  • a tried-and-tested scouring cream contains marble flour as an abrasive and as an emulsifier or surfactant Laureth-7 (INCI name), which is often used as a surface-active substance in cosmetic products.
  • Laureth-7 is produced on the basis of lauric oils, which are mainly contained in coconut oil and palm kernel oil, whereby by chemical modification of lauric acid (C 12 H 24 O 2 ) laureth-7 (C 26 H 24 O 8 ) is produced.
  • lauric oils which are mainly contained in coconut oil and palm kernel oil, whereby by chemical modification of lauric acid (C 12 H 24 O 2 ) laureth-7 (C 26 H 24 O 8 ) is produced.
  • lauric acid C 12 H 24 O 2
  • laureth-7 C 26 H 24 O 8
  • PEG-4 Rapeseedamide (INCI name) used on the basis of technical rapeseed oil on the market and is not in competition with food.
  • the IUPAC name of this product is rapeseed oil amines, N- (hydroxyethyl) -, ethoxylated.
  • Marble flour is used as the abrasive in combination with PEG-4 rapeseedamides.
  • a preferred scouring agent contains 1.0 to 5.0% by weight, preferably 1.5 to 3.5 and especially about 2.0% by weight, of PEG-4 rapeseedamides containing about 40% by weight of marble flour in water.
  • the surface-active substances based on monounsaturated and polyunsaturated C18-alkyl chains behave stably even without the special addition of stabilizers such as antioxidants, complexing agents and UV filters when the scouring agent is marketed in opaque plastic packaging.
  • stabilizers such as antioxidants, complexing agents and UV filters
  • abrasives which are marketed in fully transparent bottles, preferably in PET and rPET, the addition of stabilizers in different types and amounts depending on the type of detergent or cleaning agent required.
  • Preferred antioxidants are vitamin C (ascorbic acid) and derivatives (eg ascorbyl palmitate), vitamin E (D, L-tocopherol) and derivatives (eg tocopheryl acetate), tocotrienols, but also synthetic ones such as BHT (butylhydroxytoluene) and BHA (butylhydroxyanisole) etc. known to those skilled used.
  • Preferred complexing agents are especially biodegradable, such as ethylenediamine disuccinic acid (EDDS, Enviomet C 140 from Fa, Innospec)), L-glutamic acid, N, N-diacetic acid (GLDA, Dissolvine GL 47S from Fa, Akzo-Nobel), Methylglycine diaceticacid (MGDA, Trilon M from Fa. BASF). It can also classic non-degradable complexing agents such as EDTA and NTA u.a. known to those skilled used.
  • EDDS ethylenediamine disuccinic acid
  • GLDA N-diacetic acid
  • MGDA Methylglycine diaceticacid
  • UV filters are benzophenones, for example 2-hydroxy-4-methoxybenzophenone-5-sulfonic acid (Uvinul MS 40 from BASF), cinnamates such as ethylhexyl p-methoxycinnamate, p-aminobenzoic acid (PABA) derivatives and the like known, used.
  • benzophenones for example 2-hydroxy-4-methoxybenzophenone-5-sulfonic acid (Uvinul MS 40 from BASF)
  • cinnamates such as ethylhexyl p-methoxycinnamate, p-aminobenzoic acid (PABA) derivatives and the like known, used.
  • PABA p-aminobenzoic acid
  • a scrubbing agent with 40% by weight of marble flour and only 2.0% by weight of PEG-4 Rapeseedamide has a very high viscosity at very low shear rates or at rest.
  • the liquid scouring agent is particularly storage-stable over many months and even at extreme temperatures up to 60 ° C. At shear rates, as they occur when pouring out of a bottle at the bottleneck, results in a relatively steep drop in viscosity, so that the scouring agent low viscosity appears.
  • a scouring agent according to the invention achieves at least the values of a known scouring milk.
  • high viscosity alone does not guarantee long-term storage stability, but at most results in a tendency to settle which is more delayed in time, it can be assumed that the yield point in the abrasives according to the invention is high.
  • the combination of marble dust abrasive and PEG-4 rapeseedamides, in addition to the shear thinning behavior points to elastic fractions which, at very low shear rates, yield a flow limit otherwise known only from typical polysaccharides, such as xanthan gums, but have the disadvantage that they pull threads and are badly rinsable from surfaces.
  • This rheological behavior of a scrubbing agent according to the invention is completely atypical and surprising for viscous mixtures at such low use concentrations of the surface-active substances on the order of about 2.0% by weight.
  • the scrubbing agent according to the invention reproduced below as an exemplary embodiment combines a perfect suspension behavior for particles with high density (density of CaCO3: 2.7 kg / l), which generally otherwise tend to settle strongly under the action of gravity, with a perfect flow behavior under shear stress, the the scouring agent appears to flow very easily when used.
  • the suggested preferential attachment of PEG-4 rapeseedamide molecules to the surface of the CaCO3 particles as an interface instead of the formation of micelles is also due to the relatively low HLB value of PEG-4 rapeseedamides of about 11. This does not happen either On the other hand, the HLB value of 11 is ideally suited to emulsify fat and oily impurities and, above all, hydrophobic lime soap residues from surfaces to be cleaned to remove.
