The present invention provides a softener composition, which attaches onto the fabric during the rinsing process, and thus enables the fabric to have the anti-ultraviolet function. The softener composition comprises (A) 0.05 to 50 wt % of polyurethane-based polymeric UV light absorber, (B) 2 to 15 wt % of cationic softener, and (C) 35 to 97 wt % of water.
