Algae

== Description ==
A family of chlorophyll-containing organisms that grow in water. Algae range in size from microscopic, single cells (plankton, diatoms, flagella, etc.) to giant, multicellular forms (seaweed, kelp) over 100 feet long. They are abundant in salt and fresh water providing an important source of food for aquatic life. The four main types of algae are classified by their colors: brown, red, green and blue-green. Of the four, blue-green algae is considered detrimental. It grows in stagnant ponds and thrives on phosphorus compounds often making the water toxic to fish and other animals. Additionally, blue-green algae can form stains on damp building walls. The other types of algae are an important commercial resource and are used in the production of food, fertilizers, starch, agar, and carrageenan. They contain numerous minerals, vitamins, proteins, lipids, and essential amino acids. Algicides are used to reduce or kill unwanted algae.

Algarobilla

== Description ==
A mesquite-type shrub, Caesalpinia brevifolia, with bean-like pods that is native to Chile. Dried algarobilla pods contain 45-50% water-soluble tannins of the pyrogallol class. When used prior to fermentation, the tannins produce a firm, light-color tan leather. The solution changes to an orange color upon fermentation which results in a brightly colored leather. It is similar to divi-divi, tara, and cascalote.

Algin

== Description ==
A gelling polysaccharide compound found in giant brown seaweed of the class Phaeophyceae. Algin is similar to agar. It is composed of mannuronic acid and glucuronic acids. The hydrophilic, cream-color material is extracted from the kelp and used as thickener and stabilizer in coatings and food products, such as ice cream. It is also used to produce synthetic yarns and fibers and as a blood coagulant in first aid dressings. The name algin is also used as a shortened version of alginic acid and sodium alginate. 
See also alginate fiber.

Alginic acid

== Description ==
A hydrophilic polysaccharide obtained from seaweed. Alginic acid is a stable, light yellowish fibrous solid or powder that is capable of absorbing over 200 times its weight in water. It is used as a thickener and emulsifier in food, ice cream, toothpaste, and cosmetics. Alginic acid forms water-insoluble polymeric alginates with most divalent cations (Ca++, Ba++, etc.), which are used for textile sizing, paper coatings, and to produce imitation horn, ivory, and celluloid.

Alginic fiber

== Description ==
A fine silk-like thread produced by forcing sodium alginate through spinnerets into a solution of a metallic salt, usually beryllium or calcium acetate. This changes the water-soluble alginate into a water-insoluble material. However, because the fibers will still dissolve in aqueous solutions that contain soaps or an alkali, alginic fibers must be dry-cleaned. They are commonly used as a spacing threads to produce fancy weave fabrics. The alginic fibers are woven into a fabric with other types of thread, such as fine wool, then washed out, leaving a loosely woven pattern. Alginic threads are also used to produce silk substitutes, fireproof fabrics, and surgical dressings that can dissolve into the blood stream.
== Synonyms and Related Terms ==
alginic fibre; algin fiber; alginate fiber; fibra algínica (Esp.)
== Risks ==
Nonflammable, but will decompose in flame with ash residue.
== Physical and Chemical Properties ==
Soluble in weak alkalis like soap. Unaffected by organic solvents.
Fibers are striated; cross sections have serrated edges with occasional flat spots. Tenacity = 1.6-2.0 g/denier (dry); 0.5 g/denier (wet ); Density = 1.779 gm/cc

Aliphatic hydrocarbon

== Description ==
One of two major classifications of hydrocarbon compounds. The other classification is aromatic hydrocarbon. Aliphatic hydrocarbons contain carbon atoms, and corresponding hydrogens, arranged in straight or branched chains. Starting with methane (CH4), aliphatic hydrocarbons increase in chain length and complexity with the addition of each carbon atom. Many aliphatic compounds are derived from petroleum distillates. Aliphatic hydrocarbons subgroups are: 
1) paraffins or alkanes (CnH2n+2): saturated hydrocarbons like propane or hexane.
2) olefins or alkenes (CnH2n): unsaturated hydrocarbons having one or more double bonds, such as ethylene or propylene,
3) acetylenes or alkynes (CnH2n-2): unsaturated hydrocarbons having one or more triple bonds, such as acetylene or allylene,
4) alicyclic: unsaturated hydrocarbon rings (not always included).

Alizarin, natural

== Description ==
Natural alizarin is a red colorant extracted along with purpurin from the roots of the madder plant, Rubia tinctorum L.. The chemical name for alizarin is 1,2-dihydroxyanthraquinone. It has been used as a dye and pigment since ancient times. The colorant was first isolated in 1862 by Colin and Robiquet in France. The synthetic form of alizarin was first made in 1868 by German chemists Carl Graebe and Carl Lieberman, from anthracene. The natural colorant was no longer used as a textile dye after the commercial introduction of the synthetic alizarin in 1871.
