Natural chemical product. CAS 22160-26-5. Formula C9H18O8. MW 254.2. Enzymatically processed from natural succrose and glycerine. Glucosylglycerol belongs to the class of compatible solutes osmolytes. It is a non-toxic, non-irritating protective osmolyte responsible for the osmotic adaptation of blue-green algae, rhizobacteria and Pseudomonas and also found in the drought-resistant resurrection plant Myrothamnus flabellifolia. Glucosylglycerol protects its host against osmotic stress, heat, desiccation and UV. Glucosylglycerol is an animal free and protein-free low molecular weight stabilizer which is an excellent cryoprotector for proteins in vitro, especially antibodies. In vitro models and skin models demonstrate strong activity of glucosylglycerol on aged and stressed skin cells with rejuvenating, recovering and radical scavenging properties.
