Product: Ethyl Ascorbic Acid (EAA)
Rchem Ethyl Ascorbic Acid is a highly stable, oil-soluble derivative of Vitamin C, presented as a white to slightly yellow crystalline powder. This advanced form of Vitamin C is engineered to overcome the notorious instability of pure L-Ascorbic Acid while retaining its potent brightening and antioxidant benefits. Its unique lipid-soluble structure allows for enhanced skin penetration and compatibility with oil-based formulations, making it an ideal choice for manufacturers creating high-performance, stable serums, creams, and treatments that target hyperpigmentation, dullness, and photoaging.

Frequently Asked Questions:
How does Ethyl Ascorbic Acid compare to L-Ascorbic Acid?
While L-Ascorbic Acid is the pure, active form, it is highly unstable. EAA is a stable derivative that is converted to L-Ascorbic Acid in the skin. EAA offers superior formulation flexibility (oil-soluble), longer shelf life, and gentleness, though it may be slightly less potent on a molecular equivalency basis than freshly prepared L-Ascorbic Acid.
Due to its oil-soluble nature, it is not directly soluble in water. For water-based serums, it must be solubilized using emulsifiers or delivered through a nano-emulsion system. It is most straightforwardly used in oil phases, anhydrous serums, and emulsions.
Can EAA be used in water-based formulations?
Yes, this is a key advantage. Unlike L-Ascorbic Acid, which requires a low pH (<3.5) for stability and penetration, EAA is effective and stable at a wider, more skin-compatible pH range (up to pH 7), making it easier to formulate with and gentler on the skin.
Is EAA effective at a neutral pH?
Yes, it is highly compatible. Its stability at near-neutral pH makes it an excellent partner for Niacinamide. It can also be used with Retinol, but as with any potent active combination, it is advisable to monitor skin tolerance and ensure the overall formulation is well-balanced to avoid irritation.
Can EAA be combined with other active ingredients like Niacinamide and Retinol?
EAA is one of the most effective and well-researched Vitamin C derivatives. Its key differentiators are its oil solubility, which allows for unique formulation possibilities and enhanced penetration into the lipid layers of the skin, and its exceptional stability, which guarantees product integrity from production to the last use.
