    摘要： The present invention provides low-density compositions, as well as particulates formed, at least in part, from such compositions. Preferred low-density materials include, for example, hollowspheres, low-density minerals, and low-density wood materials (e.g., sawdust). The low-density compositions of the invention can be formed as particulates, or cores, suitable for use in forming enzyme granules, e.g., marums, layered granules, prills, drum granules, agglomerated granules, or the like. Granules are disclosed having advantageous properties, e.g., low dusting, storage stable, fast enzyme-release profile, low true density, etc. The granules of the invention are especially useful, for example, in liquid detergents and cleaners, such as predominantly aqueous, liquid laundry detergents. In one embodiment, granules are provided having a true, or volumetric, density within a range of from about 0.95 to about 1.4 g/cm3. The granules can be economically produced in commercial quantities by way of a marumerization, drum granulation, fluid-bed spray-coating, pan-coating, or other suitable process.

    摘要翻译： 本发明提供了低密度组合物，以及至少部分地由这些组合物形成的微粒。 优选的低密度材料包括例如空心球体，低密度矿物质和低密度木材材料（例如锯屑）。 本发明的低密度组合物可以形成为适合用于形成酶颗粒的颗粒或芯，例如，粟粒，分层颗粒，颗粒，鼓颗粒，附聚颗粒等。 公开了具有有利性质的颗粒，例如低粉尘，储存稳定，快速的酶释放曲线，低真实密度等。本发明的颗粒特别有用，例如在液体洗涤剂和清洁剂中，例如主要是水性的， 液体衣物洗涤剂。 在一个实施方案中，提供具有约0.95至约1.4g / cm 3范围内的真实或体积密度的颗粒。 颗粒可以通过以下方式经济地生产商业数量：通过计数，鼓式造粒，流化床喷涂，泛涂或其它合适的方法。

    摘要： Granules are prepared containing an admixture of protein and salt layered over an inert particle. A preferred amount of salt is about between 63.7 and 84.3% of the total weight of the admixture. Proteins include pharmaceutically important proteins such as hormones, or industrially important proteins such as enzymes including proteases, amylases, lipases and cellulases capable of hydrolyzing substrates such as stains. Inert particles include inorganic salts, sugars, sugar alcohols, small organic molecules such as organic acids or salts, and minerals such as clays or silicates. A binder such as starch or polyethylene oxide may be mixed in with the admixture. A barrier material such as an inorganic salt or organic acid or salt may be in the admixture or coated over the admixture layer. A coating layer of a soluble or water dispersible film-forming polymer may be between the inert particle and admixture layer and/or over the admixture layer. The granules may also contain plasticizers, extenders, lubricants, pigments and anti-agglomeration agents. A preferred method for preparing the granules is by spraying a solution or slurry of the admixture onto the inert particles while fluidized in a fluid-bed coater.
