Abstract: A biodegradable fiber that is formed from a thermoplastic composition that contains polylactic acid, a plasticizer, and a compatibilizer is provided. The compatibilizer includes a polymer that is modified with a polar compound that is compatible with the plasticizer and a non-polar component provided by the polymer backbone that is compatible with polylactic acid. Such functionalized polymers may thus stabilize each of the polymer phases and reduce plasticizer migration. By reducing the plasticizer migration, the composition may remain ductile and soft. Further, addition of the functionalized polymer may also promote improved bonding and initiate crystallization faster than conventional polylactic acid fibers. The polar compound includes an organic acid, an anhydride of an organic acid, an amide of an organic acid, or a combination thereof. Such compounds are believed to be more compatible with the generally acidic nature of the polylactic acid fibers.

Abstract: A biodegradable, substantially continuous filament is provided. The filament contains a first component formed from at least one high melting polyester and a second component formed from at least one low melting polyester. The low melting point polyester is an aliphatic-aromatic copolyester formed by melt blending a polymer and an alcohol to initiate an alcoholysis reaction that results in a copolyester having one or more hydroxyalkyl or alkyl terminal groups. By selectively controlling the alcoholysis conditions (e.g., alcohol and copolymer concentrations, catalysts, temperature, etc.), a modified aliphatic-aromatic copolyester may be achieved that has a molecular weight lower than the starting aliphatic-aromatic polymer. Such lower molecular weight polymers also have the combination of a higher melt flow index and lower apparent viscosity, which is useful in the formation of substantially continuous filaments.

Abstract: Methods for adjusting the solubility of a botanical oil in water, along with the resulting modified botanical oil and related products (e.g., treatment compositions, wipes, absorbent articles, etc.) are provided. In one embodiment, the method includes reacting the botanical oil to form a reactive product (e.g., having a hydroxyl group); and attaching a hydrophilic end group (e.g., a carboxylic acid, a carboxylic acid salt, a sugar, etc.) on the reactive product to form a modified botanical oil. The modified botanical oil generally, in most embodiments, has a greater solubility in water than the botanical oil (e.g., a solubility in water of about 10 grams per 100 grams of water or greater, such as completely soluble in water). The botanical oil includes, in one particular embodiment, an essential oil, such as those essential oil that include at least one terpene compound.

Abstract: This invention describes a general binding assay method to detect the presence and quantity of analyte in a sample. The method uses time-resolved up-converting fluorescence detection technique to provide highly sensitive detection without using expensive optical components such as band-pass optical filters. The method uses pulsed long wavelength light for excitation and time-delayed luminescence detection, resulting in little interferences from sample matrices. Furthermore, the usage of long wavelength excitation light requires simpler sample preparation and processing such as removal of red blood cells, which otherwise will significantly interfere with excitation efficiency of the luminescence probes.
