Polyglyceryl-6 Caprylate

What is Polyglyceryl-6 Caprylate?

Polyglyceryl-6 caprylate is a multifunctional ingredient formed by esterifying polyglycerol-6, a chain of six glycerol molecules derived from vegetable glycerin, with caprylic acid, a saturated medium-chain fatty acid typically sourced from coconut or palm kernel oil. This creates a non-ionic surfactant suitable for natural and eco-friendly cosmetics. It works primarily in cleansing products, lotions, and creams by lowering surface tension between oil and water phases, enabling stable emulsions with smooth textures. As an emollient, it mimics skin's natural lipids to enhance product spreadability and provide a soft after-feel. Commonly featured in micellar waters, gentle facial cleansers, and body washes, it serves as a polyethylene glycol-free alternative, supporting clear, homogeneous formulations without compromising mildness.

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

Enhances skin softness by filling surface imperfections and improving product glide.

Facilitates effective yet gentle cleansing through reduced surface tension.

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

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 preferring natural, PEG-free surfactants in daily cleansers.
Those with known allergies to coconut or palm-derived fatty acids.
People with dry skin seeking added emolliency in moisturizers.
People sensitive to polyglycerol esters, though rare.
Users of sensitive skin formulas needing mild emulsifiers.
Individuals preferring completely anhydrous products.

Safety Notes

  • Considered safe for cosmetic use by regulatory bodies like the Cosmetic Ingredient Review.
  • Low comedogenic potential, unlikely to clog pores.
