Definitions
- Detergents which should also be suitable for the gentle cleaning of highly sensitive textiles made of wool or silk, are known per se. They generally react neutral to weakly alkaline and, in addition to synthetic anionic surfactants such as alkyl i benzene sulfonate, fatty alcohol sulfate or alkyl glycol ether sulfate, often also contain nonionic or cationic compounds.
- the nonionic surfactants are said to increase cleaning ability, while the cationic compounds are said to improve the softness and feel of the washed fabrics.
- detergents which contain only alkylbenzenesulfonate as a synthetic anionic surfactant can impair the fiber structure of sensitive washable types of wool, in particular merino and angora wool, when used repeatedly, e.g. Wash fatty alcohol sulfates insufficiently at the necessary low washing temperatures.
- non-ionic surfactants have also proven to be less favorable, since sensitive wool textiles washed with them feel comparatively hard and brittle. These effects can increase considerably when used in washing machines.
- the addition of softening cationic surfactants, as recommended for such purposes can only partially compensate for the loss of grip and, in the presence of anionic surfactants, leads to a decrease in washing power.
- Component (a) is derived from fatty alcohols or fatty alcohol mixtures of natural or synthetic origin, which can be linear or optionally methyl-branched in the 2-position (oxo radical).
- Suitable fatty alcohols are primarily lauryl, myristyl, cetyl and stearyl alcohol and mixtures thereof.
- the statistical average is expediently C 12 -C 14 '.
- the statistical average of ethylene glycol ether groups is 1 to 3, preferably 2, ie, as is customary in industrial alkoxylation, even small amounts of non-ethoxylated alcohols or ethoxylates with more can are present as 3 glycol ether groups.
- the sulfuric acid half-esters produced by sulfation from these alkyl (poly) glycol ethers are in the form of the sodium salt.
- the proportion of the agents in this surfactant component is preferably 7 to 13% by weight and in particular 8 to 12% by weight.
- component (b) Sodium alkylbenzenesulfonate with linear alkyl chains containing 10 to 14 carbon atoms is used as component (b). Sodium dodedylbenzenesulfonate is preferably used. The proportion of the component is 15 to 22% by weight, preferably 16 to 20% by weight. The total amount of components (a) + (b) should be 20 to 30% by weight.
- Component (c) is derived from fatty acids of natural or synthetic origin, preferably from natural fatty acid mixtures, such as coconut fatty acids (after the fraction having less than 12 carbon atoms has been separated off). Suitable mixtures can e.g. Contain lauric, myristic, palmitic, stearic and oleic acid, however the proportion of saturated C12-C14 fatty acids should be at least 50 mol% and preferably at least 60 mol%.
- the fatty acid monoethanolamides which are produced by reaction with monoethanolamine, should not contain any free ethanolamine and should react essentially neutrally.
- component (c) is preferably 1 to 3% by weight and in particular 1.2 to 2.5% by weight,
- the total amount of components (a) + (b) should be 20 to 30% by weight, preferably 23 to 28% by weight, and the weight ratio of components (a) + (b) to component (c) should preferably be 4: 1 up to 10: 1.
- Component (d) consists of an organopolysiloxane which is present in a mixture with 1 to 10% by weight, based on component (d), of a finely divided, preferably silanized silica and an emulsifier with which a homogeneous distribution of the organopolysiloxane in water or the water-containing mixture of components (a), (b) and (c).
- Dimethylpolysiloxanes which are present in a mixture with silanized silica and nonionic emulsifiers are particularly useful.
- Suitable emulsifiers are e.g. Polyglycol ethers which are substituted by longer-chain alcohols, alkylphenols, fatty acids and fatty acid amides.
- High molecular weight unsubstituted polyglycol ethers as well as block polymers of polyethylene glycol and polypropylene glycol and mixtures of the aforementioned emulsifiers are also suitable.
- the mixtures of dimethylpolysiloxane, silica and emulsifier are commercially available as ready-made products.
- non-surfactant or non-alkaline detergent additives such as colors and fragrances
- preservatives e.g. Formalin
- complexing agent for traces of heavy metals e.g. Ethylene diaminotetraacetate
- low molecular weight carboxylic or polycarboxylic acids for adjusting the pH and means for adjusting the viscosity of the aqueous concentrate, such as lower alcohols, glycerol or glycol ethers and neutral salts, such as sodium chloride.
- the proportion of these components is less than 1% by weight, usually less than 0.5% by weight. Their total amount should not exceed 5% by weight.
- the detergents used are in the form of aqueous, storage-stable concentrates. In this form, they can be dosed particularly easily or distributed homogeneously in the washing solution. You can can be used both for manual washing and for washing in the washing machine, machine washing being preferred, especially since the design of the agent is especially coordinated for this purpose.
- the agents are suitable for washing highly sensitive textiles, in particular knitted fabrics made of wool and silk, including sensitive angora wool. These textiles do not become hard when achieving a very good cleaning result, but keep their natural fluffiness and their light and loose feel not only when hand washing, but also when washing in washing machines (washing machines) in the so-called wool washing program.
- the mechanical processing of the textile goods in the washing machine should be comparatively low when the fleet is high, which is generally guaranteed in washing machines with special wool washing programs.
- the washing temperature is preferably 25 to 35 ° G and the liquor ratio is preferably 1:25 to 1:50.
- Foam problems i.e. Foaming of the washing solution or strong after-foaming after rinsing with water do not occur.
- the washing treatment in the washing machine was carried out in a washing machine of the trade with a horizontal drum using the wool washing program.
- Foaming was moderate, i.e. the space above the liquid level was about half filled with foam. Foaming during rinsing was very low in the first rinse cycle and did not occur in the second and third rinse cycle.
- the test for wool seal quality was carried out according to the test method published by the International Wool Secretariat (test method - No. 240).
- the sign "+" means quality of the wool seal.
- 4 wool detergents from the trade were used.
- Agent I contained 19% nonionic surfactant (fatty alcohol polyglycol ether) and 4% dimethylditalgalkylammonium chloride.
- Agent II contained 23.5% nonionic surfactant (fatty alcohol polyglycol ether) and 2.5% quaternary ammonium salt (plasticizer).
- Agent III contained 15% alkylbenzenesulfonate and 7% nonionic surfactant (fatty alcohol polyglycol ether).
- Agent IV contained 12.5% alkylbenzenesulfonate, 7.5% fatty alcohol diglycol ether sulfate, 1% fatty acid diethanolamide and 1% ampholytic surfactant in addition to small amounts of sodium pyrophosphate.