  • the sensorially found subjective viscoelastic behavior of a scrubbing agent according to the invention, in which a time-dependent shear thinning exists, can also be termed thixotropic.
  • the content of surface-active substance in the form of PEG-4 rapeseedamides in a scouring agent can be in the range from 0.1 and from 1.0 to about 5.0% by weight. Preferably, a range of about 1.5 to about 3.5 wt .-% and in particular about 2.0 wt .-% is provided.
  • a commercially available scouring cream generally also contains dyes, fragrances and perfumes and the like in order to make use more pleasant.
  • a preferred embodiment of a scouring agent according to the invention contains: Calcium carbonate CaCO3 (marble powder) 40.00% by weight PEG-4 Rapeseedamide 2.00% by weight phenoxyethanol 1.00% by weight
  • the ratio of abrasive and PEG-4 rapeseedamides is 20 to 1% by weight. In the present invention, this ratio may be in the range of 10 to 1 to 30 to 1% by weight.
  • the proportion of calcium carbonate can be in the range from about 20.0% by weight to about 50.0% by weight.
  • a formulation of this type has a clearly viscoelastic behavior, according to which in the resting phase, the scouring agent is extremely highly viscous. As soon as shearing forces act on the formulation, it becomes low viscous. This behavior leads to positive performance characteristics in that the formula is very easy to disperse and rinse off, which means that less water is used compared to a conventional scouring cream.
  • the scouring agent barely foams so that it can be filled immediately after production. Compared to the previously used scrubbing milk with Laureth-7 as nonionic surfactant no anti-foam additives are needed.
  • PEG-4 rapeseedamide is particularly readily biodegradable.
  • a liquid scouring agent according to the invention with calcium carbonate as abrasive can contain not only the additives contained in natural calcium carbonate, but also small quantities of other common abrasives insofar as this does not impair the properties described with respect to stability and flow behavior due to calcium carbonate.
  • a scouring agent according to the invention not only achieves the scrubbing milk previously used with regard to the particularly high demands on stability, but above all it also improves the rinsability of product residues. Added to this are the advantages of significantly improved producibility with shorter production cycles in the batch process.
  • PEG-4 rapeseedamide may also be used in a detergent or cleaning agent in the range of 0.1% to 5.0% by weight.
  • a detergent preferably 1.0 wt .-% to 3.0 wt .-% PEG-4 Rapeseedamide be used and in particular 1.5 wt .-%.
  • a hand dishwashing detergent it is preferred to use 0.5% by weight to 2.0% by weight of PEG-4 rapeseedamides and in particular 1.0% by weight.
  • a universal all-purpose cleaner preferably 1.0 wt .-% to 3.0 wt .-% PEG-4 Rapeseedamide be used and in particular 1.5 wt .-%.
  • a WC cleaner preferably 0.1 wt .-% to 1.0 wt .-% PEG-4 rapeseedamides are used, in particular about 0.5 wt .-% and preferably 0.11 wt .-%.
  • a hygiene cleaner preferably 0.1 wt .-% to 1.0 wt .-% PEG-4 Rapeseedamide be used, in particular ca, 0.5 wt .-% and preferably 0.11 wt .-%.
  • a known universal all-purpose cleaner can be used instead of 1.5 wt .-% of nonionic surfactant based on saturated C12 to C14 alkyl chains preferably about 1.5 wt .-% PEG-4 rapeseedamides, preferably as the antioxidant tocopherol of 0.01 wt .-% is used.
  • the additional proportion of PEG-4 rapeseedamides to conventional surfactants results above all in an improvement in the cleaning power with respect to oil and fat. This is due to a relatively low HLB value, as is the case with the abovementioned abrasive.
  • the additional amount of PEG-4 rapeseedamides leads to synergisms with classical surfactants with saturated C12 to C14 alkyl chains, which lead to an improvement in the cleaning effect.
  • conventional synthetic surfactants can be used in conventional detergents or cleaners are surfactants with predominantly saturated C12 to C14 alkyl chains.
  • about 5 to 10% by weight of the total surfactant content of about 15 to 20% by weight of a washing or cleaning agent is replaced by PEG-4 rapeseedamides.
  • a known all-purpose cleaner based on acetic acid in addition to customary nonionic and anionic surfactants based on saturated C 12 to C 14 alkyl chains, preferably about 0.5% by weight, in particular 0.11% by weight, of PEG-4 rapeseedamides can be used is preferably used as the antioxidant ascorbic acid of 0.02 wt .-%.
  • a toilet cleaner based on acetic acid in addition to conventional anionic surfactant based on saturated C12 to C14 alkyl chains preferably about 0.5, in particular 0.11 wt .-% PEG-4 Rapeseedamide be used, preferably as the antioxidant ascorbic acid of 0.025 wt .-% is used.
  • the ratio of PEG-4 rapeseedamides used to antioxidant may range from about 3 to about 200, preferably from about 4 to 5, and from about 150 as in the above general-purpose universal cleaner.
