Product Description
Ethyl Ascorbic Acid, also known as 3-O-Ethyl Ascorbic Acid or Vitamin C Ethyl Ether, is a vitamin C derivative used in cosmetic formulations for skin-brightening, antioxidant, and tone-evening applications. For cosmetic ingredient buyers, selection should focus on chemical identity, assay, solubility, formulation stability, and compatibility with the finished product.
Vitamin C Ethyl Ether is a chemically modified vitamin C derivative developed for topical cosmetic applications. Its ethyl group changes the compound's physicochemical properties compared with ascorbic acid, making it a useful ingredient for formulators developing serums, creams, lotions, and other skincare products. It is commonly selected for formulas intended to improve the appearance of uneven skin tone and provide antioxidant support.
For accurate procurement, buyers should specify 3-O-Ethyl Ascorbic Acid rather than relying on the broad term “vitamin C ethyl ether” alone. Confirm the INCI name, CAS number, assay method, and product specification to ensure that quotations and technical documents refer to the same ingredient.
| Item | Specification |
|---|---|
| Product name | Ethyl Ascorbic Acid |
| Common names | 3-O-Ethyl Ascorbic Acid; Vitamin C Ethyl Ether |
| Ingredient category | Vitamin C derivative; cosmetic active ingredient |
| INCI name | 3-O-Ethyl Ascorbic Acid |
| CAS number | 86404-04-8 |
| Molecular formula | C8H12O6 |
| Molecular weight | 204.18 g/mol |
| Typical appearance | White to off-white crystalline powder |
| Common assay grade | Cosmetic grades commonly target 98% or higher; confirm the applicable release limit in the agreed specification |
| Identification and assay | HPLC or another validated chromatographic method, with suitable identification testing |
| Solubility | Generally water-compatible; actual dissolution behavior depends on temperature, concentration, pH, and the full formulation |
| Typical applications | Brightening serums, facial creams, lotions, essences, and other topical skincare products |
| Recommended storage | Keep tightly sealed in a cool, dry place, protected from moisture, excessive heat, and direct sunlight |
| Typical shelf life | Commonly 24 months under recommended storage conditions; follow the lot-specific label and COA |
| Common packaging | 1 kg or 5 kg sealed foil bags; bulk orders may use suitable larger containers, such as 25 kg drums, depending on the supply format |
| Particle size | Defined by the product specification; customized requirements can be discussed for processing or formulation needs |
| Quality documents | Typical documentation includes a product specification and batch COA; additional technical and safety documents depend on the supply program |
For 3-O-Ethyl Ascorbic Acid, the main purchasing question is whether the ingredient will remain compatible with the intended skincare system throughout manufacturing and storage. A high assay is useful, but it does not by itself demonstrate that the active will dissolve properly or that the finished formula will maintain its intended appearance and performance.
For water-based serums and essences, assess dissolution at the intended use concentration and processing temperature. For emulsions such as creams and lotions, check the addition phase, mixing sequence, and compatibility with the emulsifier system. Avoid assuming that the same addition method will work equally well across all product types.
Evaluate the finished formula across its intended pH range and monitor appearance, color, odor, and relevant assay results during stability testing. The stability of the ingredient in isolation does not guarantee stability in a formula containing fragrances, botanical extracts, metals, preservatives, or other active ingredients.
Request the same information from each candidate supplier: ingredient identity, assay limit, analytical method, appearance, batch COA, storage instructions, and traceable lot details. If a project has a defined color limit, impurity requirement, or processing constraint, include it in the purchasing specification rather than relying on a generic grade description.
Ethyl Ascorbic Acid is used in facial serums and essences formulated to improve the appearance of dullness and uneven skin tone. The finished formula should be assessed for dissolution, clarity, color stability, and compatibility with other active ingredients.
It can be evaluated in emulsified skincare products intended to support a more even-looking complexion and provide antioxidant benefits. Formulators should establish the appropriate addition phase and confirm stability in the complete emulsion.
For formulas combining vitamin C derivatives with botanical extracts, niacinamide, exfoliating ingredients, or other actives, compatibility should be demonstrated through formulation trials. Ingredient interactions and the overall pH can affect the finished product's stability and sensory properties.
Common commercial packaging includes sealed 1 kg and 5 kg foil bags for laboratory work, pilot batches, and smaller production runs. Larger orders may be supplied in suitable bulk packaging, such as 25 kg drums, depending on the supply format. Keep the container closed between uses and protect the material from moisture, heat, and direct light.
Ethyl Ascorbic Acid can be considered for OEM and private-label skincare projects involving brightening serums, facial creams, lotions, and related topical products. Development work may include active-level selection, base-formula compatibility, packaging evaluation, stability testing, and label-claim review. The finished product should be assessed against the regulations and cosmetic-claim requirements of each intended market.
Raw-material qualification should include identity confirmation, assay testing, appearance checks, and review of relevant impurity controls where specified. HPLC is commonly used for assay evaluation, while the exact analytical procedure and acceptance criteria should follow the approved product specification. Review the batch COA, lot traceability, shelf-life information, storage conditions, and applicable safety documentation before use.
Raw-material specifications do not replace finished-product testing. Cosmetic manufacturers should validate the complete formulation, packaging compatibility, stability, and substantiation for any product claims before commercialization.
In cosmetic ingredient sourcing, Vitamin C Ethyl Ether commonly refers to 3-O-Ethyl Ascorbic Acid, also called Ethyl Ascorbic Acid. Buyers should still verify the INCI name, CAS number, and specification on the supplier's documents to ensure that the quoted ingredient matches the intended material.
Cosmetic grades commonly target an assay of 98% or higher, but the acceptance limit should be based on the agreed specification and validated analytical method. Buyers should also review identity, appearance, relevant impurity limits, batch consistency, and documentation instead of using assay as the only purchasing criterion.
No single ingredient is suitable for every formula. Its use depends on the product format, intended concentration, pH, processing conditions, packaging, and compatibility with other ingredients. Conduct formulation and stability testing, and confirm the applicable requirements in the target market before commercial launch.
Ethyl Ascorbic Acid is a vitamin C derivative used in cosmetic products developed for brightening and antioxidant applications. For reliable sourcing, confirm the exact ingredient identity, agreed assay specification, analytical method, packaging needs, and suitability for the intended formulation.
