Description

DETERGENT PARTICLE FIELD OF THE INVENTION This invention relates to detergent compositions and components thereof that provide suitable product supply and dissolution.

BACKGROUND OF THE INVENTION It is well known that the use of effervescence systems in pharmaceutical tablets and detergents provides an effective dissolution of the ingredients of the tablets in water. Recently effervescence systems have been incorporated in detergent powders to provide improved dissolution. It is known that effervescence occurs when the effervescence system is in contact with water; therefore, to optimize the effervescence capacity of the system in use, contact with water or moisture during manufacturing or storage should be avoided. Various techniques have been suggested to stabilize the effervescence systems in wet conditions. For example, the effervescent pharmaceutical powders or tablets, in particular, can be densified by compression or coated to minimize contact with water or moisture; however, these tablets or powders are often difficult or expensive to produce, and do not always result in satisfactory effervescence in use. In particular, the dissolution or the supply of the ingredients of the tablets or powders can be reduced or delayed. Thus, there is still a need to provide improved effervescence systems for granular or solid detergents, which are stable under moisture conditions, which are produced easily and at low cost, and which provide excellent dissolution or supply of the detergent ingredients. On this occasion, the inventors have discovered that when an effervescence system or component thereof is intimately mixed with specific stabilization material, a very stable storage effervescence particle is obtained, which has a controllable effervescence in use, which also results in an improved solution and supply. It is believed that the specific stabilizing material reduces the interaction of the effervescence system with moisture. In particular, it has been found that effervescence particles having an average particle size of 75 microns to 2 cm offer improved effervescence and storage stability. The particle can be used in cleaning compositions or cleaning procedures. The particle is useful specifically in non-aqueous liquid detergent compositions and in solid detergent compositions, including detergent granules, lozenges, chips and tablets. In addition, the particle preferably contains one or more detergent active ingredients, which may be part of the stabilizing agent. It has been discovered that the particle can control the release of these active ingredients. In this way, depending on the exact nature of the particle, the effervescence and dissolution of the active ingredients can occur immediately upon contact with water, or the onset of effervescence or the dissolution of some of the active ingredients may be delayed, As required. This can result in improved performance of the active ingredients and in improved cleaning performance of the cleaning composition or particle. Also, the inventors have discovered that when the stabilizing particle comprises specific nonionic surfactants, in particular nonionic polyhydroxy fatty acid amides and / or nonionic condensation products of aliphatic alcohols, in use, the particle has the additional benefit of which produces a very rapid foaming at the beginning of the laundry or dishwashing process, which is stable during the process. In addition, the inventors have discovered that the incorporation of one or more additional cleaning active ingredients in the effervescent particle results in a very fine dispersion of the active ingredients in the washing liquid., which improves the dissolution and / or cleaning performance of said active ingredients. In particular, the inventors have discovered that the incorporation of a bleaching species and in particular bleaching activators result in an improved bleaching performance and in particular a reduction in the risk of damaging frayed fabrics. It is believed that this is due to the improved supply and dissolution of the bleach or bleach activator species, which produce a reduced deposit of these ingredients in the fabric and, therefore, a reduced risk of damaging the fabric.
