TOCOPHERYL ETHYLASCORBYL PEG-4 BIS-SUCCINATE.

Insufficient Data / ANTI-SEBUM, ANTIOXIDANT

This advanced ingredient combines a potent lipo-soluble antioxidant, tocopheryl (Vitamin E), with a stable derivative of Vitamin C, ethylascorbyl, linked via a PEGylated succinate. Engineered for enhanced skin penetration and efficacy, it offers robust antioxidant protection and targeted sebum regulation.

Antioxidant Anti-sebum

Science

Mechanism of Action

TOCOPHERYL ETHYLASCORBYL PEG-4 BIS-SUCCINATE operates through a synergistic mechanism. The tocopheryl component functions as a primary lipo-soluble antioxidant, protecting dermal lipids from oxidative damage caused by free radicals, UV radiation, and environmental aggressors, thereby supporting skin rejuvenation and preventing premature aging. It also demonstrably acts as an anti-sebum agent, assisting in the normalization of skin oil production. The PEGylated succinate linker serves as an amphiphilic surfactant and solubilizer, forming micelles that significantly increase the solubility and bioavailability of both the Vitamin E and Vitamin C derivative, facilitating their optimal absorption and delivery within the skin.

Stability

This ingredient is expected to exhibit good stability in formulations and may contribute to overall formulation stability due to its amphiphilic and surfactant characteristics. An analogous compound, d-alpha-tocopheryl polyethylene glycol 1000 succinate (TPGS), demonstrated marginal ester bond degradation of 3.4% ± 0.4% at pH 1.0 and 37°C over an 8-hour period, suggesting robust stability under acidic conditions.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Unknown

The Cosmetic Ingredient Review (CIR) Expert Panel has not specifically reviewed TOCOPHERYL ETHYLASCORBYL PEG-4 BIS-SUCCINATE. However, the CIR has deemed 'Tocopheryl Succinate' safe for cosmetic use at concentrations up to 0.038%, and has concluded that 14 tocopherols and tocotrienols are safe. General polyethylene glycols (PEGs) typically exhibit low oral and dermal toxicity and minimal skin irritation in acute studies on intact skin. It is pertinent to note that sensitization and nephrotoxicity have been documented in burn patients treated with PEG-based creams. The SCCS has opined that alpha-tocopherol acetate is safe; however, some comparative studies suggested that alpha-tocopherol succinate might enhance skin cancer development in specific experimental contexts, though this was not the overarching conclusion for the acetate form. Due to its complex and combined nature, specific safety data for this exact compound are currently insufficient.
