Problems solved by technology

In recent years, laundry detergent has been favored by consumers for its advantages of easy use, easy dissolution, and mildness to clothes and skin, and its market share has continued to grow. However, the water consumption of ordinary laundry detergents currently on the market accounts for about 70% of them. A large number of packaging materials have strict requirements on transportation conditions, resulting in an increase in product costs, transportation costs and carbon emissions, and quality problems such as leakage and pollution are prone to occur during the transshipment process
[0004] The process of concentrating domestic fabric detergents is relatively slow, and the reasons are as follows: On the one hand, the main production process of concentrated laundry detergent is agglomeration molding, and the products are mostly solid particles. Slow speed and poor solubility; on the other hand, concentrated laundry detergent may be affected by factors such as raw material selection, formula structure and production process, resulting in unstable product quality

Abstract

The invention relates to water-free laundry detergent. The appearance of the water-free laundry detergent is powder, and the powder is mixed with water to obtain traditional laundry detergent. The water-free laundry detergent is prepared from the following components in parts by weight: 60-90 parts of anionic surfactants, 3-10 parts of nonionic surfactants, 10-30 parts of auxiliaries, 0.1-0.5 part of liquid complex enzyme and 0.1-0.5 part of essence. The powder is mixed with water to obtain the laundry detergent, pH is neutral and mild, the dissolution is quickly and completely carried out, dissolved liquid is limpid and transparent, and the washed fabric is soft and free of residues; and therefore, the laundry detergent has all advantages of the traditional detergent; meanwhile, the laundry detergent is saving in packaging materials, low in production and transportation cost, and convenient and easy to carry.

Description

technical field [0001] The invention belongs to the field of daily chemical industry, and in particular relates to a production formula and production process of an anhydrous laundry detergent. Background technique [0002] Looking at the changes in the product structure of global cleaning products in recent years, the concentration, liquefaction and sustainable development of products are the main directions for future development. The United States began to concentrate laundry detergent in the 1980s. In the 1990s, laundry detergents began to develop in the direction of liquefaction. In 2003, laundry detergent was concentrated. Japan began to concentrate washing powder in the 1970s. So far, almost all of the market is concentrated washing powder. Laundry liquid also began to promote concentration in the 1990s. Highly concentrated liquid products began to appear in 2009. Japan’s Kao name The laundry detergent of ATACK NEO has a surfactant content of 74%, and the laundry det...
