Because of its small molecular weight and size, it has a better capability to penetrate skin. It can diminish the skin and make skin look younger by acting as a humectants to absorb moisture in air by exfoliating action to break the bonds between dead skin cells. Attribute: 70% glycolic acid Low odor, high water solubility, no flammability, biodegradability; efficient neutralization, compatibility with many cleaning additives. Stability and Storage of 70% glycolic acid: It is stable stored at temperatures above 10¡ãC (50¡ãF). The storage area should be kept warm to maintain temperatures above 10¡ãC (50¡ãF) to prevent precipitation of glycolic acid crystals.

As well as an agent for nickel plate. They are also used in emulsion polymers, solvents and ink and paint additive to improve flow properties and impart gloss. Solubility: Freely soluble in water, methanol, ethanol, acetone, acetic acid and ethyl acetate; slightly soluble in ethyl ether, but hardly soluble in hydrocarbon s olvents. Attribute: Low odor, high water solubility, no flammability, biodegradability; efficient neutralization, compatibility with many cleaning additives. Stability and Storage: It is chemically stable to 50¡ãC (122¡ãF). Polymerization occurs above 50¡ãC (122¡ãF).
