Definitions
- DE-PS 23 27 describes 867 a washing process using a detergent with a combination of aliphatic polyethylene glycols from the group of ethoxylated C12 to C20 alcohols, alkanediols, amines, carboxylic acids, carbonamides or sulfonamides with degrees of ethoxylation from 2 to 6 and from 8 to 20 , wherein the mixing ratio of the low ethoxylated compound to the higher ethoxylated compound is 1: 5 to 2: 1.
- washing and washing aids for carrying out a washing process are known, the surfactant combination of 20 to 90 wt .-% anionic, zwitterionic or nonionic surfactants and 10 to 80 wt .-% of a fabric softener, which contains a fatty acid condensation product with a certain proportion of fatty acid partial glycerides, the fatty acid condensation product being prepared by reacting a triglyceride from higher fatty acids with a hydroxyalkyl polyamine.
- This detergent has both cleaning and fabric softening properties. The production of a detergent with particularly good detergency at low washing temperatures cannot be derived from this.
- the low ethoxylated aliphatic C12 to C20 alcohols can be natural or synthetically produced linear or branched, saturated or unsaturated alcohols with 12 to 20 carbon atoms, to which 2 to 6 moles of ethylene oxide have been added. Ethylene oxide adducts of fatty alcohols or oxo alcohols or combinations of fatty alcohols or oxo alcohols are generally used.
- Component a) can additionally or alternatively also consist of alkylphenol ethoxylates whose alkyl group contains 6 to 15 carbon atoms and to which 1.5 to 4 moles of ethylene oxide are attached.
- the higher ethoxylated aliphatic C12 to C20 alcohols are also derived from natural or synthetic alcohols with 12 to 20 carbon atoms, which may be linear or branched, saturated or unsaturated and to which 8 to 20 moles of ethylene oxide have been added per mole of alcohol.
- Component b) also or additionally comprises higher ethoxylated alkylphenols having 6 to 15 carbon atoms in the alkyl group to which 6 to 20 moles of ethylene oxide have been added.
- the weight ratio of component a): b) in the context of the present invention is in the range from 1: 0.5 to 1: 5.
- the stated combination of the nonionic surfactants with a low and a high proportion of ethylene oxide relates to combinations which consist both of low ethoxylated aliphatic alcohols with higher ethoxylated alkylphenols and also combinations of lower ethoxylated alkylphenols with higher ethoxylated alcohols. In any case, it is important that the combination contains low ethoxylated constituents and higher ethoxylated constituents in a ratio of 1: 0.5 to 1: 5.
- a condensation product which can be used according to the invention contains, for example, 2 to 20, preferably 5 to 15% by weight of diamide ester, 20 to 60, preferably 25 to 45% by weight of diamide, 5 to 40, preferably 10 to 35% by weight of monoamides, 5 to 40, preferably 10 to 30 wt .-% unreacted fatty acid triglyceride, the rest up to 100 wt .-% consists of free fatty acids, free amine, glycerin.
- a particularly suitable condensation product is obtained, for example, by reacting 1 mol of fatty acid triglyceride, preferably 1 mol of hardened beef tallow, corresponding to 3 mol of fatty acid residues and 1 mol of hydroxyethylethylenediamine, which is acidified, if desired, with an inorganic or with a non-surfactant organic acid.
- the reaction can be carried out until the reaction equilibrium is established; However, products in which the fatty acid condensation product makes up at least 50% by weight and preferably 60 to 90% by weight of the reaction product can also be used for technical purposes.
- the reaction product is cooled in a known manner and, if necessary, brought into a specific shape, for example flake shape or granule shape or powder shape.
- the reaction melt can also be mixed beforehand with a water-soluble non-surfactant organic or inorganic acid and the reaction product can be made slightly alkaline to slightly acidic.
- Suitable water-soluble organic or inorganic acids are, for example, acetic acid, oxalic acid, glycolic acid, lactic acid, citric acid, tartaric acid and hydrochloric acid, sulfuric acid or phosphoric acid. Glycolic acid is preferably used.
- the fatty acid condensation product is combined in the detergent according to the invention, in addition to the combination of low-ethoxylated and higher-ethoxylated alcohols or alkylphenols, with 5 to 60% by weight of other detergent constituents and, if appropriate, with anionic surfactants, but the amount of these is not more than the amount of the nonionic surfactants turn off.
