The invention relates to bar compositions comprising thermochromatic pigment or dye signaling temperature and/or benefit agent release. In a preferred embodiment, the pigment is introduced in the form of a separate domain (e.g., separate chips) which separate chip or chips is combined with surfactant-containing chips to form the final bar. The invention further relates to a method of signaling temperature and/or benefit agent release using these bars.

Cette invention a trait à des compositions en barres comprenant un pigment ou un colorant thermochromique indicateur de température et/ou de libération d'un agent à effet bénéfique. Dans un mode de réalisation préféré, le pigment est introduit sous forme de domaine séparé (par exemple sous forme de cristaux distincts), lesdits cristaux distincts étant combinés avec des cristaux contenant un tensioactif de manière à former la barre finale.
