Compositions containing secondary paraffin sulphonate and

tetrahydroxypropylethylene

The invention relates to aqueous compositions containing 45-65% by weight of secondary paraffin sulphonate, 1-10% by weight

Tetrahydroxypropylethylenediamine and water. Secondary paraffin sulfonates have long been known as base surfactants, especially for detergent applications, dishwashing detergents and industrial cleaners.

Secondary paraffin sulfonates are surfactants which, statistically distributed, predominantly contain an SO ₃ X group in the secondary position on the paraffin hydrocarbon chain and to a lesser extent two or more SO ₈ X groups in the secondary position on the paraffin hydrocarbon chain. The paraffin hydrocarbon chains are predominantly linear and only a minor proportion of 5% by weight or less branched paraffin chains having 8 to 22 carbon atoms. The group X can stand for Li ⁺ , Na ⁺ , K \ Mg ⁺⁺ , Ca ⁺⁺ , Al ⁺⁺⁺ , NH ₄ ⁺ and quaternary ammonium ions [HNR ¹ R ² R ³ ] ⁺ , where R ¹ , R ² and R ^{3 is} independently hydrogen, a linear or branched alkyl group having 1 to 22 carbon atoms, a linear or branched, mono- or polyunsaturated alkenyl group having 2 to

22 carbon atoms, a linear mono-hydroxyalkyl group with 2 bis

10 carbon atoms, preferably a mono-hydroxyethyl or mono-hydroxypropyl group, as well as a linear or branched di-hydroxyalkyl group having 3 to 10 carbon atoms, may be.

This class of surfactants can be obtained by sulfoxidation of paraffins

Photochemical conditions are produced and is, for example, in the market under the trade name Hostapur ^® SAS in the concentrations

30 wt .-%, 60 wt .-% and 93 wt .-% available. About 60% by weight aqueous secondary paraffin sulfonate is pasty and tends to phase separate. To prevent the separation, it must be constantly stirred or circulated in a circle. Therefore, additives are sought which suppress a phase separation and thereby the

energy-intensive stirring or pumping process to avoid phase separation.

It is known that when added from 5 to 10 wt .-% of ethanol or i-propanol to about 60 wt .-% aqueous, secondary Paraffinsulfonat the

Phase separation is omitted. The disadvantage, however, is that the preparation is flammable and appropriate protective measures must be taken.

Object of the present invention was therefore to provide compositions with a high proportion of secondary Paraffinsulfonat, even with longer storage times and greater temperature fluctuations no

Phase separation and contain no combustible components.

It has surprisingly been found that this object is achieved by

method of preparation:

Hostapur ^® SAS 60 is introduced and tetrahydroxypropylethylenediamine added with stirring at room temperature and stirred for 5 minutes.

Hostapur ^® SAS 60 is a composition of

secondary sodium paraffin sulfonate (about 60% by weight) in water. The secondary paraffin sulfonate used contains about 97% by weight of paraffin sulfonates having 14 to 17 carbon atoms. The n-paraffin content of the secondary paraffin sulfonate is> 98% by weight. The secondary paraffin sulfonate is 100% saturated. It consists of about 90 wt .-% of monosulfonated and about 10 wt .-% of disulfonated and higher sulfonated Paraffinsulfonaten. The phase stability of compositions 1-5 and V-6 was assessed after the compositions over a period of 6 months

alternately stored at a temperature of 40 ° C for 12 hours and at a temperature of 5 ° C for 12 hours. One watched

However, phase separation does not mean that it will take 6 months to complete

occured.

From the results of Table A it can be seen that Examples 1 to 5 according to the invention represent phase-stable compositions. In contrast, phase separation occurred in the composition of Comparative Example V-6 with a small amount of tetrahydroxypropylethylenediamine.

The viscosity of the Hostapur ^® SAS 60 is in the compositions of the invention by addition of tetrahydroxypropylethylenediamine

Examples 1 - 5 lowered. These compositions have such

Viscosities on that they can deal with commercial pumps without difficulty promote. When tetrahydroxypropylethylenediamine is added in amounts greater than 10% by weight, the viscosities of the compositions increase significantly so that they become more viscous. This showed z. B. to a comparative composition that has been prepared from 89.0 wt .-% Hostapur ^® SAS 60 and 11 0 wt .-% tetrahydroxypropylethylenediamine. Such compositions are much more difficult than the

promote compositions according to the invention by means of pumps.
