Definitions

• the present invention relates to a mild detergent with 5 to 30% by weight of at least one surfactant, 5 to 60% by weight of a builder and conventional washing aids.
• sodium silicates often in conjunction with soda, were used as builders in detergents, although in the course of modern detergent development they were replaced by substances with better builder properties, for example condensed phosphates.
• zeolite A is often used as the basic builder in detergents in conjunction with polycarboxylates.
• a detergent is known from DE-OS 4o o4 626, which contains an amorphous sodium disilicate with a water content of 0.3 to 6% by weight as a builder.
• Delicates are generally characterized by a low pH compared to general-purpose detergents, which they impart to the wash liquor, and contain no bleach.
• the mild detergent according to the invention contains 5 to 60% by weight of Kanemite as a builder.
• test detergents were produced by the spray-mixing method by premixing their powdery constituents in a free-fall mixer and then spraying the liquid constituents onto the dry premix (see “soaps, greases, oils, waxes” 99 (1973) , Pages 351 to 357).
• Examples 11 to 13 of Table 1 show the composition of mild detergents on the market, as far as is known.
• the washing tests were carried out in a punch-card controlled household washing machine (type Miele TMT) under the following conditions:
• Table 2 shows the washing results obtained with the mild detergents according to Examples 1 to 13, the primary washing action being the sum ⁇ RD [%] of the single reflectance differences obtained with the seven test tissues RD [%] are given, while the secondary washing effect shows the total of all ashes ⁇ ashes [%], which is composed of the individual values of the five test fabrics used. Finally, the pH values are given, which were measured in the wash liquor after a watering time of 15 minutes.
• Anionic surfactants are understood as meaning water-soluble salts of higher fatty acids or resin acids as well as higher alkyl-substituted aromatic sulfonates, for example alkylbenzenesulfonates with 9 to 14 C atoms in the alkyl radical (LAS).
• LAS alkyl radical
• Nonionic surfactants are to be understood as 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 etheroxylates), 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 Washing auxiliaries include weakly acidic, neutral or alkaline inorganic or organic salts, for example bicarbonates or carbonates of the alkalis and alkali salts of organic, non-capillary-active, 1 to 8 carbon atoms containing sulfonic acids, carboxylic acids and sulfocarboxylic acids.
• Washing aids are also alkali or ammonium salts of sulfuric acid, boric acid, alkylene, hydroxyalkylene or aminoalkylenephosphonic acid.
