Tetrahexyldecyl Ascorbate (THDA), Deodorized 1 kg

Tetrahexyldecyl Ascorbate, often abbreviated as THDA, is a ultra-stable, oil-soluble form of Vitamin C engineered for high-performance skin care and anti-aging treatments. Unlike traditional L-ascorbic acid, which decomposes rapidly in water-based media and causes skin irritation, this deodorized lipidic ester penetrates deep into the dermal layers due to its affinity with the natural cutaneous lipid barrier. Upon absorption, biological enzymes convert THDA into active Vitamin C, stimulating collagen synthesis, inhibiting melanogenesis, and neutralizing free radical damage caused by ultraviolet exposure and environmental stress. The advanced deodorization process eliminates harsh, undesirable processing odors, providing formulators with an odorless, clear ester that maintains aesthetic purity in unfragranged products and fine emulsions.

Globally, cosmetic chemists and luxury skincare brands favor Tetrahexyldecyl Ascorbate as the benchmark lipophilic Vitamin C ingredient. Its exceptional stability against thermal degradation, light, and oxidation extends product shelf life significantly without requiring dark or airtight packaging. Incorporating THDA allows formulators to create clear facial oils, luxurious anhydrous serums, and rich lipidic emulsions that remain stable across diverse storage conditions.

Multifunctional Applications Across Beauty and Personal Care Manufacturing

In modern skin care formulations, Tetrahexyldecyl Ascorbate acts as a potent brightening agent, structural collagen booster, and lipid-protecting antioxidant. It reduces hyperpigmentation, unifies skin tone, and restores elasticity in mature skin. Because of its lipid nature, it blends harmoniously with hydrophobic cosmetic lipids, botanical oils, active peptides, ceramides, and lipidic antioxidants like tocopherol, enhancing their overall bioavailability.

In hair care products, THDA protects hair shafts against lipid peroxidation, maintains scalp health, and enhances natural shine in leave-in conditioning oils and scalp treatments. Within color cosmetics and decorative formulations, it functions as an active skin conditioning agent in liquid foundations, radiant primers, lip oils, and lipsticks, providing anti-aging benefits alongside smooth cosmetic application. For hand-crafted soap making, cold-process artisans incorporate THDA into luxury oil phases after trace or in post-saponification creams to enrich the final cleansing bar with protective vitamins. In fragrance and perfumery applications, it acts as a stabilizing antioxidant in oil-based perfume extracts and fine body oils, preserving delicate aromatic compounds against oxidative rancidity without altering the olfactory profile. In topical pharmaceutical and dermatological preparations, THDA serves as an ideal active component in scar recovery ointments and barrier repair balms.

Illuminating Anhydrous Facial Serum with Lipophilic Vitamin C

Squalane - forty milliliters

Rosehip seed oil - thirty milliliters

Jojoba oil - twenty milliliters

Tetrahexyldecyl Ascorbate - seven milliliters

Tocopherol - two milliliters

Bisabolol - one milliliter

In a clean glass vessel, blend the squalane, rosehip seed oil, and jojoba oil together, stirring gently until the oil phase is completely uniform. Add the deodorized Tetrahexyldecyl Ascorbate into the oil mixture and mix thoroughly until fully clarified. Gently incorporate the tocopherol and bisabolol, blending continuously for two minutes to ensure homogeneous dispersion of all active components. Pour the finished liquid into an amber glass bottle equipped with a dropper top.

The resulting facial serum has a silk-like, lightweight liquid texture that absorbs quickly without feeling heavy or leaving a greasy residue. It delivers intense nourishment, brightens dull skin tone, and shields the epidermal barrier against oxidative damage, leaving the complexion smooth, radiant, and deeply hydrated.
