Toothpaste containing sodium N-dodecanoyl-L-alaninate as surfacant

Abstract

The invention discloses a toothpaste containing sodium N-dodecanoyl-L-alaninate as a surfacant, and relates to the field of daily chemical products. By adopting a sodium N-dodecanoyl-L-alaninate or potassium N-dodecanoyl-L-alaninate containing key technology, 30 to 50 parts by weight of sorbitol, 5 to 15 parts by weight of glycerol, 2 parts by weight of polyethylene glycol-400 and 10 parts by weight of water are put into a main boiler and are evenly mixed; 15 to 20 parts by weight of powder phase silicon dioxide, 0.1 to 1 part by weight of sodium carboxymethyl cellulose, and 0.1 to 0.3 part by weight of carrageenan are put into a powder mixing machine for being evenly mixed, and then are put into the main boiler to be evenly stirred; 1 to 3 parts by weight of sodium N-dodecanoyl-L-alaninate or potassium N-dodecanoyl-L-alaninate, 0.1 to 0.3 part by weight of saccharin sodium, 0.2 to 0.6 part by weight of sodium benzoate and 2.8 to 41.5 parts by weight of water are heated to 45 DEG C and then are dissolved and put into the main boiler; 0.2 to 1 part by weight of essence and 0.0001 to 0.1 part by weight of brilliant blue fluorescent are put into the main boiler; all materials in the main boiler are stirred and PH is regulated to 6 to 8, and the materials are vacuumized while the materials are stirred so as to prepare the toothpaste containing sodium N-dodecanoyl-L-alaninate or the potassium N-dodecanoyl-L-alaninate as the surfacant. The preparation of the toothpaste has a stable and reliable effect.

Description

technical field [0001] The toothpaste containing lauroylalanine sodium salt as a surfactant of the invention relates to the technical field of daily chemicals. Background technique [0002] In toothpaste, surfactants are needed, such as sodium dodecyl sulfate SDS. Although sodium dodecyl sulfate SDS has good cleaning and decontamination ability and is widely used in production and life, its biodegradability and ecological Compatibility is average, and has a certain degree of irritation. As people pay more and more attention to the safety, mildness and environmental protection requirements of various products, the research and development of multifunctional and high-quality environmentally friendly surfactants has become the main direction of the surfactant industry. [0003] Hydrolyzed oat protein contains a variety of amino acid components. Sodium cocoyl hydrolyzed oat protein is a surfactant based on biological substances. Because of the amino acid skeleton in the molecul...

AI Technical Summary

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 a 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, which are expensive and limit the development of related domestic daily chemical products.
