* Compared with chlorine bleaching chemicals that have contaminations on the environment, sodium percarbonate is an environmentally friendly chemical which decomposes into oxygen, water and natural soda ash when in contact with hydrous media.

* Sodium percarbonate is increasingly being the substitute for sodium perborate in detergent formulations due to its lower dissolving temperature in water, as well as the characteristic of no contamination on soil, as sodium perborate is made of borax which is found to have negative impact on the soil quality.

* Detergent or bleach compositions formulated with sodium percarbonate have an strong stain removal capability. It is very effective as a laundry presoak for heavily stained articles. It is color safe. It brightens colors and prevent fabric form become yellowed or darkened.

* Sodium percarbonate is effective as a disinfectant on both bacteria and virus. It's an excellent ingredient in personal care and home care formulations for hygiene.

* For its environmental advantages, sodium percarbonate is a good oxygen release chemical for agricultural and aquicultural applications.

Sodium percrabonate has a wide range of applications in various solid detergent products and all fabric bleaches. We may also find its usages in oxygen release compositions, personal care formulations, disinfectants, food bleaches, pulp and paper bleaches and textile bleaches, etc.
 

• Sodium percarbonate (or sodium carbonate peroxyhydrate) is an addition compound of sodium carbonate and hydrogen peroxide. When dissolved into water, its releases H₂O₂ and soda ash (sodium carbonate).
• The type of reaction shown as follows： 2Na₂CO₃.3H₂O₂ → 2Na₂CO₃+ 3H₂O₂ 
• The pH of the resulting solution is typically alkaline, which activates the H₂O₂ for bleaching. The dry powder contains about 30% w/w H₂O₂. 

Potassium monopersulfate offers a distinct advantage over less soluble, dry oxidants such as sodium perborate, particularly at relatively low temperatures. At the preferred proportions of one part sodium bromide to two parts sodium chloride by weight, optimum leaching values are obtained from the minus 250 mesh precious-metal-bearing ores at pH values from 3.2 to 3.6 and oxidation-reduction potential values from +750 to +850 millivolts. Bromine and chlorine are liberated, and the chlorine synergistically oxidizes the precious metal complexes enabling up to 98% of the precious metal to be extracted in the form of water soluble metal bromides.

Below is an example illustrating a process using potassium monopersulfate as oxidant：

First, add 500 gallons of water to a 1000 gallon capacity tank to which was also added 2000 pounds of precious-metal- bearing ore having a particle size reduced to minus 250 mesh. The ore had been assayed by atomic absorption, emission spectroscopy and fire assay and found to contain 5.8 ounces of gold, 13.2 ounces silver, 0.41 ounce platinum and 1.54 ounce rhodium per ton.The resultant slurry was stirred and 40 pounds of sodium bromide (97% technical grade) and 80 pounds sodium chloride (technical grade) were slowly added and the resultant slurry was stirred for 30 minutes, after which 0.25 pound increments of potassium monopersulfate were added, while the oxidation/reduction potential was monitored. The addition of potassium persulfate was continued until the potential reached 800 millivolts and the pH between 3.2 and 3.6. After the addition of 1.5 pounds of potassium monopersulfate the oxidation/reduction potential increased to +900 millivolts, and hydrochloric acid was added to reduce the potential to +810 millivolts. The slurry was stirred for five hours, and monitored every 30 minutes to determine its oxidation/reduction potential and pH. Potassium persulfate and hydrochloric acid were added in slight amounts as necessary to maintain the potential at 800 plus or minus 50 millivolts, and the pH between 3.2 and 3.6. After five hours, the slurry was filtered and the filtrate was pumped to a 750 gallon holding tank equipped with a stirrer. The precious metals in the filtrate were recovered by adding one gallon of an aqueous solution of 6 weight percent sodium borohydride and 20 weight percent sodium hydroxide was added. The oxidation/reduction potential of the liquid was adjusted to and maintained at -600 millivolts, plus or minus 50 millivolts and the pH of the liquid was maintained at 8.3 to 8.7 by the addition of sodium borohydride and hydrochloric acid. After two hours of stirring, the liquid was filtered to recover the precipitate of precious metals. The filtrate was reconstituted for reuse. The filtered solids were dried and purified to determine that the recovery, per ton of ore, was: 5.64 ounces of gold, 12.6 ounces of silver, 0.38 ounces of platinum, and 1.48 ounces of rhodium.

