Provided is a kit or system (100) for preparing a peroxide composition with increased viscosity with a pH in the range of 7 to 12 in an almost instantaneous method. For example, the kit or system may be used to provide an almost instantly obtainable (hydro)gelled peroxide composition. The system comprises a first aqueous composition (102) comprising a peroxide agent. The first aqueous composition has a first pH of less than 7. The system further comprises a second composition (104) comprising a basic agent. The second composition is separate from the first aqueous composition. A pH induced thickener is included in the kit or system separate from the second composition. The peroxide composition is obtainable by combining the parts of the kit or system. The pH induced thickener is capable of increasing the viscosity of the peroxide composition upon subjecting it to the pH in the range of 7 to 12. The kit or system has sufficient basic agent for the peroxide composition to cause the pH in the range of 7 to 12. A method for preparation and use of the kit or system is also provided.

Antimicrobial compositions comprising one or more compound components generally recognized as safe for human consumption, and related methods of use, such compositions and methods as can be employed in a wide range of agricultural, industrial, building, pharmaceutical and/or personal care products and applications.

Disclosed is a dental bleaching gel composition with high electric conductivity. It was the object of the present invention to provide a bleaching gel composition that is less initiating than prior art gels, and is highly efficient such that it can bleach within shorter time. The composition includes a peroxide, or a peroxide releasing compound such as carbamide peroxide, sodium perborate, or sodium percarbonate as a bleaching agent, a cross-linked polyacrylate polymer as a thickening component, and electrical conductivity enhancing ingredients such as electrolytes.

A kit includes a multi-phase oral composition for whitening teeth and an electromagnetic radiation source. The multi-phase oral composition for whitening teeth includes from about 0.002% to about 30%, by weight of the multi-phase oral composition, of a discontinuous aqueous phase having a bleaching agent, where a concentration of the bleaching agent is up to 10%, by weight of the multi-phase oral composition, and at least about 50%, by weight of the multi-phase oral composition, of a continuous hydrophobic phase of petrolatum. The electromagnetic radiation source is capable of directing electromagnetic radiation with one or more wavelength in the range from about 200 nm to about 1700 nm toward at least one tooth. The electromagnetic radiation source emits electromagnetic radiation in a range from about 100 mW/cm.sup.2 to about 250 mW/cm.sup.2.
