Bulky and free-flowing, powdery surfactant mixture

The invention relates to a slippable and free-flowing, powdery concentrated surfactant mixture as well as elite detergents or cleaning agents made from it.

In detergents and cleaning agents, sulfated and sulfonated washing active substances are mainly used of the alkylbenzene sulfonate, fatty alcohol sulfate, alkyl ether sulfate, alkyl sulfonate and - of different constitution - protein condensation products. Of these, the petroleum alcohol sulfates are known to be easily dryable. Those contained in the mass are already sufficient to dry them. Production of small amounts of electrolytes. Also no significant difficulties in drying prepare the aulfonate only slightly sticky and alkyl benzene sulfonates. To dry them , it is known to add large amounts of water-binding electrolytes. To further improve the flowability of alkylbenaolsulfonates, the addition of disodium salts of 06- sulfofatty acids to substances containing water-binding electrolytes is known. It is also ready for the purpose of drying detergent enhancers

the addition of sulfosuccinic acid derivatives in an amount between $ 10 and $ 40> to the known easily dryable alkylbenzenesulfonates alone or in a mixture with alkyl sulfates and / or alkyl sulfonates as a cleaning booster for dry cleaning has become known.

According to the prevailing teaching, the washing active substances of the alkyl ether sulfate (petroleum ether sulfate), alkyl phenol ether sulfate and protein condensation products are considered to be absolutely undryable. It is true that attempts have already been made (patent specification 1 187 758) to use capillary active substances in which the hydrophobic hydrocarbon radical and the water-solubilizing sulfate or sulfonate group are connected to one another via oxygen, nitrogen and sulfur or via a residue containing oxygen, nitrogen or sulfur Ways of adding large amounts of water-binding electrolyte in connection with disodium salts of OÖ -Sulf of ettsäuren to dry. However, the drying in this way requires a high proportion of up to 80 water-binding i "electrolytes, such as sodium sulphate, which is considered both for transportation and for the further processing of the washing-active substance as Baiast. In this way, the desired drying of the substance in its concentrated form is not possible.

The present invention aims to provide a concentrated, free-flowing surfactant mixture containing the substances or protein condensation products mentioned or a free-flowing detergent and cleaning agent made from it. The invention consists in that the surfactant mixture is one or more sulfosuccinic acid derivatives of fatty acid alkylolamides and / or primary or secondary fatty alcohols of the structures

The invention surprisingly results in complete drying of the substances previously considered to be non-dryable also made possible in high concentrations. As an

games for substances whose drying on the inventive The fatty acid esters or fatty alcohol ethers of oxethane sulf «acid, which can be achieved with success Oxypropanesulfonic acid, dioxypropanesulfonic acid or others Oxysulfonic acids, with the corresponding derivatives of dioxypropane sulfonic acid also called "alkyl glyceryl ether sulfonate" or referred to as "fatty acid glycerol ester sulfonates" as well as fatty acid amides derived from aminosulfonic acids, in particular aminoethanesulfonic acid to name. These also include compounds of the sulfate type, such as the sulfated fatty acid alkylolamides, just like the sulfated partial esters of fatty acids or partial ethers of fatty alcohols with polyvalent ones Alcohols, such as with glycol, diglycol, triglycol and higher glycols or with glycerine, di- and Polyglycerines, as they are produced by the addition of ethylene and / or propylene oxide and / or glycide can be obtained on fatty alcohols or fatty acids. Finally there are the addition products the alkylene oxide compounds mentioned to other suitable starting materials, such as to alkylphenols, alkyl! thiophenols, fatty acid amides or Fatty acid alkylamides, fatty amines, mercaptans, in their sulfated form and protein condensation products to call. In this case, such a complete drying can be achieved that even that was previously excluded

respected use of fatty alcohol ether sulfates in powdered Cleaning agents in high proportions is made possible. However, a concentrate according to the invention can also without difficulty on any other dry, free-flowing, lumpy, pasty or liquid washing or Cleaning agents are processed. For this purpose, any other anionic, ampholytic or nonionic surfactants are added, as well as any other aggregate, for example builder, Dirt carrier, optical brightener or the like.

The surfactant mixture according to the invention is trickling rock and is in the form of its concentrate - apart of course from minor production-related impurities - 100 56 washing-active substance. This results in a further essential advantage that with the often necessary transport of the surfactants, the previously necessary costly transport of unnecessary or even disruptive auxiliaries - in particular larger amounts of water or drying substances - is dispensed with.

Some examples which illustrate the invention are given below:

example 1 An aqueous solution consisting of 89.5 parts by weight

109812/1648

Alkyl triglycol ether sodium salt, 28 jlig (alkyl chain C 10 to C 14) and 187.5 parts by weight of the sodium salt of a. Fatty alcohol sulfosuccinic acid hardester 40% (fatty alcohol base C 12 to C 14) are sprayed onto a drum dryer or optionally in a hot air spray tower at an inlet temperature of 200 - 250 ° C and an outlet temperature of approx. 100 ° C at 3-5 atm dried. The result is a white, powdery, pourable and free-flowing surfactant mixture with a WAS content of approx. 98 #, which consists of 25 Ί »alkyl triglycol ether sodium sulfate and 75 S ^ of the sodium salt of a fatty alcohol sulfosuccinic acid half ester.

The surfactant mixture can be further processed:

a) by adding builders, etc. to a powdery mild detergent or rough detergents of all kinds;

b) by adding water, solubilizers, hydrotropes etc. to liquid detergents, mild detergents or dishwashing detergents.

of lauric acid monoethanolamide sulfosuccinic acid half-ester (based on solids) removed the water. The resulting dry surfactant mixture has a WAS content of over 98 # on.

The surfactant mixture obtained in this way can be used, inter alia, for the production of surfactant bars or soap-surfactant bars, furthermore as Washing active substance can be used for hand washing pastes, hand washing powders or hand washing creams. It can also be used as a Surfactant base, possibly in combination with other anionic, nonionic and ampholytic surfactants for production of powdery, pasty, gel-like and liquid bath preparations and hair shampoos can be used.
