Nitrogen Use in Aerosols

Nitrogen Use in Aerosols

                   

Introduction

An aerosol is any such substance enclosed under pressure and released as a fine spray by the means of a propellant gas. Common examples of aerosol products include deodorant sprays, pesticide sprays, hair sprays, shaving foams and the like.

Components of an Aerosol

An aerosol formulation mainly consists of two components, namely: (1 the product concentrate, and 2) the propellant.
The product concentrate is the actual product, the active ingredient in the aerosol, combined with other additional ingredients and co-solvents which are there to make a stable and efficacious product. The product concentrate can be a solution, suspension, emulsion, semisolid or powder.

The propellant is the gas which provides the force to expel the product concentrate from the container and is also responsible for the delivery of the formulation in the proper form (i.e. spray, semi-solid or foam).

Nitrogen as an Aerosol Propellant


Nitrogen is often used as an aerosol propellant for products that are dispersed as fine mists, foams or semisolids. Usually used in products where the sprays have to be fairly wet, nitrogen is a good choice for aerosols such as deodorants, perfumes, and shaving-foams, because it is insoluble, and this emits the product concentrate in the same form as it was placed in the container. Many aerosol manufacturers have nitrogen plants or nitrogen generators in their facilities, although CFCs (Chlorofluorocarbons) and HCFCs (Hydro Chloro Fluoro Carbons) are also used. However, the usage of these is now discouraged, as they harm the environment (mainly the ozone layer). Thus, nitrogen as a propellant is making a comeback in many popular aerosol products.


There are leading nitrogen gas plant manufacturers in India which you can contact if you feel the need of having a nitrogen generator or nitrogen plant installed on your premises. These manufacturers also offer mobile nitrogen plants, which are portable and thus efficient.

Nitrogen Application in Nylon Manufacture

Image
Nitrogen Application in Nylon Manufacture Introduction Nylon is actually a family of synthetic polymers, which can be processed into fibers, films or shapes. It is because of this thermoplastic’s silky property that made it the world’s first commercially successful synthetic thermoplastic polymer. Major uses of nylon include, but are not limited to fabrics, cookware and plastic fasteners and machine parts. Out of these, their application in manufacturing fabrics is the largest. Nylon fibers are woven together to form a silky, lightweight fabric. The reason for the popularity of this fabric is that it is resistant to abrasion, is a quite strong synthetic fiber, resists mildew, available readily and is relatively cheap. Application of Nitrogen in Nylon Manufacture Large-scale nylon manufacturers usually have nitrogen generators or nitrogen plants available on their premises, as nitrogen is an integral part of the production of various types of nylon. Nylon is form...

Application of Oxygen in the Manufacture of Epoxyethane (Engine Coolant/Antifreeze)

Application of Oxygen in the Manufacture of Epoxyethane (Engine Coolant/Antifreeze)                       Introduction Epoxyethane or ethylene oxide (C ₂ H ₄ O), is a colorless gas at room temperature. It is very reactive and is used as an important intermediary in the manufacture of many useful chemicals. But the main usage or application of Epoxyethane is as the main constituent of engine coolants or antifreeze in cars. It is also used to produce other engine coolants/antifreeze like ethylene glycol. What Does An Engine Coolant/Antifreeze Do? Car engines create a great deal of energy by burning petrol or diesel. Some of this energy is used to move the vehicle forward (around one third), the other two-thirds of the energy produced is converted to heat. Around half of this heat goes out of the exhaust, whilst the remaining heat remains inside the engine block. Car engines need a way of cooling down else t...
