The compositions display excellant clarity with a percentage haze in the transmission mode of a Hunter Color analysis of less than 90%, preferably less than 50%.
Abstract:
Catalytic systems and methods for oxidizing materials in the presence of metal catalysts (preferably manganese-containing catalysts) complexed with selected macropolycyclic rigid ligands, preferably cross-bridged macropolycyclic ligands. Included are using these metal catalysts in such processes as: synthetic organic oxidation reactions such as oxidation of organic functional groups, hydrocarbons, and heteroatoms, including enantiomeric epoxidation of alkenes, enynes, sulfides to sulfones and the like; oxidation of oxidizable compounds (e.g., stains) on surfaces such as fabrics, dishes, countertops, dentures and the like; oxidation of oxidizable compounds in solution, dye transfer inhibition in the laundering of fabrics; and further in the bleaching of pulp and paper products.
Abstract:
A comprehensive stain removal kit includes various cleaning formulas, rinses and a super absorbent cloth for a regimen of stain removal. A stain removal guide is included to provide a stain removal regimen based on a stain and fabric classification. Cleaning formulas and rinses are alternately applied to the fabric in the presence of the super absorbent cloth in combination in accordance with a specified stain removal regimen. The cleaning formulas and rinses are absorbed into the super absorbent cloth with the stain material to completely remove stains, including combination stains. The kit is provided as a portable packet easily used or stored in a variety of locations where stain removal may be desired.
Abstract:
The aim of the invention is to improve the stability in storage of bleach activators of the quaternized amino alkyl nitrile type. To this end, the invention provides that a particle containing these bleach activators is enclosed in the most complete possible manner by an enclosing material.
Abstract:
The present invention relates to compositions and methods of whitening teeth of a subject in need thereof, by applying a safe and effective amount of a composition to a plurality of teeth, the composition comprising: a. a safe and effective amount of a bleaching agent; b. a safe and effective amount of a water insoluble solid phase; c. a safe and effective amount of a water soluble liquid phase; wherein the ratio of the water insoluble solid phase to the water soluble liquid phase is from about 1:4 to about 4:1; wherein the composition is applied for a sufficient period of time to achieve whitening; and wherein in one embodiment the composition has a Whitening Index of from about 0.5 to about 4. The composition optionally comprises a hydrophobically modified polymer. The present invention also relates to a delivery system comprising the present compositions used with an integral carrier, e.g. a strip material, dental tray or sponge material.
Abstract:
The present invention relates to a method for making a laundry detergent particle comprising from 10 to 60 wt % (anhydrous basis) zeolite, from 12 to 75 wt % polycarboxylate polymer, and optional additional ingredients to 100% by weight, said method comprising preparing an aqueous slurry comprising zeolite, and polycarboxylate polymer and optional additional ingredients and spray drying the slurry. The weight ratio of zeolite (anhydrous basis) to polycarboxylate polymer in the slurry is from 4:1 to 1:2. The particles have been found to reduce caking of detergent product whilst providing improved cleaning compared with the addition of the polycarboxylate polymer as a separate granule. The invention also includes detergent compositions comprising such particles. The particles may be incorporated into a finished detergent composition as part of an agglomerate or extrudate.
Abstract:
Clear, or translucent fabric softener compositions comprise fabric softener compound, principal solvent system, and high electrolyte levels. The high electrolyte level allows for a broader range of principal solvents to be used and/or reduces the incidence of increased viscosity when low levels of principal solvent are used. Phase stabilizers which are primarily ethoxylated hydrophobic materials can be used to reduce the amount of principal solvent that is needed and/or to stabilize the compositions in the presence of the highest levels of electrolyte. Specific phase stabilizers provide additional benefits including improved softening. Specific electrolytes provide improved results. Addition of primary solvents and/or phase stabilizers to the softener compounds can improve the viscosity/handling of the compounds and the ability to create the finished compositions.
