Abstract
The disclosure relates to compositions particularly suited for removing soils from textiles, in particular the removal of oily food soils, oily cosmetic soils, and industrial soils from textiles containing cotton, particularly those comprising one or more of surfactants, and cationic amines, or silicone compounds. Methods of making and using such compounds are also provided.
Claims16
A method of removing soil from a textile comprising:
- washing a textile during a wash cycle, wherein the wash cycle comprises a pre-soak phase, a wash phase, a rinsing phase, a finishing phase, and an extraction phase;
- applying a finishing composition to a surface of the textile during the finishing phase;
- the finishing composition comprising:
- a branched cationic amine surfactant comprising N, N-bis(3-aminopropyl) dodecylamine;
- N1,N1,N3-tris (3-aminopropyl)-N3-dodecylpropane-1,3-diamine;
- N1,N1-bis(3-aminopropyl)-N3-dodecylpropane-1,3-diamine;
- N1-(3-aminopropyl)-N3-dodecylpropane-1,3-diamine;
- N-dodecylpropane-1,3-diamine;
- isotridecyloxypropyl-1,3-diaminopropane;
- N1-(3-(tridecyl-(branched)-alkyloxy) propyl) propane-1,3-diamine;
- N1,N1,N3-tris (3-aminopropyl)-N3-octadecyl-1,3-propanediamine;
- N1,N1,N3-tris (3-aminopropyl)-N3-dodecylpropane-1,3-diamine;
- N-(3-aminopropyl)-N-octadecyl-N-octadecyl propane-1,3-diamine;
- or a combination thereof;
- one or more additional surfactants, wherein the one or more additional surfactants comprises a nonionic surfactant, semi-polar nonionic surfactant, a cationic surfactant, or a combination thereof;
- and
- a deposition aid comprising a quaternary ammonium compound, a silicone compound, an amine epoxide adduct, or a combination thereof;
- and
- wherein the finishing composition is applied in a concentration to deposit 10-200 ppm of the branched cationic amine surfactant to the surface of the textile, the deposited branched cationic amine surfactant remains on the surface of the textile after drying, and the deposited branched cationic amine provides improved removal of soil in a subsequent wash;
- and
- wherein the soil is removed from the textile.
