A fabric softener composition for liquid carbon dioxide-based cleaning includes: an organic solvent expressed as chemical formula 1, and a cationic surfactant, where the chemical formula 1 is R1-O(CO)OR2, and R1 and R2 are hydrogen (H) or an alkyl group having 1 to 4 carbon atoms.

An aqueous liquid laundry formulation is provided, comprising: a liquid carrier; a cellulase; and a protectant polymer, wherein the protectant polymer comprises: 25 to 65 wt %, based on weight of the protectant polymer, of structural units of formula I ##STR00001##
wherein each R.sup.1 is independently selected from a hydrogen and a CH.sub.3 group; and 35 to 75 wt %, based on weight of the protectant polymer, of structural units of formula II ##STR00002##
wherein each R.sup.2 is independently selected from a C.sub.2-3 alkyl group and wherein each R.sup.3 is independently selected from a hydrogen and a methyl group. Also provided is a method of renewing a soiled cotton containing fabric using aqueous liquid laundry formulation.
