Tetrahexyldecyl Ascorbate VC-IP Liposoluble Vitamin C Raw Material CAS 183476-82-6

Tetrahexyldecyl Ascorbate, commonly known as VC‑IP, is a highly stable liposoluble vitamin C derivative and a popular brightening antioxidant active ingredient for skincare formulas. This cosmetic‑grade material is light yellow transparent oily liquid, with excellent oil solubility. It can be dissolved directly in vegetable oils, synthetic esters, silicones and other oil phases and is insoluble in water. It effectively solves the drawbacks of pure L‑ascorbic acid such as easy oxidation, strong irritation and poor formula stability. VC‑IP features superior skin penetration. It can pass through the sebum film and gradually convert into active vitamin C inside the skin for sustained efficacy. It inhibits melanin production, fades dullness and pigmentation, evens skin tone, scavenges free radicals efficiently, protects skin from oxidative damage caused by UV and environmental stress, stimulates collagen synthesis and improves fine lines and sagging, delivering brightening, antioxidant and anti‑aging benefits simultaneously. It has a mild odor and good compatibility with other ingredients with much lower discoloration risk than raw vitamin C, ideal for long‑stable brightening anti‑aging products. We supply high‑purity VC‑IP. Every batch is fully tested by HPLC assay, heavy metal and microbiology inspection to maintain stable specifications. Samples are available for formulation trial, accelerated stability test and efficacy evaluation. Full documents including COA, TDS and SDS are supplied. The product complies with REACH, GMP, ISO22716, FDA, HALAL, KOSHER standards for global cosmetic filing.

As a liposoluble stable vitamin C derivative, VC‑IP is widely applied in brightening antioxidant and anti‑repair skincare formulas. It is the preferred brightening ingredient for oil‑based formulas, anhydrous formulas, oil serums and oil creams. It is commonly incorporated into brightening facial oil, anti‑aging cream, moisturizing lotion, firming eye cream, skincare foundation, sunscreen, after‑sun repair oil and nourishing masks for skincare and color cosmetics. It has great compatibility with oils, silicones, retinol derivatives, peptides, Pro‑Xylane, Coenzyme Q10 and botanical extracts, bringing synergistic effects on antioxidant, wrinkle reduction and brightening. Compared with pure vitamin C, it is less irritating when combined with retinol and less likely to trigger redness. As an oil‑soluble raw material, it is recommended to add during oil phase for O/W and W/O emulsions; solubilizer or emulsifier system is required if used in water‑based formulas. Long‑time overheating should be avoided during production. A small amount of antioxidant can be added to extend shelf life and reduce color shift. It is highly suitable for premium lines focusing on gentle brightening, anti‑photoaging and mature skin anti‑aging. We can provide technical advice according to your formula system and complete compliance documents to support formulation development and export filing for cosmetic manufacturers and brands.

We provide standard industrial packing solutions and support customized packaging upon request. There are two regular packing sizes: 1kg vacuum aluminum foil bag for sample testing, laboratory formulation trial and small‑batch production; 25kg food‑grade sealed plastic drum for mass industrial production procurement. All packages are equipped with internal moisture‑proof layers to block moisture and light, preventing activity loss of raw materials during storage and transportation. It should be stored in sealed, light‑proof, cool and dry conditions, away from heat sources, open flames and strong oxidants, and avoid drastic temperature changes. The shelf life is 24 months for unopened products. Once opened, it is recommended to consume as soon as possible. Residual materials need to be re‑sealed and stored away from light under refrigeration to avoid degradation of active components. We also offer neutral packing and private label packing services to meet export and repackaging demands of different brands.
