What Is 3-O-Ethyl Ascorbic Acid Powder?
3-O-Ethyl Ascorbic Acid is a derivative of vitamin C with a stable structure. It overcomes Vitamin C’s disadvantage of easily discoloring and possesses both hydrophilic and lipophilic characteristics. It can penetrate the stratum corneum and gradually convert to active Vitamin C in the skin.
According to multiple studies, 3-O-Ethyl Ascorbic Acid can help inhibit tyrosinase activity, reduce melanin synthesis, improve skin radiance and elasticity, and protect skin from oxidative stress. Therefore, 3-O-Ethyl Ascorbic Acid powder is widely applied in the cosmetics industry.
Functions of Our 3-O-Ethyl Ascorbic Acid Powder
According to clinical research and commercial formulations, 3-O-Ethyl Ascorbic Acid can inhibit tyrosinase activity and reduce melanin synthesis. It is commonly combined with niacinamide, arbutin, or kojic acid as a multi-ingredient formulation. In this way, they improve the skin tone and make the skin brighter with multi-pathway synergistic effects.
Sunjoy 3-O-Ethyl Ascorbic Acid is suitable for products such as high-performance dark spot corrector serum/cream and brightening masks. You can apply it to skin-brightening products like these and highlight the functions of improving the skin tone and reducing dark spots.
Sunjoy EAC powder can be gradually converted into active L-ascorbic acid in the skin. This process promotes collagen synthesis, especially Collagen I. In this way, it helps improve skin elasticity and reduce the appearance of fine lines
Sunjoy EAC product is ideal for premium anti-ageing formulations. You can develop first-signs-of-aging serums, anti-wrinkle creams, and intensive repairing lotions targeting skin sagging and premature aging.
Conventional Vitamin C powder is easily dissolved when exposed to light. 3-O-Ethyl Ascorbic Acid has exceptional light stability. It is significantly more stable against light than L-ascorbic acid. This allows it to help protect skin against oxidative stress throughout the day. It is highly suitable for the trendy skin care method: “Vitamin C in the Morning, Vitamin A at Night”.
You can utilize it to develop stable and reliable morning defense products that protect the skin from daily oxidative stress without risk of discoloration or loss of efficacy by oxidation.
Formulation mechanisms showcase that 3-O-Ethyl Ascorbic Acid plays a great role in inhibiting inflammatory factors. This helps reduce the appearance of post-inflammatory hyperpigmentation (PIH) after breakouts.
Sunjoy VCE powder is an effective active ingredient for post-acne care. We recommend developing soothing recovery creams and targeted blemish-clearing gels with this ingredient. You can market the products by aiming at calming irritated skin and accelerating the clearance of post-acne marks.

Anti-Caking Formula: Sunjoy strictly controls water in our product to 0.08% (standard: under 1%). The outstanding dryness helps reduce moisture absorption and highly reduces caking or clumping during long-term storage.
Low Heavy Metal Contamination: Heavy metal is a major contamination source that affects safety. Sunjoy contains a very low level of Arsenic (As), Chromium (Cr), Mercury (Hg), and Lead (Pb), which completely meets the standard.
Low Bacteria Contamination: Bacteria are another main source that influences safety. Sunjoy produces in a cleanroom to reduce microbial load. With our EAC powder, your final products easily meet international quality requirements.
Step 1: Protection of Hydroxyl Groups: Sunjoy dissolves the raw material Vitamin C solid evenly and adds acetone as the protective agent. We control the temperature in a specific range and stir the solution to ensure the ingredients react properly. The acetone molecules lock the non-target sites of the VC molecule. The system generates a stable protective intermediate eventually.
Step 2: Etherification: Our operator applies the protective intermediate to the reaction system. The operator adds an ethylating agent to the reactor with inner pressure and reaction time automatically controlled. The ethyl group attaches to the specific site on the Vitamin C molecule. In this way, the mixture converts to the etherified compound.
