Problems solved by technology

However, due to excessive heating and light during the preparation and storage of amino acid soap, the triethanolamine salt turns yellow due to ultraviolet radiation and oxidation. The prior art mainly prevents amino acid soap from discoloration by adding sodium sulfite or sodium metabisulfite as an antioxidant, but the effect is not ideal. Amino acid soap will still gradually change color as the storage time prolongs, and sodium nitrite and sodium metabisulfite are more irritating to the skin, which greatly destroys the mildness of amino acid soap, and long-term use will have adverse effects on human health.

Abstract

The invention provides an amino acid soap. The amino acid soap is prepared from, by weight, 0.002-0.2 part of benzene azole sulfonate derivatives, 0.002-0.2 part of tri(tetramethyl hydroxyperidiol)citrate, 30-60 parts of N-acylamino acid, 15-30 parts of arginine, 3-10 parts of triethanolamine, 2-20 parts of strong base, 10-30 parts of moisturizing agent and 0.2-10 parts of skin modifier. The N-acylamino acid is selected from one or more of lauroyl glutamate, coconut oil acyl glutamate, tetradecanoyl glutamate, stearoyl glutamate, palmitoyl glutamate and cocamidopropyl propionic acid. According to the amino acid soap, the specific benzene azole sulfonate derivatives and tri(tetramethyl hydroxyperidiol)citrate are selected and added in the amino acid soap and have synergetic effects, so that the amino acid soap can more effectively resist discoloration caused by ultraviolet radiation, oxidation and other factors.

Description

Technical field [0001] The invention relates to the technical field of daily necessities, in particular to a stable amino acid soap and a preparation method thereof. Background technique [0002] Soap is a commonly used washing product in people's daily life. It has the advantages of convenient carrying, durability and environmental protection. Traditional soaps use fatty acid salts as the soap base. Soaps made on the basis of this soap base are extremely alkaline, with a pH of generally above 9. According to the traditional Chinese habits, they like soap to bring rinse But the strong alkaline soap usually makes people feel a strong sense of tightness after drying. Moreover, this kind of soap in hard water will form a precipitate with calcium, magnesium, and salt in the water, thereby losing its Washing capacity. [0003] Amino acid soap is a new type of facial soap that has emerged in recent years. Its biggest feature is that it uses amino acid surfactants instead of fatty acid ...
