Nitrocellulose has been used in a variety of applications, including as a key ingredient in nail polish, wood lacquers, and film coatings for pharmaceutical tablets. It is highly flammable compound and must be handled with care. If you’re curious about nitrocellulose and want to know more about its properties, applications, and considerations, keep reading!
1. What is Nitrocellulose?
Nitrocellulose is a highly flammable compound made by treating cellulose with a mixture of sulphuric acid and nitric acid. When treated with these acids, the cellulose fibers break down into short, fluffy fibers known as cellulose nitrate. This compound is then dissolved in a mixture of volatile solvents, creating a highly flammable liquid which can be used for a variety of applications.
2. Applications of Nitrocellulose
Nitrocellulose is used in various industries including cosmetic, pharmaceutical and automotive. In the cosmetic industry, nitrocellulose is used extensively as a primary ingredient for nail polish. Nitrocellulose is used in several grades known as RS grades, as a binder for printing inks or to add gloss and color to hair lacquers and cellulite creams. Automotive industries, on the other hand, use nitrocellulose as the base ingredient for car paints. Additionally, nitrocellulose is also used in the film coating of the extended release of the immediate release tablets.
3. Safety Considerations
Handling nitrocellulose requires careful precautions to avoid accidents. Due to the high volatility and flammability of this compound, it should only be used under specific consideration and in limited quantities. It is important to store nitrocellulose in cool, dry areas away from potential sources of heat and sparks. Also, protective equipment such as goggles, a respirator, gloves, and aprons should be worn when handling this compound.
4. How to Dispose of Nitrocellulose
Nitrocellulose should be disposed of carefully, using well-established procedures. The first step in disposing of nitrocellulose is to isolate it in a cool, dry location to avoid heat, friction, or sparks that can trigger combustion. It should be placed in ash or vermiculite in case of a fire and must not be disposed of by burning. If nitrocellulose is dissolved in solvents, it should be disposed of according to local and national regulations.
In conclusion, nitrocellulose is a widely used chemical, with applications in various industries such as cosmetics, pharmaceuticals, and automotive. It is important to keep in mind the safety considerations when handling, storing, and disposing of this highly flammable compound. Following well-established procedures and protective equipment can help prevent accidents and minimize the risk of ignition. Overall, nitrocellulose is a versatile and useful compound whose benefits are worth exploring.
