Description

Argil, Argol is a natural, complex mixture of potassium bitartrate and other organic acids derived from grapes. This versatile compound serves as a crucial source of tartaric acid and its salts, valued for its natural origin and functional properties. It is essential for manufacturers in the food & beverage, pharmaceutical, and chemical synthesis industries seeking a reliable, high-purity raw material.

Application

• Food & Beverage Industry: Primarily used as a natural acidulant, pH control agent, and leavening acid in baking powders. It is a key ingredient in cream of tartar.
• Pharmaceutical Excipient: Employed as a tartrate source in various medicinal preparations and as a chiral resolving agent in the synthesis of active pharmaceutical ingredients (APIs).
• Chemical Synthesis: Acts as a precursor for the industrial production of tartaric acid, potassium sodium tartrate (Rochelle salt), and other tartrate esters used in specialized applications.
• Electroplating & Metal Treatment: Functions as a complexing agent in electroplating baths and in metal cleaning and polishing formulations.
• Textile Dyeing: Serves as a mordant to fix dyes onto fabrics, particularly in natural dyeing processes.
• Laboratory Reagent: Used in analytical chemistry and as a component in microbiological culture media.

Quality Control

We supply Argil, Argol in various grades, including Technical and Food Grade (FCC), to meet diverse industrial requirements. Our products undergo rigorous quality testing to ensure compliance with industry standards. Key parameters such as tartaric acid content, purity, and impurity profiles are strictly monitored. Certificates of Analysis (COA) are available upon request to guarantee batch-to-batch consistency and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent caking and degradation from atmospheric moisture.
