Description

COMPOSITIONS OR DETERGENT COMPONENTS TECHNICAL FIELD The present invention relates to detergent compositions or components comprising certain hydrophobically modified cellulosic materials, which provide fabric protection, a particle size and preferably a specific particle size distribution.

BACKGROUND OF THE INVENTION It is generally known that fabrics and textile products tend to wear out over time due to mechanical action during washing and also during use. For example, short fibers are dislodged from the fabric and can form lint, lint or "beads" that are visible on the surface of the fabrics and diminish the novelty appearance of the fabric. The co-pending application PCT / US98 / 19139 discloses the use of hydrophobically modified cellulosic polymers found to provide excellent integrity benefits to fabrics. Without wishing to be bound by theory, it is believed that these materials associate themselves with the fibers of fabrics and textiles during washing, and thereby reduce or decrease the tendency of washed fabrics / textiles to deteriorate in appearance.

These materials are not easily soluble in water and therefore the release in washing and fabrics depends largely on the dispersion of the material in the wash water. The inventors have found that under certain conditions, these hydrophobically modified cellulosic polymers do not always disperse satisfactorily, producing a reduced action and also localized residues of the material on the fabrics. In addition, the inventors also found that under certain conditions other detergent ingredients can become trapped in the material! cellulose, causing additional waste problems, or even reduced action of these other ingredients. The inventors have now found that when the hydrophobically modified cellulosic material of a specific particle size is used, these problems can be reduced or even avoided. They found that when the selected material, which preferably has a particle size of less than 1000 microns, or even less than 710 microns, or even less than 500 microns, a better dispersion of the material is obtained, and also a better dispersion or dissolution of the material. Other detergent ingredients that are in close contact with the polymers. They also found that an improved efficiency of the hydrophobically modified cellulose material is obtained, and therefore improves the integrity of the fabric. They also found that it may be preferable that the material has a reduced particle size distribution.

The co-pending application US 60/113306 discloses that these hydrophobically modified materials can be formed into agglomerates, for example with builders such as zeolite, and then incorporated into detergent compositions. The inventors have now found that when hydrophobically modified cellulose polymers of selected particle size are incorporated in these preformed particles, such as agglomerates, but also in spray-dried blown powders, a better dispersion or dissolution of the preformed particles is also achieved, and also of the ingredient and importantly of the cellulose material itself.
