PEG-8 AVOCADOATE.

Valuable / SURFACTANT - EMULSIFYING

PEG-8 Avocadoate is an ethoxylated derivative of avocado oil, harnessing the oil's natural richness in vitamins A and E, alongside beneficial unsaturated fatty acids. This versatile ingredient provides significant skin conditioning, humectant, and emulsifying properties to improve both product formulation and skin health.

Emollient Emulsifying Skin Conditioning Surfactant Humectant

Science

Mechanism of Action

This ingredient functions primarily as an emollient, delivering nourishing compounds from avocado oil, such as Vitamins A and E and essential fatty acids, to the skin. This action promotes a smooth, supple texture, protects against moisture loss, and supports cellular regeneration, particularly benefiting brittle or flaky skin. As a humectant, it attracts and retains water in the epidermis, while its surfactant and emulsifying capabilities reduce surface tension, enabling the formation of stable oil-in-water mixtures for effective cleansing and formulation stability.

Stability

PEG-8 AVOCADOATE demonstrates good stability, resisting moderately strong acids, alkalis, and salt solutions. It is susceptible to oxidative degradation in the presence of air and elevated temperatures; therefore, minimizing oxygen exposure or incorporating antioxidants is advisable. The ingredient maintains its integrity upon storage, does not hydrolyze, and does not support mold growth. Its optimal pH range for efficacy at a 1:20 concentration is between 4.0 and 7.5.

Safety

Safety Profile

CIR Status
Safe as used
Max tested
100%
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that PEGylated oils, including PEG-8 AVOCADOATE, are safe for use in cosmetics at concentrations up to 100% when formulated to be non-irritating. However, it should not be applied to damaged skin due to the potential for systemic absorption, which has been associated with kidney damage in burn patients treated with PEG-based topical products. Trace amounts of 1,4-dioxane, a byproduct of ethoxylation, may be present but can be controlled through purification processes. PEG-8 itself has been identified as a mild sensitizer and irritant in some clinical studies.

Verdict

Valuable

PEG-8 AVOCADOATE is a valuable, multi-functional ingredient for enhancing skin hydration and texture, and for its emulsifying properties, though its use requires careful consideration for individuals with compromised or highly sensitive skin.
