Embodiment 1

[0041] 55Wt.% Hydrogen peroxide 4Na 2 SO 4 . 2H 2 o 2 . NaCl, 5 Wt.% anhydrous sodium sulfate, 2 parts of zeolite (Zeolite NaA) and 38 Wt.% anhydrous citric acid were mixed, and the mixture was placed in an oven at 35-41°C to determine its stability. The hydrogen peroxide concentration of the product obtained was measured by iodine reduction titration. It can be observed that after the first day, because the hydrogen peroxide salt was not completely dried, the activity decreased by 17%, and decreased by 0.25% every day thereafter. The mixture has a great oxidizing ability and can oxidize KI dissolved in water into iodine.

Embodiment 2

[0043] 33 Wt.% hydrogen peroxide adduct 4Na 2 SO 4 . 2H 2 o 2 . NaCl, 26 Wt.% Sodium Sulfate, 2 Wt.% Zeolite (Zeolite NaA) and 2 Wt.% melted Plurafac SLF18 B45 were mixed and 37 Wt.% of anhydrous citric acid was added. Stability was determined by placing the mixture in an oven at 35-41°C. The hydrogen peroxide concentration of the product obtained was measured by iodine reduction titration. It can be observed that after the first day, because the hydrogen peroxide salt was not completely dried, it decreased by 10%, and the subsequent daily decrease hardly changed. The mixture has a great oxidizing ability, which can oxidize KI dissolved in water into iodine.

Embodiment 3-4

[0045] The following light-duty acid detergent powder is used to clean dishwashers and washing machines. Hydrogen peroxide adduct 4Na 2 SO 4 2H 2 o 2 · NaCl is coated with zeolite, and then melted Plurofac SLF18 B45 is added. The remaining components are added and mixed according to the following table sequence:

[0046]

[0047] The storage stability of light-duty acid cleaners is measured at 30-41°C. The activity of detergent powders for dishwashers and washing machines decreased by 0.1% and 0.2% per day, respectively, after more than four weeks of observation, showing a descaling capacity of 0.35 and 0.19 CaCO 3 / g detergent powder. The descaling ability is tested in an aqueous solution of one percent detergent powder. This result proves that this detergent powder has a good descaling ability. When tested by standard iodine reduction titration at room temperature, after 5 minutes of reaction without adding additional sulfuric acid, it can be titrated to 90% hydro...

Abstract

The invention discloses an acidic cleaning composition. The acidic cleaning composition is characterized in that the composition comprises the following components by weight percent: 10-90% of hydrogen peroxide adduct which is stable under the acidic condition, 10-90% of acidic material, 0-50% of anionic surfactant, 0-20% of nonionic surfactant, 0-10% of chelating reagent, 0-90% of additive, 0-40% of activator, 0-10% of corrosion inhibitor and 0-15% of other reagents. The acidic cleaning composition disclosed by the invention has multiple functions of bleaching, descaling, disinfecting, removing the biofilm and the like; and the composition is mainly used as the surface cleaning agent, and can be dispersed in water to wash the inside of the washing machine and the inside of the dish-washing machine or used to clean and disinfect the common hard surface, etc.

Description

technical field [0001] The present invention relates to a cleaning composition, and more specifically designs a cleaning composition that is stable under acidic conditions. Background technique [0002] At present, the household cleaners appearing in the market cannot effectively complete bleaching, disinfection, deodorization and descaling at the same time. Acidic compositions are commonly used to remove inorganic soils such as carbonates and soap scum. Such products contain inorganic acids such as hydrochloric acid, sulfamic acid or organic acids such as amino acids, lactic acid, citric acid, glycolic acid, etc. Patents such as US 7368417, US 7153817, US 6627590, US 6432395, US 5925606 and US 5523012 and patent application US 2011 / 0146707 etc. describe the application of these acids as inorganic descaling agents in hard surface cleaners. The inorganic descaling agents invented in patents US 6191091 and US 6699825 use organic quaternary ammonium salt bactericides, thereby...
