Use of secondary paraffin sulfonates to increase the

Cleaning power of enzymes

The invention relates to the use of secondary paraffin sulfonates for increasing the detergency of enzymes.

The use of enzymes in detergents and cleaners and

especially in laundry detergents for textiles, for example against oil and fat-containing, protein-containing or starch-containing soils, is already known.

However, there remains a need to further improve the detergency of enzymes.

It has surprisingly been found that the detergency of enzymes can be significantly increased by the addition of secondary paraffin sulfonates having 8 to 22 carbon atoms.

The present invention therefore relates to the use of one or more secondary Paraffinsulfonate having 8 to 22 carbon atoms to

Increasing the cleaning power of one or more enzymes. The use according to the invention brings, for example, the advantage that the cleaning power of corresponding agents containing secondary

Paraffinsulfonate and enzymes, especially detergents against stains on textiles, is increased. Alternatively, also at

comparable cleaning performance, the amount of detergent can be lowered, which offers ecological benefits. In addition, it can be cleaned at low temperatures, which can reduce energy consumption. Secondary paraffin sulfonates have long been known as base surfactants, especially for detergent applications, dishwashing detergents and industrial cleaners.

It is also known, for example, from Clariant brochure of May 2000 "A traditional specialty cleaners for innovative" with respect Hostapur ^® SAS, a secondary paraffin that both enzymes as well as secondary

Paraffin sulfonate in common, e.g. can be used in liquid detergents. It is also known from this Clariant brochure that

secondary paraffin sulfonates such as Hostapur ^® SAS enzymes such. B. proteases or lipases can stabilize and in formulations such. B. in liquid

Detergents better enzyme compatibilities than most anionic surfactants such. As linear alkylbenzenesulfonates (LAS) or alkyl sulfates. It is also disclosed there that in liquid detergents, based on so-called "heavy duty" and "light duty" Liquid Detergents the amount of enzyme can be reduced by the use of Hostapur ^® SAS.

The secondary paraffin sulfonates may be prepared by sulfoxidation of paraffins under photochemical conditions and are, for example on the market under the trade name Hostapur ^® SAS in the concentrations

In the context of the present invention, "secondary paraffin sulfonate" means that the sulfonate groups are attached to the non-terminal paraffin moiety.

Preparation of Formulations A, B, I and II:

I Add components B to A with stirring at room temperature. II Successive addition of components C to I with stirring.

III Successive addition of components D to II with stirring. 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 washing tests were carried out under the following conditions:

Washing machine: Siemens S 16-79

Program: Standard / Color

Load: 3 kg

Temperature: 20 ° C

Spin: 1400 revolutions / minute

Water quantity: 12 liters

The differences of the remission values AR 457 nm from washed to unwashed textiles were measured. The measured soiled textiles are available for purchase. The following textiles / soils were measured: WFK 20 PF pigment / vegetable fat, WFK 10 N whole egg / pigment, CS 6 salad dressing with natu r black, CS 73 carob gum / pigment, CS 10 butterfat stained, CS 27 potato starch stained, CS 28 rice starch stained, CS 8 grass, PC 3 chocolate / milk / soot, C 3 chocolate / milk / soot, CS 1 blood aged, C 5 blood / milk ink, EMPA 162 starch, EMPA 164 grass, EMPA 112 cocoa, EMPA 117 blood / milk / Indian ink and EMPA 116 blood / milk / ink.

Measurement:

Device: Elrepho 3000 (Datacolor)

Aperture: XLAV 0 34mm

Edge filter: 400 nm The measurements were made directly after preparation of the formulations.

In the following Table A the totals of the measured differences of the remission values AR 457 nm are listed over all 17 mentioned textiles / stains.

Table A Sum over the measured AR 457 nm

The formulations A ^' and B ^' without enzyme can be prepared like the formulations A, B, I and II, but the preparation is then terminated after step II. It can be seen from the results of Table A that formulation A with enzyme and with secondary paraffin sulfonate gives a significantly better washing result than the analogous formulation B with enzyme and linear

Allyl benzene sulfonate, although with the corresponding formulations A ^' and B ^' without enzyme, the formulation B ^' with alkyl benzene sulfonate a better

Washing result provides as the formulation A 'with secondary paraffin sulfonate.
