Glycerol Monocaprylate Glyceryl Monocaprylate 1-Caprylyl Glycerol Monocaprylin
Compatibility
Works well with:
Phenoxyethanol Ethylhexylglycerin Glycerin Caprylic/Capric Triglyceride Sodium Benzoate
Glyceryl Caprylate is commonly paired with phenoxyethanol or ethylhexylglycerin to create a broad-spectrum preservative system with synergistic efficacy. It is generally compatible with most cosmetic ingredients but may exhibit reduced antimicrobial activity at higher pH levels above 7. At elevated concentrations it can increase surfactant irritation potential, so formulation balance is recommended.
Formulation notes
Glyceryl Caprylate is a monoester of glycerin and caprylic acid (C8 fatty acid) that serves primarily as a skin-conditioning emollient while also providing meaningful antimicrobial activity, particularly against gram-positive bacteria and yeasts. Formulators use it as a multifunctional ingredient to boost preservation systems, reduce reliance on traditional preservatives, and impart a light, non-greasy skin feel. It is considered mild and well-tolerated, making it a popular choice in clean-beauty and natural-positioned formulations.
