Solution for removing various types of deposits from a surface

The invention relates to the field of removing various types of deposits from a surface, specifically to means for cleaning metallic and ceramic surfaces of industrial equipment, and can be used for removing deposits, such as oxides of metals (iron, chromium, nickel, etc.), carbonate and salt deposits, asphaltene-resin-paraffin deposits and deposits of a petroleum nature, and deposits of an organic and biological deposits. The proposed solution for removing various types of deposits contains hydrogen peroxide, complexone, an anti-foaming agent, water-soluble calixarene and water in the following ratio: hydrogen peroxide, a catalyst for decomposing peroxide compounds, an antifoaming agent, complexone, water-soluble calixarene and water in the following quantitative ratio:2-35% by mass of hydrogen peroxide; 2-20% by mass of a catalyst for decomposing peroxide compounds; 3-10% by mass of complexone; 0.1-5% by mass of surface-active agent; 0.01%-1.0% by mass of anti-foaming agent; 0.01-1% by mass of water-soluble calixarene, with the remainder being water. The technical result is an increase in the effectiveness of action of a solution (degree of cleaning) for cleaning surfaces soiled with deposits having a high content of organic substances, while simultaneously extending the field of use of said solution.

STABLE ACTIVATED PEROXIDE SANITIZING LIQUID COMPOSITIONS WITHOUT ADDED PHOSPHOROUS COMPOUNDS OR CATIONIC SURFACTANTS

Peroxide treatment compositions for use in laundry capable of providing sanitization through the wash e.g., for use with a detergent, where a peroxide activator is stabilized without the presence of phosphorus-containing compounds (e.g., phosphorus-containing stabilizers), through use of a nonionic surfactant (e.g., alkoxylated alcohol) with a cloud point above 45° C. Use of a single nonionic surfactant, or a surfactant package that may include a small fraction (e.g., less than 0.5%) of sodium lauryl sulfate or another anionic surfactant has been found to be surprisingly effective at stabilizing the peroxide/activator combination, even where water content may be 85% or greater. The composition can have a pH of 5 or less (e.g., 3 to 4). The composition may be free of other anionic surfactants, cationic surfactants, zwitterionic surfactants, amphoteric surfactants, magnesium salts, borates and boric acid, hydroxides, chelating agents, various amine oxides, ethoxylated amines, and the like.
