Polyglyceryl-6 Pentaoleate

What is Polyglyceryl-6 Pentaoleate?

Polyglyceryl-6 pentaoleate is a non-ionic emulsifying agent formed by linking a chain of six glycerol molecules with five oleic acid units, a monounsaturated fatty acid sourced from plant oils such as olive or sunflower. Created via esterification, this ingredient belongs to the polyglyceryl ester family commonly used in cosmetic formulations like moisturizers, lotions, and mild cleansers. It functions by positioning itself at the oil-water interface, creating a stable film that prevents phase separation and ensures even distribution of active components. As an emollient, it mimics skin's natural lipids to enhance surface smoothness and reduce evaporation of moisture. Its surfactant properties contribute to gentle foaming and dispersion in rinse-off products, making it ideal for everyday skincare without heaviness.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Emollient
Softens and smooths skin by filling in surface roughness and improving slip; can also help reduce moisture loss when paired with occlusives and film formers.
Surfactant
Lowers surface tension to enable cleansing, emulsifying, and foaming; central to shampoos, body washes, and many emulsions and micellar systems.
Emulsifying agent
Enables stable mixing of oil and water phases by forming an interfacial film, helping create lotions, creams, and cleansers with consistent texture.

Benefits

Softens skin surface for improved texture and comfort.

Enables stable blending of oils and water in emulsions.

Supports mild cleansing through surface tension reduction.

Who It's For

A quick guide for who this ingredient may suit (and who should be cautious).

Who May Benefit Who Should Avoid
Individuals with dry skin needing softening emollients.
People with allergies to oleic acid or similar fatty esters.
Users of sensitive skin products preferring mild surfactants.
Individuals sensitive to polyglyceryl-based emulsifiers.
Those seeking smooth-textured lotions and cleansers.
Those experiencing irritation from multi-ester surfactants.

Safety Notes

  • Considered safe for cosmetic use with low irritation potential.
  • Non-comedogenic, unlikely to clog pores.