Keep in a cool, dry, well-ventilated place. Keep tightly closed before use. Store away from incompatible substance. Keep away from fire and heat source. Pay attention to moisture and rain. Seal packaging and store separately, do not mix with reducing agents, acids or easy (can be) burning materials.

The service life of frying oil depends on the sales volume, product mix, and fry station management practices. The oil could be dark, smoking, foaming, or has a bad smell after 3 days without Kchoring^®. Therefore, it is time to change the oil.

To those who use the Kchoring^® filter daily, the oil’s service life could be extended by at least 30 - 50%, and the cost saving by up to 50%. The decision to change oil depends on finished food quality standards and sensory evaluation of Color, flavor, taste, appearance texture, etc. Join us now, and enjoy an annual bonus with Kchoring^®.

If the oil is not changed in time, it will cause excessive benzopyrene, excessive acid value, excessive aflatoxin, and extremely high peroxide values. During frying, the oil will surround and penetrate the food and become part of the food. As the frying oil breaks down, dissolved impurities will penetrate the food, affecting its taste, texture, and appearance.

Using Kchoring^® every day can safely remove dissolved impurities in the oil and extend the oil’s service life. Only the fresh, clean frying oil can provide customers with consistently safe, delicious, crispy, and golden fried foods. If daily filtration is not carried out, the service life of the frying oil will be reduced. To reduce the cost of frying oil, maintain the quality and taste of food, and satisfy customers - use Kchoring^® every day.

Free fatty acids (FFA) or “Acid value” is an important parameter used in evaluating the quality of oil. FFA are molecules that lower the surface tension of oils, allowing batter and breading to soak up more oil. TPM refers to the extent of oxidative thermal degradation of frying oil and is one of the objective criteria for assessing the deterioration of cooking oil, which affects the taste and temptation of fried foods.

We are the first drafting unit of the national standard for Food-grade Magnesium Silicate, which is the main ingredient of oil filter powder. Kchoring^® can effectively eliminate FFAs, TPMs, colors, off-flavors, and odors, which greatly slow down the formation of these molecules, allowing the oil to last longer and making fried foods taste more crisp.

Yes. Oil degradation is pretty common with all edible frying oils, but rest assured that we not only have extensive experience in edible oil purification but also provide a one-on-one customized solution. Kchoring^® is effective on all types of oil, including the new zero trans-fat oils.

Sodium percarbonate is known for being non-corrosive and safe to use on most indoor or outdoor surfaces except finished and unfinished wood surfaces. So it is important to note that sodium percarbonate should not be use on hardwood floors.

Sodium percarbonate should be stored in a sealed container at room temperature. This chemical, similar to solid hydrogen peroxide, can be irritating and corrosive to the skin and especially to the eyes. Therefore, it is crucial to keep it out of the reach of children. Ingestion should be strictly avoided at all concentrations, and we recommend using gloves when handling it for cleaning applications. Sodium percarbonate is known to be human-safe and biodegradable, making it generally safe for disposal in the trash. However, we advise checking with local regulations to ensure proper disposal methods.

Yes and no.
Since sodium percarbonate is a natural bleaching agent, it may discolor your clothes if left too long or used undiluted or in high concentrations. However, when diluted according to package directions, JHY sodium percarbonate can be safely used on white or colored clothing with minimal risk of discoloration. We recommend conducting a small patch test to check how your clothing reacts before full use.

Sodium percarbonate may begin to decompose after one year. However, this does not necessarily mean that it won't work or is dangerous to use. It may simply lose some effectiveness after one year.
