<span class="mw-page-title-main">Propylene glycol</span> Chemical compound

Propylene glycol (IUPAC name: propane-1,2-diol) is a viscous, colorless liquid. It is almost odorless and has a faintly sweet taste. Its chemical formula is CH3CH(OH)CH2OH. As it contains two alcohol groups, it is classed as a diol. An aliphatic diol may also be called a glycol. It is miscible with a broad range of solvents, including water, acetone, and chloroform. In general, glycols are non-irritating and have very low volatility.

<span class="mw-page-title-main">Neomycin</span> Type of antibiotic

Neomycin is an aminoglycoside antibiotic that displays bactericidal activity against Gram-negative aerobic bacilli and some anaerobic bacilli where resistance has not yet arisen. It is generally not effective against Gram-positive bacilli and anaerobic Gram-negative bacilli. Neomycin comes in oral and topical formulations, including creams, ointments, and eyedrops. Neomycin belongs to the aminoglycoside class of antibiotics that contain two or more amino sugars connected by glycosidic bonds.

<i>p</i>-Phenylenediamine Chemical compound

p-Phenylenediamine (PPD) is an organic compound with the formula C6H4(NH2)2. This derivative of aniline is a white solid, but samples can darken due to air oxidation. It is mainly used as a component of engineering polymers and composites like kevlar. It is also an ingredient in hair dyes and is occasionally used as a substitute for henna.

<span class="mw-page-title-main">Contact dermatitis</span> Inflammation from allergen or irritant exposure

Contact dermatitis is a type of acute or chronic inflammation of the skin caused by exposure to chemical or physical agents. Symptoms of contact dermatitis can include itchy or dry skin, a red rash, bumps, blisters, or swelling. These rashes are not contagious or life-threatening, but can be very uncomfortable.

<i>Ruta</i> Genus of shrubs in the family Rutaceae

Ruta is a genus of strongly scented evergreen subshrubs, 20–60 cm tall, in the family Rutaceae, native to the Mediterranean region, Macaronesia and southwest Asia. About ten species are accepted in the genus. The most well-known species is Ruta graveolens.

<span class="mw-page-title-main">Aroma compound</span> Chemical compound that has a smell or odor

An aroma compound, also known as an odorant, aroma, fragrance or flavoring, is a chemical compound that has a smell or odor. For an individual chemical or class of chemical compounds to impart a smell or fragrance, it must be sufficiently volatile for transmission via the air to the olfactory system in the upper part of the nose. As examples, various fragrant fruits have diverse aroma compounds, particularly strawberries which are commercially cultivated to have appealing aromas, and contain several hundred aroma compounds.

<span class="mw-page-title-main">Quaternium-15</span> Salt used as a surfactant

Quaternium-15 is a quaternary ammonium salt that has been used as a surfactant and preservative. It acts as an antimicrobial agent because it slowly releases formaldehyde, which is a preservative with biocidal properties.

<span class="mw-page-title-main">Dyshidrosis</span> Inflammatory disease of the skin in humans

Dyshidrosis is a type of dermatitis, characterized by itchy vesicles of 1–2 mm in size, on the palms of the hands, sides of fingers, or bottoms of the feet. Outbreaks usually conclude within three to four weeks, but often recur. Repeated attacks may result in fissures and skin thickening. The cause of the condition is not known.

<span class="mw-page-title-main">Bronopol</span> Chemical compound

Bronopol is an organic compound that is used as an antimicrobial. It is a white solid although commercial samples appear yellow.

A patch test is a diagnostic method used to determine which specific substances cause allergic inflammation of a patient's skin.

Cocamidopropyl betaine (CAPB) is a mixture of closely related organic compounds derived from coconut oil and dimethylaminopropylamine. CAPB is available as a viscous pale yellow solution and it is used as a surfactant in personal care products and animal husbandry. The name reflects that the major part of the molecule, the lauric acid group, is derived from coconut oil. Cocamidopropyl betaine to a significant degree has replaced cocamide DEA.

Hydroxymethylpentylcyclohexenecarboxaldehyde is a synthetic fragrance known by the trade names Lyral, Kovanol, Mugonal, Landolal. It is found in some soaps, eau de toilettes, aftershaves and deodorants.

<span class="mw-page-title-main">Diazolidinyl urea</span> Antimicrobial preservative used in cosmetics.

Diazolidinyl urea is an antimicrobial preservative used in cosmetics. It is chemically related to imidazolidinyl urea which is used in the same way. Diazolidinyl urea acts as a formaldehyde releaser.

<span class="mw-page-title-main">Thiuram disulfide</span> Class of chemical compounds

Thiuram disulfides are a class of organosulfur compounds with the formula (R2NCSS)2. Many examples are known, but popular ones include R = Me and R = Et. They are disulfides obtained by oxidation of the dithiocarbamates. These compounds are used in sulfur vulcanization of rubber as well as in the manufacture of pesticides and drugs. They are typically white or pale yellow solids that are soluble in organic solvents.

<span class="mw-page-title-main">Formaldehyde releaser</span> Chemical compound used as a preservative

A formaldehyde releaser, formaldehyde donor or formaldehyde-releasing preservative is a chemical compound that slowly releases formaldehyde. Formaldehyde-releasers are added to prevent microbial growth and extend shelf life. The intent of these compounds is that they release formaldehyde at levels that suppress microbial growth but sufficiently low to not threaten humans. The use of these chemicals in cosmetics has elicited controversy.

Eyelid dermatitis is commonly related to atopic dermatitis or allergic contact dermatitis. Volatile substances, tosylamide, epoxy hardeners, insect sprays, and lemon peel oil may be implicated, with many cases of eyelid contact dermatitis being caused by substances transferred by the hands to the eyelids.

<span class="mw-page-title-main">Iodopropynyl butylcarbamate</span> Chemical compound

Iodopropynyl Butyl Carbamate (IPBC) is a water-soluble preservative used globally in the paints & coatings, wood preservatives, personal care, and cosmetics industries. IPBC is a member of the carbamate family of biocides. IPBC was invented in the 1970s and has a long history of effective use as an antifungal technology.

Methyldibromo glutaronitrile (MDBGN) is a widely used preservative.

<span class="mw-page-title-main">Nickel allergy</span> Medical condition

Nickel allergy is any of several allergic conditions provoked by exposure to the chemical element nickel. Nickel allergy often takes the form of nickel allergic contact dermatitis (Ni-ACD), a form of allergic contact dermatitis (ACD). Ni-ACD typically causes a rash that is red and itchy and that may be bumpy or scaly. The main treatment for it is avoiding contact with nickel-releasing metals, such as inexpensive jewelry. Another form of nickel allergy is a systemic form: systemic nickel allergy syndrome (SNAS) can mimic some of the symptoms of irritable bowel syndrome (IBS) and also has a dermatologic component.

<span class="mw-page-title-main">Lip licker's dermatitis</span> Medical condition

Lip licker's dermatitis is a type of skin inflammation around the lips due to damage by saliva from repetitive lip licking and is classified as a subtype of irritant contact cheilitis. The resulting scaling, redness, chapping, and crusting makes a well-defined ring around the lips. The rash may extend as far as the tongue can reach and usually does not occur at the corners of the mouth. It commonly occurs during winter months but some people can have it year-round if lip licking is a chronic habit.
