Abstract
Official abstract text for this publication.
The application describes the use of porous polyamide particles which have a volume-weighted median particle size of 1 to 50 μm, an oil absorption capacity of at least 60 g/100 g, and a specific BET surface area (as specified in DIN 66131) of 1 to 20 m 2 /g, for removing greasy stains from textile surfaces in a laundry detergent or cleaning agent which is used in a laundry or cleaning process.
First claim
Opening claim text (preview).
What is claimed is: 1. A laundry detergent comprising 0.5 to 10 wt % porous polyamide particles having a volume-weighted median particle size of 1 to 50 μm, an oil absorption capacity of at least 60 g/100 g, and a specific BET surface (as specified in DIN 66131) of 1 to 20 m 2 /g; wherein the laundry detergent further comprises: from 8 to 30 wt % surfactants selected from the group consisting of anionic surfactants, non-ionic surfactants, and mixtures thereof; from 1 to 8 wt % organic builder; from 0.2 to 4 wt % enzyme(s) selected from the classes of enzymes consisting of amylases, proteases, lipases, cutinases, pullulanases, hemicellulases, and mixtures thereof; and from 2 to 20 wt % organic solvent(s) selected from alcohols having from 1 to 4 C atoms, ethers derivable therefrom, and mixtures thereof. 2. The laundry detergent according to claim 1 , wherein the polyamide particles contain polyamide-6, polyamide-12, copolyamide-6/12 or mixtures thereof. 3. The laundry detergent according to claim 1 , wherein the polyamide particles have a volume-weighted median particle size of 2 to 40 μm. 4. The laundry detergent according to claim 1 , wherein the polyamide particles have an oil absorption capacity of 80 g/100 g to 250 g/100 g. 5. The laundry detergent according to claim 1 , wherein the polyamide particles have a specific BET surface (as specified in DIN 66131) of 1 to 15 m 2 /g.
