What Is PEG-7 Caprylic/Capric Glycerides?
PEG-7 Caprylic/Capric Glycerides is a synthetic emulsifier derived from caprylic and capric acids (medium-chain fatty acids) combined with polyethylene glycol (PEG). It belongs to a class of solubilising agents used in cosmetic formulations to help oil and water components mix smoothly, preventing separation.
In skincare products, it works behind the scenes to create stable, homogeneous textures and improve the spreadability of formulations. It is not an active ingredient targeting specific skin concerns, but rather a functional ingredient that enables other actives to be delivered effectively.
How It Works
PEG-7 Caprylic/Capric Glycerides is an emulsifier with both lipophilic (oil-loving) and hydrophilic (water-loving) properties. This dual nature allows it to surround oil droplets and disperse them throughout a water-based formula, or vice versa, creating a stable suspension rather than separation.
By doing this, it ensures that all components of a skincare product remain evenly mixed, which is essential for consistent texture, ease of application, and uniform distribution of active ingredients across the skin.
Clinical Evidence & References
PEG-7 Caprylic/Capric Glycerides is a well-established cosmetic ingredient with a long history of safe use. It is not an active ingredient, so clinical studies do not typically measure direct effects on skin concerns. Instead, its role is functional: stabilising formulations and facilitating the delivery of other active ingredients.
Regulatory bodies including the European Commission and the Cosmetic Ingredient Review (CIR) panel consider it safe for use in cosmetics at typical concentrations. No significant adverse effects have been associated with this ingredient in cosmetic applications.
How to Use
There are no special usage instructions for this ingredient, as it functions within the formulation itself rather than being a targeted active. Simply use your product as directed on the label. Its presence ensures the formula remains stable and blended throughout the product's shelf life.
