Abstract
Super-concentrated liquid rinse cycle fabric softeners are provided which contain more than 35%, by weight, of a fabric softening system based on an amidoamine fabric softener, such as bis(tallow amidoethyl)-2-hydroxyethyl amine and a quaternary diester fabric softener, such as N-methyl, N,N,N-triethanolamine ditallow ester quaternary ammonium salt. A fatty alcohol ethoxylate surfactant and a polyethylene glycol polymer or a polyethylene glycol alkyl ether polymer are integral components of the liquid composition. The super-concentrated compositions may be used at low levels or may be further diluted prior to use.
