Potassium chlorate is a compound containing potassium, chlorine and oxygen, with the molecular formula KClO3. In pure form, it is a white crystalline substance. It is the most common chlorate in industrial use, and is usually present in well-stocked laboratories. It is used
as an oxidizing agent,
to prepare oxygen,
as a disinfectant,
in safety matches, and
in explosives and fireworks.

Safety
Potassium chlorate should be handled with care. It reacts vigorously, and in some cases spontaneously ignites or explodes, when mixed with many combustible materials. It will burn vigorously in combination with virtually any combustible material, even those which are considered to by only slightly flammable normally (including ordinary dust and lint).
Mixtures of potassium chlorate and a fuel can be ignited by contact with sulfuric acid and this reagent should be kept away from potassium chlorate. Sulfur should be avoided in pyrotechnic compositions containing potassium chlorate, as these mixtures are prone to spontaneous deflagration.
Most sulfur contains trace quantities of sulfur-containing acids, and these can cause spontaneous ignition - "Flowers of sulfur" or "sublimed sulfur", despite the overall high purity, contains significant amounts of sulfur acids. Also, mixtures of potassium chlorate with any compound with ignition promoting properties (ex. antimony(III) sulfide) are very dangerous to prepare, as they are extremely shock sensitive.

Dangerous Goods Class: 5.1
Uses: Sodium Percarbonate has a side range of applications in various cleaning products and detergent formulations including heavy duty laundry detergents, all fabric bleaches, wood deck bleaches, textile bleaches and carpet cleaners.
Other applications have been explored in personal care formulations, denture cleaners, pulp and paper bleaching process, and certain food bleaching applications, The product also has functions as disinfector for institutional and home applications, oxygen releasing agent in agreculture, waste water treatment chemical, first-aid oxygen generating agent, etc.

Percarbonate is used as an activated oxygen component in detergents, bleaches and cleaning agents. Due to the unsatisfactory storage stability of the uncoated sodium percarbonate in warm/moist surroundings and in the presence of certain detergent and cleaning agent components, percarbonate must be stabilized against the loss of active oxygen.
An essential principle of stabilization involves encasing the percarbonate particles in a coating of components having a stabilizing action.
Here comes the definition: the coated sodium percarbonate is the crystals coated with single or multiple layers of various substances in order to increase active oxygen stability and optimize storage and ensiling properties.

Coated sodium percarbonate is the more commonly commercialized peroxide compared with the uncoated type. But the uncoated product is still the preferred ingredient for simply mixing with enough quantity of soda ash and some surfactants to form the popular oxygen bleaches.

Thiourea dioxide is also called formamidine-sulfinic and is often abbreviated as TDO or TUD. Thiourea dioxide is a powdered stable compound, which dissolves in water and decomposes gradually to produce sulfoxylic acid through formamidine-sulfinic acid to exhibit a reducing action.
This reaction is promoted by the application of heat or in the presence of an alkali, and a strong reducing action is thereby exhibited. But, this reaction is slow, and particularly in an acidic to weakly alkaline region.

Thiourea dioxide (TDO) is a strong reductant which re-arranges under alkaline conditions to form formamidine sulphinic acid. This product is used in leather processing industry, paper, pulp and board industry, photographic industry, textile processing industry, bleaching and reducing agents. This product is also a component of decolorisation agents.
TDO has been very effective on a wide variety of pulp sources as a reductive bleaching aid in the pulp and paper industry. The application of TDO is crucial to achieve optimal brightness gain in the deinking process.

Uses:
Thiourea Dioxide is one new kind environmental-protection agent which is can be used as exchange of Sodium Hydrosulfite. It has good heat stability, high as reducibility, easy operation and transportation and storage convenient.
It widely applies to reduction dyes and sulfur dyes dyeing, wool and silk bleaching, disperse dyes reducing cleaning, dye vat cleaning and so on.
And also used in paper making industry as bleaching agent, deinking, waste paper deink, etc.
And then used to organic synthesis in synthetic fiber industry, additive of polythene sensitizer of photographical emulsion, noble metal recycling and separates, etc. There is no pollution during the operation.

a.500kg or 1000kg jumbo bags.
b.50kg fiber drums.
c.25kg or 50kg woven bags.
