Description
A colorless, thick, Hygroscopic liquid that is used as a finishing agent for fabrics (Wool, Cotton, rayon, and Silk), tobacco, Leather, sponges, paper products, and Cork. As a finishing agent, diethylene glycol prevents materials from drying out and becoming stiff or hard. Diethylene glycol is used as a Lubricant, Plasticizer, Surfactant, and Solvent in many types of polymers, adhesives, varnishes, paints, inks, and dyes.
