Problems solved by technology

[0004] There are currently more than 200 kinds of amino acids, and only dozens of basic amino acids can be used to synthesize N-acyl amino acid surfactants. Now the amino acids and their salts are commonly used in the synthesis of N-lauroyl amino acid surfactants for cosmetics. Only sarcosine, glutamic acid, glycine, serine, lysine, leucine, etc. have reached their climax in their application and research since the 1970s. At present, this type of product has been widely used abroad, and the more influential ones are Products such as Hanposyl in the United States, Medialan in Germany, and Amisoft in Japan are not yet mature in production in my country, and the demand is still dependent on imports. The price is expensive, which limits the development of domestic laundry detergent, etc.

specific Embodiment approach 1

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings. As attached to the manual figure 1 Shown:

[0027] A laundry detergent containing lauroyl sarcosine sodium salt and sodium cocoamidopropionate, the preparation method of which is: adding 0.1-3 parts by weight of sodium carboxymethylcellulose and 0.1-1 parts by weight of polyvinylpyrrolidone 65-85 parts by weight of water are stirred and dissolved at 60-70°C, 0.1-5 parts by weight of laureth-9 is added to dissolve, and then 3-15 parts by weight of sodium lauroyl sarcosinate, cocamidopropyl beet 0.1-6 parts by weight of alkali, 3-15 parts by weight of sodium cocoamidopropionate, 0.1-4 parts by weight of C8-18 alkyl glucoside, 0.1-2 parts by weight of trisodium citrate, and cool to 45 Below ℃, use 0.1-2 parts by weight of citric acid to adjust the pH to 6-10, add 0.1-1 parts by weight of Cathone, 0.0001-0.1 parts by weight of brilliant blue, 0.1-3 parts by weight of pr...

specific Embodiment approach 2

[0033] Carry out according to specific embodiment 1, only: change the weight part of each constituent material into specific weight unit " gram " and carry out concrete implementation, also obtain expected good effect.

specific Embodiment approach 3

[0035] Carry out on the implementation basis of specific embodiment one, two, just: to the consumption of each composition material, respectively reduce 1,3,5,7,10 times respectively on the basis of original consumption and enlarge respectively 1,3,5, 7, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 80, 90, 100, 150, 200, 250, 300, 350, 400, 450, 500 times The implementation was carried out; all obtained the expected good results. Like this, the present invention just has the solid foundation of small-scale experiment, laboratory experiment, enlarged experiment, medium-scale experiment, productive experiment respectively, both has solid theoretical basic experiment, has operable productive experiment again, is convenient to popularize widely application.

Abstract

The invention discloses laundry detergent containing sodium lauroyl sarcosine salt and cocoamido sodium propionate and relates to the technical field of daily chemical products. With the key technology of containing of the sodium lauroyl sarcosine salt and the cocoamido sodium propionate, 0.1-3 parts by weight of sodium carboxymethylcellulose and 0.1-1 part by weight of polyvinylpyrrolidone are placed into 65-85 parts by weight of water to be stirred and dissolved at the temperature of 60-70 DEG C, 0.1-5 parts by weight of laureths-9 is added and dissolved, then 3-15 parts by weight of sodium lauroyl sarcosinate, 0.1-6 parts by weight of cocamidopropyl betaine, 3-15 parts by weight of cocoamido sodium propionate, 0.1-4 parts by weight of C8-18 alkyl glucoside and 0.1-2 parts by weight of trisodium citrate are added sequentially and are dissolved completely, then the temperature is decreased to 45 DEG C or below, pH is adjusted to 6-10 through citric acid, kathon, brilliant blue, propylene glycol and fragrance are added, and the laundry detergent is obtained through even stirring. The laundry detergent is used for washing clothes and is high in surface activity, environmentally friendly and stable and reliable in effect.

Description

technical field [0001] The laundry detergent containing sodium lauroyl sarcosine and sodium cocoamidopropionate of the present invention relates to daily chemical product technology field. Background technique [0002] As far as laundry detergent is concerned, everyone is familiar with it on the surface, but everyone does not understand its inner essence. In laundry detergent, surfactants, such as sodium dodecylbenzene sulfonate LAS, are used, although they have Good washing and decontamination ability is widely used in production and life, but it has the disadvantages, defects and disadvantages of poor biodegradability and ecological compatibility, which will cause harm to the environment. As people pay more and more attention to the safety, mildness and environmental protection requirements of various products, the research and development of multifunctional, high-quality and environmentally friendly surfactants has become the main direction of the surfactant industry. ....
