Science
Mechanism of Action
As an ester of Eicosapentaenoic Acid (EPA), Glyceryl Eicosapentaenoate primarily acts through its EPA component. EPA, an omega-3 polyunsaturated fatty acid, modulates cell membrane properties, significantly reducing the synthesis of pro-inflammatory eicosanoids such as prostaglandins and leukotrienes. Concurrently, it stimulates the generation of specialized pro-resolving mediators, which collectively help to alleviate inflammatory skin conditions, reduce redness, and reinforce the skin's immune response. Furthermore, EPA contributes to maintaining the skin barrier's integrity, thereby preventing moisture loss and promoting optimal skin hydration. The glyceryl ester portion inherently provides emollient benefits, softening and smoothing the skin by creating a protective film that minimizes transepidermal water loss. Depending on its specific mono-, di-, or tri-esterification, it may also contribute to formulation stability as an emulsifier.

Stability
Specific stability data for Glyceryl Eicosapentaenoate are not extensively documented. Generally, glycerol esters can function as emulsifiers and contribute to the stability of cosmetic formulations. However, it is noteworthy that 1,2,3-Trieicosapentaenoyl Glycerol, a related triglyceride, is identified as a highly flammable liquid and vapor.
Safety
Safety Profile
Glyceryl Eicosapentaenoate, as a specific INCI name, has not been individually reviewed by the Cosmetic Ingredient Review (CIR) Expert Panel or the SCCS. However, the CIR has broadly assessed 'Glyceryl Monoesters,' concluding that most are safe for cosmetic use within current practices, with Glyceryl Arachidonate being an exception due to insufficient data. The CIR also deemed 'Triglycerides,' including 22 additional glyceryl triesters, safe as used in cosmetics. It is important to distinguish this ingredient from 'Glyceryl Trieicosapentaenoate' (a triglyceride of EPA), for which a Safety Data Sheet indicates hazards such as being a highly flammable liquid and vapor and causing serious eye irritation; this specific information pertains to a raw material designated 'for research use - Not for human or veterinary diagnostic or therapeutic use'.

Verdict
Glyceryl Eicosapentaenoate is a valuable ingredient, leveraging the known anti-inflammatory and barrier-supporting properties of EPA, along with its inherent emollient function, despite the absence of direct clinical studies on this specific ester.
