The present invention provides a tooth whitening composition having a transparent first component that is a carrier compound and a transparent second component that is an oxidizing compound which when applied to a stained tooth and exposed to actinic light is activated to facilitate tooth whitening. The invention also provides a method for light-activated tooth whitening which comprise applying a tooth-whitening composition to one or more teeth and exposing said composition to actinic light to activate said oxidizing compound. The present invention further provides a device for tooth whitening which has a light source, at least one optical output, a projection means for holding and positioning said optical output outside of a patient's mouth in a manner so as to provide approximately simultaneous and uniform illumination of a patient's front teeth by said optical output; and a connection means for connecting said light source to said optical output. The invention also provides methods of using the device.

Described is a method of sanitizing animal carcasses using aqueous streams having an antimicrobial composition added to the stream. Preferably, the antimicrobial composition includes a mixture of one or more carboxylic acids having up to 18 carbon atoms and one or more peroxycarboxylic acids having up to 12 carbon atoms, preferably a mixture of a C 2 -C 4 peroxycarboxylic acid and a C 8 -C 12 peroxycarboxylic acid. Also described is a novel antimicrobial composition adapted for sanitizing animal carcasses containing a mixture of one or more C 2 -C 4 peroxycarboxylic acids and one or more C 8 -C 12 peroxycarboxylic acids and an alpha-hydroxy mono- or dicarboxylic acid.

Comparison of 99mTc-labeled phosphate and phosphonate agents for skeletal imaging.

A garment stain removal product and process is disclosed. The product includes a liquid cleaning composition which contains water, an organic solvent and a surfactant, an absorbent stain receiver, and a sonic or ultrasonic wave generating source for imparting sonic or ultrasonic waves onto stains on textiles. The sonic or ultrasonic wave source is, for example, a hand-held, pen-shaped device with a directed point to focus the sonic or ultrasonic waves at the stain to be removed.

A stable viscous liquid bleach that may be safely applied directly to stubborn stains is prepared by adding certain anionic or nonionic surfactants to aqueous solutions containing up to 30% by weight hydrogen peroxide. The viscosity of the aqueous hydrogen peroxide solution is adjusted to be within the range of about 60 cps - 6,000 cps by addition of a water dispersible copolymer of an alpha-beta monoolefinically unsaturated lower aliphatic carboxylic acid crosslinked with a polyether of a polyol selected from the class consisting of oligo saccharides, reduced derivatives thereof in which the carbonyl group is converted to an alcohol group and pentaerythritol, the hydroxy groups of said polyol which are modified being etherified with allyl groups, said polyol having at least two allyl groups per polyol molecule.

The invention relates to the dispensing of hydrogen peroxide into a clothes dryer. The aqueous hydrogen peroxide is placed into a container with a microporous, hydrophobic surface which is heated whereby the hydrogen peroxide is vaporized and delivered to the interior of the dryer where it is available to bleach textiles.

Low bulk density, soda ash-based, nonphosphate laundry detergents are prepared by (a) loading nonaqueous liquid surfactant onto substantially anhydrous, hydratable soda ash particles, (b) turbulently dispersing the surfactant-loaded particles into an inert gaseous medium while wetting the dispersed particles with an atomized stream of dilute aqueous sodium silicate or with separate atomized streams of water and concentrated aqueous sodium silicate, and (c) recovering the resultant particulate detergent. Preferably, natural soda ash is used in the process, and both nonionic and anionic surfactants are loaded onto the soda ash, in that order.
