Abstract

A process for preparing powdery surface-active agent mixtures by spray drying aqueous suspensions of the ingredients should allow the normally used alkylbenzol-sulphonate to be replaced by alkylsulphate, without causing the spontaneous inflammation of the spray-dried goods but allowing pourable and flowable, non-clotting powdery products to be obtained. For that purpose, an amount comprised between 2 and 15 parts by weight alkylsulphate having the formula R?1-OSO3?X, in which R?1 stands for an alkyl residue with 10 to 20 C atoms and X for an ammonium ion possibly substituted by alkali, ammonium, alkyl or hydroxyalkyl, an amount comprised between 1 and 5 parts by weight alkylglycoside having the formula R?2-O(G)n?, in which R?2 stands for an alkyl residue with 8 to 22 C atoms, G stands for a glycose unit and n is a number from 1 to 10, the weight ratio between alkylsulphate and alkylglycoside being comprised between 8:1 and 1:1, and an amount comprised between 20 and 100 parts by weight of an essentially anorganic, phosphate-free excipient containing alkali carbonate and alkali alumosilicate in a weight ratio comprised between 2:1 and 1:3, are mixed with enough water to produce a flowable and pumpable mixture, which is then spray-dried using drying gasses at temperatures below 250 C until so much water is removed that a powdery, pourable product is obtained.

Description

[Detailed description of the invention] Surfactant mixture in powder form The present invention includes an alkyl sulfate, an alkyl glycode, and an inorganic carrier material. A surfactant mixture having the following characteristics, which is injectable and free-flowing in powder form, and a method for producing the same. and as formulations for producing so-called granular detergents and cleaning substances. and how to use them.

U.S. Pat. No. 4,536,319 discloses that certain alkyl polysaccharide charides, anionic co-surfactants, water-soluble salts and up to 55% by weight aluminium A granular cleaning agent containing alumosilicate is described. child According to the literature, preferred anionic surfactants are alkylbenzene sulfones. It is. When using other anionic surfactants, especially alkyl sulfates, In this case, the powder obtained by the proposed production method, i.e. spray drying, exhibits perfect flow behavior. I'm not satisfied with that.

International Patent Application No. 87102053 discloses that, based on the solid content produced, at least 0 A surfactant in which 1% by weight is an alkyl glycoside (total alkyl glycoside content is 2-60% by weight of builder (at most 2% by weight), 5-70% by weight of builder, and An aqueous slurry containing up to 40% by weight of a water-soluble filler is dried to 40-80% by weight. , describes a method for producing a granular cleaning agent. In this slurry, alkyl Glycondes are acting as viscosity reducing agents. Preferred surfactants are anionic surfactants, especially those of the alkylbenzene sulfonate type and noniodine surfactants, especially those of the etquinated fatty alcohol type.

Preferably, water present in the slurry is removed by spray drying.

The use of alkylbenzene sulfonates in detergents and cleaning substances has been criticized because this surfactant is petroleum-based. Equally good cleaning Surfactants that have detergent properties and are ecologically safer can be made from renewable raw materials, e.g. , especially sulfated products of compounds obtained from fatty alcohols. deer However, aqueous slurries containing alkylbenzene sulfonates have a spray drying odor. temperature typically employed, usually in the range of about 250°C to 350°C. Can be spray dried, but with other surfactants, especially alkyl sulfates. Aqueous slurries containing a certain amount may self-ignite.

Therefore, the problem to be solved by the present invention is that during the manufacturing process, the spray-dried product Spray-dry aqueous surfactant-containing slurries without risk of self-ignition Obtaining a powdered surfactant mixture completely free of killbenzene sulfonates The aim is to provide a method that allows The resulting product in powder form has good injectability and It is easy to flow.

The above problem is solved by the method of the present invention, which is based on the formula (1).

Spray drying removes water from the mixture to the extent that a free-flowing material in powder form is produced. A method for producing a powdered surfactant mixture essentially characterized in that . In this case, the water content in the powder generally does not exceed 20% by weight, in particular from 5% to 1% by weight. It is in the range of 5% by weight. In formulations where some of the water is bound to the carrier material as water of crystallization In this case, residual water content refers to free water that is not bound in the crystal lattice.

The method of the present invention comprises 3 to 10 parts by weight of an alkyl sulfate represented by formula (1), 2-3 parts by weight of the alkyl glyconde represented by (II) and 25-3 parts by weight of the inorganic carrier material A mixture comprising 80 parts by weight of at least 35% by weight, in particular 40-50% by weight of water It is preferable to mix water in an amount such that .

CO-builder, acrylic acid, methacrylic acid and/or Alternatively, it can be obtained by polymerizing maleic acid monomers or salts thereof. these things The quality is in the carrier material from 1% to 15% by weight, in particular from 5% to 1% by weight, based on the total carrier material. Preferably it is present in an amount of 3% by weight. Preferable alkaline in all the components mentioned above Potash metal is sodium.

Spray drying of aqueous slurries uses the type of equipment typically used for this application, This is done in a so-called spray drying tower, in which the slurry is passed through pressure nozzles at the top of the tower. When sprayed, it creates fine droplets that move to the bottom of the spray drying tower under the influence of gravity. The particles are then dried in contact with hot drying gas flowing co-currently or preferably counter-currently. Ru. The temperature of the drying gas is such that the temperature of the spray-dried particles exceeds the self-ignition temperature of the particles. It is important to place it so that it does not get too high. In the present invention, this means that The temperature of the drying gas is determined by controlling the temperature of the drying gas in the hottest part of the drying tower, the so-called ring channel. g channel), the temperature of the drying gas does not exceed the value of 250℃, Preferably in the range of 120°C to 240°C, more preferably in the range of 140°C to 210’C.
