Description

Procedure to produce components or granular detergent compositions.

The present invention relates to a process for the continuous preparation of a composition or component granulated detergent having a high bulk density and Good flow properties. In such compositions and components the use of crystalline zeolite A is known, which is a material water insoluble lens well known in the art of detergents as a detergency builder especially suitable for removing cations, such as calcium and Magnesium, from hard water.

The crystalline zeolite A is a finely powdered divided. It has been a common practice to process the powder finely divided into larger granules (typically 400 to 1000 micrometers) before incorporation into finished products, especially finished detergent compositions. They know each other various granulation processes that include drying by Spray and agglomeration. The agglomeration processes conventional in which zeolite A is used as one of the components have long been known in the state of the technique:

Document GB2005715, published on April 25 from 1979, describes an agglomeration process based on zeolite A. The zeolite A is agglomerated together with carbonate / bicarbonate to produce agglomerates of non-ionic surfactant.

The patent US-A-5 468 516 describes a process of producing nonionic detergent granules having a high apparent density, excellent fluidity properties of dust and lack of coking, where, among others, process from 20 to 95 parts by weight of a reinforcing additive of the detergency, from 1 to 20 parts by weight of an absorbent vehicle of porous oil and 10 to 60 parts by weight of a non-surfactant ionic.

WO93 / 25378, published on 23 December 1993, describes a process for the manufacture of granulated detergents comprising zeolite A. Zeolite A is agglomerated with a very active neutralized surfactant paste in a high speed mixer and in a mixer / agglomerator of moderate speed to manufacture surfactant agglomerates anionic

One of the limiting factors of the activity of the aforementioned prior art surfactant is the ability of zeolite A to absorb organic materials liquids It has been suggested that the replacement of zeolite A by Zeolita P (specifically the Zeolita MAP) could solve this trouble:

In EP521635, published on January 7, 1993, it describe granulated detergents prepared using 10% to 100% of Zeolita MAP. Zeolite MAP has a chemical composition different from that of zeolite A. In Example 1 of this application for patent notes that the oil absorption capacity of the Zeolite MAP is 41.6 ml / 100 g and that this is higher than that of measured samples of zeolite A, in which it is 26 to 35.5 ml / 100 g.

However, the modification of the structure Conventional crystalline zeolite A chemistry (i.e. modifying the stoichiometric ratios of Si, Al, Na, O, H) no It is always desirable since this involves the alteration of others Properties and characteristics of Zeolite.

The object of the invention is to provide a granulation process for the manufacture of granulated detergents which incorporate very absorbent crystalline Zeolite in agglomerates granules, without losing any of the properties of the additive detergency builder, especially the ability to calcium exchange and calcium exchange rate.

According to the invention, this object is achieved using a modified crystalline zeolite A that has a higher oil absorption capacity in a process as specified in claim 1. Zeolite A has physical properties modified (i.e. crystallinity, surface, humidity level, etc.) more than a modified chemical structure in order to achieve an oil absorption capacity of at least 40 ml / 100 g. In this way you can continue to use the excellent strengthening properties of the detergency of zeolite A.

It is another object of the present invention provide a granulation process for the manufacture of granulated detergents that have improved processability and a smaller amount of oversized particles (or "lumps") formed in the process.
