Potassium Citrate (K₃C₆H₅O₇) is the potassium salt of citric acid. Available primarily as Tripotassium Citrate Monohydrate (CAS 6100-05-6) and Anhydrous (CAS 866-84-2), it manifests as white, hygroscopic crystalline powder or transparent crystals. Exhibiting an assay purity between 99.0% and 101.0%, its strong alkalinity and buffering capacity make it an invaluable chemical agent.
With an exceptional solubility of approximately 154 g/100 mL of water at 20°C, potassium citrate dissolves rapidly without heavy thermal energy input. It serves as an effective sequestrant and chelating agent, binding multivalent metal ions such as Calcium (Ca²⁺) and Magnesium (Mg²⁺) to prevent unwanted precipitation in aqueous systems.
Potassium citrate acts as a highly efficient system buffer, maintaining stable pH levels between 7.5 and 9.0 in dilute solutions. In industrial and beverage formulations, this ionic control inhibits acid-catalyzed breakdown of active ingredients while contributing a clean, mild salty-alkaline taste profile.
Technical Note for Formulators: Unlike Sodium Citrate, Potassium Citrate allows product developers to achieve identical ionic buffering and metal chelation capacity while completely eliminating added sodium content—supporting clean-label "Low Sodium" and "Heart-Healthy" functional market claims.

How Houston’s specialized industries leverage potassium citrate for performance, compliance, and product stability.
In the Greater Houston oil and gas corridor (including the Energy Corridor and Gulf Coast offshore rigs), potassium citrate functions as a high-performance shale stabilizer and fluid density builder. The potassium ions ($K^+$) exchange into clay lattices (such as illite and smectite), reducing hydration swelling and preventing bit balling in High-Temperature/High-Pressure (HTHP) drilling regimes.
Furthermore, its non-corrosive sequestering properties help suppress scale formation ($CaSO_4$ and $CaCO_3$) in completion fluids without degrading sensitive pump machinery or downhole metallurgy.
Houston is home to major regional food processing facilities and beverage co-packers. Potassium citrate is widely utilized as an electrolyte source in sports beverages, nutraceutical shot formulations, and dairy matrix systems. It acts as an emulsifying salt in processed cheese and an acidity regulator in low-calorie jellies, carbonated drinks, and functional fruit juices.
Its high solubility allows seamless blending into automated liquid dosing lines without clogging injection nozzles or altering clear beverage optics.
Adjacent to the Texas Medical Center—the world's largest medical complex—Houston’s pharmaceutical compounders and supplement manufacturers require USP/NF grade Potassium Citrate. It serves as a primary systemic alkalinizer in oral solutions and tablet press matrices targeted at treating renal tubular acidosis and hyperuricosuria (kidney stone prevention).
Direct compression (DC) granular grades are optimized for high-speed tablet presses, ensuring uniform weight variation and mechanical hardness compliance.
Across the petrochemical plants flanking the Houston Ship Channel, industrial steam generation boilers require continuous scale mitigation. Potassium citrate serves as an environmentally benign, biodegradable chelating agent that sequesters heavy metal cations ($Fe^{2+}$, $Cu^{2+}$) and prevents mineral buildup without generating toxic chlorinated residuals in refinery wastewater output.
Understanding regional logistics, port infrastructure, and climate mitigation strategies for raw ingredient procurement.
With global supply chains facing periodic disruptions, sourcing raw potassium citrate through suppliers with bonded warehousing near Bayport and Barbours Cut Container Terminals offers critical operational lead-time advantages. Local stockpiling minimizes transit delays for plants operating on Just-In-Time (JIT) manufacturing schedules across Pasadena, Deer Park, and Baytown.
Houston’s subtropical coastal climate presents high ambient humidity challenges. Technical and USP potassium citrate powders are highly hygroscopic. Forward-thinking manufacturers implement dual-layer polyethylene (PE) moisture-barrier liners and moisture-resistant multi-wall Kraft paper packaging to prevent clumping, caking, and atmospheric degradation during regional storage.
Strict EPA Region 6 and Texas Commission on Environmental Quality (TCEQ) discharge guidelines are pushing Gulf Coast industrial facilities away from synthetic chelators like EDTA and NTA. Potassium citrate is expanding rapidly as a sustainable, fully green alternative that achieves equivalent sequestration constant values while offering complete biodegradability.
Building resilient, quality-backed supply chains for finished-product manufacturers in Texas and worldwide since 2012.

Our technical team provides consultation on particle mesh sizing, solubility limits, moisture control, and taste modulation—helping you select the exact grade before committing to a commercial production run.
Answers to common technical, packaging, and logistics questions from Houston area chemical buyers.
Every shipment includes a lot-specific Certificate of Analysis (COA) confirming assay purity, heavy metals testing, pH, loss on drying, and sieve analysis. Technical data sheets (TDS), Safety Data Sheets (SDS), Kosher/Halal certifications, and allergen/GMO compliance declarations travel with the shipment or are sent electronically prior to delivery.
Standard minimum order quantities begin at single 25 kg bags for pilot batches and formulation trials. Scale-up orders can range from multi-pallet LTL shipments to full truckload (FTL) and full container load (FCL) quantities. Items held in regional US warehouses dispatch within 1 to 3 business days to Greater Houston plants.
Potassium citrate is hygroscopic and prone to caking if exposed to high relative humidity. Store material in its original sealed packaging with double PE inner liners inside a cool, dry warehouse environment (temperature below 25°C / 77°F, humidity below 60%). Pallets should remain shrink-wrapped until active use.
Yes. We offer multiple physical forms including coarse granular (ideal for dust-free oilfield mixing), regular granular, fine powder (20–80 mesh), and micronized DC (Direct Compression) grades specifically engineered for tablet tablet hardness consistency in pharmaceutical manufacturing.
