Allura red ac is a red azo dye that goes by several names including: allura red, food red 17, c. I. 16035, fd&c red 40[1][2], 2-naphthalenesulfonic acid, 6-hydroxy-5-((2-methoxy-5-methyl-4-sulfophenyl)azo)-, disodium salt, and disodium 6-hydroxy-5-((2-methoxy-5-methyl-4-sulfophenyl)azo)-2-naphthalene-sulfonate. It is used as a food dye and has the e number e129. Allura red ac was originally introduced in the united states as a replacement for the use of amaranth as a food coloring.

Alkylbenzene sulfonic acid, as the raw material of detergent, is used to produce alkylbenzene sulfonic acid sodium (LAS), which has the performances of cleaning, wetting, foaming, emulsifying and dispersing, etc. The rate of biodegradation is more than 90%. The product is widely used for producing various detergents and emulsifiers, such as washing powder, detergent of dishware, detergent of light or hard dirt, cleaner of textile industry, dyeing assistant, degreaser of plating and leather making industry, and the deinking agent of paper-making industry, etc

Household detergents including laundry powders, laundry liquids, dishwashing liquids and other household cleaners. Industrial applications of wetting agent, emulsifier for agricultural herbicides and in polymerization.

Methanesulfonic acid is a colorless liquid with the chemical formula CH3SO3H. It is the simplest of the alkylsulfonic acids. Salts and esters of methanesulfonic acid are known as mesylates.

Prism-white crystals, dilute hydrochloric acid crystallization with two molecular crystal water. The temperature 90 ° c (hydrate) ,139-140 ° c (anhydrous). Both soluble in water and alcohol, ether-soluble.

p-Toluenesulfonic acid (PTSA) is an organic compound with the formula CH3C6H4SO3H. TsOH, as it is abbreviated, is a white solid that is soluble in water, alcohols, and other polar organic solvents. Most often, TsOH refers to the monohydrate, TsOH.H2O.

Sulfonic acid is a compound with general formula RSO2OH, where R is an aliphatic or aromatic hydrocarbon. It is a derivative of sulfuric acid (HOSO2OH) where an OH has been replaced by a carbon group or a compound where a hydrogen atom has been replaced by treatment with sulfuric acid; for example, benzene is converted to benzenesulfonic acid (water-soluble). Sulfonic acid has a sulfur atom bonded to a carbon atom of a hydrocarbon and bonded also to three oxygen atoms, one of which has been attached to a hydrogen atom.
