Glyceryl caprylate
Glyceryl caprylate is the monoester of glycerin and caprylic (octanoic) acid, made by esterifying glycerin with caprylic acid from coconut or palm kernel oil, or by glycerolysis, and often purified by distillation to raise the monoester content. In cosmetics it is used as an emollient and co-emulsifier and in multifunctional blends used alongside preservatives. Brands buy it as a clear liquid or soft solid, either alone or blended with other glyceryl esters.
Suppliers sell different products under the same name. Specify the one you need.
High-monoester grades made by molecular distillation, usually a soft solid or liquid depending on temperature.
Mixtures of mono-, di- and triglycerides with a stated monoester minimum.
Combined with glyceryl undecylenate, glyceryl caprate or other esters as ready-made multifunctional blends.
Made from plant-derived caprylic acid and glycerin, sometimes with COSMOS or Ecocert approval.
Compare each result with your own specification when the lot arrives.
Store glyceryl caprylate in closed containers in a cool, dry place; it may solidify or separate in cool weather and should be gently warmed and mixed before sampling. Protect from moisture, which can hydrolyze the ester over time. Shelf life and retest dates follow the supplier's specification.
Record monoester content and acid value for each lot, since these change emulsion behavior and odor. Homogenize partly solid drums before taking material, and rotate stock first-in, first-out.

Suppliers are in alphabetical order and none pays to appear. Each claim is checked against the supplier’s own website on the date shown. Ask for the specification sheet and a recent COA before you order, and confirm details with the supplier.
Common forms include distilled monoester, standard grade, blends and natural-origin grades. Ask each supplier for the specification sheet of the exact grade they quote.
