Transparent neutral laundry detergent containing high-concentration chelating agent and preparation method thereof

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 [0001] The invention belongs to the field of detergent compositions, in particular to a transparent neutral laundry detergent containing a high-concentration chelating agent and a preparation method thereof. Background technique [0002] Laundry liquid has become a necessity in daily life. Laundry liquid products have the advantages of low temperature washing, easy dissolution, easy rinsing, energy saving, and consumption reduction. Most areas in my country are hard water, which contains various metal ions, among which hard water ions such as magnesium and calcium are the most harmful to the cleaning effect of surfactants, and the detergency of various surfactants in hard water is obviously reduced. One of the main problems of laundry detergent is that it is difficult to add various organic and inorganic anti-hard water additives. Generally, it is unstable if it is greater than 5%, so the detergency is slightly poor. In order to ensure detergency, more surfac...

AI Technical Summary

Problems solved by technology

One of the main problems of laundry detergent is that it is difficult to add various organic and inorganic anti-hard water additives. Generally, it will be unstable if it is greater than 5%, so the detergency is slightly poor. In order to ensure detergency, more surfaces must be added to the product. Active agents consume a lot of resources and cost. On the other hand, in order to increase the detergency, ordinary laundry detergents often add alkaline ingredients, which will cause certain damage to clothes, skin, and the environment.
