In female elephants, the two compounds 3-ethyl phenol and 2-ethyl 4,5 dimethylphenol have been detected in urine samples. [70] Temporal glands secretion examination showed the presence of phenol, m-cresol and p-cresol (4-methyl phenol) during musth in male elephants. [71] [72] [73] p-Cresol and o-cresol are also components of the human sweat.
Phenol and its vapors are corrosive to the eyes, the skin, and the respiratory tract. [62] Its corrosive effect on skin and mucous membranes is due to a protein-degenerating effect. [51] Repeated or prolonged skin contact with phenol may cause dermatitis, or even second and third-degree burns. [63] Inhalation of phenol vapor may cause lung ...
The main source of polyphenols is dietary, since they are found in a wide array of phytochemical-bearing foods.For example, honey; most legumes; fruits such as apples, blackberries, blueberries, cantaloupe, pomegranate, cherries, cranberries, grapes, pears, plums, raspberries, aronia berries, and strawberries (berries in general have high polyphenol content [5]) and vegetables such as broccoli ...

A phenol-croton oil is a type of chemical peel. [7] The term "phenol-croton oil peel" has replaced the vague term "phenol peel" in medical literature. It was originally used on a clandestine basis by early Hollywood stars in the 1920s and was incorporated into mainstream practice in the 1960s by Thomas Baker and Howard Gordon. [8]
In 1834, German chemist Friedlieb Ferdinand Runge discovered a phenol, also known as carbolic acid, which he derived in an impure form from coal tar.In August 1865, Joseph Lister applied a piece of lint dipped in carbolic acid solution to the wound of an eleven-year-old boy at Glasgow Royal Infirmary, who had sustained a compound fracture after a cart wheel had passed over his leg.
Chloroxylenol, also known as para-chloro-meta-xylenol (PCMX), is a chlorine substituted phenol with a white to off-white appearance and a phenolic odor.. The discovery of chloroxylenol was the result of efforts to produce improved antiseptics that began at the end of the 1800s, when scientists gradually realized that more substituted and more lipophilic phenols are less toxic, less irritant ...
The production and use of nonylphenol and nonylphenol ethoxylates is prohibited for certain situations in the European Union due to its effects on health and the environment. [ 2 ] [ 51 ] In Europe, due to environmental concerns, they also have been replaced by more expensive alcohol ethoxylates , which are less problematic for the environment ...
