PEG-4 OLIVATE.

Valuable CAS 226708-41-4 / SURFACTANT - EMULSIFYING

PEG-4 Olivate is a versatile, olive oil-derived ingredient primarily functioning as an effective co-emulsifier to stabilize oil-in-water formulations. It significantly enhances the sensory experience of skincare products, imparting a smooth, soft feel, and provides notable moisturizing benefits to the skin.

Emulsifying Moisturizing Humectant Emollient Sensorial Modifier Formulation Stabilizer Penetration Enhancer

Science

Mechanism of Action

On a molecular level, PEG-4 Olivate acts to bridge immiscible oil and water phases, forming stable oil-in-water emulsions crucial for consistent product formulations. It functions as a humectant and emollient, attracting and retaining moisture in the skin, thereby enhancing softness, elasticity, and overall hydration. Furthermore, it modulates the skin's surface, contributing to a refined and pleasant after-feel, and can potentially improve the dermal penetration of other active compounds in a formula.

Stability

This ingredient significantly enhances the stability and structural integrity of oil-in-water emulsions, improving texture and contributing to formulation viscosity. Its physical state can range from liquid to wax-like depending on its degree of polymerization, influencing the final texture of the cosmetic product.

Synergies

  • Enhances emulsion stability when combined with primary emulsifiers.
  • May improve active ingredient delivery due to its penetration-enhancing properties.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed PEG-4 Olivate as safe for use in cosmetic applications, specifically noting its inclusion in a 2014 re-review of PEG compounds. Studies consistently demonstrate a low incidence of adverse effects and rare allergic reactions, underscoring its favorable safety profile. While PEG compounds may carry a theoretical risk of trace contamination with 1,4-Dioxane and Ethylene Oxide (byproducts of the ethoxylation process), stringent industry purification protocols are employed to reduce these impurities to virtually undetectable levels.
