soothe oxidative damage.
Makeup bases & foundations:
Added as a brightening ingredient to makeup products, improving skin tone uniformity and achieving a natural "glowing skin" effect.
