Abstract:
A laminate film including a first polylactic acid layer; a second metal-receiving layer including PVOH, EVOH, or a blend thereof on a side of the first polylactic acid layer; and a metal layer deposited on a side of the metal-receiving layer opposite the polylactic acid layer. The metal-receiving layer may be coextruded with the polylactic acid first layer or may be a coating applied to one side of the polylactic acid first layer. This laminate film exhibits excellent gas and moisture barrier properties, appearance, and metal adhesion. It may also include a heat sealable or winding improving layer on the side opposite the metal receiving-layer of the first polylactic acid layer.
Abstract:
Disclosed herein are methods of reducing irritation associated with personal care and cosmetic compositions comprising 1,3-propanediol, wherein the 1,3-propanediol in said personal care or cosmetic composition has a bio-based carbon content of about 1% to 100%. In addition, it is preferred that the 1,3-propanediol be biologically-derived, and wherein upon biodegradation, the biologically-derived 1,3-propanediol contributes no anthropogenic carbon dioxide emissions to the atmosphere.
Abstract:
The present invention is a biodegradable resin composition comprising a sparingly hydrolyzing biodegradable resin (A) and an ester decomposition promoter (B), the ester decomposition promoter (B) being a copolymerized polyester that contains a segment (X) of a sparingly hydrolyzing polyester and a segment (Y) of an easily hydrolyzing polyester at a weight ratio of 10/90
Abstract:
Disclosed herein are food and flavorant compositions comprising 1,3-propanediol, wherein the 1,3-propanediol in said compositions has a bio-based carbon content of about 1% to 100%. In addition, it is preferred that the 1,3-propanediol be biologically-derived, and wherein upon biodegradation, the biologically-derived 1,3-propanediol contributes no anthropogenic CO2 emissions to the atmosphere.
Abstract:
A process for providing detergent compositions comprising synthesizing mono and di esters from biologically derived 1,3-propanediol an incorporating said esters into detergent formulations. The basic process involves producing and purifying biologically derived 1,3-propanediol, synthesizing mono and di esters by the condensation of 1,3-propanediol with an acid using a catalyst, recovering the ester and incorporating said ester into a detergent formulation. The compositions made from the biologically derived 1,3-propanediol are also encompassed by the invention.
Abstract:
Described is a process for increasing the molecular weight of a composition of one or more biodegradable aliphatic and/or aliphatic-aromatic thermoplastic polyesters of the dicarboxylic acid/diol type, comprising the reactive extrusion of said polyesters with organic peroxides; and a composition obtained by the process.
