The lotion may have a preservative system having benzoic acid and/or a salt thereof, succinic acid and/or a salt thereof, and phytic acid and/or a salt thereof. The lotion may also have a surfactant, pH buffering system, and a pH of about 3.5 to about 5.

Abstract: A dry salt therapy device includes a blower, an exhaust passage fluidly coupled to the blower, a grinding chamber configured to aerosolize salt, and a salt vent fluidly coupling the exhaust passage and the grinding chamber. A flow structure may be provided. The grinding chamber may have a particular aspect ratio, tip clearance, or floor clearance. Salt may be delivered to a user without contacting the user, the salt being delivered in a jet having a particular diameter at a particular distance. The device can include a converging-diverging nozzle in the exhaust passage. The salt vent may protrude into a center of a flow of air through the exhaust passage.

Abstract: A polysulfone has sulfone units that are separated by alkylene units in a polymer chain or a copolymer chain where the alkylene units have at least four carbons between sulfone units. The alkylene units can include an ethenylene unit separated from the sulfone units by at least one methylene units. The polysulfones can be crosslinked for enhanced thermal stability. Membranes can be formed from the polysulfones.

Abstract: A method of carrying out a metathesis reaction includes the combination of at least one alkene or non conjugated diene with a Ruthenium-based catalyst with an cyclic(alkyl)(amino)carbene ligand to form a reaction mixture, heating the reaction mixture to a temperature of 100° C. or greater in the absence of a solvent in bulk conditions, and mechanically stirring the reaction mixture. The reaction can be an ADMET, ROMP, a metathesis ring-closure or an olefin exchange reaction.

Abstract: Poly(sulfonic acid)s including a multiplicity of sulfonic acid units separated by alkylene units in a polymer chain or a copolymer chain, the poly(sulfonic acid) having a degree of crosslinking in a range of from about 0.1 to about 30 percent. Methods of preparing poly(sulfonic acid)s having improved mechanical integrity. The methods may include synthesizing a poly(sulfonic acid) by acyclic diene metathesis (ADMET) polymerization and reacting a plurality of double bonds afforded by the ADMET polymerization with a crosslinker. The crosslinking reaction may achieve a degree of crosslinking in a range of from about 0.1 to about 30 percent.

Abstract: Embodiments of the invention relate to providing online product research. Data related to an activity performed by a consumer at a first electronic commerce website is collected. The collected data includes information about a first product, and the information about the first product is stored as product research data. The product research data is associated with the consumer. It is detected that the consumer is accessing a location in a second electronic commerce website that includes information about a second product. The product research data is searched for data related to the information about the second product. The information about the first product is located in response to searching the product research data for data related to the information about the second product, and the consumer is presented with the information about the first product along with the information about the second product.

Abstract: An automatic razor blade sharpener simultaneously sharpens and sanitizes multiple edges of a spring-loaded disposable razor blade cartridge without edge overheating by lubricated gentle contact of the blade edges with a moving rubber or polymeric compliant belt that is motor driven. The disposable razor blade handle is set in a cradle aperture, which is spring loaded against the moving belt. A sanitizing and lubricating liquid is dispersed from a container between the razor blade edges and the moving belt forms a thin liquid layer on the belt surface. The liquid layer is illuminated by transversely located light illuminator and the reflected light is received by a transversely located sensor. Deep grooves in the blade cutting edge reduce this reflection, indicating an overly worn blade. The absence of reflection actuates an LED, informing the user that the thin liquid film has evaporated or spilled out, or that the container lacks a sufficient quantity of sanitizing and lubricating liquid.

Abstract: An automatic razor blade sharpener simultaneously sharpens multiple edges of a spring-loaded disposable razor blade cartridge by gently contacting the blade edges with a moving rubber or polymeric compliant belt that is motor driven. The disposable razor blade handle is set in a cradle aperture, which is spring loaded against the moving belt. A timer terminates the blade sharpening operation, indicated by a green LED. A liquid is dispersed on the moving belt forming a thin liquid layer on the belt surface, illuminated by transversely located light illumination and the reflected light is received by a transversely located sensor. When the blade contacts the thin liquid layer, deep grooves in the blade cutting edge reduce this reflection indicating that the blade is too worn to be sharpened and a red LED light is indicated. Absence of reflection indicates that the thin liquid film has evaporated or spilled out.
