Triclosan BP EP USP Pharma Grade stands out as a high-purity, specialty chemical used in pharmaceutical and personal care applications. Its chemical composition—C12H7Cl3O2—marks it as a chlorinated aromatic compound. Each molecule consists of two phenolic rings bonded together with three chlorine atoms, a structure giving Triclosan its antimicrobial punch. The pharma grade rating means this material aligns with British Pharmacopoeia (BP), European Pharmacopeia (EP), and United States Pharmacopeia (USP) standards. Those references ensure heightened purity and tight batch-by-batch controls.
Triclosan appears as a white to off-white crystalline powder, sometimes described by suppliers as manifesting in flakes, tiny pearls, or dense, free-flowing solids. This powder resists easy dissolution in water but dissolves well in organic solvents like ethanol. A dense chemical, it clocks in with a specific gravity around 1.49. The melting point sits near 56°C, providing a clear physical boundary between its solid and liquid forms. Unlike some raw materials that might clump or degrade quickly, Triclosan’s crystalline structure preserves stability under standard storage conditions—cool, dry, and shielded from strong light. Practically, its solid state allows for careful, dust-minimizing handling, relevant in pharmaceutical or personal care labs.
The molecular formula C12H7Cl3O2 encapsulates the atomic arrangement: twelve carbons, seven hydrogens, three chlorines, and two oxygens. The two aromatic rings in its core drive both effectiveness and interactions with bacteria, as these rings disrupt the enzymes crucial to microbial growth. Chlorine substitutions on the ring intensify its antimicrobial activity. Triclosan does not dissolve fully in water, so pharmaceutical scientists typically suspend or solubilize it in alcohol-based systems. The strong molecular backbone resists breakdown under typical manufacturing conditions, contributing to chemical consistency and ease of formulation.
For global trade, Triclosan holds an HS Code of 2908.11, which categorizes it among halogenated, phenolic chemicals under the Harmonized System. Industry specifications put the material’s purity above 99%. Impurities get flagged in rigorous testing—UV absorbance, loss on drying, ash residue, and known trace contaminants, each measured against international pharmacopeia cut-offs. These blocks of specification govern the raw material’s acceptance in regulated sectors, including pharmaceuticals and top-tier cosmetics. Such steadfast enforcement of specification helps workers and end-users trust the quality in every shipment.
Manufacturers process Triclosan to maximize usability across different industries. As a powder, it mixes into bulk raw material blends. Flakes and pearls serve the needs of large-scale production, where dust suppression and easy dosing matter in industrial processes. Each physical presentation keeps Triclosan stable—neither hygroscopic nor prone to caking—so factories avoid flow disruptions or inconsistent formulation. Whether used in small research batches or scaled manufacturing, the material stays robust, demonstrating why solid forms remain preferred for both safety and practicality.
As with many halogenated organics, proper handling and safety protocols around Triclosan deserve close attention. Inhalation of dust and direct skin contact must be minimized. It is classified as harmful if swallowed or inhaled in appreciable quantities. General guidance says gloves, dust masks, and protective eyewear keep exposure in check; labs and production floors with experience in fine chemicals carry these precautions as standard routines. Triclosan shows low acute toxicity for humans under controlled exposure, but evidence links high, prolonged environmental concentration to aquatic toxicity and possible bioaccumulation. Numerous regulatory bodies, including the US FDA and European Chemicals Agency, monitor and occasionally restrict Triclosan’s use in specific product types based on emerging data around health and environmental safety. Effective containment, waste management, and substitution in non-critical applications present ongoing solutions to reduce downstream impact. Disposal as hazardous chemical waste reduces the risk of environmental introduction, protecting waterways and aquatic life.
Triclosan’s standing as a raw material in pharmaceuticals focuses on its ability to fight bacteria at low concentrations. Its inclusion in hand soaps, wound care, and medical devices reflects decades of clinical evidence showing efficacy against Staphylococcus, Escherichia coli, and various Gram-positive and Gram-negative strains. Scientific reviews highlight how long-standing use in personal care aligns with the rapid, surface-level antimicrobial action needed for public and medical hygiene. Yet, the push for responsible usage steers companies to rethink unnecessary, non-medical deployment, aiming to balance infection control and the broader challenge of antimicrobial resistance. Alternatives do exist—alcohols, chlorhexidine, newer non-halogenated antimicrobials—so regulatory and risk-based reviews decide where Triclosan remains justified as a raw material.
Authorities across regions routinely review the health and ecological records on Triclosan. The US Environmental Protection Agency (EPA) lists it as a regulated industrial chemical, and pharmaceutical-grade material requires accompanying certification documents attesting to specification compliance. The European Union’s REACH regulation monitors its use in industrial and commercial settings. Studies charting residue in waterways led several countries to limit or outright ban Triclosan in soaps and cosmetics meant for general consumer use. This regulatory patchwork demands that buyers keep close tabs on evolving compliance requirements and invest in sustainable formulation choices. Industry-wide solutions include material substitution, more robust wastewater treatment, and lifecycle analysis to predict cumulative exposure in natural ecosystems.
Years spent around chemical manufacturing and regulatory audits highlight the need for vigilance in handling compounds like Triclosan. It figures on restricted lists in many consumer goods companies due to persistent environmental footprint and the specter of contributing to antimicrobial resistance. Yet, pharma-grade material—rigidly purified and meticulously controlled—still holds a key place in clinics where hygiene outweighs raw environmental calculus. Open communication between shippers, buyers, and regulators leads to the safest possible use. Suppliers who invest in robust traceability and open, science-based information-sharing help buyers navigate the landscape and uphold product safety.
Triclosan BP EP USP Pharma Grade marks itself with high purity, distinctive white crystalline appearance, and stable core structure. Its molecular formula—C12H7Cl3O2—sets it apart as a potent antimicrobial. Physical state varies—powder, flakes, pearls—for optimal adaptability in manufacturing. Safety routines center on limiting inhalation, minimizing skin contact, and enforcing proper waste treatment. Though concerns mount regarding environmental persistence, careful sourcing, handling, and transparent regulatory conformity support ethical application in healthcare and select industrial use. By anchoring formulation work in robust science and regulatory due diligence, the supply chain ensures that Triclosan’s benefits meet safety obligations at every step.
