摘要:
An environmental safety paint stripping composition comprising dichloroethylene, aromatic alcohols and ethers, surfactants, corrosion inhibitors, thickeners, wax solvents and water. This paint stripping composition is particularly useful in stripping paint and other polymeric coatings from metal substrates such as aluminum and it alloys.
摘要:
A liquid antibacterial soap comprising trichlorocarbanilide, wherein the composition includes, 0.1-5 wt. % trichlorocarbanilide, 0-40 wt. % water, 0.1-40 wt. % of a surfactant or mixture of surfactants, 10-60 wt. % of lower glycols to render the composition visually clear and stable, and 0.1-10 wt. % of a mixture of additional adjuvant ingredients.
摘要:
A cleaning system that utilizes an organic cleaning solvent and pressurized fluid solvent is disclosed. The system has no conventional evaporative hot air drying cycle. Instead, the system utilizes the solubility of the organic solvent in pressurized fluid solvent as well as the physical properties of pressurized fluid solvent. After an organic solvent cleaning cycle, the solvent is extracted from the textiles at high speed in a rotating drum in the same way conventional solvents are extracted from textiles in conventional evaporative hot air dry cleaning machines. Instead of proceeding to a conventional drying cycle, the extracted textiles are then immersed in pressurized fluid solvent to extract the residual organic solvent from the textiles. This is possible because the organic solvent is soluble in pressurized fluid solvent. After the textiles are immersed in pressurized fluid solvent, pressurized fluid solvent is pumped from the drum. Finally, the drum is de-pressurized to atmospheric pressure to evaporate any remaining pressurized fluid solvent, yielding clean, solvent free textiles. The organic solvent is preferably selected from terpenes, halohydrocarbons, certain glycol ethers, polyols, ethers, esters of glycol ethers, esters of fatty acids and other long chain carboxylic acids, fatty alcohols and other long-chain alcohols, short-chain alcohols, polar aprotic solvents, siloxanes, hydrofluoroethers, dibasic esters, and aliphatic hydrocarbons solvents or similar solvents or mixtures of such solvents and the pressurized fluid solvent is preferably densified carbon dioxide.

摘要:
This invention relates to compositions for removing biofilms from contaminated surfaces. The compositions minimally comprise a detergent and a salt or a salt-forming acid. Preferably, the compositions comprise a detergent and a salt-forming acid, to provide salts and acids in equilibrium, in such a way that the biofilm is rapidly dismantled and removed in such an environment. The compositions may also comprise a bactericide, for destroying bacteria.
