Shoe Polish
Shoe polish (or boot polish) is a waxy paste, cream, or liquid that is used to polish, shine, and waterproof leather shoes or boots to extend the footwear's life and restore its appearance. Shoe polishes are distinguished by their textures, which range from liquids to hard waxes. Solvent, waxes, and colorants comprise most shoe polishes. Types Shoe polish can be classified into three types: wax, cream-emulsion, and liquid. Each differs in detailed composition but all consist of a mixture of waxes, solvent, and dyes. Wax-based shoe polish Waxes, organic solvents and colorant (either soluble dyes or pigment) compose this type of polish. Waxes are 20–40% of the material. Natural waxes used for the polish include carnauba and montan as well as synthetic waxes. The composition determines the hardness and polishing properties after solvent has evaporated. Solvents are selected to match the waxes. About 70% of shoe polish is solvent. A variety of solvents are used inc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nigrosine
In staining dyes, nigrosin (CI 50415, Solvent black 5) is a mixture of black synthetic dyes made by heating a mixture of nitrobenzene, aniline, and hydrochloric acid in the presence of copper or iron. Related to induline, it is a mixture of phenazine-based compounds. Its main industrial uses are as a colorant for lacquers and varnishes and in marker pen inks. Sulfonation of nigrosin yields a water-soluble anionic dye, nigrosin WS (CI 50420, Acid black 2). Uses Aside from its main use in lacquers, small amounts of nigrosin are used for negative staining of bacteria. as well as the capsule-containing fungus ''Cryptococcus neoformans''. The shapes and sizes of the organisms are seen as color-free outlines against the dark background. An advantage of using this method, rather than regular positive stains like methylene blue or carbol fuchsin, is that prior fixation by heat or alcohol Alcohol most commonly refers to: * Alcohol (chemistry), an organic compound in which a hydroxyl ...

Casein
Casein ( , from Latin ''caseus'' "cheese") is a family of related phosphoproteins ( αS1, aS2, β, κ) that are commonly found in mammalian milk, comprising about 80% of the proteins in cow's milk and between 20% and 60% of the proteins in human milk. Sheep and buffalo milk have a higher casein content than other types of milk with human milk having a particularly low casein content. Casein has a wide variety of uses, from being a major component of cheese, to use as a food additive. The most common form of casein is sodium caseinate. In milk, casein undergoes phase separation to form colloidal casein micelles, a type of secreted biomolecular condensate. As a food source, casein supplies amino acids, carbohydrates, and two essential elements, calcium and phosphorus. Composition Casein contains a high number of proline amino acids which hinder the formation of common secondary structural motifs of proteins. There are also no disulfide bridges. As a result, it has rel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plastic Bottle
A plastic bottle is a bottle constructed from high-density or low density plastic. Plastic bottles are typically used to store liquids such as water, soft drinks, motor oil, cooking oil, medicine, shampoo, milk, and ink. The size ranges from very small bottles to large carboys. Consumer blow molded containers often have integral handles or are shaped to facilitate grasping. Plastic was invented in the 19th century and was originally used to replace common materials such as ivory, rubber, and shellac. Plastic bottles were first used commercially in 1947, but remained relatively expensive until the early 1950s when high-density polyethylene was introduced. They quickly became popular with both manufacturers and customers because compared to glass bottles, plastic bottles are lighter, cheaper and easier to transport. However, the biggest advantage plastic bottles have over their glass counterparts is their superior resistance to breakage, in both production and transportation. ...

