    Abstract: The invention concerns granular washing and cleaning agents, or a component of such agents, which contain high quantities of surfactants and are manufactured by neutralizing a preparation containing the surfactants in their acid form and subsequent granulation with additional solid materials. Such agents frequently have a poor colour value if the anionic surfactants are pre-bleached in their acid form. Agents with a good colour value are obtained, however, if an acid surfactant preparation containing one or more anionic surfactants in their acid form is (a) neutralized with a stoichiometric amount, or an excess of, a neutralizing agent in an intimate-mixing device, and at the same time as the neutralization, bleached by the addition of a peroxide bleach and (b) granulated together with additional solid materials to obtain a dust-free product and, optionally, simultaneously or subsequently dried.

    Abstract: 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 increased 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 wt. of an alkylglycoside of the formula R1-O(G)n, in which R1 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 wt. of a sulphate-type or sulphonate-type anionic surfactant selected from the group comprising alkyl sulphates, ether sulphates, alkanesulphonates, α-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 wt. of water.

    Abstract: The invention relates to new anhydric surfactant mixtures containing a) fatty alkyl sulphates with 16 and/or 18 carbon atoms and b) alcohol sulphates with 12 to 15 carbon atoms in a weight ration of 70:30 to 90:10. The mixtures are characterized in that they have excellent detergent properties while having a synergistically reduced irritant potential as well as good dissolving capacity and very good flowability.

    Abstract: The invention concerns a method of manufacturing powder-form anionic-surfactant preparations by spray-drying aqueous suspensions of the components. The aim of the invention is to be able to replace the usually used alkylbenzene sulphonate by an alkyl sulphate, without the spray-dried material spontaneously igniting, but nevertheless give powders which are pourable and free-running and do not form lumps. This is achieved by mixing 90 to 180 parts by wt. of an alkyl sulphate of the formula: R1-OSO3X, in which R1 is an alkyl group with 10 to 20 C-atoms and X is an alkali-metal ion, an ammonium ion or an alkyl-substituted or hydroxyalkyl-substituted ammonium ion, and 120 to 300 parts by wt. of a substantially inorganic phosphate-free carrier material containing an alkali-metal aluminosilicate and an alkali-metal silicate in the ratio from 100:1 to 20:1 or from 5:1 to 1:2, with sufficient water to form a free-flowing, pumpable mixture. Enough water is then removed from this mixture by spray-drying, using drying gases, at temperatures below 250 °C, that a free-flowing powder is produced.
