  • Patent number: 8192727
    Abstract: The present invention is directed to a series of sorbitol esters that have two different molecular weight ester chains, one solid and one liquid, which when combined into a single molecule make a polymer that is solid, but has very unique flow properties. These materials find applications as additives to formulations in personal care products where there is a desire to have a structured film (provided by the solid fatty group) and flow properties, (provided by the liquid fatty group). These compounds by virtue of their unique structure provide outstanding skin feel.

  • Patent number: 8143368
    Abstract: Hydrolytically degradable polymers in the form of biodegradable disposable medical devices for use in medicine and laboratories such as syringes, test tubes, catheters, tubing, trays, medical fabrics, and gloves are described. The devices are formed in whole or in part of a hydrolytically degradable polymer. In the preferred embodiment, the devices or structural components thereof degrade in a period of weeks to months, preferably within a year and more preferably within six months of exposure to aqueous solutions. Conventional hydrolytically degradable polymers may be utilized or these may be modified to increase mechanical or processing characteristics, for example, using a polyfunctional branching agent and/or a chain extending agent. In one embodiment, the hydrolytically degradable polymer is a member of a new class of polyesters comprising an aliphatic dicarboxylic acid, an aliphatic diol and optionally, one or more bifunctional fatty acids such as ricinoleic acid and/or castor oil.

  • Patent number: 8129478
    Abstract: Biodegradable polymers formed from biodegradable polyester-based prepolymers, to which ring-structured anhydrides which have different hydrophobicities have been connected, and which are either coupled to form linear thermoplastic polyester anhydrides or cross-linked to form network-structured polyester anhydrides. It is possible to adjust widely the degradation rate and mechanism of the polymers and thus they can be used, for example, in the controlled dosing of pharmaceutical ingredients, for tissue technological applications, in surgery and in bioactive composites.
