Industrial Chemicals
Citric Acid Anhydrous
Used in drilling fluid pH reduction and cement-contamination treatment, as a polymer stabilizer, and as a key raw material in ion chelation.
Overview
A safer, effective acid for drilling & cementing.
Citric acid is a versatile chemical used across industrial applications, particularly in metal treatment and oilfield operations. It lowers the pH of drilling fluids to ensure their effectiveness, and is used to remove cement contamination from drilling equipment and wellbores — preventing damage and extending the lifespan of drilling systems.
Citric acid also acts as a stabilizer for polymers, helping maintain their integrity and performance, and is a key ingredient in ion chelation processes that remove heavy metals and other impurities from metal surfaces. 414 Solutions is one of the largest importers of citric acid, with product readily available ex-stock in Houston.

Product Benefits
Why customers specify citric acid over other acids.
Safer to Handle
Considered safer to handle than HCl, and safe to handle at drilling rigs.
Effective pH & Iron Control
Reduces pH levels, removes calcium in pre-treatment, and sequesters soluble iron to prevent polymer crosslinking.
Reliable Supply
Of Indian origin and readily available ex-stock in Houston, less reactive and safer than other acids.
Application
Cementing
Removes cement contamination from drilling equipment and wellbores.
Drilling
Reduces pH of drilling fluids for effective, longer-lasting performance.
Ion Chelation
Sequesters soluble iron and removes heavy metals from metal surfaces.
Packaging & Shelf Life
Palletized for standard container loads.
Citric acid is also an environmentally friendly product, making it a responsible choice for industrial applications where sustainability is a consideration.

Gluconic Acid
Gluconic acid (C₆H₁₂O₇) is supplied as a 50% active aqueous solution with a pH between 1.5 – 2.5, produced via fermentation of glucose. It is commonly used as a food additive — a sour-tasting acidulant and flavor enhancer — and as a tenderizer, dough conditioner, pH regulator and preservative in baking and processed foods. Beyond food applications, it is also used in metal treatment and in oil well drilling and completion fluids.
