Tetrahexyldecyl Ascorbate (THDA), Non-Deodorized 1 kg

Tetrahexyldecyl Ascorbate, commonly known in the formulation world as THDA, represents one of the most stable and effective lipid-soluble derivatives of L-ascorbic acid available to cosmetic chemists today. Unlike traditional water-soluble vitamin C, which rapidly degrades in the presence of light, heat, and air, this lipophilic ester maintains exceptional structural integrity across demanding processing conditions. The non-deodorized grade retains the full natural integrity of its active lipid fraction, delivering uncompromised potency alongside remarkable skin penetration capabilities. Because THDA possesses an affinity for the natural intercellular lipid matrix of the stratum corneum, it traverses the skin barrier far more efficiently than standard ascorbic acid, converting into pure active vitamin C within the dermal layers without inducing surface irritation, redness, or burning sensations.

Formulators globally demand non-deodorized Tetrahexyldecyl Ascorbate for high-performance anti-aging serums, brightening emulsions, protective daily sunscreens, and structural skin barrier treatments. Its growing prominence across international cosmetic markets stems from its multi-targeted biological action. It suppresses melanin synthesis to fade hyperpigmentation, stimulates natural collagen production to firm sagging tissue, neutralizes damaging reactive oxygen species generated by ultraviolet exposure, and reinforces the lipid layer to prevent transepidermal water loss. For development teams and commercial manufacturers, THDA solves historical vitamin C instability challenges while allowing for completely waterless, anhydrous formulations that offer long shelf lives and luxurious, silky sensory profiles.

Technical Efficacy and Applications Across Cosmetics, Personal Care, and Fine Products

In facial skincare, Tetrahexyldecyl Ascorbate functions as an essential active agent in brightening treatments, age-defying night creams, and protective daytime serums. Its lipid-friendly structure blends harmoniously with complex lipidic components, natural botanical oils, essential fatty acids, and active lipophilic peptides, providing a synergistic boosting effect against photoaging. In sun care and post-sun recovery products, THDA works as a powerful cellular defender, reducing UV-induced erythema, scavanging free radicals, and mitigating oxidative degradation of vital cellular lipids.

Beyond facial care, THDA finds versatile utility across multiple formulation sectors. Within specialized body care, it improves elasticity, evens skin tone on areas prone to sun damage, and supports stretch mark recovery gels. In lip care products, it deeply nourishes while encouraging collagen synthesis for smoother, plumper contours. In professional hair and scalp treatments, THDA acts as a protective antioxidant for the scalp lipid layer, defending hair follicles against urban pollution and environmental stressors.

Cosmetic soap making benefits from adding THDA into luxury cold-process and hot-process soap bars or liquid oil-based body washes to introduce antioxidant protection and skin-soothing conditioning properties. The fine fragrance and ambient perfume industry utilizes THDA within scented body oils and anhydrous fragrance balms, where its natural lipophilic carrier nature holds perfume notes while protecting sensitive olfactory components from oxidation. In pharmaceutical and topical dermatological compounding, THDA serves as an ideal stable carrier for therapeutic lipids, soothing skin repair ointments, and post-procedure recovery formulations due to its mild, non-sensitizing profile.

Radiant Youth Anhydrous Vitamin C Facial Elixir

Squalane - sixty-five milliliters

Jojoba oil - twenty milliliters

Rosehip seed oil - ten milliliters

Tetrahexyldecyl Ascorbate Non-Deodorized - three milliliters

Tocopherol - one milliliter

Sea buckthorn fruit oil - one milliliter

In a sterile glass beaker, measure out the squalane, jojoba oil, and rosehip seed oil, stirring gently with a glass rod until completely uniform. Add the Tetrahexyldecyl Ascorbate Non-Deodorized and tocopherol to the oil mixture, blending steadily until completely dissolved into a clear liquid. Finish by adding the sea buckthorn fruit oil to impart a delicate golden tint and extra antioxidant richness. Mix the batch thoroughly for two minutes, then transfer the finished oil serum into a dark amber glass bottle equipped with a dropper top.

The resulting facial elixir features a golden, silky, light liquid texture that glides weightlessly over clean skin and absorbs quickly without leaving a heavy or greasy film. With consistent daily use, this high-potency oil serum visibly brightens uneven skin tone, softens fine lines, restores natural luminosity, and leaves the skin feeling deeply supple, nourished, and velvety soft.
