2-Ethylhexyl salicylate also known as octisalate or octyl salicylate, is an organic compound used as an ingredient in sunscreens and cosmetics to absorb UVB (ultraviolet) rays from the sun. [1] It is an ester formed by the condensation of salicylic acid with 2-ethylhexanol. It is a colorless oily liquid with a slight floral odor.
The extended conjugation of the acrylate portion of the molecule absorbs UVB and short-wave UVA (ultraviolet) rays with wavelengths from 280 to 320 nm, [1] protecting the skin from direct DNA damage. The ethylhexanol portion is a fatty alcohol , adding emollient and oil-like (water resistant) properties.
Octyl methoxycinnamate is the most common active ingredient in sunscreens for protection against UV-B rays. [2] [3] It may be combined with oxybenzone and titanium oxide.[2] ...
A broad spectrum sunscreen with ecamsule, avobenzone and octocrylene significantly reduces the skin damage associated with UV exposure in human subjects. [9] In studies done in mice it reduces the formation of UV induced pyrimidine dimers and delays the onset of skin cancer. In vitro ecamsule effectively protects against the harmful effects of ...
Padimate O is an organic compound related to the water-soluble compound PABA (4-aminobenzoic acid) that is used as an ingredient in some sunscreens.This yellowish water-insoluble oily liquid is an ester formed by the condensation of 2-ethylhexanol with dimethylaminobenzoic acid.
Trolamine salicylate (Aspercreme, Aspergel) is an organic compound with the chemical formula [HN(CH 2 CH 2 OH) 3] + C 6 H 4 (OH)(COO −).It is a salt of triethanolamine and salicylic acid, i.e. the compound consists of protonated triethanolamine and the conjugate base of salicylic acid, salicate.
Homosalate is an organic compound used in some sunscreens.It is made by the Fischer–Speier esterification of salicylic acid and 3,3,5-trimethylcyclohexanol, the latter being a hydrogenated derivative of isophorone.
Light therapy, also called phototherapy or bright light therapy is the exposure to direct sunlight or artificial light at controlled wavelengths in order to treat a variety of medical disorders, including seasonal affective disorder (SAD), circadian rhythm sleep-wake disorders, cancers, neonatal jaundice, and skin wound infections.
