PEG-80.

Valuable CAS 25322-68-3 / BINDING, HUMECTANT, SOLVENT

PEG-80 Sorbitan Laurate is a water-soluble polyoxyethylene derivative of sorbitan monolaurate, functioning primarily as a versatile surfactant. It effectively solubilizes fragrances, controls viscosity, and acts as an emulsifier to blend oil and water components, ensuring stable and homogenous formulations.

Summary

Surfactant Emulsifying Agent Cleansing Agent Solubilizing Agent Emollient Anti-irritant

Science

Mechanism of Action

This ingredient functions by significantly reducing the surface tension between immiscible phases within a formulation, thereby enabling oil and water-based ingredients to mix thoroughly and form stable emulsions, particularly oil-in-water systems. Its cleansing action allows it to encapsulate and facilitate the rinsing away of oil and dirt, contributing to skin purification and potentially aiding in acne management. Furthermore, PEG-80 Sorbitan Laurate provides emollient benefits, which help to moisturize and soften the skin, and can mitigate irritation in complex surfactant mixtures.

Stability

Optimal stability for PEG-80 Sorbitan Laurate is reported within a pH range of 6.0-7.0. Like other PEGs, it may render formulations acidic upon dissolution, potentially requiring pH adjustment. Stability can be compromised by exposure to light, elevated temperatures (specifically above 40°C), peroxides, and trace metals, which may accelerate oxidative degradation. Higher concentrations might offer a degree of protection against such oxidative processes.

Synergies

  • Enhances anti-irritation properties when incorporated into mixed surfactant systems.

Conflicts

  • Potential for oxidative degradation when exposed to light, heat (especially 40°C), peroxides, and trace metals.

Safety

Safety Profile

CIR Status
Safe with restrictions
Max tested
25%
Sensitization risk Low

The CIR Expert Panel has concluded that PEG Sorbitan/Sorbitol Fatty Acid Esters, encompassing PEG-80 Sorbitan Laurate, are safe for use in cosmetics at concentrations not exceeding 25.0%. A crucial restriction is that these ingredients should not be applied to damaged skin. Specifically, PEG-80 Sorbitan Laurate is considered safe for use up to 10.0% concentration in skin and hair products. While trace amounts of 1,4-dioxane, a byproduct of the ethoxylation process, may be present, manufacturers control these levels through purification, and the FDA monitors cosmetics to ensure they contain safe amounts.
