A process for the production of particulate detergents or premixes suitable for their production by application of a flowable acidic component to a particle consisting at least partly of an alkaline detergent ingredient selected from the group consisting of alkali metal silicates, alkali metal alumosilicates, alkali metal perborates, alkali metal percarbonates, and mixtures thereof, the percentage of acidic component applied being governed by the formula m/(m+m)=c&#xb7;l/r, where mis the weight of the acidic component, mis the weight of the particle, r is the radius of the particle and c is a factor of 5 length units to 10 length units.

Process for the production of particulate detergents

A process for preparing a detergent tablet having two or more regions comprises the steps of: (a) compressing a particulate composition comprising a detergent active component to form a compressed region of the tablet having a recess; (b) delivering to the recess a solution or melt comprising a mixture of at least one detergent active component and a fusible carrier material; and (c) solidifying the solution or melt.

Process for preparing detergent tablets having two or more regions

The invention relates to cosmetic and/or pharmaceutical preparations containing (a) water soluble &bgr;-(1,3) glucans that are substantially devoid of &bgr;-(1,6) links, and (b) deoxyribonucleic acids and their breakdown and degradation products.

Cosmetic and/or pharmaceutical preparations

Cosmetic and/or pharmaceutical preparations comprising dialkenyl carbonates

A process of washing textiles is presented involving the delayed release of ingredients from a detergent composition. The process involves first dissolving the detergent in water resulting in a pH below 8, slowly dissolving the coating on a coated alkalizing agent to raise the pH to above 8.5, and dissolving the polymeric acid coating on a detergent ingredient, due to the pH above 8.5, to release the ingredient into the wash water.

pH-controlled release of detergent components

The problem addressed by the invention was to provide a foam regulator system containing silicone and/or paraffin and bis-fatty acid amide which would have a low viscosity, which could be handled at low temperatures and which would have a low percentage content of non-foam-regulating ingredients. This problem was largely solved by an aqueous foam regulator emulsion containing 16% by weight to 70% by weight of active foam regulator based on paraffin wax and/or silicone oil, 2% by weight to 15% by weight of nonionic and/or anionic emulsifier and no more than 80% by weight of water. The foam regulator emulsion is preferably used for the production of partiulate foam regulator granules for use in detergents.

Aqueous foam regulator emulsion

Partially coated laundry detergent and cleaning product tablets having advantageous properties such as high hardnesses without adverse effect on short disintegration times and high resistance to edge fracture are achieved with relatively small amounts of coating agents if the coating covers only mechanically sensitive parts of the tablets.

Laundry detergent or cleaning product tablets with partial coating

A process for washing textiles is presented involving the delayed release of ingredients from a detergent composition. The process involves first dissolving the detergent in water resulting in a pH below pH 8, slowly dissolving the coating on a coated alkalizing agent to raise the pH to above pH to above pH 8.5, and above pH 8.5 the polymeric acid coating on a detergent ingredient dissolves, releasing the ingredient into the wash water. Also presented is a detergent composition for delayed bleaching of 1 to 40 percent by weight of a coated bleaching agent having a coating which dissolves slowly in water irrespective of the pH value, 0.5 to 15 percent by weight of a bleach activator coated with a polymeric acid, and 0.1 to 40 percent by weight of an acidifying agent. The process results in a delayed release of bleaching in the wash cycle.
