Abstract

The invention relates to a preparation process of a neutral and dense oxygen-containing detergent composition. The specific steps are: 1) adding the composition of an acidic anionic surfactant, alkali metal hydroxide and water into a reactor for stirring and reacting; Add α-aminodicarboxylic acid or its alkali metal salt to the above reaction solution to continue the reaction; 3) add hydrogen peroxide aqueous solution to the reactor, and control the reaction temperature in the reactor to be 20-60°C; 4) use a mixing 5) Use a mixer to agglomerate the mixture formed by the system; 6) Dry and cool the granular detergent at least to obtain a neutral and dense oxygen-containing detergent combination. Beneficial effects: the granular detergent composition prepared by the method is an oxygen-containing detergent with excellent solubility, uniform distribution, variable active oxygen content, stable performance and excellent washing effect.

Description

technical field [0001] The invention relates to a preparation process of a neutral dense oxygen-containing detergent composition. Background technique [0002] Many prior art attempts in this direction suffer from low solubility problems due to slow dissolution rates or gel formation. The result is that it is difficult to feed product from the washing machine ingredient drawer or from a feeder fitted to the laundry tub in the machine during a typical wash. This poor partitioning is generally caused by the gelation of particles with high surfactant content on contact with water. This gel prevents a portion of the washing powder from dissolving in the wash water, reducing the efficacy of the powder. Even though the powder is easy to dispense and disperse in the wash water, it can have the opposite effect if it does not dissolve quickly. A wash cycle has a defined duration during which detergent can act on the laundry. If the cleaning action is prolonged due to the slow dis...
