Description:
Builder component Technical field The invention relates to builder components which have an excellent building performance an improved dispensing and dissolution and which are in particular useful for detergent compositions.

Background to the Invention In the past decades detergent manufacturers have been focused on the development of improved builders as alternatives to phosphate builders. On one hand, new builder materials have been developed and on the other hand existing builders or builder combinations have been improved, for example by optimizing the levels or ratios of the builder materials. In general, most detergents still employ polycarboxylate builders and silicate builders, such as aluminosilicates, amorphous and crystalline sodium silicates.

It has been found that one of the main complaints of the users of detergent products is that the products do not always dispense satisfactory. This results in residues of the product in the dispensing drawer, for example in the form of a gel, in the washing machine and also on the fabrics after the wash. This can be in particular a problem with certain ingredients or with high density products, under cold water washing conditions or when limited amounts of water are used in the washing process, such as the case in the initial phase of the washing process when small amounts of water contact the product in the dispensing drawer or in the interior of the machine.

A problem related to the gelling of the product is that the product is not delivered efficiently to the wash because not only the gelling ingredients do not dispense well, also the product trapped in the gel is not dispensed well, whereby these ingredients can not contribute to the cleaning performance. Furthermore, the incorporation in detergents of certain ingredients which have a tendency to gel or cake have a negative impact on the flowability of the product.

Another problem associated with certain detergent ingredients is that they do not always dissolve satisfactory, for example aluminosilicates, amorphous silicates, coarse silicate materials. This may result in a reduced cleaning performance or deposition of product on the fabric or the washing machine.

The inventors have now found that often those ingredients which dispense well, do not dissolve satisfactory and have a tendency to deposit and form residues on the fabrics in the wash. On the other hand, ingredients which dissolve well, have a tendency to gel upon initial contact with water.

The inventors have now found that a builder component, containing a ground crystalline layered silicate material whereof the particles have a particle size of less than about 100 microns and having a weight average particle size of more than about 15 microns dissolves readily and provides excellent building. Preferably, the builder component is also such that 90% by weight of the particle has a particle size of from 17.3 to 88. 2.

They have found that detergent compositions comprising this builder component have an improved flowability, an improved dispensing, a reduced gelling and a less product residues in the dispensing device, in the washing machine and on the fabrics, compared to other silicate materials, such as materials of larger particle size, smaller particle size, aluminosilicates, amorphous materials, or non-layered materials. It is believed that that the layered structure is essential to reduce the formation of gels, whilst the particle size is essential to provide a product which both dispenses and dissolves whilst having a good flowability. Furthermore, it is believed that the ground material has a modified surface structure whereby improved building and dispensing are achieved.

Furthermore, it has been found that the intimately mixing this crystalline layered silicate material with other detergent ingredients which have a tendency to form residues or gel, such as surfactants, in particularly anionic surfactant, reduces the formation of residues or the gelling of the ingredients and thus improves the dispensing and the efficiency cleaning performance of ingredients.

Summarv of the Invention The invention provides a builder component comprising a ground crystalline layered silicate which comprises at least 95% or even 98% or even 100% by weight crystalline layered silicate having a particle size of less than 150 microns or even 102 microns, whilst having a weight average particle size of more than 15.0 microns, preferably from 16.0 to 48.8 microns.

The builder component is in particular useful in solid detergent compositions, in particular solid laundry and dish washing detergent compositions.

The invention also relates to the use of a builder system comprising a ground crystalline layered silicate which comprises at least 95% or even 98% or even 100% by weight of crystalline layered silicate having a particle size of less than 150 microns or even 102 microns, whilst having a weight average particle size of more than 15.0 microns, preferably from 16.0 to 48.8 microns, in a detergent composition, comprising a surfactant and other detergent components, for improving the dispensing of the detergent component.

Such materials are available as METOLOSE SM 100 and METOLOSE SM200, which are the trade names of methyl cellulose ethers manufactured by Shin-etsu Kagaku Kogyo KK Additional classes of SRA's include: (I) nonionic terephthalates using diisocyanate coupling agents to link polymeric ester structures, see U.

The compositions herein can take a variety of physical forms including liquid, but preferably solid forms such as tablet, flake, pastille and bar, and preferably granular or tablet forms.

The compositions in accord with the present invention can also be used in or in combination with bleach additive compositions, for example comprising chlorine bleach.

Detergent compositions herein, in particular laundry detergents, preferably have a bulk density of from 280 g/litre to 200 g/litre, or preferably from 300 g/litre or even 350g/litre or 420g/litre to 2000g/litre or more preferably to 1500g/litre or 100 g/litre or even to 700g/litre.

Laundry Washing Method Machine laundry methods herein typically comprise treating soiled laundry with an aqueous wash solution in a washing machine having dissolved or dispensed therein an effective amount of a machine laundry detergent composition in accord with the invention. By an effective amount of the detergent composition it is meant from 1 Og to 300g of product dissolved or dispersed in a wash solution of volume from 5 to 65 litres, as are typical product dosages and wash solution volumes commonly employed in conventional machine laundry methods.

The composition may also be formulated such that it is suitable for hard-surface cleaning or hand washing or for pre-treatment or soaking of soiled and stained fabrics.
