摘要:
Phosphate-free automatic dishwashing agents containing a) citrate, b) sodium percarbonate, c) nonionic surfactant, d) copolymer encompassing i) monomers from the group of the mono- or polyunsaturated carboxylic acids, ii) monomers of the general formula R1(R2)C═C(R3)—X—R4, in which R1 to R3, mutually independently, denote —H, —CH3, or —C2H5, X denotes an optionally present spacer group that is selected from —CH2—, —C(O)O—, and —C(O)—NH—, and R4 denotes a straight-chain or branched saturated alkyl residue having 2 to 22 carbon atoms or an unsaturated, preferably aromatic residue having 6 to 22 carbon atoms, e) 0.05 to 1 wt % methylglycinediacetic acid, are notable for washing and rinsing results that are comparable or even superior to those of phosphate-containing automatic dishwashing agents.
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:
Phosphate-free, bleaching agent-containing dishwasher detergents which contain a) citrate, b) bleaching catalyst selected from the group consisting of the bleach-boosting transition metal salts and transition metal complexes, c) copolymer(s) which comprise i) one or more acid group-containing monomer, ii) one or more additional hydrophobic monomer. The detergents have an improved bleaching action.
摘要:
Liquid, low-alkaline and bleach-free dishwasher detergent having a pH value (20° C.) of 8 to 12 and containing: a) 10 to 60 percent by weight of a builder; b) more than 1.5 percent by weight of a phosphonate; c) 0.1 to 20 percent by weight of an anionic copolymer comprising: i) unsaturated carboxylic acid(s) and ii) sulfonic acid group-containing monomer(s). Detergents according to the invention exhibit a good cleaning power on bleachable dirt, particularly tea stains.
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.
