  Antiperspirant compositions containing a pigment often exhibit a dull colour if an inorganic pigment is employed, but if many bright organic pigments are used, the pigment is subject to photodegradation and accordingly fades. By incorporating selected types of polycyclic organic pigment, namely an organic pigment containing condensed aromatic or heterocyclic ring system that is free from an azo substituent and does not comprise, a di or th-arylcarbonium, or a xanthene based pigment, the antiperspirant composition comprises a bright pigment that is resistant to photodegradation. The composition is preferably anhydrous and advantageously a firm stick.
