Oxygen-increasing phosphorus-free concentrated washing liquid and preparation method thereof

Abstract

The oxygen-increasing phosphorus-free concentrated washing liquid is prepared from the following raw materials in parts by weight: 5 to 7.5 parts of sodium percarbonate, 3 to 5 parts of potassium carbonate, 2 to 8 parts of citric acid monohydrate, 30 to 37 parts of active matters, 0.2 to 0.3 part of odor removing agent and 0.1 to 0.2 part of antioxidant, the active matter is prepared from the following components in parts by weight: 10-12 parts of fatty alcohol-polyoxyethylene ether sodium sulfate, 15-17 parts of sodium n-alkyl benzene sulfonate, 3-5 parts of lauryl sodium sulfate, 2-3 parts of cocamidopropyl and the balance of water, the production speed is high, the cleaning effect is good, and hands are not hurt.

Description

technical field [0001] The invention relates to the technical field of detergents, in particular to an oxygenated phosphorus-free concentrated washing liquid and a preparation method thereof. Background technique [0002] Sodium percarbonate (referred to as sodium percarbonate or SPC) is a compound of soda ash and hydrogen peroxide, which decomposes to produce oxygen, water and sodium carbonate. Sodium percarbonate is very suitable as a bleaching aid to be added to detergents. It can quickly decompose and release active oxygen at room temperature, so as to achieve the functions of decontamination, bleaching, disinfection and sterilization. Even if the washed fabric is dried in the shade, it will not produce odor. [0003] Since sodium percarbonate has high-efficiency washing ability, the oxygen-containing detergent added with sodium percarbonate can greatly improve the effective ingredients of the detergent, and can effectively remove fruit stains, wine stains, yellow scale...

AI Technical Summary

Problems solved by technology

Therefore, sodium percarbonate is a kind of high-efficiency, energy-saving, environment-friendly oxygen series bleaching auxiliary agent, accords with the development trend of modern detergent, has been widely used in washing industry, but existing sodium percarbonate is mostly used in solid detergent, This is due to the fact that sodium percarbonate dissolves very slowly in water and is difficult to add to liquid detergents. Carbonates also have strong cleaning capabilities. Like sodium percarbonate, the dissolution rate is slow and cannot be adapted to industrial applications. Rapid production, and the hydrogen peroxide generated by dissolving sodium percarbonate in water is corrosive, and consumers will inevitably hurt their hands when using it
