Propolis propolis has approximately 50 constituents, primarily resins and vegetable balsams (50%), waxes (30%), essential oils (10%), and pollen (5%). Propolis also contains persistent lipophilic acaricides, a natural pesticide that deters mite infestations. In neotropical regions, in addition to a large variety of trees, bees may also gather resin from flowers in the genera "Clusia" and "Dalechampia", which are the only known plant genera that produce floral resins to attract pollinators. "Clusia" resin contains polyprenylated benzophenones. In some areas of Chile and Argentina Andean valleys, propolis contains viscidone, a terpene from "Baccharis" shrubs, and in Brazil and Paraguay, naphthoquinone epoxide has
Fugitive glue some object—product sample or a return envelope—is glued to another, usually paper, object—a mailing envelope or a magazine. They tend to perform best on smooth, non-porous surfaces. In these applications, fugitive glues are not resealable pressure-sensitive adhesives such as are used on pressure-sensitive tapes or post-it notes, although resealable formulations are available. Fugitive glues are usually available in hot melt or latex form, with low VOC emissions. They can be also applied in liquid form. Fugitive glue Fugitive glue, also called credit card glue, E-z-release glue, or (colloquially) booger glue, snot glue, or gooey glue, is a low-tack adhesive that
