Acetonitrile, often abbreviated MeCN, is the chemical compound with the formula CH3CN and structure H3C−C≡N. This colourless liquid is the simplest organic nitrile. It is produced mainly as a byproduct of acrylonitrile manufacture. It is used as a polar aprotic solvent in organic synthesis and in the purification of butadiene. The N≡C−C skeleton is linear with a short C≡N distance of 1.16 Å.
Cosmetics are constituted mixtures of chemical compounds derived from either natural sources, or synthetically created ones. Cosmetics have various purposes. Those designed for personal care and skin care can be used to cleanse or protect the body or skin. Cosmetics designed to enhance or alter one's appearance (makeup) can be used to conceal blemishes, enhance one's natural features, add color to a person's face, or change the appearance of the face entirely to resemble a different person, creature or object. Cosmetics can also be designed to add fragrance to the body.
A manicure is a mostly cosmetic beauty treatment for the fingernails and hands performed at home or in a nail salon. A manicure usually consists of filing and shaping the free edge of nails, pushing and clipping any nonliving tissue, treatments with various liquids, massage of the hand, and the application of fingernail polish. When the same is applied to the toenails and feet, the treatment is referred to as a pedicure. Together, the treatments may be known as a mani-pedi. Most nail polish can stay on nails for 2–3 days before another manicure is required for maintenance, if there is no damage done to it.
Phthalates, or phthalate esters, are esters of phthalic acid. They are mainly used as plasticizers, i.e., substances added to plastics to increase their flexibility, transparency, durability, and longevity. They are used primarily to soften polyvinyl chloride (PVC). Note that while phthalates are usually plasticizers, not all plasticizers are phthalates. The two terms are specific and unique and cannot be used interchangeably.
Cosmetology is the study and application of beauty treatment. Branches of specialty include hairstyling, skin care, cosmetics, manicures/pedicures, non-permanent hair removal such as waxing and sugaring, and permanent hair removal processes such as electrology and intense pulsed light (IPL).
A plasticizer is a substance that is added to a material to make it softer and more flexible, to increase its plasticity, to decrease its viscosity, and/or to decrease friction during its handling in manufacture.
Polymer clay is a type of hardenable modeling clay based on the polymer polyvinyl chloride (PVC). It typically contains no clay minerals, but like mineral clay a liquid is added to dry particles until it achieves gel-like working properties, and similarly, the part is put into an oven to harden, hence its colloquial designation as clay. Polymer clay is generally used for making arts and craft items, and is also used in commercial applications to make decorative parts. Art made from polymer clay can now be found in major museums.
Paint stripper or paint remover is a chemical product designed to remove paint, finishes, and coatings, while also cleaning the underlying surface.
Air fresheners are products designed to reduce unwanted odors in indoor spaces, or to introduce pleasant fragrances, or both. They typically emit fragrance to mask odors, but may use other methods of action such as absorbing, bonding to, or chemically altering compounds in the air that produce smells, killing organisms that produce smells, or disrupting the sense of smell to reduce perception of unpleasant smells.
Ethyl acetate is the organic compound with the formula CH3CO2CH2CH3, simplified to C4H8O2. This colorless liquid has a characteristic sweet smell and is used in glues, nail polish removers, and in the decaffeination process of tea and coffee. Ethyl acetate is the ester of ethanol and acetic acid; it is manufactured on a large scale for use as a solvent.
Methyl acetate, also known as MeOAc, acetic acid methyl ester or methyl ethanoate, is a carboxylate ester with the formula CH3COOCH3. It is a flammable liquid with a characteristically pleasant smell reminiscent of some glues and nail polish removers. Methyl acetate is occasionally used as a solvent, being weakly polar and lipophilic, but its close relative ethyl acetate is a more common solvent being less toxic and less soluble in water. Methyl acetate has a solubility of 25% in water at room temperature. At elevated temperature its solubility in water is much higher. Methyl acetate is not stable in the presence of strong aqueous bases or aqueous acids. Methyl acetate is not considered a VOC in the USA.
