摘要:
Phosphate-free dishwasher detergents which contain a builder, bleaching agents, a nonionic surfactant, and also a) a copolymer comprising i) sulfonic acid group-containing monomers, ii) further ionic and/or nonionic monomer, and b) phosphonate. The detergents have good scale-inhibiting, cleaning and rinsing results which are comparable to those of phosphate-containing dishwasher detergents or even outdo them.

摘要:
The invention relates to a combination product comprising a packaging means and two liquid washing or cleaning agents A and B of composition A, which are located in said packaging means while being separated from one another therein. Composition A consists of: 10 to 75% by weight of builder(s); 0.1 to 10% by weight of enzyme(s); 24.9 to 89.9% by weight of water, and composition B consists of: 10 to 74.9% by weight of builder(s); 25 to 89.9% by weight of water, and; 0.1 to 15% by weight of bleaching agent. The invention is characterized in that the liquid cleaning agent A has a pH value (20° C.) ranging from 6 to 9 and is characterized by having an improved cleaning efficiency compared to that of conventional solid or liquid dishwashing cleaning agents.

The invention relates to a solid dishwasher detergent which comprises a) 1 to 40 wt. % of a bleaching agent, b) 0.25 to 20 wt. % of non-ionic surfactants(s); and c) 0.01 to 10 wt. % of at least one polymer having a molar mass of 2000 gmol−1 or more and having at least one positive charge. The detergent is characterized in that the weight ratio of component b) to component c) ranges between 25:1 and 100:1, preferably between 30:1 and 80:1, and specifically between 35:1 and 75:1. The inventive dishwasher detergent is characterized by an improved cleaning and rinsing power and improved processability and shelf life.

Combination products comprising packaging and two liquid cleansers or detergents A and which are separated from each other in the packaging and wherein the cleansers or detergents A and B comprise: A: 10% to 75% by weight of detergent builder(s), 0.1 % to 10% by weight of enzyme(s), 24.9% to 89.9% by weight of water; and B: 10% to 75% by weight of detergent builder(s), 25% to 90% by weight of water; characterized in that the cleanser or detergent A has a pH value (at 20° C.) between 6 and 9 and the cleanser or detergent B has a pH value (at 20° C.) between 9 and 14, and neither cleanser or detergent A nor cleanser or detergent B comprises more than 2% by weight of a bleaching agent. The combination products of the invention demonstrate improved cleaning performance over conventional products, particularly regarding bleachable stains and when used as dishwashing detergents.

Phosphate-free dishwasher detergents which contain a builder, bleaching agents, a nonionic surfactant, and also a) a copolymer comprising i) sulfonic acid group-containing monomers, ii) further ionic and/or nonionic monomers, b) methyl glycine diacetic acid. The detergents according to the invention have good cleaning and rinsing results which are comparable to those of phosphate-containing dishwasher detergents or even outdo them.
摘要:
An automatic dishwashing agent includes builder(s), enzyme(s) and a) a nonionic surfactant A of the general formula R1O(AlkO)xM(OAlk)yOR2, in which R1 and R2 mutually independently denote a branched or unbranched, saturated or unsaturated, optionally hydroxylated alkyl residue with 4 to 22 carbon atoms; Alk denotes a branched or unbranched alkyl residue with 2 to 4 carbon atoms; x and y mutually independently denote values between 1 and 70; and M denotes an alkyl residue from the group CH2, CHR3, CR3R4, CH2CHR3 and CHR3CHR4, with R3 and R4 mutually independently denoting a branched or unbranched, saturated or unsaturated alkyl residue with 1 to 18 carbon atoms; b) a nonionic surfactant B which differs from the nonionic surfactant A; and c) an anionic copolymer C. The agent imparts an improved drying and rinsing result.

The invention relates to a phosphate- and bleach-free automatic dishwashing agent containing: a) 5 to 60 wt % citrate, b) (hydrogen) carbonate, c) 2 to 40 wt % ethylenediamine disuccinic acid, wherein the weight ratio of the components b) and c) is between 1:5 and 10:1, and wherein said automatic dishwashing agent is characterized by good cleaning performance, particularly improved cleaning of tea.
摘要:
Liquid, aqueous washing or cleaning product formulation, comprising a) at least one washing- or cleaning-active enzyme; b) 1,2-propylene glycol; and c) nonionic surfactant of the general formula R1—CH(OH)CH2O-(AO)w-(A′O)x-(A′O)y-(A″O)z—R2, wherein R1 is a straight-chain or branched, saturated or mono- or polyunsaturated C6-24-alkyl or -alkenyl radical; R2 is a linear or branched hydrocarbon radical having from 2 to 26 carbon atoms; A, A′, A′ and A″ are each independently a radical from the group of —CH2CH2, —CH2CH2—CH2, —CH2—CH(CH3), —CH2—CH2—CH2—CH2, —CH2—CH(CH3)—CH2—, and —CH2—CH(CH2—CH3); and w, x, y and z are each values from 0.5 to 120, where x, y and/or z may also be 0, are notable for good phase and enzyme stability and good cleaning performance.
摘要:
Process for cleaning dishes in a dishwasher during which the aqueous washing liquor contained in the interior of the dishwasher is at least partly removed from the interior of the dishwasher at a point in time t. The process involves metering a dishwasher detergent A containing one or more surfactants and one or more anionic polymers at a time t1 t in an amount m2 into the interior of the dishwasher. The process according to the invention differs from conventional cleaning processes in that formation of deposits is reduced and drying efficiency improved.
