Definitions

  • the present invention relates to a fast-dissolving, low- staining granular composition containing a visually distinct, eg coloured or fluorescent, ingredient, for example, a photobleach.
  • the invention more particularly relates to granules containing a coloured or fluorescent ingredient which may be incorporated into a detergent composition without encountering the problem of staining of the fabric during the wash.
  • Coloured speckles are used in detergent formulations to give a distinct appearance to the product as well as to deliver functional benefits. In the wash process, it is undesirable that these coloured speckles settle on to the fabric surface leading to staining of the fabric. It has also been noticed that these stains do not get washed out in subsequent laundering. Further the uneven concentration of these speckles on the substrate could result in localised higher levels of the active causing fabric damage.
  • US 4 097 418 discloses a granular coloured speckle having non-staining qualities comprising an agglomerate of a granular water soluble inorganic alkaline salt with an anionic surfactant which contains a dye or pigment. Mixing of the dye and the anionic surfactant prior to agglomeration prevents the pigment particles from attaching to each other and on to the fabric surface thus preventing staining of the fabric.
  • US 4 762 636 (Ciba-Geigy, 1988) discloses a process for obtaining granules with defined physical properties that float on an aqueous treatment liquor and release the active ingredient without getting deposited on to the substrate.
  • the present invention provides a granular composition suitable for incorporation into a particulate detergent composition, the granular composition comprising
  • the water-soluble or water-dispersible barrier material serves to provide a protective layer or coating on the combination of the coloured or fluorescent ingredient and its carrier material, the ⁇ -hydroxy organic acid.
  • Preferably at least a part of the inorganic flow modifier is also thus protected. Additional inorganic flow modifier that is not protected by the barrier material may also be present .
  • the coloured or fluorescent ingredient is dispersed onto, or in the form of a coating over, the ⁇ -hydroxy organic acid
  • the barrier material is in the form of a coating over the said mixture of ⁇ -hydroxy organic acid and flow modifier, being combined with (in admixture with) any remaining portion of the flow modifier.
  • the granule composition comprises:
  • the granular composition of the invention may be prepared by a process in which the coloured or fluorescent ingredient is dispersed onto the ⁇ -hydroxyacid, which is then mixed with part or all of the inorganic flow modifier and the whole treated with the barrier material, then granulated with any remaining inorganic flow modifier.
  • a process for the preparation of a granule composition which comprises the steps of: (i) dispersing the coloured or fluorescent ingredient on the ⁇ -hydroxy acid and granulating with the inorganic flow modifier or a portion thereof;
  • the ⁇ -hydroxy organic acid may be selected from citric acid, adipic acid, tartaric acid, maleic acid and others.
  • An especially preferred acid is citric acid.
  • coloured or fluorescent ingredients are photoactivators (also known as photobleaches) , especially phthalocyanines; coloured dyes and pigments; fluorescent whitening agents; and mixtures thereof.
  • photoactivators also known as photobleaches
  • phthalocyanines especially phthalocyanines
  • coloured dyes and pigments especially coloured dyes and pigments
  • fluorescent whitening agents especially preferred ingredients are the photobleaches, zinc and aluminium phthalocyanine sulphonates .
  • the inorganic flow modifier can be selected from china clay, (preferably washed china clay) , silica, precipitated silica, precipitated calcium carbonate and diatomaceous/siliceous earth. China clay, silica and mixtures thereof are especially preferred.
  • the water-soluble or water-dispersible, preferably water- soluble, barrier material may suitably be selected from water-soluble starches, polyvinyl alcohols, polyethylene glycols and latex. Preferred materials are starches and polyvinyl alcohols.
  • the granules of the present invention may be prepared by dispersing the coloured or fluorescent ingredient on the ⁇ -hydroxy organic acid, for example, in a rotary pan granulator, and subsequently or simultaneously adding a suitable flow modifier.
  • the resultant agglomerate is dried and further coated with the water-soluble or water-dispersible barrier material, and optionally granulated with further flow modifier and dried.
  • a further subject of the invention is a particulate detergent composition comprising organic detergent surfactants and other detergent ingredients, and comprising a granular composition as defined previously.
  • the particulate laundry detergent composition of the invention may suitably comprise from 5 to 60 wt% of organic surfactant, from 10 to 80 wt% of detergency builder, from 0.1 to 10 wt%, preferably from 0.5 to 5 wt%, of a granular composition as defined previously, and optionally other detergent ingredients to 100 wt% .
  • Example 1 photobleach granules using citric acid carrier and starch barrier material
  • the formulation of the granular material was as follows
  • Example 2 photobleach granules using citric acid carrier and polyvinyl alcohol barrier material
  • Photobleach granules were prepared as in Example 1 but the starch solution was replaced by polyvinyl alcohol solution (concentration 10% by weight) .
  • the final formulation of the granular material was as follows :
  • Granules were prepared by the process of Example 1 but using soda ash instead of citric acid.
  • Granules were prepared by the process of Example 1 but using sodium tripolyphosphate instead of citric acid. Wash protocol
  • Cotton fabric pieces of dimension 10 inch x 10 inch (25.4 cm x 25.4 cm) were placed in trays, each together with 2 kg of water and one of the following photobleach granular compositions :

Abstract

Cette invention se rapporte à une composition granulaire conçue pour être incorporée dans une composition de détergent particulaire, cette composition comprenant: (a) un ingrédient coloré ou fluorescent, par exemple un agent de photoblanchiment, tel que du sulfonate de phtalocyanine d'aluminium ou de zinc; (b) un matériau véhiculant pour l'ingrédient coloré ou fluorescent, constitué par un acide organique α-hydroxy, de préférence de l'acide citrique; (c) un matériau barrière hydrosoluble ou dispersable dans l'eau, tel que de préférence un alcool de polyvinyle ou d'amidon hydrosoluble; et (d) un modificateur d'écoulement inorganique, par exemple de la silice et/ou du kaolin. L'ingrédient coloré ou fluorescent est de préférence dispersé sur l'acide α-hydroxy, lequel est mélangé à une partie ou à la totalité du modificateur d'écoulement inorganique, et le tout est traité avec le matériau barrière, puis granulé avec le modificateur d'écoulement inorganique restant. Ce matériau granulaire peut être incorporé dans des compositions de détergents particulaires, dans lesquelles il présente une tendance réduite à laisser des taches sur les tissus lavés.
