Abstract: The present invention provides a process for making detergent granules by forming a doughy mass comprising surfactant and/or water-soluble organic polymer and/or detergent builder, and then granulating by mixing a deagglomerating agent into the doughy mass at a high shear rate. Neutral or alkaline salt, detergent builder and other conventional detergent ingredients can be, and preferably are, kneaded into the doughy mass before addition of the deagglomerating agent. The deagglomerating agent is a fine powder having a mean particle size of less than about 200 microns and is most preferably sodium aluminosilicate.

The composition exhibits good grease removal and foaming while manifesting mildness to the skin.

Abstract: A process for producing high active detergent particles including reacting the acid form of anionic surfactant with an alkali metal hydroxide solution in a continuous neutralization system, and adding to the system an .alpha.-aminodicarboxylic acid selected from the group consisting of glutamic acid, aspartic acid, aminomalonic acid, aminoadipic acid, and 2-amino-2-methylpentanediotic acid, or their salts. Mono- and disodium glutamate are preferred.

Abstract: This is a bleach granule comprising the nonylamide of peroxyadipic acid with a average particle size of about 0.1 to 260 microns, bleach-stable surfactant, and a hydratable, NAPAA-compatible material, e.g. sodium sulfate. The bleach granules are stable and are effective bleaching agents.

Abstract: This is a process for making high active alkyl sulfate particles which are dispersible in cool or cold water. The process includes applying mechanical work to low moisture, neutralized C.sub.12-18 alkyl sulfate paste. Included are detergent particles made by this process and a method for washing fabrics at cool or cold water temperatures using detergent particles made by this process.

Abstract: An antimicrobial composition comprising endo-.beta.-N-acetylglucosaminidase and/or endoglycopeptidase, and ruminant stomach lysozyme is presented. A method for destroying or removing microbes by treatment with these enzymes is also presented.

Abstract: A process for making coated detergent granules by producing detergent granules and then uniformly distributing finely divided powder onto the surfaces of the detergent granules by means of an electrostatic charging and delivery system. The detergent granules are comprised of from about 10 to 20 weight % water so that the finely divided powder adheres to the moist detergent granules even after the electrostatic change dissipates.

Abstract: This invention relates to a process for applying water-soluble dye or water-dispersible pigment to stabilized bleach activator extrudates in a manner which avoids agglomeration and allows even coating of the bleach activator extrudates. This is accomplished by adding water-soluble hydratable material and the dye or pigment to an aqueous solution, and then distributing the aqueous solution on the bleach activator extrudates. The bleach activator extrudates comprise specific peroxygen bleach activators and select binder materials. This invention also relates to colored bleach activator extrudates made according to this process.

Abstract: Flakes of a hydrophilic solid organic material, e.g., polyethylene glycol are formed from a melt of said solid organic material on a belt cooler. The process is improved by wetting the belt cooler with water and/or an organic, low molecular weight, hydrophilic liquid to maintain contact between flake and belt during rapid cooling.