Step 3: Deprotection and Impurity Separation: After the reaction is finished, we apply a catalyst to the system. The catalyst removes the acetone protecting group we applied in the first step to restore the original VC structure and activity. Then, we add extraction solvents such as ethyl acetate to the system. With the technology of liquid-phase separation, our advanced equipment separates and discharges the extra reagents, byproducts, and process wastewater into layers.
Step 4: Recrystallization and Dehydration: The refined solution gets into the crystallization tank automatically. The system controls the speed of cooling to ensure the mixture precipitates crystals naturally. The material is processed with centrifugal filtration and multiple washings.
Then, our operator sends the crystals into the vacuum drying oven for dehydration. The dried crystals are crushed and sieved by the equipment. After all these procedures, we get high-purity 3-O-Ethyl Ascorbic Acid powder.
Step 5: Packaging: We offer two packages for different volumes of orders. For small volume orders, such as 1 kg, 5kg, and 10 kg, we pack the EAC powder into Aluminum foil bags; for large volumes like 50 kg, we pack the powder into cardboard drums with plastic bags inside. We protect your ingredients from light and moisture exposure as long as the packages are not opened.

You can follow this guidance to dissolve EAC powder for its best performance.
Temperature control
Mild heating can accelerate the dissolution of EAC powder. You should control the temperature below 60 °C to prevent affecting stability.
Stirring Method
You can use a magnetic stirrer or a glass rod to stir at a steady speed. In this way, the solution will have even dispersion.
Addition Order
We suggest you add the solvent first, then add the EAC powder slowly.
Concentration Control
You can gradually adjust the concentration based on your demand and avoid adding too much at one time.
Notices
The whole procedure of dissolving takes 30 minutes to an hour in general. It depends on the specific solvent type, temperature, and stirring intensity. If precipitation occurs, you can improve this by mild heating and adjusting the portion of the powder and solvent.
After dissolution, you should control the stability. The solution should be kept from light to prevent oxidation. We recommend you control the pH between 3.5 and 4.5 to maintain stability.
In the next few years, the market demand for 3-O-Ethyl Ascorbic Acid powder tends to increase. Here are the two major factors.
Meet the Consumers’ Requirements Perfectly
Today, consumers tend to purchase products with natural, safe, and effective ingredients. Compared to regular VC, the derivative is stable and easily absorbed by the skin. 3-O-Ethyl Ascorbic Acid performs excellently in brightening the skin as an antioxidant. More and more skin care brands are starting to choose it as the core ingredient of their products.
Lower Costs Bring A Broader Market
Due to the progress of technology and manufacturing processes, the production costs of 3-O-Ethyl Ascorbic Acid powder tend to decrease. The price is becoming more competitive than in the past. This allows the ingredient to be utilized in mass market products instead of being limited to premium products only.
For regular products aimed at the mass market, we recommend applying a 0.5% to 5% dosage of 3-O-Ethyl Ascorbic Acid.
For the premium product line, especially serums, we suggest applying a 5% to 10% dosage.
We advise you to store 3-O-Ethyl Ascorbic Acid Powder in dry, cool environments without direct sunlight. When the package is opened, please seal it every time after use to prevent absorption of moisture. Under proper conditions, the powder can maintain stability in the long term.
The key difference is their performance in formulations. Ascorbic Acid is very powerful, but it is too fragile that can only perform well under low pH conditions (best below pH 3.5). 3-O-Ethyl Ascorbic Acid is gentle for the skin and is much more stable in general pH conditions.
If your products are aimed at instant and intensive results, Ascorbic Acid is your first choice. It should be strictly protected from air and light during storage. The common applications are clinical treatments, waterless oils, or dry powder products.
If your brand is developing common water-based serums, face creams, or clear lotions that require a long shelf life and are gentle for daily usage, 3-O-Ethyl Ascorbic Acid is your optimal choice. It is also ideal when you need to combine VC with other active ingredients like Niacinamide in your cosmetic products.
Here is a comparison table for quick reference. If you are still confused about which type to purchase, you are welcome to consult our service team for specific guidance.
