Definitions

  • the invention relates to scouring powders which at the same time offer a good cleaning action, in particular against greasy soiling, and develop only a little foam when used.
  • Scouring powder is one of the oldest and still indispensable cleaning agents that are used in households and businesses to remove stubborn dirt.
  • the basic constituents of scouring powders form, on the one hand, the abrasive particles required for the mechanical loosening of stubborn dirt and, on the other hand, surfactants as surface-active substances that are essential for the removal of greasy or greasy dirt.
  • the scouring powders currently on the market contain almost exclusively alkylbenzenesulfonates as surfactants, as well as occasionally other active ingredients and auxiliary substances such as.
  • German patent applications DE 25 39 733 A1 and DE 27 39 776 A1 describe liquid and powdered abrasives with an abrasive content of pearlite in an amount of up to 65%. These applications essentially focus on this special abrasive. Alkyl sulfates and alkylbenzenesulfonates are specified here as surfactants for the powdery compositions.
  • Canadian patent 1,048,365 (Procter & Gamble) describes abrasive powders with a high surfactant content of 20-35% and an abrasive content of 5-20%, which are recommended as both abrasive powder and dishwashing detergent.
  • Alkyl sulfates, alkylbenzenesulfonates and fatty alcohol ethoxylates are mentioned as surfactants.
  • the common known and currently commercially available abrasive powders have a good cleaning ability as a common feature greasy and fatty dirt, but foams to an undesirably high degree when used. In order to avoid foaming, an attempt was even made to offer pure abrasives without any added surfactants.
  • the object of the invention was therefore to provide the desired agents which combine the two product effects: good dirt removal and low foaming tendency.
  • this object was achieved by adding alkyl glycosides with a degree of oligomerization of 1.2 to 1.4 or surfactant combinations containing these alkyl glycosides to the scouring powders, which scouring powders may also contain conventional ingredients.
  • the invention therefore relates to low-foaming scouring powders containing abrasives, other customary constituents and optionally other surfactants, which are characterized in that they contain an addition of alkyl glycosides with a degree of oligomerization of 1.2 to 1.4.
  • Alkylglososides are known to be degradable surfactants of native origin.
  • the alkyl glycosides which can be used here as surfactants can be represented by the structural formula RO (G) x , where R is an aliphatic radical with at least 4 carbon atoms, in particular the radical of a primary alcohol and very particularly a fatty alkyl or fatty alkenyl radical with 8 to 22, preferably 12 to 18 carbon atoms.
  • R is an aliphatic radical with at least 4 carbon atoms, in particular the radical of a primary alcohol and very particularly a fatty alkyl or fatty alkenyl radical with 8 to 22, preferably 12 to 18 carbon atoms.
  • the symbol (G) in the formula stands for a glycose unit, glucose being preferred because of the technical availability on the one hand and the good reactivity on the other hand.
  • the index number x is any number between 1.2 and 1.4, which means the so-called degree of oligomerization, ie the distribution of monoglycosides and oligoglycosides is specified.
  • the alkyl glycosides are represented by the formula RO (G) x , the percentage of fatty alcohol is neglected. In principle, this fatty alcohol portion can largely be controlled by gentle distillative treatment of the alkyl glycoside, ie the excess fatty alcohol resulting from the reaction can be removed from the product except for residual values that are less than 1% total. They have been proposed for liquid manual dishwashing detergents, e.g. B.
  • alkylbenzene sulfonate As anionic co-surfactants, alkylbenzene sulfonate, soap, zwitterionic surfactants, amphoteric surfactants, alkane sulfonates, alpha-olefin sulfonates, alkyl sulfates, alkyl polyglycol ether sulfates and paraffin sulfonates and mixtures thereof are mentioned in particular.
  • the surfactant compositions described here are suitable for the production of products which foam strongly when used, such as, for example, manual dishwashing detergents and shampoos.
  • the description also mentions a possible addition of abrasive substances enumeratively, but no examples are available.
  • liquid, high-foaming cleaning agents for the manual cleaning of dishes are also known which, in addition to fatty alkyl glucosides with a degree of oligomerization of 1 to 1.4, serve as foam enhancers dialkyl sulfosuccinates with 7 to 9 carbon atoms in each of the alkyl residues contain. Again, there is no evidence of abrasives. It was therefore not foreseeable that this Alkyl glycosides alone or in combination with other surfactants in scouring powders show only a weak development of foam when used.
  • alkyl sulfates alkyl ether sulfates, alkyl benzene sulfonates, alkyl sulfonates, etc., which are common for cleaning agents, in question.
