This versatile product finds applications in various sectors, including pharmaceuticals, personal care, textiles, and paper production. This article discusses the properties, applications, and safety considerations of DTAC.

Properties of DTAC

DTAC is a cationic surfactant that belongs to the quaternary ammonium salt family. It has a molecular weight of 263.90 g/mol and a white crystalline powder appearance. DTAC is soluble in water and ethanol but insoluble in benzene and chloroform. It has a melting point of 232-235°C and a boiling point of 100°C at 0.1 mmHg.

DTAC has excellent surface activity, emulsifying, and sterilizing properties. It is stable at a wide range of pH and temperature, making it suitable for various applications.

Applications of DTAC

DTAC has a wide range of applications in different industries, including:

1. Pharmaceuticals: DTAC is commonly used as a preservative and emulsifier in various pharmaceutical formulations. It is also used in the production of antiseptics, disinfectants, and other medical products.

2. Personal care: DTAC is found in many personal care products like shampoos, conditioners, and lotions. It functions as a surfactant, emulsifier, and antimicrobial agent.

3. Textiles: DTAC is used in the textile industry as a softener, antistatic agent, and emulsifier. It enhances the fabric's water repellency and durability.

4. Paper production: DTAC is used in the paper production process as a wetting agent, antistatic agent, and emulsifier. It improves the paper's surface tension and printability.

Safety Considerations

DTAC is generally considered safe for use in various applications. However, it is essential to follow safety precautions when handling this product. DTAC can cause skin and eye irritation, and inhalation of its dust can cause respiratory irritation. It is recommended to wear protective clothing, gloves, and goggles when working with DTAC.

DTAC should be stored in a cool, dry, and well-ventilated area away from heat and moisture. It should be kept away from incompatible materials like strong acids, bases, and oxidizing agents.

Conclusion

DTAC, also known as Surfactant 123, is a versatile cationic surfactant with excellent surface activity, emulsifying, and sterilizing properties. It finds applications in various industries, including pharmaceuticals, personal care, textiles, and paper production. INNO Specialty Chemicals is a leading manufacturer and supplier of DTAC in China. While DTAC is generally safe for use, it is essential to follow safety precautions when handling this product.
