The present invention relates to a method for preparing 3,6-anhydro-L-galactose, and use thereof. More specifically, 3,6-anhydro-L-galactose, which is a monosaccharide constituting agar, is produced in a high yield through chemical and enzymatic methods, and the physiological activities thereof such as whitening, moisturizing, antioxidant, anti-inflammatory activities and the like are displayed, thereby enabling industrial use thereof.

A composition of monoanhydro-hexitol monoalkyl ether isomers bearing an alkyl ether radical (OR) at C-3, C-5 or C-6 of the monoanhydro-hexitol, in which the alkyl group (R) is a linear or branched, cyclic or noncyclic hydrocarbon-based group comprising between 4 to 18 carbon atoms, the process for obtaining such a composition and the use thereof as a nonionic surfactant, emulsifier, lubricant, antimicrobial agent or dispersant.
