Polyglyceryl-2 Sesquioleate

What is Polyglyceryl-2 Sesquioleate?

Polyglyceryl-2 Sesquioleate is a non-ionic emulsifier formed by esterifying polyglycerol-2, derived from natural glycerol, with oleic acid sourced from vegetable oils such as sunflower or olive. This creates a versatile ingredient primarily used in oil-in-water emulsions like lotions, creams, and cleansing products. It functions by positioning itself at the oil-water interface, reducing surface tension to prevent phase separation and ensure uniform texture. Additionally, it acts as a co-surfactant to enhance foam and rinse-off properties in washes, while providing emollient effects that smooth skin roughness and aid in moisture barrier support. Valued for its PEG-free profile, it suits formulations aiming for mildness and stability across various skincare categories.

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

Provides emollient action to soften and smooth skin texture.

Stabilizes oil-water mixtures for consistent product feel.

Assists in mild surfactant activity for effective yet gentle cleansing.

Who It's For

Who May Benefit Who Should Avoid
Individuals seeking smooth, non-greasy emollient effects in daily moisturizers.
Those with rare allergies to oleic acid or glycerol derivatives.
Users of emulsion-based products like lotions needing reliable stability.
People sensitive to ester-based emulsifiers in patch tests.
People preferring gentle, plant-sourced surfactants in cleansers.
Individuals avoiding multi-functional surfactants in minimalist routines.

Safety Notes

  • Considered low hazard in cosmetic safety assessments.
  • Typically shows minimal irritation potential in formulation use.
