PEG-80 HYDROGENATED DIMER DILINOLEATE.

Insufficient Data CAS - / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

PEG-80 Hydrogenated Dimer Dilinoleate serves as a multi-functional ingredient, primarily acting as a surfactant and emulsifier to stabilize oil-in-water cosmetic formulations. It also offers potential humectant properties for enhanced skin hydration and functions as a conditioning agent to improve the texture of both skin and hair.

Science

Mechanism of Action

As a surfactant, PEG-80 Hydrogenated Dimer Dilinoleate effectively lowers interfacial tension, facilitating the homogeneous blending of immiscible oil and water phases within a product. The polyethylene glycol (PEG) portion is anticipated to attract and retain moisture, thereby contributing humectant benefits to the skin. Concurrently, the Dimer Dilinoleate component functions as a skin-conditioning agent and can modulate product viscosity.

Stability

An optimal pH range for formulation stability is likely between 6.0 and 7.0, inferred from similar PEG-80 Sorbitan Laurate.

Synergies

  • Compatibility with anionic and cationic surfactants is noted for PEG-80 Sorbitan Laurate, a related compound.

Conflicts

  • Polyethylene glycols (PEGs) can potentially interfere with the performance of some thickeners and emulsifiers, which may lead to formulation instability or phase separation.

Insufficient data
Sensitization risk Unknown

The Cosmetic Ingredient Review (CIR) Expert Panel has not specifically reviewed PEG-80 Hydrogenated Dimer Dilinoleate. A Scientific Literature Review Notice for 'Dimer Dilinoleates' was issued in February 2025, highlighting substantial data deficiencies. However, related 'dialkyl dimer dilinoleates' have been deemed safe, with some used at concentrations up to 53% in lipsticks. Separately, 'PEG Sorbitan/Sorbitol Fatty Acid Esters' (which share a PEG-80 component) were concluded safe for cosmetic use up to 25%. The potential presence of 1,4-dioxane, a byproduct of ethoxylation, is a general consideration for all PEG ingredients.

Verdict

Insufficient Data

While PEG-80 Hydrogenated Dimer Dilinoleate is expected to perform valuable functions as an emulsifier and conditioning agent, comprehensive safety and efficacy data for this specific ingredient remain insufficient according to current scientific reviews.
