Description
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.
Cosmetic preservatives are incorporated to preserve the microbiological integrity of the product throughout its shelf life. The information presented is for technical reference only and does not constitute a recommendation for use or an efficacy claim.
