Glyceryl Arachidonate

What is Glyceryl Arachidonate?

Glyceryl arachidonate is a monoacylglycerol ester produced by combining glycerol with arachidonic acid, an essential polyunsaturated omega-6 fatty acid present in certain animal-derived fats and limited plant sources. Chemically, it features a glycerol backbone linked to the arachidonic acid chain, enabling lipid-like behavior in formulations. In cosmetics, it primarily serves in moisturizers, creams, and lotions within the skin conditioning category. As an emollient, it lubricates the skin surface, reducing friction and enhancing spreadability. Simultaneously, its emulsifying action positions amphiphilic molecules at oil-water interfaces, preventing phase separation and ensuring uniform consistency. This dual functionality supports lightweight yet effective hydration delivery without greasiness, making it ideal for everyday skincare products focused on comfort and stability.
