Full Description

3-O-Ethyl ascorbic acid (CAS 86404-04-8) is the 3-O-ethyl ether of L-ascorbic acid (vitamin C), supplied as a cosmetic and personal-care raw material. Etherifying the 3-hydroxyl improves oxidative stability relative to free ascorbic acid, and the molecule carries both water- and oil-compatible character for use across aqueous and anhydrous formulations.

Frequently Asked Questions

What is the difference between ascorbic acid and ethyl ascorbic acid?

3-O-Ethyl ascorbic acid (CAS 86404-04-8) is the 3-O-ethyl ether of L-ascorbic acid (vitamin C). Etherifying the 3-hydroxyl improves oxidative stability relative to free ascorbic acid and gives the molecule both water- and oil-compatible character. It is supplied as a cosmetic and personal-care raw material.

Is ethyl ascorbic acid water- or oil-soluble?

The molecule carries both water- and oil-compatible character, making it usable across aqueous and anhydrous formulations. This dual solubility is a key formulating advantage over free ascorbic acid. Confirm solvency against your specific carrier system.

What form does RawSource supply ethyl ascorbic acid in?

It is typically supplied as a powder raw material for personal-care formulation. RawSource distributes it in bulk with CoA and SDS provided per shipment. Specify purity and quantity when requesting documentation.

What is the CAS number and molecular formula?

The CAS number is 86404-04-8 and the molecular formula is C8H12O6. RawSource provides identity documentation and a CoA with each shipment for incoming-QC verification.

What is the cost of bulk ethyl ascorbic acid?

Pricing depends on purity grade, packaging, and volume. Submit a bulk RFQ with your specification and quantity for a current quote; we do not publish spot prices.
