Fabric softening bentonite agglomerates for use in laundry detergents

Bentonite agglomerates are made which are suitable for use as a particulate fabric softener for softening washed laundry, especially when incorporated in detergent compositions by mixing with spray dried beads containing essential detergent composition components. Such agglomerates are in the Nos. 10-100 sieve range and are agglomerates of finely divided bentonite. The agglomerates are of a bulk density in the range of 7.0 to 0.9 g./ml., a moisture content of 8 to 13% and a frangibility less than 30, and includes 1 to 5% of a binder (sodium silicate). Also disclosed is a method for making the bentonite agglomerates by spraying an aqueous solution of the binder onto moving surfaces of finely divided bentonite until the moisture content thereof is elevated and the amount of binder for the agglomerate is sufficient, and drying the agglomerated particles to their "equilibrium moisture range". The agglomerated particles, which are irregular in shape and craggy of surface, when mixed with spray dried built detergent particles, do not objectionably segregate from them despite different bulk densities and some variations in particle sizes, and it is considered that the irregularity of shape and the cragginess of the agglomerated bentonite bead surfaces help to maintain the uniformity of distribution of the agglomerates in such fabric softening laundry detergent product.

Controlling viscosity of fabric softening heavy duty liquid detergent composition containing bentonite

A fabric softening heavy duty liquid detergent composition of controlled viscosity, which does not thicken excessively on aging, includes certain proportions of sodium linear higher alkylbenzene sulfonate, sodium alkyl polyethoxy sulfate, builder salt (highly preferably a mixture of sodium tripolyphosphate and sodium carbonate), finely divided swelling bentonite, low molecular weight polyacrylate and water. Such product is a stable pourable liquid of desired viscosity, density and pH, convenient for use in washing machines, for hand washing of laundry and for pre-treatment of badly soiled portions of items to be laundered. The presence of a small percentage of the polyacrylate in the composition prevents the viscosity thereof from increasing on storage to such an extent as would interfere with pourability.

Process for manufacturing bentonite agglomerates

Bentonite agglomerates are made which are suitable for use as a particulate fabric softener for softening washed laundry, especially when incorporated in detergent compositions by mixing with spray dried beads containing essential detergent composition components. Such agglomerates are in the No's. 10-100 sieve range and are agglomerates of finely divided bentonite. The agglomerates are of a bulk density in the range of 0.7 to 0.9 g./ml., a moisture content of 8 to 13% and a frangibility less than 30, and include 1 to 5% of a binder (sodium silicate). The described bentonite agglomerates are manufactured by spraying an aqueous solution of the binder onto moving surfaces of finely divided bentonite until the moisture content thereof is elevated and the amount of binder for the agglomerate is sufficient, and drying the agglomerated particles to their "equilibrium moisture range". The agglomerated particles, which are irregular in shape and craggy of surface, when mixed with spray dried built detergent particles, do not objectionably segregate from them despite different bulk densities and some variations in particle sizes, and it is considered that the irregularity of shape and the cragginess of the agglomerated bentonite bead surfaces help to maintain the uniformity of distribution of the agglomerates in such fabric softening laundry detergent product.

Self-healing bentonite sheet material composite drainage structure

The present invention relates to a layered water sealing article of manufacture including a layer of a flexible sheet material adhered to a layer of a composition comprising a non-hydrated water-swellable clay intimately contacted with a polypropene, polybutene, or mixtures thereof particularly useful as a water barrier. The water swellable clay composition can be adhered to the flexible sheet material in any manner, such as by extruding the composition in sheet form onto a layer of sheet material. The clay composition layer is sufficiently tacky to adhere to the sheet material on one major surface, and is sufficiently tacky for adherence to a wall, conduit, floor, roof, or other structure to be protected from water contact, on an exposed major surface in areas of potential water flow to prevent the seepage of water through the bentonite clay composition layer. In one embodiment, the clay composition layer includes a polypropene and/or a polybutene and an elastomer, such as butyl rubber, having sufficient resilience to stretch or expand with the expanding water-swellable clay composition upon hydration and to aid in maintaining the structural integrity and cohesiveness of the clay composition. In another embodiment, the clay composition layer comprises a water-swellable clay, an elastomer, and any plasticizer compatible with the elastomer.