Montan Wax
Montan wax, also known as lignite wax or OP wax, is a hard wax obtained by solvent extraction of certain types of lignite or brown coal. Commercially viable deposits exist in only a few locations, including Amsdorf, Germany, and in the Ione Basin near Ione, California. High-graded lignite wax are also found in Yunnan and Jilin, China. Properties Its color ranges from dark brown to light yellow when crude, or white when refined. Its composition is non-glyceride long-chain (C24–C30) carboxylic acid esters (62–68 weight %), free long-chain organic acids (22–26%), long-chain alcohols, ketones, and hydrocarbons (7–15%), and resins; it is in effect a fossilized plant wax. Its melting range is 82–95 °C. Uses It is used for making car and shoe polishes, paints, and phonograph records, musical instrument polish and as lubricant for moulding paper and plastics. About a third of total world production is used in car polish. Formerly, its main use was making carbon paper. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beeswax
Beeswax (''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. Production The beeswax is formed by worker bees, which secrete it from eight wax-producing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carnauba Wax
Carnauba (; pt, carnaúba ), also called Brazil wax and palm wax, is a wax of the leaves of the carnauba palm ''Copernicia prunifera'' (synonym: ''Copernicia cerifera''), a plant native to and grown only in the northeastern Brazilian states of Ceará, Piauí, Pernambuco, Rio Grande do Norte, Maranhão and Bahia. It is known as the "Queen of Waxes". In its pure state, it is usually available in the form of hard yellow-brown flakes. It is obtained by collecting and drying the leaves, beating them to loosen the wax, then refining and bleaching it. As a food additive, its E number is E903. Composition Carnauba consists mostly of aliphatic esters (40 wt%), diesters of 4-hydroxycinnamic acid (21.0 wt%), ω-hydroxycarboxylic acids (13.0 wt%), and fatty alcohols (12 wt%). The compounds are predominantly derived from acids and alcohols in the C26-C30 range. It is distinctive for its high content of diesters and its methoxycinnamic acid. It is sold in grades of T1, T3 and T4 accordi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Morpholine
Morpholine is an organic chemical compound having the chemical formula O( C H2CH2)2 NH. This heterocycle features both amine and ether functional groups. Because of the amine, morpholine is a base; its conjugate acid is called morpholinium. For example, treating morpholine with hydrochloric acid makes the salt morpholinium chloride. It is a colorless liquid with a weak, ammonia- or fish-like odor. The naming of morpholine is attributed to Ludwig Knorr, who incorrectly believed it to be part of the structure of morphine. Production Morpholine is often produced industrially by the dehydration of diethanolamine with sulfuric acid: : Uses Industrial applications Morpholine is a common additive, in parts per million concentrations, for pH adjustment in both fossil fuel and nuclear power plant steam systems. Morpholine is used because its volatility is about the same as water, so once it is added to the water, its concentration becomes distributed rather evenly in both the water ...

Stoddard Solution
White spirit (AU, UK & Ireland)Primarily in the United Kingdom and Australia. In New Zealand "white spirit" can also refer to Coleman fuel (white gas). or mineral spirits (US, Canada), also known as mineral turpentine (AU/NZ), turpentine substitute, and petroleum spirits, is a petroleum-derived clear liquid used as a common organic solvent in painting. There are also terms for specific kinds of white spirit, including Stoddard solvent and solvent naphtha (petroleum). White spirit is often used as a paint thinner, or as a component thereof, though paint thinner is a broader category of solvent. Odorless mineral spirits (OMS) have been refined to remove the more toxic aromatic compounds, and are recommended for applications such as oil painting. A mixture of aliphatic, open-chain or alicyclic C7 to C12 hydrocarbons, white spirit is insoluble in water and is used as an extraction solvent, as a cleaning solvent, as a degreasing solvent and as a solvent in aerosols, paints, wood p ...

Stearin
Stearin , or tristearin, or glyceryl tristearate is an odourless, white powder. It is a triglyceride derived from three units of stearic acid. Most triglycerides are derived from at least two and more commonly three different fatty acids. Like other triglycerides, stearin can crystallise in three polymorphs. For stearin, these melt at 54 (α-form), 65, and (β-form). Note that stearin is also used to mean the solid component of an oil or fat that can be separated into components that melt at higher (the stearin) and lower (the olein) temperatures. This is the usage meant in an example such as palm stearin. Occurrence Stearin is obtained from animal fats created as a byproduct of processing beef. It can also be found in tropical plants such as palm. It can be partially purified by dry fractionation by pressing tallow or other fatty mixtures, leading to separation of the higher melting stearin-rich material from the liquid, which is typically enriched in fats derived from ol ...
