    Usage:
    1. glycolic acid and its derivatives are used commercially in leather tanning and textile dyeing.
    2. as a flavouring agent and preservative in food processing, water treatment industries;
    3. pH control; and chemical intermediates as well as in household, industrial, electronics cleaning applications and cosmetics.
    4. Glycolic acid also used in emulsion polymers, solvents and ink and paint additive to improve flow properties and impart gloss.
    5. Glycolic acid is used extensively in cosmetics. It is known that it diminishes the lines on the skin and make skins look young by acting as a humectant to absorb moisture in air and by exfoliating action to break the bonds between dead skin cells.
    6. glycolic acid has the property to form metal complexes and can be used in cleaning applications and hard water dissolution.
    7. Glycolic acid is an useful intermediate in organic synthesis including oxidation/reduction, esterification and formation of oligomers as well as long chain polymerization.

    Package: 25kgs/drum (crystal); 250kgs/ metal pail (liquid)
