INCI
The International Nomenclature of Cosmetic Ingredients (INCI) are the unique identifiers for cosmetic ingredients such as waxes, oils, pigments, and other chemicals that are assigned in accordance with rules established by the Personal Care Products Council (PCPC), previously the Cosmetic, Toiletry, and Fragrance Association (CTFA). INCI names often differ greatly from systematic chemical nomenclature or from more common trivial names and is a mixture of conventional scientific names, Latin and English words. INCI nomenclature conventions "are continually reviewed and modified when necessary to reflect changes in the industry, technology, and new ingredient developments". INCI and CAS The relationship between a CAS Registry Number and an INCI name is not always one-to-one. In some cases, more than one INCI name may have the same CAS number, or more than one CAS number may apply to an INCI name. For example, the CAS number 1245638-61-2 has the CA Index Name of 2-Propenoic a ...

Cosmetic Ingredients
Cosmetics ingredients come from a variety of sources but, unlike the ingredients of food, are often not considered by most consumers. Cosmetics often use vibrant colors that are derived from a wide variety of sources, ranging from crushed insects to rust.Schneider, Günther ''et al'' (2005). "Skin Cosmetics" in ''Ullmann's Encyclopedia of Industrial Chemistry'', Wiley-VCH, Weinheim. Cosmetics in a variety of forms date back to early civilizations, with the need to improve ones personal appearance being an important factor in attracting a mate. Over the years the ingredients have changed dramatically as we discovered how to manufacture our own scents and cosmetic formulas. The realization of the dangers of many common ingredients also greatly affected the growing industry. Ancient Egyptian aristocracy made use of minerals to provide colour and definition to their facial features. During the era of the Greek Empire it was common to use face paints, while cosmetics in ancient ...

Cocamidopropyl Betaine
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. Production Despite the name cocamidopropyl betaine, the molecule is not synthesized from betaine. Instead it is produced in a two-step manner, beginning with the reaction of dimethylaminopropylamine (DMAPA) with fatty acids from coconut or palm kernel oil ( lauric acid, or its methyl ester, is the main constituent). The primary amine in DMAPA is more reactive than the tertiary amine, leading to its selective addition to form an amide. In the second step chloroacetic acid reacts with the remaining tertiary amine to form a quaternary am ...

Bran
Bran, also known as miller's bran, is the component of a Cereal, cereal grain consisting of the hard layersthe combined aleurone and Fruit anatomy#Pericarp layers, pericarpsurrounding the endosperm. Maize, Corn (maize) bran also includes the pedicel (tip cap). Along with the cereal germ, germ, it is an integral part of whole grains, and is often produced as a byproduct of mill (grinding), milling in the production of refined grains. Bran is highly nutritious, but is difficult to digest due to its high fiber content; its high fat content also reduces its shelf life as the oils/fats are prone to becoming rancid. As such, it is typically removed from whole grain during the Refined grains, refining processe.g. in processing wheat grain into white flour, or refining brown rice into white rice. Bran is present in cereal grain, including rice, maize, corn (maize), wheat, oats, barley, rye, and millet. Bran is not the same as chaff, which is a coarser, scaly material surrounding the gr ...

Glycerin
Glycerol () is a simple triol compound. It is a colorless, odorless, sweet-tasting, viscous liquid. The glycerol backbone is found in lipids known as glycerides. It is also widely used as a sweetener in the food industry and as a humectant in pharmaceutical formulations. Because of its three hydroxyl groups, glycerol is miscible with water and is Hygroscopy, hygroscopic in nature. Modern use of the word glycerine (alternatively spelled glycerin) refers to commercial preparations of less than 100% purity, typically 95% glycerol. Structure Although chirality, achiral, glycerol is prochirality, prochiral with respect to reactions of one of the two primary alcohols. Thus, in substituted derivatives, the Glycerophospholipid#Nomenclature and stereochemistry, stereospecific numbering labels the molecule with a ''sn''- prefix before the stem name of the molecule. Production Natural sources Glycerol is generally obtained from plant and animal sources where it occurs in triglycerides, est ...

Beeswax
Bee hive wax complex Beeswax (also known as cera alba) is a natural wax produced by honey bees of the genus ''Apis''. The wax is formed into scales by eight wax-producing glands in the abdominal segments of worker bees, which discard it in or at the hive. The hive workers collect and use it to form cells for honey storage and larval and pupal protection within the beehive. Chemically, beeswax consists mainly of esters of fatty acids and various long-chain alcohols. Beeswax has been used since prehistory as the first plastic, as a lubricant and waterproofing agent, in lost wax casting of metals and glass, as a polish for wood and leather, for making candles, as an ingredient in cosmetics and as an artistic medium in encaustic painting. Beeswax is edible, having similarly negligible toxicity to plant waxes, and is approved for food use in most countries and in the European Union under the E number E901. However, due to its inability to be broken down by the human digestiv ...

