Abstract
The invention provides a transparent neutral laundry detergent containing a high-concentration chelating agent and a preparation method thereof. The laundry detergent contains sodium fatty alcohol-polyoxyethyleneether sulfate (70 percent), alpha olefin sulfonate, nitric acid, sodium hydroxide, polyacrylate, 2-hydroxypropionic acid, a fluorescent whitening agent, isothiazolinone, essence, and deionized water; and the laundry detergent contains the high-concentration chelating agent, solves the problem that the adding amount of a chelating agent is limited in a laundry liquid due to reasons such as solubility and the like, and ensures that the laundry detergent has the characteristics of strong hard water-resistant ability, strong detergency, easy rinsing and the like under the condition of lower content of a surfactant. The laundry detergent adopts natural and renewable raw materials, can be completely biodegraded, is neutral, has no phosphorus, protects skin, clothes and the environment, and solves the problems of poor hard water resistance, poor detergency, large resource consumption, large using amount, and high cost of common laundry liquids.
Description
Technical field
The invention belongs to the detergent composition field, specifically a kind of transparent neutral laundry detergent that contains high-concentration chelating agent and preparation method thereof.
Background technology
Washing liquid has become the requisite in the daily life, and the washing liquid product has advantages such as cold washing, easily dissolving, easily rinsing, energy-conservation, consumption reduction.The most of area of China all is a hard water, contains each metal ion species, and wherein maximum to the cleaning function harm of tensio-active agent with hard water ions such as magnesium, calcium, the detersive power of kinds of surface promoting agent in hard water all obviously descends.And one of subject matter of washing liquid to be various organic and inorganic anti hard water auxiliary agents be difficult to add, generally just unstable greater than 5%, therefore detersive power is poor slightly, in order to guarantee detersive power, must add more multilist surface-active agent in product, resource cost is big, the cost height, on the other hand, in order to increase detersive power, common washing liquid often adds alkaline components, and clothing, skin, environment are all had certain infringement.
An amount of washing assistant that sequestering action is arranged that adds in detergent formulation, both can reduce water hardness, again can be the metallic cation chelating that serves as a connection between original electronegative material such as fiber and electronegative dirt particle, the stable complex salt that forms solubility to be destroying the static combination between the dirt on the substrate matter, thereby makes dirt be easy to dissociate, disperse and be removed.Reasonable compatibility sequestrant and tensio-active agent, performance synergy did not both cause damage to fiber and cleaning of objects, did not have corrodibility, and it is good to have biological degradability again, does not make the water quality eutrophication, to advantages such as people, animal and waterplant are all nontoxic.So, need a kind of laundry detergent that contains high-concentration chelating agent in people's life.
Summary of the invention
The purpose of this invention is to provide a kind of transparent neutral laundry detergent that contains high-concentration chelating agent and preparation method thereof, contain polyoxyethylenated alcohol sodium sulfate (70%), α-Xi Jihuangsuanyan, citric acid, sodium hydroxide, polyacrylate, 2 hydroxy propanoic acid, white dyes, isothiazolinone, essence, deionized water among the present invention; The present invention contains high-concentration chelating agent, solved the problem that has limited the addition in washing liquid of sequestrant owing to reasons such as solvabilities, make this laundry detergent under situation, have strong, the strong detergency of resistance to hard water, easily characteristics such as rinsing than low surfactant content.
