Definitions
- the present invention relates to a pasty, phosphate-free detergent, which is particularly suitable for washing heavily soiled work clothes, for example contaminated with mineral oil, and does not develop any disruptive amounts of foam when used in automatic washing machines.
- the agent should also work under particularly critical conditions, i.e. Even when using softened water, as is usually used in commercial laundries, foam only insignificantly both in the main wash cycle and in the post-rinse phase, so that there are no malfunctions in the automatic washing systems.
- Powdered detergents are known from European patent application EP-A-0 273 377, which contain small amounts of alkylbenzenesulfonate, at least 2 different ethoxylated alcohols, zeolite, anhydrous soda in amounts of 40 to 60% by weight, sodium silicate in amounts of 2 to 7 % By weight and water-soluble polymers with graying-inhibiting action. These agents are suitable for washing heavily soiled work clothing.
- Pasty detergents in particular those with a high content of strongly alkaline constituents, such as sodium metasilicate or soda, have the advantage over powdery detergents that they can be handled and dosed without dust. They are particularly suitable for automatic dosing devices. Their problem is that they must be sufficiently flowable over a wide temperature range, which considerably limits the freedom from recipes, especially when high proportions of solid active ingredients are to be incorporated into the paste. It is also required that the agents do not separate during storage. Furthermore, the aim is to avoid solvents and suspension stabilizers to use because they do not contribute to the washing performance when used.
- Component (B) has 12 to 15 carbon atoms in the alcohol residue and can be derived from native or synthetic alcohols (oxo alcohols).
- the latter usually consist of a mixture of linear and methyl-branched alcohols in the 2-position, the proportion of linear alcohols being said to predominate.
- Component (C) is derived from the same alcohols or alcohol mixtures as component (B).
- the proportion of C12 alcohol in the alcohol residues of components (B) and (C) is preferably not more than 50% by weight and the total content of the agents in ethoxylated C16-C18 alcohols is not more than 2 % By weight, in particular less than 1% by weight.
- Component (D) consists of sodium silicate, which has a Na2O: SiO2 ratio of 1: 0.8 to 1: 1.5, preferably 1: 0.9 to 1: 1.1.
- the sodium silicate is used as an anhydrous salt.
- Nonionic or anionic polymers with a graying-inhibiting effect serve as constituent (F).
- Cellulose ethers such as Na-carboxymethyl cellulose and their are particularly suitable Mixtures with other cellulose ethers, such as methyl cellulose, ethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose or mixed ethers, such as methyl hydroxyethyl cellulose, methyl carboxymethyl cellulose or ethyl hydroxyethyl cellulose.
- Suitable polymers are polyacrylic acid, copolymers of acrylic acid and vinyl ethers, copolymers of acrylic acid and vinyl ethers, copolymers of acrylic acid and maleic acid (Sokalan (R) ) in the form of the sodium salts and other known copolymers of acrylic acid with copolymerizable olefinic compounds.
- Cellulose ethers and synthetic polymers can also be used together. Mixtures of carboxymethyl cellulose with methyl cellulose or methyl hydroxyethyl cellulose have proven to be particularly useful.
- Component (E) consists of at least one complexing agent from the class of nitrilotriacetic acid (NTA) and the polyphosphonic acids in the form of the sodium salt, such as ethylenediamine-tetramethylenephosphonic acid (EDTMP), diethylenetriamine-pentamethylenephosphonic acid (DTPMP), aminotrimethylenephosphonic acid (ADTMPy) and in particular 1 -1,1-diphosphonic acid (HEDP).
- the agent preferably contains 3 to 6 NTA (Na salt) and 0.5 to 2% by weight of HEDP (Na salt).
- Enzymes, fragrances and customary optical brighteners are possible as further non-surfactant components (G) which do not act as builders, in particular optical brighteners with substantivity for cellulose fibers (cotton) in proportions of 0.05 to 0.5% by weight.
- the water content of the agents should be as low as possible, since free water increases the viscosity of the agents and thus complicates the processing and metering of the agents. Water contents of 2% by weight or less are therefore particularly preferred.
- the agents are produced by mixing and homogenizing the solid, finely divided constituents with the liquid nonionic surfactants (components B and C). Surprisingly, it was found that about half of the solid alkylbenzenesulfonates behave like liquid constituents and thus favor the incorporation of high solids contents.
- the mixture is then expediently ground, for example in a colloid mill or on a roller mill, so that the grain size of the suspended solids is between 5 and 80 »m, preferably 10 to 50» m.
- the proportion of coarse particles (over 80 »m) should preferably be below 10% by weight.
- the agents are generally used in a concentration of 5 to 12 g / l, preferably 8 to 10 g / l, with softened water, ie softened to a degree of hardness of less than 2 ° dH, in particular less than 1 ° dH, for Preparation of the wash liquor is used.
- softened water ie softened to a degree of hardness of less than 2 ° dH, in particular less than 1 ° dH, for Preparation of the wash liquor is used.
- a detergent of the following composition was tested.
- the nonionic surfactants B and C were derived from oxo alcohols of chain length C12-C15.
- EO means attached ethylene oxide.
- Component (F) consisted of a 2: 1 mixture of sodium carboxymethyl cellulose and methyl hydroxyethyl cellulose (hydroxyethyl content 0.8% by weight).
