  2.  Solvents can be defined as chemicals that are capable of dissolving, suspending, or extracting other substances, typically without causing changes in the chemical nature of either the solvent, or the materials being treated.
  3.  Industrial solvents are a chemical class that can be found in many different applications.  They are used to remove solids, grease, and other substances from materials. They have also been used as cleaning agents for many years. At the same time, they have also been known to cause harm to humans and the environment. 
  4.  Solvents can be both organic and nonorganic. When a solvent is organic, it contains carbon.
  5.  Halogens – fluorine, bromine, iodine- respiratory tract irritants  alkaline materials – ammonia, calcium hydroxide, calcium oxide, potassium hydroxide, sodium carbonate etc. – corrosive local action such as irritating to all mucous membranes; nitrous oxide is a weak narcotic  trace metals – cadmium, chromium, copper, lead, manganese, mercury, nickel, arsenic – toxic and environmentally perssistant
  6.  Organic solvents are classified by their chemical structure. There are three main types, including:  Hydrocarbon solvents-  Aliphatic and aromatic hydrocarbons.  Oxygenated solvents-  Alcohols, aldehydes, ketones, glycol ethers, esters, and glycol ether esters.  Halogenated solvents-  Chlorinated and brominated hydrocarbons.
  7.  Halogenated hydrocarbons - methylchloride, chloroform, carbon tetrachloride. Many of them are used in dry cleaning or solvents.  Alcohols – methanol, ethanol, propanol etc. – most notable toxic to the central nervous system.  Glycols and derivates – ethylene glycol are used as antifreezeing agents.
  8. An organic solvent and is an important industrial solvent because of its low volatility towards air, its ability to evaporate off when exposed to light, it is also very cheap and widely used as a solvents. It can be used as a solvent for many different applications such as. It terms of inertness, 1,2-Dichloroethane ( 1,2- DCE) is one of the few low-viscosity solvents that has been shown to be safe.
  9.  Colorless viscous liquid or powder, a new type of high-efficiency and low-toxicity detergent solubilizer conditioner. It is a powerful chemical which can be used to dissolve metal, ceramic and non-metallic materials through oxidation.  Sodium Xylenesulfonate is widely used in chemical industry because of its high efficiency, low toxicity and low cost. It can dissolve metal, ceramic and non-metal materials like stainless steel, ferrosilicon, brass materials etc., at room temperature or below the temperature
  10.  Inhalation -This is the easiest way in which solvents are harmful to you. Because they are absorbed by your lungs and then into your body, they can cause a number of respiratory problems such as asthma. The most common reason for inhalation is due to car exhaust fumes and any work that requires you to wear respirators.
  11.  Many industrial sol vents leave your skin dry and flaky, which can result in rashes, bumps and burns. So if you’re working with chemical solvents or paint thinner, you need to be cautious about how much of the solvent is applied on your skin.
  12.  Many industrial solvents can cause eye problems; this mostly happens when they evaporate on clothing or skin. If you’re using solvent for cleaning or painting, you need to be careful about how much solvent is applied on your clothes and skin as well. Make sure to wear gloves and protective eyewear if your exposure to the chemicals is high enough.
  13.  Many solvent are potentially toxic to the liver either alone or in combination With other solvent . For example liver damage is caused by the dry cleaning solvent carbon tetrachloride Other chlorinate and hydrocarbons.
  14.  Chronic drug and alcohol abuse can lead to severe kidney damage or failure. Like carbon tetrachloride trichloroethane .  Foe example gasoline , gel fuel , turpentine are among the most common toxicant.
  15.  Typical solvent applications include  Pharmaceuticals  Cosmetics  Agrochemicals  Paints and coatings  Cleaners and degreasers  Ink
  16.  Whether it be from penicillin to viagra, the manufacturers of large amounts of everyday pharmaceutical products would be impossible without the inclusion of solvents in the operations of producing them
  17. As mentioned previously, a lot of products that we see and use in our everyday lives are produced as a result of solvents. This would include cosmetic materials such as baby oil and face creams, nail polish, skin lotion, and other types of moisturizers.
  18.  For modern farming, crop protection is an integral part to emphasize given that it is required to produce the vast amount of foods required to help feed a population that continues to grow. Solvents are very useful for the production and application for both fertilizers and crop protection formulas.
  19.  When looking at paints or coatings, solvents tend to dissolve or disperse varying components of its formulation such as pigment and resin, allowing for the final product to have the desired consistency that is required. Once the paint has been applied, the solvents then evaporate, allowing for the resins and pigment to form a protective coat or film, and then eventually dry off.
  20.  When looking at the printing inks used by daily newspapers and magazines, even the labels and packing used for goods ordered off of amazon, and foods, in general, depend a lot on solvents in order for the texts and designs to be applied properly and to stay in place  Through controlling the viscosity within the ink formulations, the solvents can allow for just enough ink to flow in order for the print on the magazines/labels/newspapers to be just visible to just the right extent in order to be effective
  21.   If solvent-based products are used, make sure the work area is well ventilated.  Open doors, windows, roof lights, etc. To increase ventilation and make sure that  they are kept open. Local exhaust (mechanical) ventilation may be necessary in some cases.  If possible, avoid spraying solvent-based products, as this causes more vapour to get into the air than using a brush
