    Abstract: The present invention relates to a liquid bleaching composition comprising a bleach and a substantially linear nonionic surfactant, whereby said substantially linear nonionic surfactant has the general formula: R—(A)x—(B)y—(C)z—O—R1 wherein: R is an even numbered C6 to C22 alkyl chain or a mixture thereof, containing at least 90% linear alkyl chains; A is an ethoxy unit; B is a butoxy unit; C is a propoxy unit; x, y and z are independent integers of from 0 to 20; the sum of x+y+z is at least 2, wherein when x is equal to or greater than 1. y+z is equal to or greater than 1; and R1 is H, a C6 to C22 alkyl chain or a C6 to C28 alkyl benzene chain. Furthermore, the present invention relates to the use of said substantially linear nonionic surfactant in a fabric bleaching composition comprising a bleach to treat a fabric whereby stain removal and/or bleaching benefits are provided.
