Polyglyceryl-10 Dipalmitate

What is Polyglyceryl-10 Dipalmitate?

Polyglyceryl-10 Dipalmitate forms through esterification of polyglycerol-10—a polymer chain of ten glycerol units from vegetable sources—with two molecules of palmitic acid, a saturated fatty acid typically sourced from palm kernel oil. This creates a hydrophilic-lipophilic balanced compound suited for cosmetics like moisturizers, lotions, and mild cleansers. It functions primarily by positioning at oil-water interfaces, forming protective films that prevent phase separation and yield uniform textures. Its emollient nature allows it to deposit a light lipid layer on skin, enhancing slip and mimicking natural sebum for a smoother feel. As a surfactant, it reduces interfacial tension to support dispersion and gentle removal of impurities in formulations.

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 by depositing a light emollient layer for improved texture.

Stabilizes oil-in-water emulsions for consistent lotion and cream consistencies.

Enables mild surfactant action in cleansers without compromising skin comfort.

Who It's For

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

Who May Benefit Who Should Avoid
Users of daily moisturizers needing stable, non-separating formulas.
Those with rare sensitivities to palm kernel-derived fatty acids.
Individuals preferring gentle, plant-sourced emulsifiers in routines.
People opting for surfactant-free products entirely.
People seeking emollients to enhance skin smoothness in leave-on products.
Individuals avoiding multi-functional esters in formulations.

Safety Notes

  • Expert reviews deem it safe in typical cosmetic concentrations.
  • Presents low comedogenic risk, unlikely to contribute to pore blockage.
