Hydroxysultaine
Hydroxysultaines are chemical compounds used in high-foaming shampoos, bath products and shower gels especially in conjunction with ether sulfates and alkyl sulfates. They are also used in industrial applications where high, stable foam is required. Chemically, hydroxysultaines are zwitterionic, typically containing covalently linked positive and negative ions. Synthesis Hydroxysultaine is prepared industrially by the reaction of sodium bisulfite with epichlorohydrin to give the sodium salt (sodium 1-chloro-2-hydroxypropane sulfonate). This is similar to the synthesis of isethionate, which is also used as a 'head-group' in surfactants. It is typically combined with the rest of the surfactant molecule via a Menshutkin reaction with a tertiary amine. Properties Hydroxysultaines are also compatible with cationic surfactants and are stable over a wide pH range in soft or hard water. In addition to being used as a surfactant, hydroxysultaines are often used as antistatic agents. E ...

Cocamide
Cocamide is a mixture of amides manufactured from the fatty acids obtained from coconut oil. As coconut oil contains about 50% of lauric acid, in formulas only the 12-carbon chains tend to be considered. Therefore the formula of cocamide can be written as , though the number of carbon atoms in the chains varies (it is always even). Cocamide is the structural basis of many surfactants. Common are ethanolamines (cocamide MEA, cocamide DEA), betaine compounds (cocamidopropyl betaine), and hydroxysultaines (cocamidopropyl hydroxysultaine Cocamidopropyl hydroxysultaine (CAHS) is a synthetic amphoteric surfactant from the hydroxysultaine group.

Surfactant
Surfactants are chemical compounds that decrease the surface tension or interfacial tension between two liquids, a liquid and a gas, or a liquid and a solid. The word ''surfactant'' is a Blend word, blend of "surface-active agent", coined in 1950. As they consist of a water-repellent and a water-attracting part, they enable water and oil to mix; they can form foam and facilitate the detachment of dirt. Surfactants are among the most widespread and commercially important chemicals. Private households as well as many industries use them in large quantities as detergent, detergents and cleaning agents, but also for example as emulsion#Emulsifiers, emulsifiers, wetting agents, foaming agents, Antistatic agent, antistatic additives, or dispersants. Surfactants occur naturally in traditional plant-based detergents, e.g. Aesculus, horse chestnuts or Sapindus, soap nuts; they can also be found in the secretions of some caterpillars. Today one of the most commonly used anionic surfa ...

Lauric Acid
Lauric acid, systematically dodecanoic acid, is a saturated fatty acid with a 12-carbon atom chain, thus having many properties of Medium-chain triglyceride, medium-chain fatty acids. It is a bright white, powdery solid with a faint odor of Pimenta racemosa, bay oil or soap. The salt (chemistry), salts and esters of lauric acid are known as laurates. Occurrence Lauric acid, as a component of triglycerides, comprises about half of the fatty-acid content in coconut milk, coconut oil, Laurus nobilis, laurel oil, and palm kernel oil (not to be confused with palm oil).David J. Anneken, Sabine Both, Ralf Christoph, Georg Fieg, Udo Steinberner, Alfred Westfechtel "Fatty Acids" in Ullmann's Encyclopedia of Industrial Chemistry 2006, Wiley-VCH, Weinheim. Oils with high levels of lauric acid are known as ''lauric oils''. Otherwise, it is relatively uncommon. It is also found in human breast milk (6.2% of total fat), cow's milk (2.9%), and goat's milk (3.1%). In various plants *The palm tre ...

Household Chemicals
Household chemicals are non-food chemicals that are commonly found and used in and around the average household. They are a type of consumer goods, designed particularly to assist cleaning, house and yard maintenance, cooking, pest control and general hygiene purposes, often stored in the kitchen or garage. Food additives generally do not fall under this category, unless they have a use other than for human consumption. Additives in general (e.g. stabilizers and coloring found in washing powder and dishwasher detergents) make the classification of household chemicals more complex, especially in terms of health - some of these chemicals are irritants or potent allergens - and ecological effects. Together with non-compostable household waste, the chemicals found in private household commodities pose a serious ecological problem. In addition to having slightly adverse up to seriously toxic effects when swallowed, chemical agents around may contain flammable or corrosive subs ...

Erucic Acid
Erucic acid is a monounsaturated omega-9 fatty acid, denoted 22:1ω9. It has the chemical formula: . It is prevalent in wallflower seed and other plants in the family Brassicaceae, with a reported content of 20 to 54% in high erucic acid rapeseed oil and 42% in mustard oil. Erucic acid is also known as ''cis''-13-docosenoic acid and the trans isomer is known as brassidic acid. Cetoleic acid is a positional isomer of erucic acid. Uses Erucic acid is a precursor to brassylic acid, a C13-dicarboxylic acid that is used to make specialty polyamides and polyesters. The conversion entails ozonolysis, which selectively cleaves the C=C bond in erucic acid: CH3(CH2)7CH\dCH(CH2)11CO2H + O3 + 0.5 O2 -> CH3(CH2)7CO2H + HO2C(CH2)11CO2H Amides of erucic acid are used as lubricants and surfactants. Hydrogenation of erucic acid gives behenyl alcohol, , a pour point depressant (enabling liquids to flow at a lower temperature), and silver behenate, for use in photography. Sour ...

