The use is described of compositions comprising (a) (&#x2212;)-guaiol, (b) further skin-lightening active substance(s) and, optionally, (c) one or more UV-A and/or UV-B absorbers as melanogenesis inhibitors and for skin-lightening.

Use of guaiol for treating the skin

The present invention relates to the use of hydroxydiphenyl ether compounds as antimicrobially active substances, to certain new compounds of this type and to processes for the preparation of these compounds.

Antimicrobial method using a hydroxydiphenyl ether compound

A process for the antimicrobial treatment of fiber materials, comprising applying to the fiber material an inclusion complex of a fiber-reactive cyclodextrin derivative with an antimicrobial agent selected from the group consisting of (a) halogeno-o-hydroxydiphenyl compounds or non-halogenated hydroxydiphenyl ether compounds; (b) phenol derivatives; (c) benzyl alcohols; (d) chlorohexidine and derivatives thereof; (e) Calkybetaines and C&#x2013;Cfatty acid amidoaklylbetaines; (f) amphoteric surfactants; (g) trihalocarbanilides; (h) quaternary and polyquaternary compounds; and (i) thiazole compounds.

Process for the antimicrobial treatment of fiber materials

A surface-active composition is described which comprises The compositions are used for the antimicrobial treatment of human skin and hair, of hard surfaces and of textile fibre materials.
