Abstract: The detergent additive granulate is a coated co-granulate containing at least one enzyme and at least one photobleaching agent. If a detergent, a component of which is such detergent additive granulate, is used for laundering, the photobleaching agent will not tend to adhere selectively to the laundry during the initial washing process.

Abstract: Particles containing enzyme or optical brightener in a mixture with particles containing peroxy bleach, surfactant or builder stabilized during storage by coating the former and/or the latter particles with clay, e.g. bentonite.

Abstract: An enzyme granulation process wherein an enzyme solution or suspension, filler, binder and cellulose or artificial fibres are granulated with fines and oversize particles of the granulate product particle the process being characterized by recirculation of fines without grinding, by grinding oversize particles then recirculation thereof, with the recirculated particles as a whole exhibiting a cumulative size distribution of the same general shape as the cumulative size distribution of the granulate product particles.

Abstract: Enzyme containing granulates containing less than 2% chloride and besides enzyme, coating materials, granulating aids and water, more than 35% w/w of a filler system consisting of from 5-70% w/w of the granulate composition of one or more water soluble sulphates, and 5-70% w/w water insoluble salts, especially sulphates, carbonates, phosphates or silicates. The granulates exhibit an excellent storage stability and a satisfactory physical strength.

Abstract: Immobilized enzyme granules prepared by mixing inert filler particles into an aqueous solution or dispersion of a water soluble binder, followed by granulating the mixture so as to form carrier granules. Enzyme is immobilized on the hydrophilic surfaces of the carrier granules. If not already insoluble in the medium for the intended enzymatic reaction, the binder in the granules is rendered insoluble, e.g., water insoluble.Proteins are preferred binder materials, and glutaraldehyde is the preferred reagent for bonding enzyme to the carrier granules and for water insolubilizing the binder.
