Alpha-glucan Oligosaccharide

Updated

Alpha-Glucan Oligosaccharide is a glucose oligomer exhibiting a degree of polymerization ranging from 2 to 10. It is prepared by the 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.

Purpose

This natural prebiotic helps reinforce and support a healthy microbiome while helping skin become less likely to show signs of irritation.

Article

Alpha-glucan oligosaccharide is a natural prebiotic that helps support a healthy microbiome. When skin’s microbiome (it’s invisible barrier) is disrupted, the population of harmful bacteria can grow since it’s not being kept in check by healthy flora on the surface. This has the potential to trigger signs of irritation and sensitized skin.

Alpha and beta-glucan oligosaccharides also have antioxidant benefit, helping to reduce the visible effects of oxidative stress on skin.

Recommended usage levels of alpha-glucan oligosaccharide in skin care range from 0.25–3% on its own and 0.5–3% when part of a blend with other prebiotics.
