Trolamine salicylate (Aspercreme, Aspergel) is an organic compound with the chemical formula [HN(CH2CH2OH)3]+C6H4(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.
It is used as an ingredient in sunscreens, analgesic creams, and cosmetics. The salicylic acid portion contributes to both the sun protection effect (by absorbing UVB radiation) and to the analgesic effect. The triethanolamine neutralizes the acidity of the salicylic acid. One benefit of this topical analgesic is that it has no odor, in contrast to other topical analgesics such as menthol.
The US Food and Drug Administration has not reviewed any of the over-the-counter products listed in the Daily Med database that contain trolamine salicylate. [4] Also, the producers of trolamine salicylate products have not provided evidence to the FDA in support of claims that this chemical is directly absorbed through the skin into underlying tissue. [5] Due to health concerns, in 2019 the FDA issued a proposed rule classifying the sunscreen use of trolamine salicylate as "not generally recognized as safe and effective." [6] One study reported that trolamine salicylate does penetrate into, and persist within, underlying muscle tissue. The test subjects used either the trolamine salicylate product or a placebo while engaging in an exercise regimen designed to induce muscle soreness. The experimenters observed that those using the trolamine salicylate product exercised longer before reporting the onset of soreness, reported less intense soreness, and reported that their soreness did not last as long as the people who used the placebo. [7]
All of the trolamine salicylate-containing products listed in the two cited references are 10% solutions. These products are sold under various brand names, e.g. Aspercreme, and are marketed as topical analgesics for temporary relief of arthritis, simple backache, muscle strains, and sprains.
Aspirin, also known as acetylsalicylic acid (ASA), is a nonsteroidal anti-inflammatory drug (NSAID) used to reduce pain, fever, and/or inflammation, and as an antithrombotic. Specific inflammatory conditions which aspirin is used to treat include Kawasaki disease, pericarditis, and rheumatic fever.
Ketoprofen is one of the propionic acid class of nonsteroidal anti-inflammatory drugs (NSAID) with analgesic and antipyretic effects. It acts by inhibiting the body's production of prostaglandin.
Salicylic acid is an organic compound with the formula HOC6H4COOH. A colorless (or, white), bitter-tasting solid, it is a precursor to and a metabolite of acetylsalicylic acid (aspirin). It is a plant hormone, and has been listed by the EPA Toxic Substances Control Act (TSCA) Chemical Substance Inventory as an experimental teratogen. The name is from Latin salix for willow tree, from which it was initially identified and derived. It is an ingredient in some anti-acne products. Salts and esters of salicylic acid are known as salicylates.
Warts are non-cancerous viral growths usually occurring on the hands and feet but which can also affect other locations, such as the genitals or face. One or many warts may appear. They are distinguished from cancerous tumors as they are caused by a viral infection, such as a human papillomavirus, rather than a cancer growth.
Arthralgia literally means 'joint pain'. Specifically, arthralgia is a symptom of injury, infection, illness, or an allergic reaction to medication.
Benzocaine, sold under the brand name Orajel amongst others, is a local anesthetic, belonging to the amino ester drug class, commonly used as a topical painkiller or in cough drops. It is the active ingredient in many over-the-counter anesthetic ointments such as products for oral ulcers. It is combined with antipyrine to form A/B ear drops. In the US, products containing benzocaine for oral application are contraindicated in children younger than two years old. In the European Union, the contraindication applies to children under 12 years of age.
Delayed onset muscle soreness (DOMS) is the pain and stiffness felt in muscles after unaccustomed or strenuous exercise. The soreness is felt most strongly 24 to 72 hours after the exercise. It is thought to be caused by eccentric (lengthening) exercise, which causes small-scale damage (microtrauma) to the muscle fibers. After such exercise, the muscle adapts rapidly to prevent muscle damage, and thereby soreness, if the exercise is repeated.
Methyl salicylate (oil of wintergreen or wintergreen oil) is an organic compound with the formula C8H8O3. It is the methyl ester of salicylic acid. It is a colorless, viscous liquid with a sweet, fruity odor reminiscent of root beer (in which it is used as a flavoring), but often associatively called "minty", as it is an ingredient in mint candies. It is produced by many species of plants, particularly wintergreens. It is also produced synthetically, used as a fragrance and as a flavoring agent.
Liniment, also called embrocation and heat rub, is a medicated topical preparation for application to the skin. Some liniments have viscosity similar to that of water; others are lotion or balm; still others are in transdermal patches, soft solid sticks, and sprays. Liniment usually is rubbed in to the skin, which the active ingredients penetrate.
Betamethasone is a steroid medication. It is used for a number of diseases including rheumatic disorders such as rheumatoid arthritis and systemic lupus erythematosus, skin diseases such as dermatitis and psoriasis, allergic conditions such as asthma and angioedema, preterm labor to speed the development of the baby's lungs, Crohn's disease, cancers such as leukemia, and along with fludrocortisone for adrenocortical insufficiency, among others. It can be taken by mouth, injected into a muscle, or applied to the skin, typically in cream, lotion, or liquid forms.
Triethanolamine, or TEOA, is an organic compound with the chemical formula N(CH2CH2OH)3. It is a colourless, viscous liquid. It is both a tertiary amine and a triol. A triol is a molecule with three alcohol groups. Approximately 150,000 tonnes were produced in 1999. It is a colourless compound although samples may appear yellow because of impurities.
Cysteamine is an organosulfur compound with the formula HSCH2CH2NH2. A white, water-soluble solid, it contains both an amine and a thiol functional groups. It is often used as salts of the ammonium derivative [HSCH2CH2NH3]+ including the hydrochloride, phosphocysteamine, and the bitartrate.The intermediate pantetheine is broken down into cysteamine and pantothenic acid.
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. 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.
Bengay, spelled Ben-Gay before 1995, is a topical analgesic heat rub for temporary relief from muscle and joint pain associated with arthritis, bruises, simple backaches, overuse, sprains and strains.
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. Contained in 45% of U.S. sunscreens, it is used as a chemical UV filter. The salicylic acid portion of the molecule absorbs ultraviolet rays with a wavelength from 295 nm to 315 nm, protecting the skin from sun damage. The hydrophobic trimethyl cyclohexyl group provides greasiness that prevents it from dissolving in water.
RUB A535 is a rubefacient introduced in 1919 and manufactured by Church & Dwight in Montreal, Quebec, Canada.
Phenyl salicylate, or salol, is the organic compound with the formula C6H5O2C6H4OH. It is a white solid. It is occasionally used in sunscreens and as an antiseptic.
