TRICLOCARBAN

Triclocarban is a substituted carbanilide, that is, a diphenyl-substituted urea derivative that incorporates chlorine atoms at the aromatic positions. Chemically it belongs to the family of halogenated diarylureas, organic compounds characterized by a central urea group bound to two chlorinated benzene rings. Its declared technical function in cosmetics is antimicrobial, deodorant and preservative. Ingredients of this type are incorporated into cosmetic formulations to help control microbial growth in the product or on the application surface, as well as to modulate body odor. It is also identified under the names 1-(4-chlorophenyl)-3-(3,4-dichlorophenyl)urea and triclocarban as the international nonproprietary name.

Under Regulation (EC) No 1223/2009 on cosmetic products, this ingredient is listed in Annex III (list of substances which cosmetic products must not contain except subject to the restrictions laid down), under reference 100. The maximum authorized concentration in the finished cosmetic product is "1.5%". The authorized product type is limited to "Rinse-off products", that is, products intended to be removed by rinsing after application. The purity criteria laid down require control of "3, 3', 4, 4'-Tetrachloroazobenzene". In addition, the substance is referenced in Annex V under reference 23, which corresponds to the list of authorized preservatives. No additional mandatory labelling warnings are laid down beyond the restrictions cited, and no associated CMR classification is recorded.

In cosmetic formulation in general, ingredients with a preservative function help preserve the microbiological integrity of the product throughout its shelf life. Its use is conditional on strict compliance with the restrictions of the applicable annex, including the cross-references III/100 and V/23. The information presented is for technical reference only and does not constitute a recommendation for use or an efficacy claim.

Triclocarban is a substituted carbanilide, that is, a urea derivative with chlorinated aromatic rings in its structure. In chemical nomenclature it corresponds to the family of halogenated diarylureas. Within the cosmetic framework, its declared technical function is antimicrobial, deodorant and preservative. Ingredients with an antimicrobial and preservative function act, in general terms, by controlling the proliferation of microorganisms in a formulation, while deodorants help modulate the microbial load associated with body odor. Among its identifiers are the alternative names 1-(4-chlorophenyl)-3-(3,4-dichlorophenyl)urea and triclocarban.

Under Regulation (EC) No 1223/2009, the ingredient is included in Annex V, reference 23, which corresponds to the list of authorized preservatives. The maximum permitted concentration in the finished cosmetic product is "0,2 %", applicable to "all cosmetic products, with the exception of mouthwash". The annex lays down purity criteria requiring that the contaminants 3,3',4,4'-tetrachloroazobenzene and 3,3',4,4'-tetrachloroazoxybenzene be kept at levels "≤ 1 ppm". In addition, the regulatory text provides that the substance must not be used in toothpastes intended for children under 6 years of age. For toothpastes containing Triclocarban, the mandatory labelling must include the literal warning: "Not to be used for children under 6 years of age". The substance is not classified as CMR. It also appears with cross-restrictions in Annex III, reference 100.
