Publication number: 20240245780Abstract: Pharmaceutical compositions comprising poorly water-soluble drugs (PSDs) and sucrose acetate isobutyrate (SAIB). The compositions are amorphous solid solutions or amorphous solid dispersions where the PSDs are present in the molecular or the amorphous state in the SAIB. The PSDs in amorphous form in the amorphous solid solutions can be stable against crystallization on exposure to elevated temperature and humidity conditions. Oral dosage forms containing the compositions are characterized by a higher dissolution rate in water, a higher serum maximum concentration (Cmax), and/or a greater area under the curve (AUG) than an equivalent oral dosage form without the SAIB.Type: ApplicationFiled: May 10, 2022Publication date: July 25, 2024Applicants: Eastman Chemical Company, The Texas A&M University SystemInventors: Ziyaur RAHMAN, Eman M.

Publication number: 20240239920Abstract: Densified textile aggregates are co-fed with a fuel into a partial oxidation gasifier. High solids concentrations in the feedstock composition can be obtained without significant impact on the feedstock composition stability and pumpability. A consistent quality of densified textile derived syngas can be continuously produced, including generation of carbon dioxide and a carbon monoxide/hydrogen ratio while stably operating the gasifier and avoiding the high tar generation of fluidized bed or fixed bed waste gasifiers and without impacting the operations of the gasifier. The densified textile derived syngas quality, composition, and throughput are suitable for produce a wide range of chemicals and polymers, including methanol, acetic acid, methyl acetate, acetic anhydride, and cellulose esters through a variety of reaction schemes in which at least a portion of the chemical or polymer originates with densified textile derived syngas.Type: ApplicationFiled: February 5, 2024Publication date: July 18, 2024Applicant: Eastman Chemical CompanyInventors: William Lewis Trapp, Justin William Murphy, Nathan Mitchell West

Publication number: 20240191059Abstract: The present invention provides a non-phthalate, highly sustainable plasticizer, with performance comparable to or better than the existing orthophthalate market leader (DINP) and non-phthalate market leader (DOTP) at a lower cost position. The novel plasticizers are terephthalate ester and epoxidized oil compositions and dibenzoate ester and epoxidized oil compositions. The novel plasticizer compositions are produced by blending a fast fusing terephthalate diester or dibenzoate ester with an epoxidized oil. The presence of the terephthalate diester or the dibenzoate ester in the blend imparts better physical properties and performance properties over the ester or epoxidized oil components alone.Type: ApplicationFiled: April 13, 2022Publication date: June 13, 2024Applicant: Eastman Chemical CompanyInventor: Thomas John Markley
