An excipient is a substance formulated alongside the active ingredient of a medication.They may be used to enhance the active ingredient’s therapeutic properties; to facilitate drug absorption; to reduce viscosity; to enhance solubility; to improve long-term stabilization (preventing denaturation and aggregation during the expected shelf life); or to add bulk to solid formulations that have ...
A preservative is a substance or a chemical that is added to products such as food products, beverages, pharmaceutical drugs, paints, biological samples, cosmetics, wood, and many other products to prevent decomposition by microbial growth or by undesirable chemical changes. In general, preservation is implemented in two modes, chemical and ...

Binder jet 3D printing, known variously as "Powder bed and inkjet" and "drop-on-powder" printing, is a rapid prototyping and additive manufacturing technology for making objects described by digital data such as a CAD file. Binder jetting is one of the seven categories of additive manufacturing processes according to ASTM and ISO. [1]
The first synthesis of ethyl lauroyl arginate hydrochloride and its antimicrobial properties were reported in 1976. In the earlies 1980s, LAMIRSA together with Consejo Superior de Investigaciones Científicas (CSIC, Barcelona) began to investigate a new approach to the control of pathogens in food through the application of cationic surfactants based on natural building blocks that inhibit the ...
Garcia-Benson adds: “Sugar [found in most preserves] also has preservative properties by reducing available water for microbial activity,” and once the jar is unsealed, it’s exposed to the ...
The Vacutainer was preceded by other vacuum-based phlebotomy technology such as the Keidel vacuum. The plastic tube version, known as Vacutainer PLUS, was developed at B-D in the early 1990s by E. Vogler, D. Montgomery and G. Harper amongst others of the Surface Science Group as US patents 5344611, 5326535, 5320812, 5257633 and 5246666.
