Bad odors on textile materials are often caused by body odor. The invention relates to a textile material treatment method for inhibiting body odor on textile materials, by which means the treated textiles, after having been worn, even after sweat-inducing sports activities, have a significantly reduced bad odor or even no odor. The invention also relates to a perfume composition and to a textile material treatment agent, respectively comprising urea derivatives and/or phenacylthiazolium salts, that counteract the formation of body odor.
