Abstract

Use of 0.1-10 wt.% of at least trihydric alcohol and their reaction products with ethylene oxide (EO) and/or propylene oxide (PO) as additive to increase the rate of dissolution of particulate laundry detergent formulations in water.

Description

The invention relates to the use of at least trivalent Alcohols and their reaction products with ethylene oxide and / or Propylene oxide as an additive to particulate detergent formu lations to increase their rate of dissolution in water Amounts of 0.1 to 5 wt .-%, based on the detergent form lations.

Particulate detergents should be possible when they are added to water disintegrate as quickly as possible into the finished parts To form wash liquor. The dissolving speed of some particles shaped detergent formulations, especially compact detergents that, for example, have a bulk density of at least 550 g / l, but when brought together with water is still in need of improvement.

The invention has for its object a detergent additive to provide that to an increase in resolution speed of particulate detergents in water.

The object is achieved according to the invention by using min at least trihydric alcohols or their reaction products Ethylene oxide and / or propylene oxide as an additive to particulate Detergent formulations to increase their dissolving speed in water in amounts of 0.1 to 10 wt .-%, based on the washing medium formulations.

For example, suitable as at least trihydric alcohols Glycerin, diglycerin, triglycerin, tetraglycerin, pentaglycerin, Hexaglycerin, heptaglycerin and octaglycerin, pentaerythritol, tri methylolpropane, erythritol, mannitol, sorbitol, sucrose, glucose and Polyvinyl alcohols with molecular weights up to 20,000. Instead of one Individual compounds can also be mixtures of the above Use connections. Is of particular technical interest for example the use of hydrogenated starch hydrolyzates or hydrogenated glucose syrups. For example, you can in the trade available hydrogenated starch hydrolysates from Cerestar put under the trademark SORBIDEX 200 and SORBIDEX 122 Tobe offered.  

Particularly effective products for increasing the dissolving speed Particulate detergent formulations are Um settlement products of at least trihydric alcohols Ethylene oxide and / or propylene oxide. These implementation products and Processes for their production belong to the state of the art. So is obtained, for example, by reacting glycerol, erythritol, Pentaerythritol, trimethylolpropane, mannitol or sorbitol with ethylene oxide and / or propylene oxide in the presence of the usual alkoxylie tion catalysts such as KOH, NaOH, alkali alcoholates such as sodium methylate, Ca hydroxide, Ca oxide or supported catalysts wash medium additives that increase the dissolution rate of detergent formu in water compared to polyethylene glycol heights. The alkoxylated products can be wide or too have a narrow molecular weight distribution. Really important are the reaction products of glycerol, erythritol, Pentaerythritol, trimethylolpropane, mannitol or sorbitol with ethyl noxide.

For example, 1 mol of at least trivalent Al is used alcohol with 1 to 100 moles of ethylene oxide. These products can can be modified by adding 1 to 35, preferably 1 to 20 and particularly preferably 1 to 15 mol Can continue to react propylene oxide. When making modes However, it is possible to add the adducted products of ethylene oxide also proceed in such a way that a mixed gas of ethylene oxide and Apply propylene oxide to the at least trihydric alcohols leaves. Another possible variation is given by the fact that the alcohols mentioned first with propylene oxide and finally reacted with ethylene oxide. The implementation products from 1 mole of at least 3-valent alcohol with 1 to 100 moles Ethylene oxide and 1 to 35 moles of propylene oxide can also be produced from blocks from ethylene oxide / propylene oxide / ethylene oxide units or from Blocks of propylene oxide / ethylene oxide / propylene oxide units be constructed. Within the limits for Ethylene oxide and propylene oxide can be the reaction products any block length and any sequence of blocks point. So you can, for example, at least 1 mole 3-valent alcohol successively 3 to 9 moles of ethylene oxide, 3 to Add 6 moles of propylene oxide and 3 to 9 moles of ethylene oxide. To this Reaction products can optionally further ethylene oxide and / or Propylene oxide units or blocks can be attached. Other suitable reaction products contain z. B. Blocks of 5 up to 10 ethylene oxide units, 5 to 30 propylene oxide units and optionally an additional block of 50 to 80 ethyleneo xid units. Reaction products from are particularly preferred 1 mol of trimethylolpropane used with 1 to 100 mol of ethylene oxide,  mostly reaction products of 1 mol of trimethylolpropane with 3 to 30 moles of ethylene oxide.

Ethoxylated hydrogenated sugars such as sorbitol are also suitable or mannitol and ethoxylated polyvinyl alcohol as detergent additive, which increases the dissolving rate of detergent formu Lulations increased when dissolved in water. According to the invention additives used in amounts of 0.1 to 10, preferably 0.5 to 5 and in particular from 0.5 to 2.5% by weight in the wash medium formulation included. You will prefer using the other detergent ingredients mixed as homogeneously as possible. Man however, it can also be applied to the surface of the fine-particle wash Apply agent formulations and allow to diffuse in.

The average particle diameter of the particulate wash medium formulations is, for example, 200 µm to 5 mm and is preferably in the range of 1 to 3 mm. You can do that However, portion detergent formulations so that for a wash in a washing machine just a ball or a Tablet is required. Have such bullets or tablets then a much larger average particle diameter than mentioned above. The advantage of such a relatively large volume part Chen lies in the simple dosage. When using the alkoxylated to be used according to the invention, at least Trihydric alcohols in the commercial detergent Persil® Megaperls occurs in addition to the described increase in Release speed a considerable increase in dirt release send effect (soil release effect) of the detergent.
