摘要： A process for freshening cloth which comprises the sequential steps of: a) contacting the cloth with human skin to treat the cloth with sebum, b) washing the cloth in a surfactant solution (preferably at a temperature of below 30 Celsius) comprising a singlet oxygen photo-bleach (preferably a water-soluble phthalocyanine compound or a water soluble xanthene) to imperfectly remove the sebum and deposit photo-bleach on the cloth, c) exposing the cloth to light, preferably direct sunlight, whereby the deposited photo-bleach reacts with the residual sebum to produce an odiferous species, wherein a further catalytic agent which is not a photo-catalyst but which catalyses the conversion of hydroperoxides into odiferous species is present during at least step (b). Preferably, a blue or violet shading dye is present at least in step (b). Advantageously a further catalyst is present in step (c) to assist in the formation of odiferous species from intermediate hydroperoxides.
