Access for institutions in China If your institution has a subscription to this article, you can read it here. The safety of 43 glyceryl monoesters listed as cosmetic ingredients was reviewed in a safety assessment completed in Additional safety test data pertaining to Glyceryl Rosinate and Glyceryl Hydrogenated Rosinate were received and served as the basis for this amended report. The following 20 glyceryl monoesters are currently reported to be used in cosmetics: Glyceryl Monoesters are not pure monoesters, but are mostly mixtures with mono-, di-, and tri-esters.
Glyceryl Monoesters monoglycerides are metabolized to free fatty acids and glycerol, both of which are available for the resynthesis of triglycerides. Glyceryl Laurate enhanced the penetration of drugs through cadaverous skin and hairless rat skin in vitro and has been described as having a wide spectrum of antimicrobial activity.
Glyceryl monoesters have little acute or short-term toxicity in animals, and no toxicity was noted following chronic administration of a mixture consisting mostly of glyceryl di- and mono- esters. Glyceryl Laurate did have strong hemolytic activity in an in vitro assay using sheep erythrocytes.
Undiluted glyceryl monoesters may produce minor skin irritation, especially in abraded skin, but in general these ingredients are not irritating at concentrations used in cosmetics. Glyceryl monoesters are not sensitizers, except that Glyceryl Rosinate and Hydrogenated Glyceryl Rosinate may contain residual rosin, which can cause allergic reactions.
These ingredients are not photosensitizers. Glyceryl Laurate exhibited antitumor activity and Glyceryl Stearate was negative in a tumor promotion assay.
At concentrations higher than used in cosmetics, Glyceryl Laurate did cause moderate erythema in human repeat-insult patch test RIPT studies, but the other glyceryl monoesters tested failed to produce any significant positive reactions. It was reasoned that the available data do support the safety of this use because there would be minimal contact with the skin and no occlusion. The safety of Arachidonic Acid was not documented and substantiated for cosmetic product use in an earlier safety assessment and those same safety questions apply to Glyceryl Arachidonate.
Based on these data, the Cosmetic Ingredient Review CIR Expert Panel found that these glyceryl monoesters are safe as cosmetic ingredients in the present practices of use and concentration: Additional data needed to support the safety of Glyceryl Arachidonate include 1 dermal absorption data; and, based on the results of the absorption studies, there may be a need for 2 immunomodula-tory data; 3 carcinogenicity and photocarcinogenicity data; and 4 human irritation, sensitization, and photosensitization data.
