Technical Specification
D-alpha-Tocopheryl Acetate, also known as **natural vitamin E acetate**, is one of the most biologically active forms of vitamin E. It appears as a pale yellow, clear viscous oil with excellent oxidation resistance and stability. Unlike synthetic vitamin E, natural D-alpha-Tocopheryl Acetate offers higher absorption efficiency and safer performance for human and animal applications. It helps protect fats, oils and nutrients from oxidation damage, extend product shelf life, and maintain nutritional value during processing and storage.

Safety Profile
Safety Performance & Toxicological Data
- Skin Irritation: Acute skin irritation test (rabbit): Non-irritating; 28-day repeated patch test on human skin: No erythema, edema or itching reaction, low sensitization risk, suitable for sensitive skin.
- Eye Irritation: Rabbit eye irritation test: Mild irritation, avoid direct contact with eye mucosa during operation.
- Dermal Absorption: Low percutaneous systemic absorption, no cumulative toxicity under normal cosmetic use concentration.
- Comedogenicity: Non-comedogenic, will not block pores or induce acne.
- Authoritative Safety Assessment: Compliant with CIR (Cosmetic Ingredient Review) and SCCS (Scientific Committee on Consumer Safety) safety regulations. CIR confirms that the raw material is safe when the addition amount is within the limited range of cosmetic formulas.
Usage Safety Limit (Clear Quantified Standard)
- Leave-on cosmetic products: Maximum safe usage concentration ≤36% (conventional recommended dosage 0.5%–2.0%)
- Rinse-off cosmetic products: Maximum safe usage concentration ≤10%
- Lip balm, body butter and intensive repair products: The maximum allowable addition is 5%

Frequently Asked Questions
What is the difference between D-alpha-Tocopheryl Acetate and DL-alpha-Tocopheryl Acetate?
-
D-alpha-Tocopheryl Acetate is the natural-source Vitamin E ester with higher biological activity. DL-alpha is synthetic. Our D-alpha form offers better skin affinity and antioxidant efficacy for high-end cosmetics.
Is D-alpha-Tocopheryl Acetate suitable for sensitive skin?
-
Yes. It is mild, non-irritating, anti-inflammatory, and helps soothe redness or discomfort. Widely used in sensitive-skin and repair formulations.
What is the recommended usage rate in cosmetics?
-
Typical range: 0.5% – 2.0%; can be increased to 5% in balms, butters, or intensive repair products.
Can D-alpha-Tocopheryl Acetate replace preservatives?
-
No. It inhibits oil oxidation but does not kill bacteria or fungi. Water-based formulas still need a full-spectrum preservative system.
How to store to ensure stability?
-
Keep tightly sealed in a cool, dry, dark place; avoid high temperatures, direct light, and strong acids/alkalis to prevent hydrolysis.
