Glycolic Acid
Glycolic acid (CAS no: 79-14-1) is a colorless, odorless, and hygroscopic crystalline solid with the chemical formula C2H4O3. The chemical is highly soluble in water, alcohols, acetone, acetic acid and ethyl acetate. It is the smallest alpha-hydroxy acid. The glycolate or glycollate is known as the salt or ester of glycolic acid. People buy glycolic acid which is used as a common ingredient in skin care products.
Production
There are various methods of production of glycolic acid one of which is through chloroacetic acid with sodium hydroxide along with re-acidification. Other method involves the reaction of potassium cyanide with formaldehyde. Then following potassium glycolate is treated with the acid and purified. Glycolic acid in past was synthesized by treating hippuric acid with nitric acid and nitrogen dioxide. The following forms ester of benzoic acid and glycolic acid that is hydrolyzed to glycolic acid by boiling it in sulfuric acid.
Applications
-
Glycolic acid suppliers and manufacturers use in the chemical in textile industry as a dyeing and tanning agent.
-
Food processing industries buy glycolic acid as a preservative and a flavouring agent.
-
Industries like pharmacy buy glycolic acid as skin care agent.
-
Glycolic acid can be utilized on most metal, painted and plastic surfaces without any hurdle of etching or damage. Furthermore, biodegradable glycolic acid is disposable than other cleaning agents such as hydrochloric or phosphoric acid.
-
Oil field and petro refining industries buy glycolic acid to effectively eliminate harmful deposits by minimizing corrosion damage of steel or copper piping systems and all with safety in handling and ease of use.
Toxicity
Intense doses of glycolic acid on skin or eyes can lead to effects that are typical of a strong acid for example dermal and eye irritation. Glycolic acid's renal toxicity is because to its metabolism to oxalic acid. Glycolic and oxalic acid, along with excess lactic acid, are accountable for the anion gap metabolic acidosis.
Safety
Below are some of precautions that must be taken glycolic acid suppliers and manufacturers:
-
Eye Contact: Rinse right away using plenty of water, and wash under the eyelids, for as a minimum of 15 minutes. Seek for immediate medical attention as required. Continue to open eye wide while rinsing.

-
Ingestion: Look for immediate medical attention as per the requirement. Do not encourage vomiting. Try to drink plenty of water. Do not give anything by mouth to the unconscious person.
Storage and Handling
While handling glycolic acid use personal protective equipment. Operate only under a chemical fume hood. Store the containers firmly closed in a dry, cool and well-ventilated place. Try not to store in metal containers, as glycolic acid is best reserved in a plastic or glass bottles.
