Caprylic/Capric Triglyceride PEG-4 Esters
What is Caprylic/Capric Triglyceride PEG-4 Esters?
Caprylic/Capric Triglyceride PEG-4 Esters is a polyethylene glycol ester derived from caprylic and capric fatty acids sourced from coconut or palm kernel oil, functioning as an emollient, emulsifier, and surfactant in skincare formulations. It provides a non-greasy, lightweight texture, enhances product spreadability, and helps stabilize emulsions by reducing surface tension. This ingredient is commonly used in creams, lotions, and makeup products to improve skin feel and solubility of other ingredients.
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.
Emulsifying agent
Enables stable mixing of oil and water phases by forming an interfacial film, helping create lotions, creams, and cleansers with consistent texture.
Skin conditioning agent
Maintains skin softness, smoothness, and flexibility.
Viscosity controlling agent
Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.
