Aloe barbadensis leaf extract is the powder obtained from the freeze-dried gel of the leaves of the aloe vera plant, Aloe barbadensis.
For centuries, the plant aloe vera has been used by cultures for its beneficial effects on human health 1. Today aloe vera gel continues to be used in supplements, foods, beverages, and cosmetics. Aloe leaves consist of two major parts, the outer leaf epidermis and the inner leaf gel, which are very different in their chemical composition and properties. Aloe gel is obtained from the inner portion of the leaves. Aloe gel is rich in nutrients and contains an abundant supply of glycoproteins and mono-, oligo- and polysaccharides. Monosaccharide constituents include glucose, mannose, galacturonic acid, glucuronic acid, galactose, arabinose, fucose, glucosamine, fructose, rhamnose and xylose 2.
Much of the health benefits observed by the use of aloe vera gel may be attributed to its high molecular weight polysaccharides. Before a process was developed to stabilize aloe vera gel or extracts, fresh preparations were regarded as being required for any therapeutic efficacy 3. It has now been shown that careful drying of aloe vera gel can retain the polysaccharide content important for producing many of its health benefits 4.
Today aloe vera gel continues to be used in cosmetics and personal care products as a skin conditioning agent, which acts both to lubricate the skin surface and to increase water content of the top layers of the skin by drawing moisture from the surrounding air 5. According to the Cosmetic Ingredients Review (an independent committee established by the Personal Care Products Council, an industry trade association that thoroughly reviews and assesses the safety of ingredients used in cosmetics), Aloe barbadensis leaf extractis safe to use in the amounts present in our products 6.
