Jojoba Ester
Jojoba esters are the hydrogenation or transesterification product of Jojoba oil. Jojoba Esters are commonly used in cosmetic formulations as an emollient, due to its remarkable similarity to the natural oils produced by the human skin, and its high oxidative stability. Fully hydrogenated jojoba esters are most often small beads used to exfoliate the skin. Chemical structure Jojoba esters are proper waxes; there is no triglyceride component of jojoba esters. Chemically, jojoba esters are a complex mixture of long chain fatty acids and fatty alcohols joined by an ester bond, resulting in a total length of 36 to 46 carbon atoms. Jojoba esters are produced by the interesterification of jojoba oil, hydrogenated jojoba oil, or a mixture of the two. Pure jojoba oil and pure hydrogenated jojoba oil are also correctly described as jojoba esters. The CTFA does not regard ''partially''-hydrogenated jojoba oil as jojoba esters. For this reason, jojoba esters must not contain any trans-un ...

Hydrogenation
Hydrogenation is a chemical reaction between molecular hydrogen (H2) and another compound or element, usually in the presence of a catalyst such as nickel, palladium or platinum. The process is commonly employed to reduce or saturate organic compounds. Hydrogenation typically constitutes the addition of pairs of hydrogen atoms to a molecule, often an alkene. Catalysts are required for the reaction to be usable; non-catalytic hydrogenation takes place only at very high temperatures. Hydrogenation reduces double and triple bonds in hydrocarbons. Process Hydrogenation has three components, the unsaturated substrate, the hydrogen (or hydrogen source) and, invariably, a catalyst. The reduction reaction is carried out at different temperatures and pressures depending upon the substrate and the activity of the catalyst. Related or competing reactions The same catalysts and conditions that are used for hydrogenation reactions can also lead to isomerization of the alkenes fr ...

Coconut Oil
frameless , right , alt = A cracked coconut and a bottle of coconut oil Coconut oil (or coconut butter) is an edible oil derived from the wick, meat, and milk of the coconut palm fruit. Coconut oil is a white solid fat; in warmer climates during the summer months it is a clear thin liquid oil, melting at warmer room temperatures of around . Unrefined varieties have a distinct coconut aroma. It is used as a food oil, and in industrial applications for cosmetics and detergent production. Due to its high levels of saturated fat, numerous health authorities recommend limiting its consumption as a food.Media summary: Production Oil production is dependent upon palm cultivation. Oil production is thus threatened by coconut pests. This means most significantly the ''Oryctes'' rhinoceros beetles especially the Asiatic Rhinoceros Beetle ('' O. rhinoceros'') and the Red Palm Weevil ('' Rhynchophorus ferrugineus''). Coconut oil can be extracted through a wet or dry process. M ...

Spermaceti
Spermaceti is a waxy substance found in the head cavities of the sperm whale (and, in smaller quantities, in the oils of other whales). Spermaceti is created in the spermaceti organ inside the whale's head. This organ may contain as much as of spermaceti. It has been extracted by whalers since the 17th century for human use in cosmetics, textiles, and candles. Theories for the spermaceti organ's biological function suggest that it may control buoyancy, may act as a focusing apparatus for the whale's sense of echolocation, or possibly both. There has been concrete evidence to support both theories. The buoyancy theory holds that the sperm whale is capable of heating the spermaceti, lowering its density and thus allowing the whale to float; in order for the whale to sink again, it must take water into its blowhole which cools the spermaceti into a denser solid. This claim has been called into question by recent research which indicates a lack of biological structures to support ...

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 derives from the whale oil (''cetacea'' oil, from la, cetus, lit=whale, from grc, κῆτος, translit= kētos, lit=huge fish) 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 reduction of palmitic acid, which is obtained from palm oil. Uses 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 nuts and bolts, and is ...

PEG-150 Jojoba
PEG-150 hydrogenated jojoba is an ethoxylated version of fully hydrogenated jojoba wax and the most water soluble form of jojoba available. This versatile emollient functions as a secondary emulsifier and provides viscosity adjustments in hair care formulas and fragrance oil solubilization in aqueous solutions. PEG-150 Hydrogenated Jojoba is commonly used in cosmetics formulations. Physical properties PEG-150 hydrogenated jojoba is a solid, flaked, free-flowing material with a melting point of . Testing in a 5% aqueous solution shows that it has a neutral pH, high clarity in water, and low viscosity The viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of "thickness": for example, syrup has a higher viscosity than water. Viscosity quantifies the inte .... The HLB value is approximately 18.

Ethoxylation
Ethoxylation is a chemical reaction in which ethylene oxide adds to a substrate. It is the most widely practiced alkoxylation, which involves the addition of epoxides to substrates. In the usual application, alcohols and phenols are converted into R(OC2H4)nOH where n ranges from 1 to 10. Such compounds are called alcohol ethoxylates. Alcohol ethoxylates are often converted to related species called ethoxysulfates. Alcohol ethoxylates and ethoxysulfates are surfactants, used widely in cosmetic and other commercial products. The process is of great industrial significance with more than 2,000,000 metric tons of various ethoxylates produced worldwide in 1994. Production The process was developed at the Ludwigshafen laboratories of IG Farben by Conrad Schöller and during the 1930s. Alcohol ethoxylates Industrial ethoxylation is primarily performed upon fatty alcohols in order to generate fatty alcohol ethoxylates (FAE's), which are a common form of nonionic surfactant (e.g. octa ...

Shampoos
Shampoo () is a hair care product, typically in the form of a viscous liquid, that is used for cleaning hair. Less commonly, shampoo is available in solid bar format. Shampoo is used by applying it to wet hair, massaging the product into the scalp, and then rinsing it out. Some users may follow a shampooing with the use of hair conditioner. Shampoo is typically used to remove the unwanted build-up of sebum in the hair without stripping out so much as to make hair unmanageable. Shampoo is generally made by combining a surfactant, most often sodium lauryl sulfate or sodium laureth sulfate, with a co-surfactant, most often cocamidopropyl betaine in water. The sulfate ingredient acts as a surfactant, trapping oils and other contaminants, similarly to soap. Specialty shampoos are marketed to people with dandruff, color-treated hair, gluten or wheat allergies, an interest in using an organic product, infants and young children (" baby shampoo" is less irritating). There ar ...

Lipstick
Lipstick is a cosmetic product used to apply coloration and texture to lips, often made of wax and oil. Different pigments are used to produce color, and minerals such as silica may be used to provide texture. The use of lipstick dates back to early civilizations such as Sumer and the Indus Valley Civilisation, and was popularized in the Western world in the 16th century. Some lipsticks contain traces of toxic materials, such as lead and PFAS, which prompted health concerns and regulation. Lipstick has been prominent in several women's fashion trends, often associated with women's sexuality. The color of lipstick has aesthetic and cultural significance as different colors carry different connotations. Red lipstick has historically been associated with sensuality or women's independence while black lipstick is worn by both men and women in alternative subcultures, especially punk and goth. Celebrities such as Elizabeth Taylor, Madonna, and Taylor Swift have contributed to ...
