Embodiments of the present invention provide a foaming alcohol-based hand sanitizer having good foaming and virucidal characteristics by combining a linear siloxane polyether having a siloxane backbone with between 20 and 40 repeating siloxane units, two polyethylene glycol backbones each having between 10 and 20 repeating ethylene oxide units, and two polypropylene glycol backbones each having between 0 and 10 propylene oxide units, an alcohol such as ethanol or isopropanol, and water, where the hand sanitizer comprises between 0.01% and 5% linear siloxane polyether, more than 85% alcohol, and the balance is water.

This application provides, among other things, novel aqueous oral care compositions useful for combining and delivering poorly compatible ingredients, in particular, chlorhexidine and polyphosphate salts, by formulating the composition with a surfactant.

The inventive subject is directed towards ready-to-use topical cosmetic formulations that include at least one defensin present in sub-antimicrobially effective concentrations. Surprisingly, even at such low concentrations, defensins recruit LGR6+ stem cells from hair follicles to the interfollicular space. Including defensins in the inventive topical cosmetic formulations may reduce one or more of wrinkle depth, wrinkle length, wrinkle width, pore size, irregularity in texture of a skin surface, oiliness, brown spots, and red spots in non-injured skin, thus reducing apparent age.

The present disclosure discloses an antibacterial glucose-based composite nanoparticle and a processing method and use thereof, and belongs to the technical field of processing of modern food. According to the present disclosure, the antibacterial composite nanoparticle is prepared by using a particle surface positioning modification technology and a physical field charge transfer technology with a natural glucose-based nanoparticle as a raw material. The obtained antibacterial composite nanoparticle has a particle size of 50-1,000 nm, a surface zeta potential of 0 to −10 mV and a broad-spectrum antibacterial rate of greater than 98%. The shelf life of food can be effectively prolonged to prevent spoilage of products. The antibacterial composite nanoparticle can be used in food, textiles, daily chemicals, medicine and many other fields, and has a wide application prospect.

A Swertia chirata extract obtained by extracting with supercritical CO.sub.2 an alcoholic extract of Swertia chirata, and to a cosmetic composition including such an extract having in particular an anti-ageing effect for the skin. Also, administering such an extract in a cosmetic method for preventing and/or reducing skin ageing and a cosmetic method for hydrating the skin and/or improving the barrier function of the skin
