A method is provided for removing silver mirroring from the surface of a black-and-white negative film by: mixing 80-100 parts by mass of triethanolamine, 0-10 parts by mass of glycerol and 0-10 parts by mass of a surfactant uniformly under stirring to produce a silver mirroring remover, where the surfactant is one or more of isomeric tridecanol polyoxyethylene (8) ether, polyethylene glycol 200, polyethylene glycol 400 or alkylphenol polyoxyethylene (10) ether; applying the silver mirroring remover onto the region of the surface of the negative film, where the silver mirroring occurs, allowing the film to stand for at least 30 minutes, and then blotting up the residual solution on the negative film; and soaking the negative film in n-butanol and cleaning it, and then blotting the residual solvent on the negative film, followed by air drying, to complete the removal of silver mirroring on the surface of the negative film.

Cleaning solution for cleaning and/or wetting metal surfaces, comprising at least one acid, a first surfactant, which is an alkyl-poly(ethyleneglycol-co-propyleneglycol)-ether having a cloud point of ≤25° C., a second surfactant, which is selected from the group consisting of i) an alkyl-poly(ethyleneglycol-co-propyleneglycol)-ether having a cloud point of ≥30° C., ii) an alkyl-polyethyleneglycol-ether having a cloud point of ≥45° C.
wherein the cloud points are determined according to European Standard EN 1890:2006, item 8.2 of German Version, with the modification that 10 wt % H.sub.2SO.sub.4 is used as solvent and that the concentration of the surfactant is 1000 mg/L.

The present disclosure relates to cleaning compositions in general, and cleaning compositions that are well suited for use by individuals, who experience adverse health effects that may occur upon exposure to certain chemicals. This condition, characterized as multiple chemical sensitivities (MCS), makes it virtually impossible for certain individuals to use commercially available cleaning products without inducing immunological responses. The disclosure presents and describes protocols for the formulation and evaluation of a variety of cleaning products and dilutable cleaning product concentrates using a combination of .sup.14C assay, head space analysis and screening of both ingredients and final products for governmentally-regulated materials. The methods and compositions newly presented herein avoid causing adverse health responses in individuals and are suitable for use by any person, particularly individuals who experience MCS.

The present invention relates to a method for reducing hydrophobic soil from a textile comprising the step of treating the textile with a cleaning composition comprising at least two surfactants selected from nonionic surfactants of general formula (I) and/or alkylpolyglycosides of general formula (II). The present invention further relates to a use of the cleaning composition for reducing hydrophobic soil from a textile.

Compositions comprising a neutral surfactant or a reaction product thereof and a reaction product of a saccharide polymer and a fatty acid may be obtained in the presence of water and a hydroxide base (optionally in the presence of the neutral surfactant), the saccharide polymer comprising a dextran, a dextrin compound, or any combination thereof. The reaction product of the saccharide polymer and the fatty acid may be present at a concentration effective to lower surface tension of the neutral surfactant. Depending on the fatty acid identity, among other factors, the compositions may promote emulsification or de-emulsification. In addition, the compositions may promote foam formation under appropriate conditions. Treatment fluids comprising the compositions, including foamed treatment fluids, may be introduced into a subterranean formation to perform a treatment operation in which fluid emulsification or de-emulsification may occur. The reaction products may be incorporated in soaps and other personal care products.

A composition includes a C10 aliphatic branched chain alcohol ethoxylate; a C12 aliphatic straight chain alcohol ethoxylate, and a reactive builder. The composition effects an increase of at least about 30% in detergency measured as reflectance at 460 nanometers (nm) of a stained fabric at which the composition has been applied when compared to reflectance observed at 460 nm at the stained fabric prior to application of the composition. The stained fabric treated at which the composition has been applied exhibits a reflectance at 460 nm that is greater than the reflectance of the stained fabric at which a substantially similar composition has been applied. The substantially similar composition includes nonyl phenol ethoxylate.
