Overview

Ingredient Profile

Ascorbyl tetraisopalmitate, also known as tetrahexyldecyl ascorbate (THD ascorbate), is a fat-soluble derivative of vitamin C. It offers antioxidant protection against environmental stressors and may support collagen synthesis, potentially contributing to improved skin firmness and a more youthful appearance. This stable form of vitamin C is well-suited for oil-based formulations and demonstrates reduced irritation compared to some other vitamin C derivatives.

Role of Ascorbyl Tetraisopalmitate

Active Cosmetic Mechanisms

ANTIOXIDANT

Anti-Aging Protector

Protects products and skin from oxidative damage and aging

SCIENTIFIC ANALYSIS

// Evidence: Antioxidants prevent or delay oxidation by donating electrons to free radicals, chelating pro-oxidant metals, or regenerating other antioxidants. Mechanisms include direct radical scavenging (vitamin E, vitamin C, BHT, BHA), metal chelation (EDTA), or enzymatic action. On skin, they neutralize reactive oxygen species (ROS) generated by UV radiation and pollution, preventing lipid peroxidation and DNA damage.

SKIN CONDITIONING - EMOLLIENT

Skin Softener

Softens and smooths skin by filling gaps between cells

SCIENTIFIC ANALYSIS

// Evidence: Emollient ingredients create smooth, soft skin by filling spaces between corneocytes in stratum corneum. These include esters (isopropyl palmitate), oils (jojoba, argan), fatty alcohols, and silicones. The mechanism involves spreading on skin surface, filling microscopic irregularities, and creating lubricious film. Effects are immediate tactile improvement and visual smoothing. Emolliency measured by spreading coefficient and skin feel assessments.
