N-Octadecyltrimethylammonium Chloride: Understanding Its Properties and Applications

In the world of chemistry, surfactants play a crucial role in many industrial applications, including food, pharmaceuticals, and cosmetics, to name a few. One such surfactant is N-octadecyltrimethylammonium chloride (OTAC), also known by other names such as Emulsifier 1831, Asphalt emulsifier, and Stearyl Trimethyl Ammonium Chloride. INNO SPECIALTY CHEMICALS, a leading manufacturer and supplier from China, produces this cationic surfactant that has a wide range of uses. In this article, we will delve deeper into the properties and applications of N-octadecyltrimethylammonium chloride.

Properties of N-Octadecyltrimethylammonium Chloride

N-octadecyltrimethylammonium chloride is a quaternary ammonium salt with the chemical formula C21H46ClN. The surfactant is a white powder or granular solid that is soluble in water and organic solvents like ethanol, isopropanol, and acetone. The compound is also hygroscopic, meaning it can absorb moisture from the atmosphere. OTAC has a melting point of 62-66°C and a boiling point of 100°C.

One of the distinguishing properties of N-octadecyltrimethylammonium chloride is its cationic nature, which makes it an effective emulsifying agent. The positively charged head of the surfactant attracts negatively charged particles like dirt, oil, and grease, allowing them to be dispersed in water. This property makes OTAC an excellent ingredient for cleaning products and detergents.

Applications of N-Octadecyltrimethylammonium Chloride

OTAC has a wide range of applications across several industries, thanks to its emulsifying, solubilizing, and disinfecting properties. Here are some of the common uses of N-octadecyltrimethylammonium chloride:

1. Asphalt Emulsifier

Asphalt emulsions are used in road construction to bind aggregates together. N-octadecyltrimethylammonium chloride is a key ingredient in the production of asphalt emulsions. OTAC helps to stabilize the emulsions by preventing the separation of asphalt from water.

2. Detergents and Cleaning Products

N-octadecyltrimethylammonium chloride is an effective cleaning agent due to its ability to emulsify oils and grease. The compound is commonly used in household cleaning products like laundry detergents, fabric softeners, and all-purpose cleaners.

3. Paper and Pulp Industry

OTAC is used in the paper and pulp industry as a flocculating agent. The surfactant helps to bind fine particles together, making them easier to remove during the paper-making process. The use of OTAC results in higher paper quality and reduced production costs.

4. Personal Care Products

N-octadecyltrimethylammonium chloride is also used in personal care products like shampoos, conditioners, and body washes. The surfactant provides conditioning and anti-static properties to hair and skin.

5. Disinfectants

OTAC has antimicrobial properties and is effective against a wide range of bacteria and viruses. The surfactant is commonly used in disinfectant products like surface cleaners, hand sanitizers, and wound care products.

Conclusion

N-octadecyltrimethylammonium chloride is a versatile surfactant with a wide range of applications across several industries. Its cationic nature makes it an effective emulsifying agent, while its ability to disinfect and solubilize makes it a valuable ingredient in many products. INNO SPECIALTY CHEMICALS is a manufacturer and supplier of high-quality N-octadecyltrimethylammonium chloride, and their product is widely used in different industries. With its unique properties, OTAC is a crucial component in many products that we use in our daily lives.
