What is Triclocarban Powder CAS 101-20-2?

Triclocarban, commonly abbreviated TCC, is 3,4,4'-trichlorocarbanilide with the molecular formula C13H9Cl3N2O and molecular weight about 315.58 g/mol. It is supplied as a fine white powder and is used mainly as a persistent bacteriostatic active in industrial and technical antimicrobial formulations.

How does Triclocarban TCC provide antimicrobial performance?

TCC is a lipophilic carbanilide derivative that disrupts microbial cell membrane integrity, with activity especially associated with gram-positive bacteria and some fungi. Its low water solubility and persistent nature make it suited to long-lasting bacteriostatic treatment rather than a quick-rinse water-soluble active.

Which industrial applications commonly use Triclocarban CAS 101-20-2?

It is used in antibacterial soaps and detergents, disinfectant/biocide formulations, textile finishing, specialty coatings, and other non-aqueous or solid antimicrobial matrices. The technical grade is generally selected for industrial processing where particle size, purity, and compatibility are controlled.

Why does Triclocarban require a non-aqueous or dispersed incorporation method?

Triclocarban has very low water solubility, below about 0.1 g/100 mL at 26 degrees C, while being soluble in solvents such as methanol or hot isopropanol. Formulators therefore predisperse it in a compatible organic phase or solid matrix rather than trying to dissolve it directly in water.

Triclocarban Powder CAS 101-20-2

Triclocarban CAS 101-20-2 is a highly effective carbanilide derivative functioning as a persistent bacteriostatic agent within the Biocides & Preservatives sector. As a fine white powder, this 3,4,4'-Trichlorocarbanilide works through the disruption of microbial cell membrane integrity, specifically targeting gram-positive bacteria in diverse industrial applications. This TCC compound is characterized by its high lipophilicity and low water solubility, making it a preferred Triclocarbanum choice for integration into solid and non-aqueous surfactant matrices. Beyond its primary role, N-(4-chlorophenyl)-N'-(3,4-dichlorophenyl)urea serves as a stable chemical intermediate in specialized industrial coatings and textile treatments where long-term antimicrobial protection is required. Our production lines ensure competitive factory pricing for bulk procurement, offering customized specifications regarding particle size and purity levels. Detailed technical documentation, including MSDS, TDS, COA, is provided with every shipment to ensure full compliance for bulk supply operations.

Applications

Industrial Surfactants: Integrated into specialized industrial cleansing bars and detergents where persistent bacteriostatic activity is required on surfaces.
Textile Auxiliaries: Applied in the treatment of technical textiles to prevent microbial degradation and odor formation in industrial fabrics.
Polymer Additives: Used as a preservative in plastics and rubber materials to inhibit the growth of bacteria and fungi during the product’s service life.

For applications where a different chlorinated antimicrobial active is specified, Triclosan is a separate material and applicable restrictions should be reviewed.

Storage & Safety

Storage: Store in a cool, dry, and well-ventilated area away from strong oxidizing agents. Keep the container tightly closed to prevent moisture absorption and contamination.
Safety (PPE): Use a dust mask or respirator (N95 or equivalent), safety goggles, and chemical-resistant gloves. Avoid direct skin contact and dust inhalation. Ensure the work area is equipped with an eyewash station.

Quality Assurance

Our quality control laboratory employs high-resolution High-Performance Liquid Chromatography (HPLC) to monitor both active content and trace impurities, such as residual chloroanilines. By maintaining strict adherence to industrial manufacturing standards, we ensure that the physical properties—specifically particle size distribution—remain consistent for optimal dispersion in various industrial formulation bases.
