Abstract: A class of antioxidant compositions include benzotriazole phenolate salts with substituents either ortho to the phenol hydroxide group and/or para to the phenol hydroxide group can be prepared from substitued benzotriazole phenols. The ortho substituent group can be a simple hydrocarbon, alkoxy or amino group, or the ortho substituent group can be a linking group, linking the benzotriazole phenolate to another benzotriazole phenolate group.

Abstract: Polymeric compositions include at least one polymer that is free of ester linkages and an additive that is a benzotriazole phenolate salt with substituents either ortho to the phenol hydroxide group and/or para to the phenol hydroxide group. The substituted benzotriazole phenolate salts can be prepared from substitued benzotriazole phenols. The ortho substituent group can be a simple hydrocarbon, alkoxy, or amino group, or the ortho substituent group can be a linking group, linking the benzotriazole phenolate to another benzotriazole phenolate group.

Abstract: A facemask is disclosed that can be reliable secured to a wearer's face with a robust, reliable skin-friendly adhesive, obviating the need for straps or other connection to the wearer's ears. The facemask includes one or more contact sheets and a filtering web arranged on or within the contact sheet(s). The adhesive is disposed about the periphery of the face contacting cover sheet and/or filtering web and ensures an adequate seal on the mask perimeter when the mask is donned.
