There is a need to modify many cosmetic or pharmaceutical products so that their properties (bioavailibility, toxicity, liposolubility, and hydrosolubility) are optimized. This can be achieved through transportation by “carrier molecules” which can promote drug intake. The amphiphilic structure of α-butylglucoside makes it particularly efficient for such a purpose. α-Butylglucoside is produced on an industrial scale through enzymatic transglycosylation between maltose and butanol (1-3). This glucose derivative contains several reactive hydroxyl groups and can, therefore, be acylated by means of lipase-catalyzed reactions (4). The advantage of α-butylglucoside over glucose is that the butanol moiety of α-butylglucoside helps the molecule to dissolve in apolar media, which are usually recommended for optimal lipase activity and stability (5-7).
