A process for the production of a particle composition containing, at least one resin and at least one pigment is described, said process comprising the following steps: *extrusion of a mixture containing said at least one resin and said at least one pigment without induced heating; *subsequent extrusion, with induced heating, of the mixture obtained from the preceding extrusion; *granulation of the mixture thus obtained. With the abovementioned process it is possible to obtain a composition having granules with an average diameter less than 2 microns and a greater homogeneity than the known processes.

This invention relates to non-bleeding, non-staining occult particles for use in granular or powdered laundry care compositions such as laundry detergents, laundry aids, and fabric care compositions. The occult particles are comprised of a clay carrier and a coloring agent and are characterized as being substantially indiscernible when contained in the laundry care composition.

A solid colorant including a. 30-97 wt % of a pigment, b. less than 5 wt % of a solvent c. 3-40 wt % surfactants and wherein: the ratio S/A [Std dev of the particle size distribution/average particle size] of the solid colorant is <25%, preferably <22% and more preferably <20%, wherein wt % is relative to the total weight of the solid colorant, and wherein the particle size distribution is determined with light scattering with fully automated image analysis according to ISO 13322-1 Static image analysis First edition 2004 Dec. 1 by the use of the OCCHIO ZEPHYR ESR analyzer. A process for making the solid colorant, and the use of the solid colorant for tinting base paints by volumetric dosing of the solid colorant to the base paint.

A method to produce a dye, which is suited to be applied on fabrics, starts from textile waste material. The method includes an initial step, during which textile waste material is provided, which includes textile fibers, which were previously dyed. In a pulverization step, the textile fibers are pulverized to obtain the dye.

The present invention relates to dry particulate encapsulation compositions comprising a water-insoluble matrix comprising at least 70% by weight of proteins, based on the total weight of the matrix and a moisture content of about 5 to 10% by weight, based on the total weight of the matrix and an encapsulate encapsulated in the matrix, wherein the matrix once wetted in a clear colorless aqueous solution or in mineral oil has a lightness value (L*) greater than about 40, a color vividness or Chroma (C*) lower than about 33 and a hue angle between about 70 and 90. The encapsulation compositions of the present invention are useful in encapsulating dyes, medications and vitamins. Fine particulate encapsulation compositions comprising natural dyes can be used in lieu of artificial lakes in confectionery, cosmetics and caplets color coatings.

The present invention relates to a laundry detergent composition comprising a particle comprising hueing agent and clay. The particle can be incorporated into laundry detergent products, such as a laundry detergent powder. The particle exhibits an excellent storage stability profile with very little bleeding of the hueing dye from the particle, exhibits excellent fabric deposition of the hueing dye during a laundering process without causing any spot staining of the fabric, and does not impact the visual appearance of a laundry detergent powder when incorporated therein.
