The CIR Expert Panel assessed the safety of 6 Cucumis sativus (cucumber)-derived ingredients and found them safe in cosmetic formulations in the present practices of use and concentration. These ingredients are reported to function in cosmetics as skin-conditioning agents. Cucumber is a commonly consumed food with no history of significant adverse effects, suggesting that its ingredients should not pose any major safety issues following oral exposure. This assessment focused on the dermal exposure to the low concentrations of these ingredients as used in cosmetics. Some of the constituents of cucumbers have been assessed previously for safe use as cosmetic ingredients.

Safety Assessment of Cucumis sativus (Cucumber)-Derived Ingredients as Used in Cosmetics.

Glyceride composition of the seed fat ofMomordica charantia has been determined by gas liquid chromatography (GLC) of oxidized esterifield glycerides. Stearodiunsaturated glycerides form ca. 80% of the total glycerides. Values obtained by the above method agree closely with those obtained by Youngs' (8) method. However, there is a wide variation between the present results and those calculated according to Vander-Wal (5) from lipase hydrolysis data. Possible reasons for this anomalous glyceride pattern are discussed.

Folgende ungesattigte Glyceride werden synthetisiert: 1-Stearo-2,3-di-α-elaeostearin, Tri-α-elaeostearin, 1,2-Dioleo-3-α-elaeostearin, 1-Oleo-2,3-di-α-elaeostearin, 1,2-Dilinolo-3-α-elaeostearin und 1-Linolo-2,3-di-α-elaeostearin. Die Darstellung erfolgt durch Umsetzung der entsprechenden 1-Monoglyceride mit den betreffenden Fettsaurechloriden. Von den so erhaltenen Glyceriden wird die Sauerstoff-Aufnahme mit Hilfe eines Filmografen messend verfolgt, die erhaltenen Kurven werden diskutiert und die Verfilmungseigenschaften der neuen Glyceride untersucht.



Synthesis of Pure Glycerides of Elaeostearic Acid and their Behaviour during Autoxidation



The following unsaturated glycerides were synthesized: 1-stearo-2,3-di-α-elaeostearin, tri-α-elaeostearin, 1,2-dioleo-3-α-elaeostearin, 1-oleo-2,3-di-α-elaeostearin, 1,2-dilinolo-3-α-elaeostearin and 1-linolo-2,3-di-α-elaeostearin. The synthesis was achieved through the reaction of the 1-monoglyceride with the relevant fatty acid chlorides. These synthetic glycerides were subsequently subjected to autoxidation. Amount of oxygen required for their autoxidation was followed with the help of a filmograph and the curves, obtained thereby are discussed. The film forming properties of these pure glycerides were investigated.
