Abstract:
The present invention provides a paste-like cleaning or detergent composition comprising a) a surfactant component comprising a compound of the general formula R 1 -COOM (1), a fatty alcohol alkoxylate and/or an oxo alcohol alkoxylate with an average degree of alkoxylation at least 5; and optionally an anionic surfactant; b) a compound of the general formula R 2 -O-R 3 (II); c) water and/or a compound of the general formula X-CH 2 -(CHY) n -CH 2 -Z (III), provided that at least 2 hydroxyl groups are present; d) an alkalinity source, and e) one or more organic and/or anorganic builders on a non-silicate basis; wherein the composition essentially is free from graying inhibitors on a cellulose basis, silicates and phosphates. Moreover, the present invention relates to a method for washing textiles using said composition, wherein the waste water accumulated during the washing process may be purified by a membrane filtration unit comprising reverse osmosis steps.
Abstract:
The invention relates to liquid detergent concentrate composition comprising an emulsion having a water phase and an oil phase, the composition comprising 5 - 30 wt-% of one or more alkalinity source 1 - 70 wt-% of a at least one non-ionic surfactant 0.01 - 10 wt-% of one or more crosslinked or partly crosslinked polyacrylic acid or polymethacrylic acid. Furthermore the invention relates to a stable aqueous use solution, comprising a liquid detergent concentrate according to the invention and to a method for washing textiles with the aqueous use solution.
Abstract:
The invention relates to a paste-like cleaning or detergent composition comprising a) a surfactant component comprising a compound of the general formula R 1 -COOM (I), wherein R 1 represents a linear or branched alkyl- or alkenyl residue with 8 to 22 carbon atoms and M represents an alkali metal ion; a fatty alcohol alkoxylate and/or an oxo alcohol alkoxylate with 8 to 22 carbon atoms and an average degree of alkoxylation of at least 5; and optionally an anionic surfactant; b) a compound of the general formula R2-O-R3 (II), wherein R2 represents a linear or branched alkyl or alkenyl residue with 8 to 22 carbon atoms and R3 represents hydrogen or a linear or branched alkyl residue with 1 to 8 carbon atoms; c) water and/or a compound of the general formula X-CH2-(CHY)n-CH2-Z (Hi), d) wherein n is an integer of from 0 to 2 and X, Y and Z independently symbolize hydrogen or a hydroxyl group provided that at least 2 hydroxyl groups are present; e) one or more alkalinity sources f) one or more organic and/or anorganic builders on a non-silicate basis; g) a defoamer comprising crosslinked or partly crosslinked polysiloxane having a three dimensional structure.
Abstract:
The present invention refers to a method of activating membranes useful in separation processes, wherein the membrane is contacted for at least one day with a liquid activating agent comprising at least one acid and at least one surfactant. A further object is the provision of activated membranes as well as the use thereof in a separation process.
Abstract:
The invent ion related to a membrane-compatible cleaning or detergent composition free from any phosphates, silicates and cellulose-based compounds, comprising 5 to 30 wt% of a phosphate substitute as well as a method for washing textiles using this composition. Said cleaning or detergent composition comprises a water-soluble copolymer and a multidentate chelating agent.
