Definitions

• the present invention relates to liquid detergents with an excellent softening and lightening effect which, in contrast to most commercial detergents, are practically free of anoinic surfactants and anionic whiteners.
• detergent is to be understood in the broadest sense within the scope of this invention. It includes a wide range of cleaning agents as well as fabrics and household detergents as well as laundry aftertreatment agents. Use as a "one-step" household detergent and dishwashing detergent is preferred.
• nonionic surfactants for example the addition products of ethylene oxide with higher aliphatic alcohols with 6 to 50 and C atoms, polyoxyalkylene esters of organic acids such as higher fatty acids, resin acids, tall oil acids and acids of the oxidation products of petroleum, and alkylene oxide adducts of higher fatty acid amides, the fatty acid part generally having 8 to 22 carbon atoms and being condensed with 10 to 50 mol of ethylene oxide.
• the liquid medium for the detergents according to the invention is aqueous and can be made from water alone or from water and there are additional solvents for certain additives.
• the additional solvents can make up up to 20, preferably up to 15% of the total solvent content.
• the following are suitable: low alkanols or a low diol or polyol.
• the liquid detergent according to the invention can also contain customary additives, such as dirt suspending agents or graying inhibitors, foam inhibitors, preservatives, and perfumes. These are of course chosen so that they are compatible with the main components of the detergent.
• the nonionic surfactants are used in amounts of 5 to 80% by weight, preferably 20-60% by weight.
• concentration of the fabric softener is 1 to 30% by weight, preferably 5-20% by weight.
• the aqueous solvent, preferably water, which may also contain mono-, di- and polyhydric alcohols and similar solvents, is represented by 5 to 60% by weight.
• the whiteners to be used according to the invention are added in amounts of 0.005 to 1% or more, based on the weight of the detergent. Washing / treatment liquors that contain the claimed detergent give a brilliant aspect and a pleasant feel when washing textiles made of preferably cellulose and / or polyamide fibers.
• the diarylpyrazoline type optical brighteners have the following formula:
• Ar and Ar ' are aryl radicals, such as phenyl, diephenyl or naphthyl, which can carry further substituents, such as hydroxyl, alkoxy, hydroxyalkyl, amino, alkylamino, acylamino, carboxyl, sulfonic acid and sulfonamide groups or Halogen atoms.
• the brighteners to be used are preferably free of ionic groups. They are generally known and are described, for example, in the following patent literature: GB 669 589, 669 490, 669 591, 883 826, US 2 879 174, DE 1 023 445, 1 104 483, 1 080 963, CH 415 535, FR 1 354 629, BE 629 875.
• the detergent according to the invention can be used in soft or hard water at a higher temperature.
• the washing treatment is carried out, for example, as follows:
• the textiles are treated for 1 to 30 minutes at 20 to 100 ° C. in a washing bath which contains 0.1 to 10 g / kg of the detergent.
• the liquor ratio can be 1: 3 to 1:50.
• a liquid detergent was made as follows: 0.1 parts of the white toners I-XII were in 5.5 parts of ethanol dissolved or dispersed and with 18 parts of ethoxylated C12-C14 fatty acid (10 ⁇ O) 5 parts of ditallow fatty alkyl dimethyl ammonium chloride and about 71.5 parts of demineralized water to 100.
• the washed rags were rinsed, dried and ironed.
• the reflectance of the white tint obtained was measured with a spectrophotometer (FRC3 from Zeiss) and the degree of whiteness calculated according to Berger.
• a nonionic / anionic liquid detergent was made as follows:
• This mixture was after adding 2 parts of triethanolamine 11 parts of ethanol 47 parts of demineralized water and 20 parts linear alkanesulfonate (as triethanolamine salt) homogenized by stirring.
