Cresols (also known as hydroxytoluene, toluenol, benzol or cresylic acid) are a group of aromatic organic compounds. They are widely-occurring phenols (sometimes called phenolics) which may be either natural or manufactured. They are also categorized as methyl phenols.

…is also called tricresol, or cresylic acid. All three isomers are very toxic, and in high concentrations they can be absorbed in fatal amounts through the skin. The cresols are strong germicides, and in low concentrations they are effective disinfectants and antiseptics.

This mixture is also called tricresol, or cresylic acid. All three isomers are very toxic, and in high concentrations they can be absorbed in fatal amounts through the skin. The cresols are strong germicides, and in low concentrations they are effective disinfectants and antiseptics.

Cresols are a widely occurring natural and manufactured group of chemicals. In their pure form, they are colorless solids and may be liquids if they are mixtures. Cresols smell like medicine. There are three forms of cresols that differ slightly in their chemical structure: ortho-cresol (o-cresol), meta-cresol (m-cresol, and para-cresol (p-cresol).

A man who survived a 5–6-hour immersion of his hands in a concentrated cresylic acid solution experienced persistent eye watering, followed by pain on the side of his face and, ultimately, marked facial paralysis (Klinger and Norton 1945).

cresols from automobile exhaust, power plants, and oil refineries. Acute (short-term) inhalation exposure by humans to mixed cresols results in respiratory tract irritation, with . mptoms such as dryness, nasal constriction, and.

The meaning of CRESYLIC ACID is cresol; especially : a crude mixture of the three cresols.

However, cresylic acids generally are composed of cresols, phenols, and xylenols; they are defined as those mixtures in which over 50% will boil at temperatures above 204 °C . Cresols are used widely by industry.

Cresols (CAS 1319-77-3) are methylphenols, organic in nature, and occur in three isomers: o -cresol, m -cresol, and p -cresol. It is also called cresylic acid.