Tallow
Tallow is a rendered form of beef or mutton suet, primarily made up of triglycerides. In industry, tallow is not strictly defined as beef or mutton suet. In this context, tallow is animal fat that conforms to certain technical criteria, including its melting point. Commercial tallow commonly contains fat derived from other animals, such as lard from pigs, or even from plant sources. The solid material remaining after rendering is called cracklings, greaves, or graves. It has been used mostly for animal food, such as dog food. In the soap industry and among soap-making hobbyists, the name tallowate is used informally to refer to soaps made from tallow. Sodium tallowate, for example, is obtained by reacting tallow with sodium hydroxide (lye, caustic soda) or sodium carbonate (washing soda). It consists chiefly of a variable mixture of sodium salts of fatty acids, such as oleic and palmitic.Ruth Winter (2007): ''A Consumerýs Dictionary of Household, Yard and Office ...

Cis–trans Isomerism
''Cis''–''trans'' isomerism, also known as geometric isomerism, describes certain arrangements of atoms within molecules. The prefixes "''cis''" and "''trans''" are from Latin: "this side of" and "the other side of", respectively. In the context of chemistry, ''cis'' indicates that the functional groups (substituents) are on the same side of some plane, while ''trans'' conveys that they are on opposing (transverse) sides. ''Cis''–''trans'' isomers are stereoisomers, that is, pairs of molecules which have the same formula but whose functional groups are in different orientations in three-dimensional space. ''Cis'' and ''trans'' isomers occur both in organic molecules and in inorganic coordination complexes. ''Cis'' and ''trans'' descriptors are not used for cases of conformational isomerism where the two geometric forms easily interconvert, such as most open-chain single-bonded structures; instead, the terms "''syn''" and "''anti''" are used. According to IUPAC, "geome ...

Lipid Number
In chemistry, in particular in biochemistry, a fatty acid is a carboxylic acid with an aliphatic chain, which is either saturated or unsaturated. Most naturally occurring fatty acids have an unbranched chain of an even number of carbon atoms, from 4 to 28. Fatty acids are a major component of the lipids (up to 70% by weight) in some species such as microalgae but in some other organisms are not found in their standalone form, but instead exist as three main classes of esters: triglycerides, phospholipids, and cholesteryl esters. In any of these forms, fatty acids are both important dietary sources of fuel for animals and important structural components for cells. History The concept of fatty acid (''acide gras'') was introduced in 1813 by Michel Eugène Chevreul, though he initially used some variant terms: ''graisse acide'' and ''acide huileux'' ("acid fat" and "oily acid"). Types of fatty acids Fatty acids are classified in many ways: by length, by saturation vs unsaturatio ...

Omega-9 Fatty Acid
Omega−9 fatty acids (ω−9 fatty acids or ''n''−9 fatty acids) are a family of unsaturated fatty acids which have in common a final carbon–carbon double bond in the omega−9 position; that is, the ninth bond from the methyl end of the fatty acid. Unlike omega−3 fatty acids and omega−6 fatty acids, omega−9 fatty acids are not classed as essential fatty acids (EFA). This is both because they can be created by the human body from unsaturated fat, and are therefore not essential in the diet, and because the lack of an omega−6 double bond keeps them from participating in the reactions that form the eicosanoids. Overview Some omega−9 fatty acids are common components of animal fat and vegetable oil. Two omega−9 fatty acids important in industry are: * Oleic acid (18:1, ''n''−9), which is a main component of olive oil, macadamia oil and other monounsaturated fats * Erucic acid (22:1, ''n''−9), which is found in rapeseed, wallflower seed, and mustard seed ...

Monounsaturated
In biochemistry and nutrition, a monounsaturated fat is a fat that contains a monounsaturated fatty acid (MUFA), a subclass of fatty acid characterized by having a double bond in the fatty acid chain with all of the remaining carbon atoms being single-bonded. By contrast, polyunsaturated fatty acids (PUFAs) have more than one double bond. Molecular description Monounsaturated fats are triglycerides containing one unsaturated fatty acid. Almost invariably that fatty acid is oleic acid (18:1 n−9). Palmitoleic acid (16:1 n−7) and cis-vaccenic acid (18:1 n−7) occur in small amounts in fats. Health Studies have shown that substituting dietary monounsaturated fat for saturated fat is associated with increased daily physical activity and resting energy expenditure. More physical activity was associated with a higher-oleic acid diet than one of a palmitic acid diet. From the study, it is shown that more monounsaturated fats lead to less anger and ...
