Abstract: The present invention encompasses topical oral care compositions comprising the combination of an anti-bacterial agent with an anti-inflammatory agent in an orally acceptable carrier for effective treatment and prevention of bacteria-mediated diseases and conditions in the oral cavity and for modulating host reaction to bacterial pathogens present in the oral cavity and to the toxins, endotoxins, inflammatory cytokines and mediators released by or prompted by these pathogens. The present invention also encompasses methods of use of these compositions comprising topical application to the oral cavity. The benefits of the present compositions and methods extend beyond treating and preventing oral bacterial infections in the oral cavity to promoting whole body or systemic health.

Abstract: Methods and devices for repelling insects are disclosed. The methods and devices provide personal protection from insect bites and insect landings, particularly mosquito bites. The methods and devices employ insect repellents such as pyrethroids at low (parts per billion) levels. The methods and devices effectively minimize the number of mosquitoes landing on a subject properly using the devices.

Abstract: The present invention relates to compounds having the general formula: [Poly]—[(L)z—[R—CHO]]y wherein [Poly] is a water-soluble, non-peptidic polymer component, L is an optionally present linking group, and RCHO is a substrate capable of interacting with one or more protease enzymes to reversibly inhibit said enzyme, and wherein said substrate comprises a peptide or peptide-like aldehyde. The index z is 0 when linking groups are absent and z is 1 when linking groups are present. The index y is at least 1. The inhibitors of the present invention are suitable for use in personal care compositions, inter alia, body washes, shampoos, and skin creams.

Abstract: The cosmetic compositions of the present invention provide a durable film after application that resists degradation over time. Cosmetic compositions of the present invention comprise: (A) an anhydrous mixture of: (1) silicone modified fluorinated polymers; (2) an organosiloxane resin; and (B) a volatile carrier.
