Description

Acetic acid (CAS 64-19-7 ), commercially recognized as E260 , is the primary organic acid used across food, pharmaceutical, and industrial manufacturing. It functions as an acidulant, pH regulator, preservative, and solvent carrier depending on the application sector. Glacial acetic acid, the concentrated and anhydrous form, is a distinct grade relevant to industrial and synthesis buyers. In food and beverage production, E260 controls pH and acts as a preservative and flavoring agent in condiments, pickles, and sauces. Pharmaceutical manufacturers use it as a buffering agent in formulations and as a reagent or solvent in active ingredient synthesis. In textile and leather processing, it regulates dye bath pH to improve fiber uptake and fixation. Personal care formulators incorporate it into hair rinses and toners where controlled acidity affects cuticle conditioning and product stability. Acetic acid is supplied as a liquid in concentrations typically ranging from 56% to 99.5%. Recognized grades include Food Grade ( FCC ), USP / BP for pharmaceutical use, and technical grade for industrial applications. Bulk supply is standard in IBC containers and road tankers for large scale operations. Smaller drum quantities are available for laboratory and specialty use to ensure flexibility for diverse manufacturing needs. This versatile chemical remains a cornerstone for quality control and chemical synthesis across global supply chains. Contact us for supply of Acetic acid Request Quote
