Specialists must consider the mixer and temperature control system carefully, and also the formula instructions, the correct types, and the amounts of raw materials at specified times by using computer controls. Stainless steel tanks are used to hold 3,000 US gallons (11,000 L 2,500 imp gal) or more. The manufacturer is required to affix a warning regarding the possible adverse effects on health if the material is inhaled. The Ministry of Education also banned its use in schools in 2017. 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. Ĭompanies 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. An unpleasant smell is added to some brands in order to deter abusers. Use of correction fluid as an inhalant can cause the heart to beat rapidly and irregularly, which can cause death. Such solvents are common inhalants for adolescents due, in part, to the fact that they are inexpensive in comparison to other recreational drugs. Organic solvents are psychoactive when sufficient amounts are inhaled. However, those have the disadvantages of a longer drying time, and incompatibility with some inks (which will soak through them). To avoid the inconveniences of organic solvents (safety and availability), some brands of fluid are water-based. 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. It can become too thick to use, and sometimes completely solidifies. Because it contains organic solvents ( volatile organic compounds), unused correction fluid thickens over time as volatile solvents escape into the air. Thinners currently used with correction fluid include bromopropane.

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. Thinner originally contained toluene, which was banned due to its toxicity.
The opacifying agent can be composed of a mixture of titanium dioxide, latex, and other polymer resins.
The exact composition of correction fluid varies between manufacturers, but most fluids are composed of an opacifying agent, a solvent (or thinner) and an adulterant 'fragrance' to discourage abuse. Correction fluid was applied on a glass base (visible in the bottom-right corner of all SEM images).
The micro-structural details of the copolymer resin are visible under high magnifications. Correction fluid copolymer visualized under scanning electron microscopy (SEM).
