Pro-xylane Usage And Synthesis

cosmetic ingredient

 Pro-Xylane is a cosmetic ingredient used mainly as an anti-ageing agent in skin creams. Produced by Chimex, its chemical structure is derived from the xylose, a natural component of glycosaminoglycans and of hemicellulose. Pro-Xylane is produced in a two-steps process: 1) The reaction of xylose and acetylacetone in water, then 2) the hydrogenation of the intermediate.

Physical Form

 Powder

Cosmetics Application

 Pro-Xylane is a biochemical which induces neo-synthesis of matrix proteins. It is a biologically active C-glycoside in aqueous media, acts as an activator of glycosaminoglycans (GAGs) biosynthesis. Pro-xylane is the first example of 'Green' chemical used in cosmetic.
Pro-Xylane is an ingredient originally developed by Lancome in 2006. According to research, it is a sugar-protein hybrid made from xylose, a sugar found abundantly in beech trees and known to stimulate the production of glycoaminoglycans (GAGs), molecules responsible for defending the skin against water loss.

function

 Pro-Xylane is a sugar-molecule derived from the beech wood tree utilizing green chemistry. It functions, in vitro, by stimulating the production of proteoglycans, a water-absorbing molecule in human reconstructed skin.

Description

 Pro-xylane (PX) is a cosmetic ingredient used for skin conditioning and is widely used in anti-aging product research. It is considered to be an optimal activator for the biosynthesis of glycosaminoglycans (GAGs) sulphate and can be used to prepare a novel bioactive c-glycoside compound, which is a "green" chemical. In addition, Pro-xylane has been shown to enhance the blue colour of anthocyanins (ACNs), with ACNs-PX showing a colour close to Oxford blue, a surface height of 2.13 ± 0.14 nm and a slight increase in stability[1-2].

Chemical Properties

 Pro-xylane is an organic compound with the appearance of a pale yellow to off-white powder or a colourless viscous liquid, stored in a cool dry place, and has been used in experiments related to the basic science of aging.

Uses

 Pro-Xylane is a sugar-molecule derived from the beech wood tree utilizing green chemistry. It functions, in vitro, by stimulating the production of proteoglycans, a water-absorbing molecule in human reconstructed skin. Higher levels of proteoglycans within the reconstructed skin’s extracellular matrix correlate to increase skin-elasticity and firmness. In cosmetics, pro-xylane products are frequently incorporated into anti-aging lotions and creams to counterbalance signs of aging (i.e., fine lines and wrinkles).

Mechanism of action

 Pro-Xylane enters the skin and stimulates the part that produces and builds the extracellular matrix (a gel-like network of proteins and sugars that act as a scaffold and shock absorber between cells) called proteoglycans.These molecules absorb water and make the matrix more gel-like, increasing the firmness of the cells and increasing the firmness of the skin.It can also serve as a highway to guide supplemental molecules (such as growing proteins) to cells.
