Definitions

Modern detergents consist of several substances that fulfill different functions. So builders are used to remove the natural water hardness in the wash liquor, tensides to remove dirt and bleaching systems, which are protected by stabilizers, to oxidatively destroy dirt and germs.
sodium percarbonate sodium percarbonate
Sodium percarbonate sodium percarbonate
Sodium percarbonate can only be used in water-free, at least low-water detergent formulations, which, however, require special production technologies and raw materials.
Kanemit / NaPC has good storage stability due to the direct contact of the sodium percarbonate with the Kanemit.
Kanemit / NaPC Because of the optimal distribution of active oxygen on the Kanemitparticles, Kanemit / NaPC has no fire-promoting properties, like an investigation according to the UN regulation "Test for fire-promoting properties" (cf. "Recommendations on the Transport of Dangerous Goods", 8th edition, United Nations , New York, 1993). Therefore Kanemit / NaPC is not to be classified in classes 4.1, 4.2 and 5.1 according to the transport regulations.
the surprisingly good bleaching effect is probably due to the special particle structure of the Kanemit / NaPC ago.
the sodium percarbonate formed in situ is adsorbed on the kanemite in very fine distribution, the small particle size of the adsorbed sodium percarbonate resulting in a particularly high bleaching rate and bleaching yield.
the dispersing effect of the Kanemit in the Kanemit / NaPC system is of crucial importance for the reduction of the mechanical loss in the washing machine, whereby mechanical loss refers to the proportion of poorly soluble or heavy bleach particles that sink to the bottom of the washing machine or in their pump connections remain and therefore do not contribute to the active washing process.
the detergent according to the invention also shows a surprisingly low tendency towards incrustation.
the good flowability of the detergent according to the invention is a further advantage, the fine distribution of the sodium percarbonate on the kanemite particles obviously preventing the sodium percarbonate particles from growing together and thus caking during storage.
the detergent according to the invention can contain anionic surfactants ("Anionics”) and / or nonionic surfactants (“Nonionics”).
Anionic surfactants are to be understood as meaning the water-soluble salts of higher fatty acids or resin acids, such as sodium or potassium soaps from coconut, palm kernel or turnip oil, and from tallow and mixtures thereof.
Other suitable anionic surfactants are secondary linear alkane sulfonates and ⁇ -olefin
Nonionic surfactants are understood to mean those compounds which have an organic, hydrophobic group and a hydrophilic radical, for example the condensation products of alkylphenols or higher fatty alcohols with ethylene oxide (fatty alcohol ethoxylates), the condensation products of polypropylene glycol with ethylene oxide or propylene oxide, the condensation products of Ethylene oxide with the reaction product of ethylenediamine and propylene oxide, as well as long-chain tertiary amine oxides
surfactants with a zwitterionic (ampholytic) character include the following compounds: Derivatives of aliphatic, secondary and tertiary amines or quaternary ammonium compounds with 8 to 18 carbon atoms and a hydrophilic group in the aliphatic radical, such as sodium 3-dodecylaminopropionate, sodium 3-dodecylaminopropanesulfonate, 3- (N, N-dimethyl-N hexadecy
Inorganic salts, organic acids and their salts and complexing agents are suitable as auxiliary washing agents.
Useful inorganic salts include the bicarbonates or carbonates of the alkalis, e.g. Soda.
Organic washing aids include sulfonic acids, carboxylic acids and sulfocarboxylic acids containing 1 to 7 carbon atoms and their salts.
benzene, toluene or xylene sulfonic acid, sulfoacetic acid, sulfobenzoic acid, sulfodicarboxylic acids, acetic acid, lactic acid, citric acid and tartaric acid and their salts are to be emphasized.
the complexing agents include, for example, nitrilotriacetic acid, ethylenediaminetetraacetic acid, N-hydroxyethylethylenediaminetriacetic acid or polyalkylenepolyamine-N-polycarboxylic acids.
Washing aids also include alkali or ammonium salts of sulfuric acid (e.g. Na2SO4), boric acid, alkylene, hydroxyalkylene or aminoalkylenephosphonic acid, methylenediphosphonic acid, 1-hydroxyethane-1,1-diphosphonic acid and nitrilotrismethylenephosphonic acid.
sulfuric acid e.g. Na2SO4
boric acid alkylene, hydroxyalkylene or aminoalkylenephosphonic acid, methylenediphosphonic acid, 1-hydroxyethane-1,1-diphosphonic acid and nitrilotrismethylenephosphonic acid.
Washing aids that increase the dirt-carrying capacity of washing liquors such as carboxymethyl cellulose, carboxymethyl starch and methyl cellulose, foam regulators, such as mono- and dialkyl phosphoric acid esters with 16 to 20 carbon atoms in the alkyl radical, and optical brighteners, disinfectants and enzymes, such as proteases, amylases, lipases, and also fragrances, can also be components.
the detergents listed in the following examples were produced by the spray mixing method.
a free-fall mixer was used, in which the solid powdery ingredients were premixed, while the liquid ingredients were then sprayed onto the dry premix (see “Soaps, Fats, Oils, Waxes", Volume 99, pages 351 to 357, 1973).
the fabric deposits were determined in the form of the average inorganic fabric ash (average of 5 test fabrics) as a percentage of the residue on ignition at 800 ° C.
Test fabric Wa I [%] Wa II [%] Wa III [%] WFK cotton 3.8 3.2 2.8 WFK polyester / cotton 2: 1 2.4 2.0 1.6
the mixture of partially hydrated kanemite (70% by weight) with sodium percarbonate (30% by weight) absorbed in the finest distribution on the surface of the detergent Wa III according to the invention was obtained by the process of DE-OS 42 23 546.
a sodium silicate consisting essentially of ⁇ -Na2Si205 was added in aqueous solution to saturation with CO2 and then H202 added.
the amounts of the individual components had previously been calculated to the desired composition described above.
