Carnauba
Carnauba (; ), 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, Paraíba, 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 ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copernicia Prunifera
''Copernicia prunifera'' or the carnaúba palm or carnaubeira palm () is a species of palm tree native to northeastern Brazil (mainly the states of Ceará, Piauí, Maranhão, Rio Grande do Norte and Bahia). Known by many as 'tree of life' because of its many uses, the Carnaúba is also the symbol tree of Ceará. The initiative to use it as a symbol vies to promote its conservation and sustainable use. Plant description ''Copernica prunifera'' can grow up to 20 m height with an average 25 cm diameter trunk, circular tree crown, with fan-leaves measuring 1.5 m, bisexual flowers and small black round fruits (2.5 cm). The palm can live up to 200 years. Although it withstands drought well, it has a high water requirement for growth. A slightly saline composition in the soil produces the best trees. Carnaubas are social palm trees, they are found in Carnaubais (assembly/group of Carnaubas) in flood zones or near rivers. Taxonomically, this tree belongs to the subfamily ...

Shoe Polish
Shoe polish, also known as boot polish and shoeshine, is a waxy paste (rheology), paste, cream (pharmaceutical), cream, or liquid that is used to polish, polishing, shine, and waterproofing, waterproof leather shoes or boots to extend the footwear's lifespan and restore its appearance. Shoe polishes are distinguished by their textures, which range from liquids to hard waxes. Solvent, waxes, and Colourant, colorants comprise most shoe polishes. Shoe polishes that would be recognizable today have been around since the Middle Ages. Originally made with dubbin, they were only used to soften leather and weather proof shoes, they did not shine shoes. However, the popularity of shoeshiner, shoe shining that arose during the early 1900s led to many shoe polish formulas being incorporated with a shining agent. 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 Wax, waxes, Solvent, sol ...

Sweets
Candy, alternatively called sweets or lollies, is a confection that features sugar as a principal ingredient. The category, also called ''sugar confectionery'', encompasses any sweet confection, including chocolate, chewing gum, and sugar candy. Vegetables, fruit, or nuts which have been glazed and coated with sugar are said to be '' candied''. Physically, candy is characterized by the use of a significant amount of sugar or sugar substitutes. Unlike a cake or loaf of bread that would be shared among many people, candies are usually made in smaller pieces. However, the definition of candy also depends upon how people treat the food. Unlike sweet pastries served for a dessert course at the end of a meal, candies are normally eaten casually, often with the fingers, as a snack between meals. Each culture has its own ideas of what constitutes candy rather than dessert. The same food may be a candy in one culture and a dessert in another. History The word candy entered the Eng ...

Polishing
Polishing is the process of creating a smooth and shiny surface by rubbing it or by applying a chemical treatment, leaving a clean surface with a significant specular reflection (still limited by the index of refraction of the material according to the Fresnel equations). In some materials (such as metals, glasses, black or transparent stones), polishing is also able to reduce diffuse reflection to minimal values. When an unpolished surface is magnified thousands of times, it usually looks like a succession of mountains and valleys. By repeated abrasion, those "mountains" are worn down until they are flat or just small "hills". The process of polishing with abrasives starts with a coarse grain size and gradually proceeds to the finer ones to efficiently flatten the surface imperfections and to obtain optimal results. Mechanical properties The strength of polished products can be higher than their unpolished counterparts owing to the removal of stress concentrations pres ...

Coated Paper
Coated paper (also known as enamel paper, gloss paper, and thin paper) is paper that has been coated with a mixture of materials or a polymer to impart certain qualities to the paper, including weight, surface gloss, smoothness, or reduced ink absorbency. Various materials, including kaolinite, calcium carbonate, bentonite, and talc, can be used to coat paper for high-quality printing, such as that used in the packaging industry and in magazines. The chalk or china clay is bound to the paper with synthetic s, such as styrene-butadiene latexes and natural organic binders such as starch. The coating formulation may also contain chemical additives as dispersants, resins, or polyethylene to give water resistance and wet strength to the paper, or to protect against ultraviolet radiation. Coated papers have been traditionally used for printing magazines. Varieties Machine-finished coated paper ''Machine-finished coated paper'' (MFC) has a basis weight of 48–80 g/m2. Th ...
