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.

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.

Product Description

Triclocarban (TCC) CAS 101-20-2 is 3,4,4′-trichlorocarbanilide, with the formula C₁₃H₉Cl₃N₂O and EINECS 202-924-1.

Synonyms: TCC; 3,4,4′-Trichlorocarbanilide; Triclocarbanum; N-(4-chlorophenyl)-N′-(3,4-dichlorophenyl)urea; Cutisan.

CAS: 101-20-2.

Molecular formula: C₁₃H₉Cl₃N₂O.

It is supplied as a fine white powder.

TCC is a lipophilic carbanilide derivative that disrupts microbial cell membrane integrity.

Its activity is especially associated with gram-positive bacteria and some fungi.

Its low water solubility and persistent nature make it suited to long-lasting bacteriostatic treatment.

It is used in antibacterial soaps and detergents, disinfectant and biocide formulations, textile finishing and specialty coatings.

The typical assay (HPLC) is about 98.0% or higher, with a melting point of about 250-255 °C.

It has very low water solubility, below about 0.1 g/100 mL at 26 °C, but is soluble in methanol or hot isopropanol.

It is usually predispersed in a compatible organic phase or solid matrix rather than dissolved directly in water.

Store in a cool, dry, well-ventilated area away from strong oxidizing agents, with the container tightly closed.

Protect from moisture and contamination, and keep containers closed when not in use.

Confirm appearance, assay, melting point, loss on drying, chloroaniline content, particle size and grade as required.

Use suitable eye and skin protection during handling, and wash skin contact with soap and water.

Confirm packaging with the requested quantity and destination requirements.

FAQ - Technical & Supply Chain

Q:
What is Triclocarban Powder CAS 101-20-2?

A: 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.
Q:
How does Triclocarban TCC provide antimicrobial performance?

A: 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.
