Abstract: The present invention is directed to a depilatory composition which comprises a depilatory active and at least one material which alters the thermal properties of the composition by either having a higher heat of fusion or a lower thermal conductivity than the bulk.

Abstract: An air cleaner is described comprising a housing having an air inlet and an air exhaust extending therethrough, a refill for containing a reservoir of liquid which is releasable from the housing, a nebuliser within the housing configured, in use, to be in fluid contact with the source of liquid to generate a mist of liquid droplets, said nebuliser being configured, in use, to eject the mist upwardly, a chamber within the housing in which the mist is retained, a fan within the housing configured, in use, to generate a flow of air through the air inlet and into the chamber such that at least some of the contaminants in the air flow are urged by the mist out of the flow of air and toward the refill. A refill for the air cleaner is also described as well as the use of said air cleaner.
