| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| amine oxide | amine oxide is the product of tertiary amine oxidized with hydrogen peroxide or peroxyacid. this kind of compound was studied as early as 1900, and the patent of dodecyl dimethyl amine oxide was published in 1939. In the 60s, its application in detergent formulations was discovered. In aqueous solution, amine oxide can show non-ionic (neutral or alkaline conditions) or cationic (acidic conditions) depending on the pH value. Amine oxide has excellent foaming and stable foaming properties, and is the most effective thickener. It also has a conditioning effect. In addition, it has low toxicity and low irritation. It can be used for shampoos, baths and high-grade detergents. The most commonly used are dodecyl dimethyl amine oxide, trade names OA-12, decyl dimethyl amine oxide and amidopropyl amine oxide. |
| application | amine oxide is a non-toxic, mild, soft and moisturizing surfactant, thus arousing the interest of daily chemical industry and using it to prepare shampoo, bath soap and tableware detergent. Shampoo is an important application field of amine oxide, which can thicken the product, have good pearlescent effect and solubilize the spice. The shampoo prepared by amine oxide as a component can make hair smooth and smooth, and can reduce the irritation of some drugs. This is because amine oxide can directly interact with the hydroxyl groups on the hair and skin horn under certain pH conditions. Among them, the long-chain alkyl part of amine oxide can give softness, eliminate static electricity, easy to comb, and make the hair black and shiny. Although cationic surfactant can also combine with the upper hydroxyl group of hair and skin horn and play the role of combing, softening and reducing static electricity, it has strong irritation to eyes and skin, and long-term use will cause excessive hair and skin Degreasing, and it cannot be compatible with anionic surfactants with a large amount of shampoo. The preparation of liquid bath soap with amine oxide can improve the roughness of the skin, because amine oxide has excellent foaming and foaming stabilization effects. It is reported that in order to obtain considerable foam stabilization ability, the amount of amine oxide should be the 1/3 of alkanolamide. The foam produced by amine oxide is delicate and creamy, and has no irritation to eyes and skin. These properties are especially suitable for preparing baby bath soap. When it is used in the solution with AES, it has a synergistic effect, so that the comprehensive washing effect is significantly improved. |
| preparation method | 1. direct oxidation of air or oxygen to prepare amine oxide is prepared by oxidizing tertiary amine with oxidant. there are two synthesis processes. the reaction formula is as follows: R1R2R3N + O2 → R1R2R3N → O amine oxide products with a content of 30% to 80% can be prepared by passing oxygen or air into an autoclave with water, alcohol solvent and tertiary amine under the conditions of 100-150 ℃ and 15-70MPa for 16-64h. 2. using nitrogen peroxide or organic acid peroxide as oxidant to prepare the reaction formula is as follows: R1R2R3N + H2O2 → R1R2R3N → O tertiary amine is dissolved in water (or alcohol solvent), and a small amount of citric acid and disodium EDTA are added. When the temperature is raised to 60-70 ℃, 30% hydrogen peroxide is added dropwise to keep the temperature for lh, then the temperature is continued to be raised to 75-80 ℃ for 3h, the temperature is lowered to 60 ℃ and the calculated sodium bisulfite is added to decompose the residual oxygen, and the liquid product with 30% active substance can be obtained by discharging the material. The tertiary amine conversion rate can reach more than 98%. The addition of human citric acid as a hydrogen peroxide stabilizer, EDTA disodium as a metal ion mixture, the two also play a catalytic role to improve the tertiary amine conversion rate. |