  • Alkyl sulfates which are prepared from natural oils and fats by known processes and have a saturated or unsaturated alkyl radical having 6-20, preferably 10-18 carbon atoms are preferred. Scouring powders which are free from alkylbenzenesulfonates are particularly preferred.
  • Suitable nonionic surfactants are fatty alcohol ethoxylates, ie adducts of 2-16 mol ethylene oxide onto fatty alcohols with branched or straight-chain saturated or unsaturated C16-C20-alkyl radicals.
  • Preferred fatty alcohol ethoxylates are those which are produced from natural fats and oils.
  • conventional amphoteric surfactants and betaines and / or amido betaines can also be used in small amounts. If this class of surfactants is also used, the amount used is based on the possible amount Align the presence of other surfactants so that the overall formulation has the desired foaming behavior.
  • All substances known for scouring powder e.g. B. mineral rock powders such as quartz, cristobalite, marble, pumice powder u. ⁇ . With a grain size up to 1 mm, preferably up to 0.3 mm, are used. The lower grain size is determined solely by the technical possibilities in the production of abrasive materials, also in the form of flour-like forms suitable for additions to polishing agents. Alternatively, plastic granules or powder as well as wood flour or glass beads and similar abrasives with a very mild abrasive effect can be used.
  • the known inorganic or organic compounds which provide H2O2 or active chlorine in the presence of water can be used as bleaching and disinfecting agents.
  • the per-compounds can be used together with so-called bleach activators, e.g. Tetraacetyl-ethylenediamine or tetraacetylglycoluril can be used.
  • scouring powders include inorganic or organic complexing agents and builders that are able to bind alkaline earth ions in the tap water that is used to apply the scouring powder and that lead to an increase in the cleaning effect with the surfactants.
  • This class of active ingredients includes the known zeolites and organic complexing agents, in particular the sodium salts of polycarboxylic acids, hydroxycarboxylic acids, aminocarboxylic acids, carboxyalkyl ethers, polyanionic polymers, in particular polymeric carboxylic acids.
  • P-containing complexing agents or builders should preferably not be used.
  • neutral or alkaline alkaline salts in particular sodium salts, from the group of chlorides, carbonates, bicarbonates, sulfates and silicates to the scouring powders.
  • the scouring powders according to the invention can also contain colorants and fragrances.
  • colorants and fragrances.
  • oxidative bleaching agents Known oxidation-stable color pigments such as phthalocyanine pigments or ultramarine and fragrances such as terpene compounds are selected.
  • the scouring powder can be prepared in a manner known per se, e.g. B. by drying part or all of the water-soluble components and admixing or spraying on the remaining components of the scouring powder.
  • the cleaning effect of the scouring powders according to the invention was tested according to the method published in the trade journal Seifen - ⁇ le - Fette - Wachsen, 112, 371 (1986).
  • the cleaning agent to be tested was placed on an artificially soiled plastic surface.
  • a mixture of petroleum jelly (R), fatty acid glycerol esters and pigments was used as artificial soiling.
  • the test area of 26 x 28 cm was evenly coated with 2 g of the artificial soiling with the aid of a surface coater.
  • a plastic sponge was soaked in tap water.
  • the scouring powder to be tested was applied to the test area as a 1: 1 mixture with tap water.
  • the sponge was then moved mechanically on the test surface. After ten wiping movements, the cleaned test area was kept under running water and the loose dirt was removed.
  • the cleaning effect, d. H. the whiteness of the plastic surface cleaned in this way was determined using a Microcolor color difference measuring device from Dr. Measured for a long time.
  • the clean white plastic surface served as the white standard.
  • the read values for the cleaned plastic areas are to be equated with the percentage of cleaning ability (% RV).
  • % RV percentage of cleaning ability
  • the foam behavior was checked in a practical manner using the following method, the foam which is produced when scrubbing being checked on a clean tiled table.
  • a commercially available scouring agent of the following composition was used as a comparison standard for the effects which can be achieved with the scouring powders according to the invention: 3.0% Na alkyl benzene sulfonate 3.0% Na hydrogen carbonate 1.3% K-peroxomonosulfate 0.3% Na sulfate 4.0% Na chloride Rest on 100% quartz flour The cleaning effect, which was determined with this agent according to the test method described, was equated with 100%. This product achieved the following marks in the foam test: Judging by 0 1 5 minutes grades 4th 3rd 2-3
  • the percentages in the following examples relate to% by weight of active substance.
  • Example 2 The same composition as example 2, but marble powder with a grain size of 0-0.2 mm was used instead of the plastic granulate. This agent had a similarly good cleaning performance and low foaming tendency as Example 2.
  • alkyl glucoside is used as the sole surfactant.
