3-o-ETHYL ASCORBIC ACID

Product Description

White to off-white powder, purity: ≥99% uses: As a raw material for cosmetics, it has the functions of whitening, antioxidation and anti-inflammation. The main markets are Japan, South Korea, Europe, America, India, etc. Dosage:0.5-15%，It is a stable and effective amphiphilic (hydrophilic and lipophilic) vitamin C derivative, easily soluble in water, structurally stable and not prone to discoloration. It can inhibit the activity of tyrosinase and prevent the synthesis of melanin. Accelerate the synthesis of collagen and improve skin luster; Eliminate free radicals in the body; Anti-skin inflammation and inhibition of bacteria. Therefore, 3-o-ETHYL ASCORBIC ACID has the functions of whitening, antioxidation and anti-inflammation.

Inhibit the activity of tyrosinase, suppress the formation of melanin, restore melanin to colorless, effectively remove spots and whiten the skin, improve dull and lackluster skin, and endow the skin with elasticity.

It has an outstanding antioxidant effect in cosmetics, ensuring the utilization of vitamin C. Compared with the original vitamin C, vitamin C ethyl ether is very stable and not prone to discoloration.

It has a powerful antibacterial and anti-inflammatory effect, and can resist inflammation caused by light.

After entering the dermis, 4-dimensional C-ethyl ether directly participates in the synthesis of collagen to repair the activity of skin cells, increase collagen, and thus make the skin plump and elastic, as well as smooth and delicate.

It has both lipophilic and hydrophilic structures, which are easily absorbed by the skin and can reach the dermis directly.

It has good stability and is resistant to light, heat, acid, alkali, salt and air oxidation.

Whitening effect test

In addition, through our company’s internal zebrafish tests, it can be clearly seen that VCE has a good effect on the reduction of melanin

Comparison of stability tests

VCE has strong stability

Test object: 10% VCE aqueous solution

Test content: Placed at room temperature/windowsill light /45℃ oven

Test duration: May 16, 2023 – September 5, 2023 (> 3 months)

Test results: As shown in the following figure, a 10% VCE aqueous solution, without the need for any protective agent or pH adjustment, does not undergo any color change under high temperature or light conditions. In contrast, the aqueous solution of 10% of the original VC underwent a significant color change.

Several researchers from the University of London in the UK compared the permeability of VC ethyl ether on LabSkin models and human skin models. It was found that the EA permeability delivered through LabSkin within 24 hours was 55.1±1.8%. The penetration volume of human skin was similar, accounting for 58.0±4.2% of the applied dose (p>0.05).

It has a definite whitening and freckle-removing effect

In The article “The Anti-Ageing and Whitening Potential of a Cosmetic SerumContaining 3-O-ethyl-L-ascorbic Acid”, The depigmentation ability of the 30%VC ethyl ether and 1% lactic acid composition was specifically evaluated in the reconstructing Human pigment model (Reconstructed human Pigmented Epidermis (RHPE)). It was found that the melanin content in the control group was 20.0μg/mL, while that in the experimental group decreased to 16.60 μg/mL, a significant reduction of 17.10%.

Storage conditions: Store at room temperature and avoid direct sunlight. Seal the container in a dry and well-ventilated place. Shelf life: 2 years
