Fluorescent Whitening Agent (FWA)
It is a compound with a very high quantum efficiency, in the order of 1 million to 100,000 parts, which can effectively whiten natural or white substrates (such as textiles, paper, plastics, coatings). It can absorb the violet light with a wavelength of 340-380nm and emit blue light with a wavelength of 400-450nm, which can effectively make up for the yellowing caused by the blue light defect of white materials. It can improve the whiteness and brightness of the white material. The fluorescent whitening agent itself is colorless or light yellow (green) color, and is widely used in papermaking, textile, synthetic detergent, plastics, coatings and other industries at home and abroad. There are 15 basic structural types and nearly 400 chemical structures of fluorescent whitening agents that have been industrialized.

Sodium Carbonate
Inorganic compound soda ash, but classified as salt, not alkali. Sodium carbonate is a white powder, tasteless and odorless, easily soluble in water, aqueous solution is strongly alkaline, in humid air will absorb moisture clumps, part of the sodium bicarbonate. The preparation of sodium carbonate includes the joint alkali process, the ammonia alkali process, the Lubran process, etc., and it can also be processed and refined by trona.

Ammonium Bicarbonate
Ammonium bicarbonate is a white compound, granular, plate or columnar crystals, ammonia odor. Ammonium bicarbonate is a kind of carbonate, ammonium bicarbonate has ammonium ion in the chemical formula, is a kind of ammonium salt, and ammonium salt can not be put together with alkali, so ammonium bicarbonate should not be put together with sodium hydroxide or calcium hydroxide.

Sodium Bicarbonate
Inorganic compound, white crystalline powder, odorless, salty, soluble in water. It is slowly decomposed in humid air or hot air, producing carbon dioxide, which is completely decomposed when heated to 270 ° C. When exposed to acid, it breaks down strongly, producing carbon dioxide.
-
Sodium Sulfite
Sodium sulfite, white crystalline powder, soluble in water, insoluble in ethanol. Insoluble chlorine and ammonia are mainly used as artificial fiber stabilizer, fabric bleaching agent, photographic developer, dye bleaching deoxidizer, fragrance and dye reducing agent, lignin removal agent for paper making.
-
Sodium Hydrogen Sulfite
In fact, sodium bisulfite is not a true compound, but a mixture of salts that, when dissolved in water, produces a solution composed of sodium ions and sodium bisulfite ions. It comes in the form of white or yellow-white crystals with an odor of sulfur dioxide.

Acetic acid
It is an organic monic acid, the main component of vinegar. Pure anhydrous acetic acid (glacial acetic acid) is a colorless hygroscopic liquid, its aqueous solution is weakly acidic and corrosive, and it is strongly corrosive to metals.
-
Active Poly Sodium Metasilicate
It is an efficient, instant phosphorus free washing aid and an ideal substitute for 4A zeolite and sodium tripolyphosphate (STPP). Has been widely used in washing powder, detergent, printing and dyeing auxiliaries and textile auxiliaries and other industries.
-
Phosphoric acid
A common inorganic acid, phosphoric acid is not easy to volatilize, not easy to decompose, almost no oxidation, with acid commonness, is a ternary weak acid, its acidity is weaker than hydrochloric acid, sulfuric acid, nitric acid, but stronger than acetic acid, boric acid, etc. Phosphoric acid is easily deliquified in the air, and heat will lose water to get pyrophosphoric acid, and then further lose water to get metaphosphate.

Dodecylbenzenesulphonic acid (DBAS/LAS/LABS)
Dodecyl benzene is obtained by condensation of chloroalkyl or α-olefin with benzene. Dodecyl benzene is sulfonated with sulfur trioxide or fuming sulfuric acid. Light yellow to brown viscous liquid, soluble in water, hot when diluted with water. Slightly soluble in benzene, xylene, soluble in methanol, ethanol, propyl alcohol, ether and other organic solvents. It has the functions of emulsification, dispersion and decontamination.
