  • Publication number: 20180066123
    Abstract: Food and beverage containers and non-food contact packaging “peanuts” are made of foamed polystyrene (PS) containing 0.5% to 15% by weight of the photoaccelerant, such as for example benzophenone. This additive greatly accelerates the photodegradation of this novel packaging for a specialized use: the abatement of litter comprising single-serving containers and packaging “peanuts” disposed of on land and in water. Conditions controlling the distribution of the photoaccelerant in and the formation of the polystyrene foam are critical to the rate of the photodegradation of this packaging in the environment.

  • Patent number: 5213802
    Abstract: Pharmaceutical formulations employing novel non-allergenic, non-irritating, non-toxic, and non-digestible carriers, bases, or vehicles for topical or ingestible drug delivery are disclosed. The carriers are esterified alkoxylated polyols; preferred carrier embodiments include propoxylated glycerols which are esterified with C.sub.8 -C.sub.24 fatty acids. The non-digestibility of the esterified alkoxylated polyols permits, for example, delivery of medicaments taken orally directly to the lower gastrointestinal tract.
