To provide a composition for surface treatment capable of treating a surface of a polished object to be polished having both of a silicon-silicon bond and a nitrogen-silicon bond by sufficiently removing defects on the surface of the polished object to be polished. The composition for surface treatment contains a nonionic water-soluble polymer (A) having a main chain including only a carbon atom or a main chain consisting of a carbon atom and a nitrogen atom, and an anionic water-soluble polymer (B) having a main chain including only a carbon atom and a side chain having a sulfonic acid group or a group having a salt thereof or a carboxyl group or a group having a salt thereof, and being bonded to the main chain including only a carbon atom, and the composition is used for surface treatment of a polished object to be polished containing a silicon-silicon bond and a nitrogen-silicon bond and a pH of the composition is less than 9.0.

A cleaning agent composition for use in removal of an adhesive residue, the composition containing a quaternary ammonium salt and a solvent, wherein the solvent consists of an organic solvent, and the organic solvent includes an N,N,N′,N′-tetra(hydrocarbyl)urea.

Provided therefore herein is a novel acidic fluoride activated cleaning chemistry. The present invention includes novel acidic fluoride activated, unique organic-solvent based microelectronic selective etchant/cleaner compositions with high metal nitride etch and broad excellent compatibility, including tungsten (W) and low-k. It does not use W-incompatible oxidizers, such as hydrogen peroxide or particle-generating corrosion inhibitors.

The invention is a system and method for transforming food waste into a commercial cleaning product. The system is containable in an enclosed facility and installable in urban environments. Food waste is sorted and ground into uniformly sized particles, heated to an acceleration temperature, inoculated with an inoculant including lactic acid bacteria, which is mixed into the ground waste. The waste then undergoes sedentary fermentation for times as short as 24 hours or less. The fermented waste is separated into liquids and solids, and liquids are further separated into at least one distillation stream. Solids are dried to obtain a second distillation stream.

A method is provided for removing a residue from a surface. The method includes steps of applying a cleaning medium to the surface containing the residue. The cleaning medium comprises up to 100 wt. % of at least a solvent. Allowing the cleaning medium to be in contact with the residue for at least 5 seconds to swell/dissolve the residue for removing the residue from the surface. At least 50 wt. % of the residue and the cleaning medium are removed from the surface by wiping the surface with a shear force. The residue contains a sulfonated polymer having an ion exchange capacity (IEC) of greater than 0.5 meq/g. The sulfonated polymer can kill >90% of microbes coming in contact with the sulfonated polymer in less than 30 min.

The present invention relates to compositions such as cleaning compositions comprising enzymes. The invention further relates, use of compositions comprising such enzymes in cleaning processes.

The present invention relates to a method for the corrosion-protective and cleaning pretreatment of metallic components, produced at least partially from metallic materials from the elements iron, zinc and/or aluminum, with the use of an acid aqueous composition containing, in addition to the water-soluble compounds of the elements Zr and/or Ti causing the conversion of the metal surface, a mixture of an aliphatic diol and an aliphatic saturated polyhydroxy compound. It also comprises a chrome(VI)-free aqueous composition based on the constituents mentioned above which delivers outstanding results in cleaning and simultaneous corrosion-protective conversion of technical metal surfaces in one method step.
