BAR COMPOSITION COMPRISING THERMOCHROMIC PIGMENT OR DYE SIGNALING BENEFIT AGENT RELEASE OR OTHER USE AND METHOD OF SIGNALING THEREOF

摘要

The invention relates to bar compositions comprising thermochromatic pigm ent or dye signaling temperature and/or benefit agent release. In a preferre d 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 bar s.
