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 kind of washing article commonly used in people's daily life, has advantages such as easy to carry, durable in use, environmental protection. Traditional soaps use fatty acid salt as the soap base. The soap made on the basis of this soap base is extremely alkaline, and the pH value is generally above 9. According to the traditional habits of the Chinese, they like to use soap to rinse Sometimes astringent feeling, but strong alkaline soap usually makes people feel a strong sense of tension after drying, and this type of soap will form precipitation with calcium, magnesium, salt, etc. in hard water, thus losing its washing power. [0003] Amino acid soap is a new type of face soap that has emerged in recent years. Its biggest feature is to use amino acid surfactants inste...