Aerosol paint is paint that comes in a sealed, pressurized container and is released in an aerosol spray when a valve button is depressed. The propellant is what the container of pressurized gas is called. When the pressure holding the gas is released through the valve, the aerosol paint releases as a fine spray. Aerosol painting is one form of spray painting; it leaves a smooth, even coat, unlike many traditional rolled and brushed paints. Aerosol primer can be applied directly to bare metal and many plastics.
Diisobutyl phthalate (DIBP) is a phthalate ester having the structural formula C6H4(COOCH2CH 2)2. It is formed by the esterification of isobutanol and phthalic anhydride. This and other phthalates are used as plasticizers due to their flexibility and durability. They are found in many industrial and personal products, such as lacquers, nail polish and cosmetics. DIBP can be absorbed via oral ingestion and dermal exposure. When it comes to excretion, DIBP is first converted into the hydrolytic monoester monoisobutyl phthalate (MIBP). The primary excretory route is urine, with biliary excretion being noted in minor amounts. DIBP has lower density and freezing point than the related compound dibutyl phthalate (DBP).
Nitroethane is an organic compound having the chemical formula C2H5NO2. Similar in many regards to nitromethane, nitroethane is an oily liquid at standard temperature and pressure. Pure nitroethane is colorless and has a fruity odor.
Cellulose acetate phthalate (CAP), also known as cellacefate (INN) and cellulosi acetas phthalas, is a commonly used polymer phthalate in the formulation of pharmaceuticals, such as the enteric coating of tablets or capsules and for controlled release formulations. It is a cellulose polymer where about half of the hydroxyls are esterified with acetyls, a quarter are esterified with one or two carboxyls of a phthalic acid, and the remainder are unchanged. It is a hygroscopic white to off-white free-flowing powder, granules, or flakes. It is tasteless and odorless, though may have a weak odor of acetic acid. Its main use in pharmaceutics is with enteric formulations. It can be used together with other coating agents, e.g. ethyl cellulose. Cellulose acetate phthalate is commonly plasticized with diethyl phthalate, a hydrophobic compound, or triethyl citrate, a hydrophilic compound; other compatible plasticizers are various phthalates, triacetin, dibutyl tartrate, glycerol, propylene glycol, tripropionin, triacetin citrate, acetylated monoglycerides, etc.
A nail salon or nail bar is a specialty beauty salon establishment that primarily offers nail care services such as manicures, pedicures, and nail enhancements. Often, nail salons also offer skin care services. Manicures are also offered by general beauty salons, spas, and hotels. People who work at nail salons are usually called nail technicians, manicurists, or nailists.
Artificial nails, also known as fake nails, false nails, acrylic nails, nail extensions or nail enhancements, are extensions placed over fingernails as fashion accessories. Many artificial nail designs attempt to mimic the appearance of real fingernails as closely as possible, while others may deliberately stray in favor of an artistic look.
Nail art is a creative way to paint, decorate, enhance, and embellish nails. It is a type of artwork that can be done on fingernails and toenails, usually after manicures or pedicures.
Women's Voices for the Earth (WVE) is a feminist, women-led, North American environmental organization that specializes in research and advocacy regarding toxic chemicals used in products that disproportionately impact women's health, including cosmetics, menstrual care products, professional salon and cleaning products. WVE is a non-profit organization whose mission is to amplify women's voices to eliminate toxics that harm communities and health. With its inclusive vision of environmental work WVE has become a hub for visionary feminist environmentalism that recognizes the systemic connections between health, class, race, and the environment. Addressing the inter-connectivity of these various channels of exposure to toxic chemicals has been key to WVE's approach which is multi-scalar: targeting consumer behaviors, corporate practices, and government policies.
A migrant nail salon worker is a nail technician, manicurist, esthetician, or masseuse working in a Migrant, often Asian–owned nail salon in America. These workers are typically women who have immigrated from South Korea, though there are also Latina and Chinese immigrants employed by these shops. The majority of women who work in these nail salons are paid low wages, exposed to dangerous chemicals because of weak regulations, and develop complicated relationships with their clients, largely due to language differences and contradicting views on what constitutes quality customer service. Most Korean-owned nail salons are located in New York, and in reaction to a 2015 New York Times exposé documenting corruption within the state's nail salon industry, Gov. Andrew Cuomo created the New York State Nail Industry Enforcement Task Force, and signed into law stricter salon regulations and required the posting of wage bonds.
