Correction fluid

It is typically packaged in small bottles, with lids attached to brushes (or triangular pieces of foam) that dip into the fluid.

Before the invention of word processors, correction fluid greatly facilitated the production of typewritten documents.

One of the first forms of correction fluid was invented in 1956 by American secretary Bette Nesmith Graham, founder of Liquid Paper.

Later, it contained 1,1,1-trichloroethane, a skin irritant now widely banned under the Montreal Protocol on Substances That Deplete the Ozone Layer, and then the slightly safer trichloroethylene.

Therefore, some manufacturers also sell bottles of solvent as "thinner", a few drops of which will return the correction fluid to its original liquid state.

This process consists of 3 methods: firstly, compounding the batch; secondly, quality control check; and thirdly, filling and packing.

Such solvents are common inhalants for adolescents[4] due, in part, to the fact that they are inexpensive in comparison to other recreational drugs.

[5] Companies have worked closely with authorities in order to ensure that all the warnings are duly mentioned on packaging (card and product labels) to inform parents and younger users of the risks associated with inhaling or drinking the fluid.

India has imposed a ban on the retail sale of bottled nail polish remover and bottled correction fluid, but permits its sale in devices that provide a small amount of the chemical in a container that dispenses it in a controlled way.

Correction fluid can be written on after it has dried.
