摘要:
A phosphate-free dishwasher detergent which contains a builder, bleaching agents, and also a) a copolymer comprising i) monomers from the group of mono- or polyunsaturated carboxylic acids; ii) monomers of general formula R1(R2)C═C(R3)—X—R4; and iii) optionally further monomers, and b) a nonionic surfactant of general formula R1—CH(OH)CH2O-(AO)w-(A′O)x-(A″O)y-(A′″O)z—R2. The detergent has good cleaning and rinsing results which are comparable to those of phosphate-containing dishwasher detergents or even outdo them.
摘要:
An automatic dishwashing or automatic textile washing method includes the step of dispensing a cleaning-agent presentation form into the interior of an automatic dishwasher or textile washing machine from a cartridge located in the interior of the automatic dishwasher or textile washing machine. The cleaning-agent presentation form includes a liquid cleaning-agent preparation A having a pH (10% solution in H2O; 20° C.) above 8.0, comprising at least one builder as well as at least one oxygen bleaching agent, and a liquid cleaning-agent preparation B comprising at least one bleach activator. Sub-quantities a and b of the cleaning-agent preparations A and B are respectively dispensed so that a residual quantity of the cleaning-agent preparations A and B remain in the cartridge until the end of the dishwashing method or textile washing method, and the residual quantities corresponds to at least twice the quantity of sub-quantities a and b.
摘要:
The present invention is a phosphate-free automatic dishwashing agent containing a builder, said agent comprising: a) a copolymer A comprising i) at least one mono- or polyunsaturated carboxylic acid monomer, ii) at least one mono- or polyunsaturated sulfonic acid monomer, and iii) at least one additional nonionic monomer; and b) an acrylic acid homopolymer B, wherein the weight ratio of copolymer A to homopolymer B is between 10:1 and 1:3. The present agent is characterized by excellent residue inhibition, good cleaning, and clear rinsing performance in automatic dishwashing.
摘要:
A method for operating an automatic dishwasher is disclosed. Provided are a dispenser, a cartridge with a chamber of rinse aid, a washing program including a cleaning program, and a sensor for measuring soil on the dishware or in the wash. The soiling is compared to a reference value and if less than reference, the temperature of the wash is held to ≦65° C., and at the end of the cleaning program and/or the intermediate rinse cycle, rinse aid is dispensed and drying immediately follows the cleaning program and/or intermediate rinse cycle without execution of a rinse aid program.
摘要:
Phosphate-free, bleach-free automatic dishwashing agents comprising 10 to 60 wt % citrate and from 1 to 30 wt % maleic acid are described, wherein the automatic dishwashing agents are characterized by good cleaning performance, particularly in the improved cleaning of tea stains.
摘要:
A method of machine cleaning dishes in a dishwasher, wherein over the course of a cleaning program, having a pre-rinsing operation and a cleaning operation, two liquid cleansers A and B having the following composition: A:—10 to 75 wt % of builder(s); −0.1 to 10 wt % of enzyme(s); −24.9 to 89.9 wt % of solvent; and B: −10 to 74.9 wt % of builder(s); −25 to 89.9 wt % of solvent; are metered into the wash bath at two successive times t1 and t2. The liquid cleanser A has a pH value (20° C.) of between 6 and 9 and is metered in at time t1, while the liquid cleanser B has a pH value (20° C.) of between 9 and 14 and is metered in at time t2.
摘要:
The invention relates to low-alkaline and bleach-free dishwasher detergents having a pH value (20° C.) between 8 and 12, comprising a) 10 to 60 wt % of citrate, b) 1.5 to 30 wt % anionic copolymer, comprising i) unsaturated monocarboxylic acid(s) A ii) unsaturated dicarboxylic acid(s) B, characterized by good cleaning action, particularly improved cleaning of tea.
