Description for Glycolic Acid : Glycolic Acid (The Eco-friendly and most Versatile Acid)
Product Overview :
Glycolic Acid has a unique combination of properties that makes it valuable in a wide variety of end-uses, especially when de-scaling is needed :
Market Applications :
Industrial Cleaners :
Dairy Cleaning : The unique combinations of glycolic acid's properties make it an excellent acid cleaner for removing milk stone, casein and other deposits from dairy processing equipment. Glycolic acid dissolves and complexes hard water scale more effectively than phosphoric acid. Waste materials and any un-reacted acid are easily washed away with a final rinse of potable water.
Food Processing Equipment Cleaning : The use of glycolic acid in the cleaning of meat, poultry and egg products processing equipment, providing these food contact surfaces are rinsed with potable water after cleaning.
Transportation Cleaning : Because of its low toxicity, glycolic acid is the ideal replacement of more toxic acids such as oxalic, which is commonly used in the cleaning of stainless steel and aluminum, rail cars, as well as truck bodies, "Mag" wheels. Glycolic acid's low corrosiveness, good salt solubility and high rinsability, low odor and ready biodegradability contribute to its attractiveness in these applications.
Masonry : Glycolic acid can be used alone or in mixtures with other acids, particularly phosphoric acid, to produce an effective cleaner for bricks and concrete. Some clay used in making white bricks contain traces of metals that cause staining as they migrate to the surface during kiln firing. Glycolic acid's complexing ability affords effective removal of these metals.
Paper Maker Felt Cleaning : Because of its ability to complex aluminum salts, as well as other hard water salts, glycolic acid can be valuable in conditioning papermaker felts. It is non-damaging to the nylon components of these paper felts.
Water Treatments :
Water Well Cleaning : Glycolic acid complexes and removes accumulated iron and carbonate deposits in water wells. Glycolic acid removes the scale which suppresses the flow of water. In addition, anecdotal and technical literature reports indicate that such treatment is particularly effective where flow is suppressed due to the presence of slime and iron metabolizing bacteria. Glycolic acid is easily handled because of its liquid form, low corrosiveness and lack of fumes. It also has no solubilization problems. Waste disposal from well cleaning is facilitated by glycolic acid's ready biodegradability and its ability to prevent salt precipitation even as the pH is increased. Glycolic acid does not replace the need for phosphate treatment used to aid clay removal.
Metal Processing :
Copper Brightening : Glycolic acid can be used to give luster to copper and copper alloys, following normal pickling operations. This luster has been found to be retained much longer than when strong oxidizing acids are used. Polishes for copper utensils, like pots and pans, can also be formulated with glycolic acid as the primary active ingredient.
Electroplating/Electroless Nickel Plating : Glycolic acid is used in numerous electroplating applications. The sodium and potassium salts of the acid are excellent substitutes for Rochelle salts used in bath additives. Because glycolic acid forms complexes with virtually all multivalent metals, its salts can be used in aluminum, chrome, lead, cobalt, tin, and nickel electroplating baths. Glycolic acid can also be used to clean and condition substrates prior to electroless plating. The sodium salt of glycolic acid can be used for nickel electroless plating.
Electropolishing : Glycolic acid, usually in combination with phosphoric acid and/or sulfuric acid, may be used in the electropolishing of stainless steel. The mixture provides a bath with long life and reduced sludging characteristics.
Leather Industry : Glycolic acid has several applications in the leather industry. It can be used to replace formic acid in leather dyeing and in combination with stronger mineral acids to improve deliming. Glycolic acid has been observed to improve the grain of leathers by reducing fine lines and wrinkles in the hides. It can be used to adjust the pH in tanning and dye baths. The sodium salt of glycolic acid can be used as a masking agent. Tris-(hydroxyacetato)-chromate, a glycolic acid chromium compound, has been used to improve chrome tanning.
Textile Dyeing and Finishing : Due to its negligible volatility and low odor glycolic acid is a good replacement for other organic acids, such as acetic acid, in textile dyeing and finishing applications. The complexing ability of glycolic acid is of benefit in managing metal ions present in the bath water, rinses, etc. It is used for dyeing chrome colors, but is not recommended for colors that are easily reduced. It is a good substitute for cream-of-tartar in mordanting wool with chrome, because it combines good exhaustion with good reduction. Glycolic acid can also be used as a solvent in liquid cationic dye products and to dissolve solid cationic dyes.
Laundry Sour : As a laundry sour, glycolic acid's liquid form and high solubility in water make it ideal for automatic liquid-dispensing laundry equipment. Because it does not buffer, the addition of glycolic acid can be directly controlled by pH. Its excellent rinsability minimizes the amount of acid retained by the fabrics, thereby reducing the mechanical and chemical damage that can occur with silicafluoride salts. Because glycolic acid is readily biodegradable, waste disposal is easy.
Oil and Gas Well Applications : Acid Well Stimulation - Acidizing Glycolic Acid alone or in combination with other acids like hydrochloric or hydrofluoric is injected into the formation, dissolving a portion of rock and creating a large pore structure in the formation, thus increasing the flow of oil. Glycolic acid is used in conjunction with hydrochloric or sulfamic acids to prevent iron precipitation in cleaning operations or in water flooding.

Chemical and Physical Stability :
Precautions in Use : As a moderately strong acid, glycolic acid will react in a typical fashion with carbonates to release carbon dioxide gas; with cyanide salts to release hydrogen cyanide; with sulfide salts to release hydrogen sulfide and with active chlorine compounds (like chlorine bleach) to release chlorine. It will also react with active metals (like sodium) to release hydrogen. Glycolic acid has typical reactions with strong oxidizing agents like nitric acid, to form intermediate compounds like glyoxylic acid, oxalic acid and (ultimately) carbon dioxide.
