China Manufacturer N N-DIMETHYLAMINOACETIC ACID SODIUM SALT CAS 18319-88-5

1.  Description

 Chemical properties: N N-DIMETHYLAMINOACETIC ACID SODIUM SALT belongs to the sodium salt of amino acid derivatives. Its molecular structure is a salt formed by replacing the α - amino group of glycine with two methyl groups and reacting with sodium ions. The core functional groups are sodium carboxylate (- COONa) and tertiary amino (- N (CH3) ₂). The chemical properties are stable and not easily decomposed in neutral to alkaline environments. It has good high temperature resistance and avoids the problems of volatile free N, N-dimethylglycine and instability under acidic conditions. It also has a certain buffering capacity.
        Physical properties: N N-DIMETHYLAMINOACETIC ACID SODIUM SALT is a white crystalline powder or particle at room temperature, odorless or with a slight special odor. It has excellent water solubility and can quickly dissolve in aqueous systems such as pure water and physiological saline, as well as polar organic solvents such as methanol and ethanol. It is insoluble in non-polar solvents such as ether and petroleum ether. Its aqueous solution is weakly alkaline, with a pH value of about 8-10, and has good compatibility with most vitamins, surfactants, and food additives.
       Source and Preparation: N N-DIMETHYLAMINOACETIC ACID SODIUM SALT is naturally present in small amounts in plant and animal tissues such as beetroot, spinach, and animal liver. In industry, it is mainly prepared by chemical synthesis, using sodium chloroacetate and dimethylamine as raw materials, which are then aminated under alkaline conditions to produce high-purity products through crystallization, drying, and purification. The production process requires controlling the reaction temperature and the amount of dimethylamine used to ensure product purity and yield.

2.  Application

       In the field of dietary supplements, N N-DIMETHYLAMINOACETIC ACID SODIUM SALT is used as a dietary supplement raw material for the development of capsules, tablets, powders, and other dosage forms, targeting people who are concerned about exercise performance, immune health, and metabolic support. It is believed to participate in one carbon metabolism in the body, provide methyl donors for the body, adapt to sports nutrition, daily health care and other scenarios, and is one of the common dietary supplements in the European and American markets.
        Cosmetics: N N-DIMETHYLAMINOACETIC ACID SODIUM SALT is widely used in skin care products (such as face cream, lotion, essence) and shampoo products (such as shampoo, body wash) with its good moisturizing property, pH adjustment ability and mildness. It can be used as a moisturizer to improve dry skin conditions, as a pH regulator to stabilize the product system, and has low skin irritation, suitable for various skin types such as sensitive and dry skin.
        Industrial field: N N-DIMETHYLAMINOACETIC ACID SODIUM SALT is used as a surfactant, chelating agent, and intermediate in industries such as metal processing, detergents, coatings, etc. Can be used as a corrosion inhibitor in metalworking fluids to protect metal surfaces; Enhance the decontamination ability and foam stability in detergent; As a co solvent in coatings to improve coating fluidity and adhesion, it can also be used to synthesize other fine chemical products.

3. Main Efficacy

Metabolic support and methyl donor efficacy: N N-DIMETHYLAMINOACETIC ACID SODIUM SALT, as the active form of N, N-dimethylglycine, can participate in the one carbon metabolic cycle after entering the body, providing methyl groups to the body by converting into substances such as creatine and choline. Methyl is an important raw material for DNA methylation, protein modification, and neurotransmitter synthesis, which helps maintain normal cellular metabolic function and can assist in improving energy metabolism efficiency in exercise nutrition.
      Moisturizing and conditioning effects on the skin: The sodium carboxylate group in the N-DIMETHYLAMINOACETIC ACID SODIUM SALT molecule has strong hydrophilicity and can form hydrogen bonds with water molecules, forming a moisturizing film on the skin surface and reducing water loss; At the same time, its weak alkalinity can adjust the pH value of the cosmetic system, maintain a normal acid-base environment on the skin surface, enhance the skin barrier function, improve skin dryness, roughness and other problems, and keep the skin moist and delicate.
      Industrial functional efficacy: N N-DIMETHYLAMINOACETIC ACID SODIUM SALT has surface activity due to its tertiary amino group in industrial applications, which can reduce liquid surface tension and enhance the emulsifying and cleaning ability of detergents; Sodium carboxylate groups can form stable chelates with metal ions, playing a role in corrosion inhibition and rust prevention in metal processing; As an intermediate, the active groups in its molecular structure can participate in subsequent chemical reactions to synthesize derivatives with specific functions.
