Science

Mechanism of Action

By modifying almond oil with PEG-8, it becomes soluble in aqueous systems, reducing interfacial tension between oil and water phases. This modification allows for easy rinse-off and effective emulsification, providing both hydration and conditioning.

Key findings

  1. 01 The Cosmetic Ingredient Review (CIR) assessed PEGylated oils, including Almond Oil PEG-8 Esters, as safe for use from 0.05% to 97% when formulated to be non-irritating.
  2. 02 A 4-week rat study involving 40% Apricot Kernel Oil PEG-6 Esters (a related compound) showed a No Observed Adverse Effect Level (NOAEL) of 5 ml/kg/day, supporting the general safety profile of PEGylated fruit/nut oils.

Stability

Stable in water-based systems and emulsions, remaining liquid at room temperature. Its lower molecular weight (PEG-8) contributes to enhanced water solubility and humectant properties compared to higher molecular weight PEGs.

Conflicts

  • Strong oxidizing agents
  • Certain preservatives (e.g., parabens) due to potential micellar encapsulation
