What is Triclocarban?

Triclocarban is a synthetic compound, chemically 3,4,4'-trichlorocarbanilide, belonging to the carbanilide family of antimicrobials. Developed for personal care applications, it appears mainly in rinse-off products like bar soaps, body washes, and deodorant bars. In cosmetics, it operates by interfering with bacterial fatty acid synthesis through inhibition of the enoyl reductase enzyme, effectively reducing populations of gram-positive bacteria responsible for odor and spoilage. This dual role supports product stability during use and storage while contributing to freshness on skin surfaces. Its water-insoluble nature allows incorporation into solid formulations where it releases gradually upon contact with moisture, targeting microbes without broadly affecting skin flora.

Deodorant agent
Targets malodor by neutralizing odor molecules, inhibiting odor-causing microbes, or adding fragrance notes to improve underarm and body freshness.
Preservative
Protects the product from microbial contamination during storage and use, helping maintain safety, stability, and shelf life.
Deodorant
Helps control body odor by reducing odor-causing bacteria and/or neutralizing or masking malodor, without necessarily reducing sweat production.
