A composition and a method for clearing tissue for subsequent three-dimensional analysis. The clearing composition comprises: (1) a homogenizing agent such as N-methylglucamine, urea, or ethylenediamine; (2) a cytoplasmic, water-soluble refractive index adjusting agent such as iohexol, sodium thiosulfate, or polyethylene glycol; and (3) a membrane, lipid-soluble RI adjusting agent such as 2,2′-thiodiethanol (TDE) or propylene glycol. The tissue clearing composition is particularly suitable for use with long-term fixed human tissues.

A roll of cleaning fabric is used for cleaning printing cylinders of a printing system. The cleaning fabric (13) is impregnated with a cleaning composition containing an organic solvent and a cellulose solubilizer. The roll may be wound around a core (14) and inserted in a removable sealing bag (15) configured to seal around the roll (12) of cleaning fabric (13) in order to prevent the cleaning composition from evaporating before use.

Disclosed herein are the methods of using di-cationic or di-anionic compounds, which are derived from primary amine through an aza-Michael addition with an activated olefin, in a corrosion control composition to mitigate corrosion of a surface in a water system. The disclosed methods or compositions are found to be more effective than those methods or compositions including commonly used single quaternary compounds for mitigating corrosion for a metal surface in water systems.

Provided is a cleaning agent composition for use in an adhesion process for applying an adhesive to a surface of a first member subjected to a dry treatment without a primer, and adhering a second member to the surface of the first member. The cleaning agent comprises a compound (A) having a (meth)acryloyl group and a liquid (B) having a boiling point of not higher than 200° C.

A metal resist cleaning liquid including a solvent, an organic acid, and a compound (B) represented by general formula (b-1) shown below (In the formula, Rb.sup.1 and Rb.sup.2 each independently represents an alkyl group having 1 to 3 carbon atoms; Rb.sup.3 and Rb.sup.4 each independently represents a hydrogen atom or an alkyl group having 1 to 3 carbon atoms; Yb.sup.1 represents a single bond, —O—, —S— or —N(Rb.sup.5)—; Rb.sup.5 represents a hydrogen atom or an alkyl group having 1 to 3 carbon atoms; Yb.sup.2 represents —O—, —S— or —N(Rb.sup.6)—; Rb.sup.6 represents a hydrogen atom or an alkyl group having 1 to 3 carbon atoms; and n represents an integer of 0 to 3). ##STR00001##

A solvent consisting essentially of: (A) a first component consisting of N,N-diethylacetamide (DEAC); (B) a second component consisting of 3-methoxy-N, N-dimethyl propionamide (M3DMPA); and (C) an optional third component consisting of one or more glycol ethers or glycol ether acetates; or a solvent consisting essentially of: (1) a first component consisting of one or more acyclic amides of Formula (I): and (2) an optional second component consisting of one or more of DEAC, M3DMPA, N,N-dimethylpropionamide, one or more glycol ethers or glycol ether acetates, and one or more cyclic amides of Formulae (II-IV). ##STR00001##

A cleaning composition is particularly suited for cleaning dirty intake valves. The cleaning composition includes a high solvency surfactant/solvent which has a Kb greater than 100 or polar Hansen solubility parameter greater than 6. The surfactant/solvent is combined with an organic carrier and a surfactant. A wetting agent may also be employed. The cleaning composition is added to the intake air as a mist as the engine is running.

A chemical composition for use in degassing of vessels is taught, said chemical composition including 1-10% by weight of an oxyalkylated dodecyl thiol; and 1-20% by weight of an alkyl di-substituted 9-decenamide. A method is further provided for degassing a vessel. The method includes charging said vessel with chemical composition and a carrier medium, wherein said chemical composition comprises 1-10% by weight of an oxyalkylated dodecyl thiol and 1-20% by weight of an alkyl di-substituted 9-decenamide.

A method for use of substituted dihydroxyterephthalic acid amides in detergents and cleaning agents, for improving detergent or cleaning performance with respect to bleachable stains.
