Description
Specification:
Ethyl Ascorbic Acid (3-O-Ethyl Ascorbic Acid) is a stable derivative of ascorbic acid,with the molecular formula C₈H₁₂O₆. It retains the core ascorbic acid (lactone ring) structure,with an ethyl ether group (–OC₂H₅) replacing one of the hydroxyl groups at the 3-position.This modification protects the molecule from the rapid oxidation that plagues standard L-ascorbic acid.
Its key advantage over plain Vitamin C,pure L-ascorbic acid is notoriously unstable as it oxidizes and degrades quickly when exposed to light,air,and water,losing efficacy and often turning a formulation yellow/brown over time. Ethyl ascorbic acid is far more stable in aqueous formulations while still functioning as a source of active vitamin C once it penetrates the skin (it’s converted to free ascorbic acid within the skin after absorption).

Applications of Ethyl ascorbic acid:
1.Skincare,used in brightening and antioxidant serums (main use)
>Skin brightening/lightening products,used to inhibit melanin production (tyrosinase inhibition), helping to fade hyperpigmentation, dark spots, and uneven skin tone.
>Antioxidant serums and creams,provides free-radical-scavenging antioxidant protection against environmental damage (UV exposure, pollution) similar to standard Vitamin C, but with much better shelf stability.
>Anti-aging formulations,supports collagen synthesis stimulation, similar to other Vitamin C derivatives, helping improve skin firmness and texture over time.
2.Stable alternative in water-based formulations
Because of its resistance to oxidation, it’s specifically favored in formulations where standard L-ascorbic acid would degrade too quickly,allowing to create effective, longer-shelf-life Vitamin C serums, essences, and lotions without the discoloration and potency loss issues of the pure acid form.
3.Combination formulations
Frequently paired with other actives like niacinamide, hyaluronic acid, or other vitamin C derivatives (e.g., sodium ascorbyl phosphate, magnesium ascorbyl phosphate) in multi-functional brightening and anti-aging products.
4.Sensitive skin formulations
Generally considered gentler and less irritating than pure L-ascorbic acid, which can cause stinging or irritation at the higher concentrations often needed for efficacy,making ethyl ascorbic acid a good option for sensitive-skin-targeted brightening products.
Safety of 3-O-Ethyl Ascorbic Acid:
It is ordinary product,the MSDS of it can be provided.
Practical formulation note: Ethyl ascorbic acid is valued by formulators specifically because it solves the two biggest problems with using Vitamin C in skincare,instability and irritation potential,while still delivering the brightening, antioxidant, and collagen-supporting benefits associated with the ingredient. It’s considered one of the more advanced, stable Vitamin C derivatives currently used in cosmetic chemistry.