- Suitable anionic surfactants are alkali metal or ammonium or amine salts of linear alkylbenzenesulfonates, alkanesulfonates, olefin sulfonates, alpha-sulfofatty acid ester salts and alkyl sulfates.
- the other detergent components that can be contained in the process product and combined with the condensation product include, for example, framework substances of the water-soluble inorganic phosphate type; Also suitable are alkali metal salts of aminopolycarboxylic acids, such as, for example, nitrilotriacetic acid, ethylenediaminetetraacetic acid; alkali salts are also suitable organic phosphonic acids, such as 1-hydroxyethane-1,1-diphosphonic acid, aminotrimethylene triphosphonic acid, ethylenediaminetetramethylenephosphonic acid, diethylenetriaminepentamethylenephosphonic acid; Also suitable are polymeric carboxylic acids, such as polyacrylic acid, polyhydroxyacrylic acid, and copolymers of maleic acid with vinyl methyl ether or acrylic acid; Insoluble builders are also suitable, such as the sodium aluminosilicates of type Zeolite A 4, which have recently been used increasingly as a phosphate substitute.
- alkali metal salts of aminopolycarboxylic acids such as,
- Suitable builders are sodium carbonate and sodium or magnesium silicate.
- Other common detergent ingredients are graying inhibitors, such as carboxymethyl cellulose, methyl cellulose, methyl hydroxypropyl cellulose, hydroxyethyl cellulose and ethoxylated starch.
- Alkali salts of saturated fatty acids with 12 to 22 carbon atoms and / or silicone oils and / or paraffins in amounts of up to 4% are suitable as foam inhibitors.
- Compounds which are generally derived from diaminostilbenedisulfonic acids are suitable as optical brighteners; but also derivatives of the diarylpyrazoline, aminocoumarin, distirylbiphenyl, thiophene type, each alone or in mixtures, can be used as optical brighteners.
- bleaching agent is often added to detergents, which preferably means active oxygen carriers, such as sodium perborate, sodium percarbonate, in each case alone or in combination with organic, peracid-forming n-acyl compounds, for example tetraacetylethylene diamine, tetraacetylglycoluril as bleach activators.
- active oxygen carriers such as sodium perborate, sodium percarbonate
- organic, peracid-forming n-acyl compounds for example tetraacetylethylene diamine, tetraacetylglycoluril
- H2O2-providing salts such as, for example, caroates, perbenzoates or peroxyphthalates, and also organic or inorganic active chlorine carriers, such as, for example, alkali metal hypochlorites, dichloro- or trichloroisocyanuric acid or their alkali metal salts, can be used as bleaching agents.
- the detergents according to the invention occasionally contain enzymes, with proteases and amylases resistant to alkali, perborate and surfactants being preferred. So much is used on proteases that there is a protease activity of 100 to 2500 LVE per gram of finished product, and so much is used on amylases that there is an amylase activity of 20 to 2,000 SKBE per gram of finished product.
- Powdered detergents can be prepared by first preparing the condensation product and then suspending it together with the other detergent constituents, insofar as they are heat-stable, into an aqueous suspension and then spray drying. The spray-dried product can then be mixed with the remaining ingredients such as bleaching agents, bleach activators, enzymes and fragrances. To produce liquid detergents, the condensation product, which is in molten or emulsified form, is worked into the preferably warm solution of the other constituents in water. The detergents according to the invention show significantly improved washing performance and controlled foaming behavior when used.
- Example 1 shows the production of a detergent according to the invention (Example 1) and the production of detergents according to the prior art (Example 2, without the addition of a condensation product) and the production of a further detergent according to the prior art without the addition of a condensation product and without addition a combination of nonionic surfactants, consisting of low ethoxylated and highly ethoxylated compounds (Example 3).
- Example 1 5% by weight of tallow fatty alcohol + 4 moles of ethylene oxide and 5% by weight of tallow fatty alcohol + 14 moles of ethylene oxide were sprayed onto the basic detergent of Example 1, as described in Example 1.
- washing tests were carried out in a 4 kg dry laundry household washing machine. Normally soiled household laundry and test fabrics with test soiling were used. The water hardness was 9 ° dH, the dosage in the two-eye washing process in the pre-wash and main wash was 80 g each.
- the whiteness (reflectance in%) of the washed test fabric was determined using an Elrephomat DFC 5 (Zeiss company) with a FL 46 filter and statistically evaluated. The following results were obtained: example Remission 1 69.3 2nd 64.7 3rd 60.9
