摘要:
A water-free surfactant composition containing: (a) a fatty alcohol sulfate corresponding to the formula R.sup.1 O--SO.sub.3 X, where R.sup.1 is a linear alkyl chain, and X is an alkali metal, alkaline earth metal, ammonium, alkyl ammonium, alkanolammonium or glucammonium; and (b) an alkyl benzenesulfonate corresponding to the formula R.sup.2 --Ph--SO.sub.3 X where R.sup.2 is an alkyl chain containing 10 to 14 carbon atoms, Ph is a phenyl group and X is alkali metal, alkaline earth metal, ammonium, alkyl ammonium, alkanolammonium or glucammonium. The fatty alcohol sulfate and alkyl benzenesulfonate are present in the surfactant composition in a weight ratio of 50:50 to 90:10. The water-free surfactant composition provides a reduced potential for irritation, good flow behavior and solubility in cold water. The surfactant composition is useful in laundry detergents, dishwashing detergents and cleaners.

摘要:
A process for stabilizing an aqueous zeolite suspension by adding to the suspension at least one nonionic surfactant comprising an alkyl or alkenyl glycoside of the formula R.sup.3 O--(G).sub.x in which R.sup.3 is an alkyl or alkenyl group containing 6 to 22 carbon atoms, G is a glycose residue of a sugar containing 5 or 6 carbon atoms and x is a number of 1 to 10. Only nonionic surfactants are added to the suspension to stabilize the suspension. The suspension may be stabilized by addition of the alkyl or alkenyl glycoside in combination with nonionic surfactant such as a Guebert alcohol polyethylene glycol ether or a fatty alcohol polyethylene glycol ether.

A process for making detergent granules having a bulk density above 500 g/l involving: (a) providing a fluidized bed; (b) providing an apertured inflow base located below the fluidized bed for introducing fluidization gas into the fluidized bed; (c) providing a grid interposed between the fluidized bed and the apertured inflow base, the grid having a mesh size of less than 600 &mgr;m; (d) providing a surfactant preparation in liquid to paste form; and (e) introducing the surfactant preparation into the fluidized bed to form the detergent granules.
摘要:
The aim of the invention is to improve the storage stability and flow and pumping characteristics of liquid alkylglycoside preparations by adding the minimum amounts of non-alkylglycosidic active substances, so that, owing to the increase ease with which they can be handled, the preparations can be used in the manufacture of washing and cleaning agents. This has been achieved by the use of aqueous mixtures consisting essentially of: 20 to 60% by weight of an alkylglycoside of the formula R.sup.1 --O(G).sub.n, in which R.sup.1 is an alkyl group with 8 to 22 C-atoms, G is a glycose unit and n is a number between 1 and 10; 0.1 to 3% by weight of a sulphate-type or sulphonate-type anionic surfactant selected from the group comprising alkyl sulphates, ether sulphates, alkanesulphonates, .alpha.-sulpho fatty acids, their carboxylic acid esters, sulphonation products of alkylbenzenes, alkenes or unsaturated fatty acids and mixtures thereof, the proportion by weight of alkylglycoside to sulphate and/or sulphonate being 200:1 to 20:1; plus 37 to 79.9% by weight water.

New toilet soaps contain: (a1) 4 to 7% by weight alkyl and/or alkenyl oligoglycosides and/or (a2) 2 to 7% by weight fatty acid N-allcylpolyhydroxyalkylamide; (b) 45 to 95% by weight soap and (c) 0 to 10% by weight anionic surfactants selected from the group of alkyl sulphates, isethionates, taurides, sarcosinates, mono- and dialkylsulfosuccinates, ether carboxylic acids, sulphotriglycerides and alkyloligoglucoside sulphates. These new soaps are characterized among others by an improved creaminess, a high foaming power, remarkable cosmetic compatibility with the skin and mechanical firmness.

An aqueous detergent composition containing: (a) from 12 to 15% by weight of a nonionic surfactant selected from the group consisting of alkyl oligoglycosides, alkenyl oligoglycosides, and mixtures thereof; (b) from 20 to 30% by weight of an alkyl sulfate; (c) from 40 to 60% by weight of an alkyl ether sulfate, and (d) from 12 to 15% by weight of a component selected from the group consisting of amphoteric surfactants, zwitterionic surfactants, and mixtures thereof, all weights being based on the solids content of the composition.
摘要:
In a scale with a weighing cell, which can generate weight signals representing the weight of a load each time something is weighed, and with a signal processing system which receives the weight signals and generates: weight data on the basis of the weight signals, information determined on the basis of the weight data such as purchase prices, and/or weighing data containing identification data designating the weighing operation or group of associated weighing operations in question, an elaboration is proposed, according to which the signal processing system has an encryption unit, which can generate encryption data on the basis of at least some of the weighing data, where the signal processing system can transmit a data record containing at least the portion of the weighing data used to generate the encryption data together with the encryption data.
摘要:
A process is disclosed for preparing .alpha.-branched aliphatic monocarboxylic acids with 12 to 48 carbon atoms. In a first step of the process (a), .alpha.-branched aliphatic monohydric alcohols (Guerbet alcohols) are converted in the presence of caustic alkali into the alkali salts of the corresponding .alpha.-branched aliphatic monocarboxylic acids. In a second step of the process (b), the .alpha.-branched aliphatic monocarboxylic acids are released from the alkali salts by soap splitting in the presence of an inert diluting agent.
