What Is Polyglyceryl-20 Hexacaprylate?

Polyglyceryl-20 hexacaprylate is a synthetic surfactant—a molecule with both water-loving and oil-loving properties. It belongs to the polyglyceryl ester family and is commonly used in cosmetic formulations to help combine ingredients that would otherwise separate, such as oils and water-based actives.

As a solubiliser, it allows formulators to create stable, elegant products where diverse ingredients can coexist. It does not directly treat skin conditions but instead serves a functional role in keeping your skincare products homogeneous and effective.

How It Works

Polyglyceryl-20 hexacaprylate works by positioning itself at the boundary between oil and water molecules. One end of the molecule attracts oils, whilst the other attracts water, allowing these normally incompatible substances to mix and remain stable.

This means formulators can create products containing beneficial oils alongside hydrating or treatment-focused water-based ingredients without them separating over time. The result is a more elegant, uniform product that delivers its actives consistently.

Clinical Evidence & References

Research on polyglyceryl-20 hexacaprylate specifically is limited in published literature. Most evidence comes from cosmetic chemistry and stability studies rather than clinical trials on skin outcomes.

However, as a solubiliser and emulsifier, it plays an important role in formulation science, allowing skincare products to maintain their integrity and deliver their active ingredients effectively. Its safety profile in cosmetics is well-established, though individual response depends on the overall formulation and your skin's sensitivity.

How to Use

As this ingredient is a formulation component rather than an active treatment, there are no specific usage instructions. Simply use your product as directed by its brand. The presence of polyglyceryl-20 hexacaprylate ensures the formula remains stable and effective throughout its shelf life.

Safety & Precautions

Polyglyceryl-20 hexacaprylate is generally well-tolerated and regarded as safe for use in cosmetics. It is not a known sensitiser, though as with any ingredient, individual sensitivities can occur.
