摘要:
Antimicrobial compositions and methods are disclosed. The antimicrobial compositions are particularly useful in providing antimicrobial capability to a wide-range of medical devices. In one aspect, the invention relates to a mild solvent coating using acrylate-type mild solution coating. These compositions include rheological modifiers as necessary. The compositions also include antimicrobial agents, which may be selected from a wide array of agents. Representative antimicrobial agents include cetyl pyridium chloride, cetrimide, alexidine, chlorexidine diacetate, benzalkonium chloride, and o-phthalaldehyde. Additionally, the compositions comprise one or more suitable mild solvents, such as a low molecular weight alcohol, alkane, ketone, and combinations thereof.

The present invention provides a method for preparing a lubricating composition, in particular a grease, the method at least comprising the steps of : a) providing a base oil composition optionally containing one or more additives; b) providing a solution of one or more alkyl- substituted quinolines or oligomeric derivatives thereof in a solvent; and c) adding the solution of step b) to the base oil composition of step a) at a temperature below 150°C.
摘要:
The invention is a C5-C12 cycloalkyl substituted phenylenediamine that provides deposit-control lubricant additives for organic materials including lubricating oil, gasoline, and diesel fuels. The invention improves the oxidative stability of the lubricants and fuels by adding cycloalkyl substituted phenylenediamines having one or more additional N-substituents.
摘要:
The invention relates to a new ultra-thin hydrophobic and oleophobic layer formed by self-assembly on a surface of a solid substrate having compounds of the general formula A-B in which A is a group having the formula (I) in which Z is C or N+; X is C-H or C-L, wherein L is an electroattractive group chosen from F, CF3, NO2 and N(CH3)3+; Y is H or CH3, or Y, together with X, forms a heterocycle of 5 or 6 atoms; T is NH, CO, CONH or NH2+U-, wherein U- is a soluble anion, and B is a C1-C20 aliphatic linear alkyl group replaced partially or completely by F. The invention also relates to a method for preparing said layer and its use as a barrier film.
