Molecular Structure of Ethylene glycol
Rating

Ethylene glycol is a clear, colorless, odorless, slightly syrupy liquid at room temperature, with a sweet to bittersweet taste. Ethylene glycol is used in hydraulic brake and radiator fluids, as well as in deicing solution. This substance increases the boiling point and decreases the freezing point of radiator fluid. When it is used as an automotive antifreeze, it is often mixed with a yellow-green fluorescent dyes and a bitter taste to reduce the chances of accidental ingestion. Ethylene glycol is also used as a solvent in the paint and plastics industries and in the formulation of printer's inks, stamp pad inks, and ball-point pen inks. Ethylene glycol is a monomer used in the synthesis of safety explosives, resins, plasticizers, elastomers, synthetic fibers and synthetic waxes. Vapors of ethylene glycol are nonirritating to the eyes and throat; liquid ethylene glycol is irritating to eyes and skin.

Molecular Structure of Salicylic acid
Rating

Salicylic acid is a colorless to white crystalline powder with a sweetish acrid taste that occurs naturally in many microorganisms and plants in very small amounts. It is also made synthetically and used as preservative of food products in some countries and as an antiseptic in mouthwashes and toothpastes. This chemical is also used in the manufacture of methyl salicylates, acetylasalicylic acid (aspirin) and other salicylates. Salicylic acid is a chemical intermediate in the synthesis of dyestuff, salicylate esters and salts. It is prepared commercially by heating sodium phenolate (the sodium salt of phenol) with carbon dioxide under pressure to form sodium salicylate, which is treated with sulfuric acid to liberate salicylic acid. Salicylic acid is quite irritating to skin and mucosa and it destroys epithelial cells. Absorption of large amounts can cause vomiting, abdominal pain, acidosis and mental disturbances.
