Alpha-Glucan Oligosaccharide
Alpha-Glucan Oligosaccharide is a glucose oligomer with a degree of polymerization ranging from 2 to 10, prepared by the enzymatic action of a Leuconostoc mesenteroides glucosyl transferase on sucrose. The α-D-glucopyranose monomers are linked by (1-2), (1-6), and (1-4) bonds. It is a skin-protecting ingredient obtained by enzymatic synthesis from natural sugars (sucrose and maltose). Its official CosIng functions are listed as cleansing, skin conditioning, and smoothing.
It is claimed to act as a bio-selective substrate that protects and stimulates beneficial microbial skin flora without promoting pathogens or undesirable flora. It also stimulates the release of antimicrobial peptides by keratinocytes (skin cells), supporting the skin's natural defense mechanisms.
