Xylitylglucoside
Xylitylglucoside is a plant-derived sugar compound formed from glucose and xylitol, and serves as the main component of the moisturizing complex known as Aquaxyl. It functions as a humectant and skin conditioning agent according to its official CosIng listing. It is typically used as part of the Aquaxyl complex, which also includes anhydroxylitol and xylitol.
As part of the Aquaxyl complex (at 3%), xylitylglucoside is reported to increase water content in the outer skin layer both immediately and long-term, improve the appearance of cracked and dry skin, and support the skin barrier by promoting lipid (ceramides and cholesterol) and protein synthesis. A comparative study published in the Journal of Cosmetic Dermatology found that 4% Aquaxyl performed comparably to urea as a humectant in a hydrogel formula.