Tocopherol
Tocopherols (; TCP) are a class of organic compounds comprising various methylated phenols, many of which have vitamin E activity. Because the vitamin activity was first identified in 1936 from a dietary fertility factor in rats, it was named ''tocopherol'', from Greek τόκος ''tókos'' 'birth' and φέρειν ''phérein'' 'to bear or carry', that is 'to carry a pregnancy', with the ending ''-ol'' signifying its status as a chemical alcohol. α-Tocopherol is the main source found in supplements and in the European diet, where the main dietary sources are olive and sunflower oils, while γ-tocopherol is the most common form in the American diet due to a higher intake of soybean and corn oil. Forms Vitamin E exists in eight different forms, four tocopherols and four tocotrienols. All feature a chromane ring, with a hydroxyl group that can donate a hydrogen atom to reduce free radicals and a hydrophobic side chain that allows for penetration into biological membranes. B ...

Vitamin E
Vitamin E is a group of eight compounds related in molecular structure that includes four tocopherols and four tocotrienols. The tocopherols function as fat-soluble antioxidants which may help protect cell membranes from reactive oxygen species. Vitamin E is classified as an essential nutrient for humans. Various government organizations recommend that adults consume between 3 and 15 mg per day, while a 2016 worldwide review reported a median dietary intake of 6.2 mg per day. Sources rich in vitamin E include seeds, nuts, vegetable oil, seed oils, Peanut butter#Nutritional profile, peanut butter, food fortification, vitamin E–fortified foods, and dietary supplements. Symptomatic vitamin E deficiency is rare, usually caused by an underlying problem with digesting dietary fat rather than from a diet low in vitamin E. Deficiency can cause neurological disorders. Tocopherols and tocotrienols both occur in α (alpha), β (beta), γ (gamma), and δ (delta) forms, as dete ...

Denatured Alcohol
Denatured alcohol, also known as methylated spirits, metho, or meths in Australia, Ireland, New Zealand, South Africa, and the United Kingdom, and as Rectified spirit, denatured rectified spirit, is ethanol that has additives to make it poisonous, bad-tasting, foul-smelling, or Vomiting#Emetics, nauseating to discourage its alcohol consumption, recreational consumption. It is sometimes dyed so that it can be identified visually. Pyridine and methanol, each and together, make denatured alcohol poisonous; denatonium makes it bitter. Denatured alcohol is used as a solvent and as fuel for alcohol burners and camping stoves. Because of the diversity of industrial uses for denatured alcohol, hundreds of additives and denaturing methods have been used. The main additive usually is 10% methanol (methyl alcohol), hence the name ''methylated spirits''. Other common additives include isopropyl alcohol, acetone, Butanone, methyl ethyl ketone, and methyl isobutyl ketone. Denaturation (food), ...

Cetyl Alcohol
Cetyl alcohol , also known as hexadecan-1-ol and palmityl alcohol, is a C-16 fatty alcohol with the formula CH3(CH2)15OH. At room temperature, cetyl alcohol takes the form of a waxy white solid or flakes. The name cetyl refers to whale oil (''cetacea'' oil, from , from ) from which it was first isolated. Preparation Cetyl alcohol was discovered in 1817 by the French chemist Michel Chevreul when he heated spermaceti, a waxy substance obtained from sperm whale oil, with caustic potash (potassium hydroxide). Flakes of cetyl alcohol were left behind on cooling. Modern production is based around the chemical reduction of ethyl palmitate. Occurrence and uses The ether chimyl alcohol, derived from cetyl alcohol and glycerol, is a component of some lipid membranes. Cetyl alcohol is used in the cosmetic industry as an opacifier in shampoos, or as an emollient, emulsifier or thickening agent in the manufacture of skin creams and lotions. It is also employed as a lubricant for ...

Paraben
Parabens are organic compounds that are commonly used as preservatives in cosmetic and pharmaceutical products. They are esters of parahydroxybenzoic acid (also known as 4-hydroxybenzoic acid). Chemistry Structure and structure Parabens are esters of ''para''-hydroxy''ben''zoic acid, from which the name is derived. Common parabens include methylparaben (E number E218), ethylparaben (E214), propylparaben (E216), butylparaben and heptylparaben (E209). Less common parabens include isobutylparaben, isopropylparaben, benzylparaben and their sodium salts. They are produced by the esterification of ''para''-hydroxybenzoic acid with the appropriate alcohol, such as methanol, ethanol, or n-propanol. ''para''-Hydroxybenzoic acid is in turn produced industrially from a modification of the Kolbe-Schmitt reaction, using potassium phenoxide and carbon dioxide. Biological mode of action Parabens are active against a broad spectrum of microorganisms. However, their antibacteri ...

Monolaurin
Monolaurin (abbreviated GML; also called glycerol monolaurate, glyceryl laurate, and 1-lauroyl-glycerol) is a monoglyceride. It is the mono-ester formed from glycerol and lauric acid. Its chemical formula is C15H30O4. Occurrence Monolaurin is found in coconut oil and may be similar to other monoglycerides found in human breast milk. Lauric acid can be ingested in coconut oil and the human body converts it into monolaurin. Furthermore, coconut oil, coconut cream, grated coconut and others products are sources of lauric acid and, consequently, monolaurin. Uses Monolaurin is most commonly used as a surfactant in cosmetics, such as deodorants. As a food additive it is also used as an emulsifier or preservative. Monolaurin is also marketed as a dietary supplement. Monolaurin is sold as a dietary supplement and as an ingredient in certain foods.
