The present invention relates to a composition comprising a photo-bleaching component and a fluorescent whitening component having good compatibility. In particular, the present invention relates to a composition suitable for the treatment of textiles, comprising a photo-bleaching component and a fluorescent whitening component, wherein the photo-bleaching component is capable of absorbing light to form an intermediate energetically excited photo-bleaching component, the intermediate energetically excited photo-bleaching component is capable of activating molecular oxygen from its triplet oxygen electronic energy state to its singlet oxygen electronic energy state, characterised in that the intermediate energetically excited photo-bleaching component has a lifetime of greater than 50 microseconds, preferably greater than 100 microseconds, more preferably greater than 200 microseconds, and most preferably greater than 300 microseconds.
