A stable soil release promoting enzymatic primarily nonionic liquid detergent composition comprises a synthetic organic nonionic detergent, an anionic sulf(on)ated synthetic organic detergent, a particular type of soil release promoting copolymer of polyethylene terephthalate (PET) and polyoxyethylene terephthalate (POET), a proportion of enzyme(s) sufficient to enzymatically hydrolyze proteinaceous and/or amylaceous soils on fabrics during washing thereof with an aqueous washing solution of the liquid detergent, a fluorescent brightener, a stabilizing proportion of a stabilizer for the enzyme(s), which also acts as a buffer for the liquid detergent composition to maintain the pH in a certain neutral or slightly acidic range to stabilize the PET - POET copolymer and the fluorescent brightener, and an aqueous medium. The described composition is non-separating and is chemically stable on storage. It substantially retains its soil hydrolyzing, fluorescent brightening and soil release promoting characteristics on storage, so that laundry washed with it is effectively cleaned, brightened, and treated. Also within the invention are processes for manufacturing the product and for utilizing it to wash laundry.

Stable soil release promoting enzymatic liquid detergent composition

A stable fabric softening, soil release promoting, enzyme-containing nonionic liquid detergent, preferably transparent or translucent, comprises a detersive proportion of a synthetic organic nonionic detergent, a soil release promoting proportion of a particular type of soil release promoting copolymer of polyethylene terephthalate and polyoxyethylene terephthalate, a softening proportion of a quaternary ammonium halide fabric softener, a proportion of enzyme sufficient to enzymatically hydrolyze proteinaceous and/or amylaceous soils on fabrics during washing thereof with an aqueous washing solution of the liquid detergent, a stabilizing proportion of a stabilizer for the enzyme(s), and an aqueous medium. The pH is in a certain range and the proportion of ionizable material present is limited. The described liquid detergent can be clear in appearance and is non-separating and of improved stability on storage (especially important with respect to enzymatic stability and effectiveness), with substantial retention of soil release promoting and hydrolyzing characteristics, so that laundry containing polyester materials is effectively cleaned and readily releases soil from it upon washing with the liquid detergent.

Stable soil release promoting liquid detergent containing fabric

The gelling temperature of liquid nonionic detergents is lowered by 2.degree. C. or more by the addition of aliphatic linear or aliphatic monocyclic dicarboxylic acids such as the C.sub.6 to C.sub.12 alkyl and alkenyl derivatives of succinic acid or maleic acid and the corresponding anhydrides. Non-aqueous heavy duty built liquid laundry detergent compositions which do not gel when added to water at a temperature near freezing are disclosed.

Non-gelling non-aqueous liquid detergent composition containing higher

A soil release promoting, enzyme-containing nonionic detergent based liquid detergent, of high active ingredients concentrations and preferably transparent or translucent, comprises a synthetic organic nonionic detergent, a higher fatty alcohol polyethoxylate sulfate, a particular type of soil release promoting copolymer of polyethylene terephthalate and polyoxyethylene terephthalate, a proportion of enzyme(s) sufficient to enzymatically hydrolyze proteinaceous and/or amylaceous soils on fabrics during washing thereof with an aqueous washing solution of the liquid detergent, a stabilizing proportion of a stabilizer for the enzyme(s), and an aqueous medium. The pH is in a certain range and the proportion of ionizable material present is limited. The described liquid detergent can be clear in appearance and is non-separating and of improved stability on storage, with substantial retention of soil release promoting and soil hydrolyzing characteristics, so that laundry containing polyester materials is effectively cleaned and soils are readily released from it when it is washed with the liquid detergent.

Stable soil release promoting liquid detergent containing stabilized
