Description:

We, Fengchen Group, have both Sodium Metabisulfite, Sodium Metabisulphite Food Grade and Tech Grade.  Sodium Metabisulfite is soluble in water (when 20°C, 54g/lOOml water; when lOO°C,81.7g/lOOml water), acidic aqueous solution. Soluble in glycerine,slightly soluble in ethanol. Moisture easily decomposed, exposed in the air easily oxidized into sulfate. Exposure to emit sulfur dioxide and acid generated the corresponding salts. Heated to 150°C decomposition. Sodium Metabisulfite or Sodium Metabisulphite is an inorganic compound, which is composed of sodium, sulfur and oxygen. It typically comes in a white, or yellowish-white crystalline powder. Sodium Metabisulphite easily dissolves in water, which leaves that familiar sulfur (rotten egg) smell. Sodium Metabisulfite can be used as food preservative in food industry.

As a professional China Sodium Metabisulfite, Sodium Metabisulphite supplier and Manufacturer, FENGCHEN GROUP CO., LTD has been supplying and exporting Sodium Metabisulfite, Sodium Metabisulphite from China for almost 10 years. 

----------------------------------------

Sodium Metabisulfite, Sodium Metabisulphite is an inorganic salt used as a disinfectant and preservative agent in cosmetics and personal care commodities. It is also considered a reducing agent which donates hydrogen molecules to other substances in cosmetics and personal care comodities. Sodium Metabisulfite, Sodium Metabisulphite could also sometimes works as an antioxidant, with the function of preventing or slowing deterioration of formulas caused by chemical reactions with oxygen. Sodium Metabisulfite, Sodium Metabisulphite is considered to be an ingredient mainly in hair care commodities, like formulas for permanent waves, hair bleaches, hair dyes, colors and tints, and also in some bath and skin care products, etc.

 

Sodium Metabisulfite, Sodium Metabisulphite is FDA approved and has received its Generally Recognized as Safe (GRAS) rating. By the way, Sodium Metabisulfite, Sodium Metabisulphite is also CIR approved for use in cosmetic industry.

 

Safety Measures/Side Effects:

According to the Cosmetics Database, Sodium Metabisulfite, Sodium Metabisulphite is known as a moderate hazard ingredient, due to concerns regarding cancer, developmental and reproductive toxicity, immunotoxicity, irritation and organ system toxicity, with lesser concerns regarding neurotoxicity. Many companies and institute classifies Sodium Metabisulfite, Sodium Metabisulphite as a human immune and respiratory toxicant, and other organizations have classified Sodium Metabisulfite, Sodium Metabisulphite as an irritant and "as expected to be toxic or harmful."

 

According to many researches, undiluted Sodium Metabisulfite, Sodium Metabisulphite was not found to be an irritant to rabbits following occlusive exposures. However, at the concentration of 50%, it was irritating to guinea pigs following repeated exposure. This is a concentration that would not be found in cosmetics, hair, or personal care commodities. Sodium Metabisulfite, Sodium Metabisulphite was also found to be negative in mutagenicity studies, and there is not a concern regarding penetration or contamination because "Skin penetration would be low due to the highly charged nature of these particles and any sulfite that did penetrate would be converted to sulfate by the enzyme sulfate oxidase." It is finally reached a conclusion that Sodium Metabisulfite, Sodium Metabisulphite is a safe ingredient in cosmetics and personal care products.

 

It is worth noting that the MSDS for Sodium Metabisulfite, Sodium Metabisulphite labels it as "Hazardous in case of skin contact (irritant), of ingestion, of inhalation. Slightly hazardous in case of skin contact (permeator), of eye contact (irritant)" and that it "may be toxic to upper respiratory tract, skin, eyes." However, this is in higher, undiluted concentrations than found in cosmetics and personal care products, and is rather related to occupational exposures.

--------------------------------------------

Dangers of Sodium Metabisulfite, Sodium Metabisulphite:

Sodium Metabisulfite, Sodium Metabisulphite preserves food and is used extensively in commercial wine making. It is a bleaching agent in the textile, pulp and paper industries. Sodium Metabisulfite, Sodium Metabisulphite is also used in the chemical, pharmaceutical, film and photographic industries, and even in water and sewage treatment plants. However, pure or high concentration of Sodium Metabisulfite, Sodium Metabisulphite can be quite dangerous.

Inhalation of Sodium Metabisulfite, Sodium Metabisulphite will irritate respiratory tract, causing breathing problems. Symptoms like coughing and shortness of breath may occur. In some individuals, Sodium Metabisulfite, Sodium Metabisulphite may end up in an allergic, asthma-type reaction, which should go to the hospital for personal care immediately.

 

If get Ingestion accidently:

Ingesting pure Sodium Metabisulfite, Sodium Metabisulphite will also irritate the gastrointestinal system because it may react with acid in stomach by releasing sulfurous acid. Ingesting high amounts of Sodium Metabisulfite, Sodium Metabisulphite may cause nausea, vomiting, diarrhea, abdominal pains, circulatory disturbance and central nervous system depression.

 

Skin Contact:

Skin irritations may happen if directly exposed to high percent of Sodium Metabisulfite, Sodium Metabisulphite. When placed in direct contact, pure sodium metabisulfite can irritate skin causing redness, itching and pain.

 

Eye Contact:

Sodium Metabisulfite, Sodium Metabisulphite may also irritate our eyes.

Similar to skin irritation, direct contact of Sodium Metabisulfite, Sodium Metabisulphite with your eyes can cause irritation, pain, stinging, tearing, redness, swelling, corneal damage and blindness. These effects may be irreversible.

 

Allergic Reactions

Sodium Metabisulfite, Sodium Metabisulphite can cause allergic reactions.

It can cause extreme allergic reactions in certain sulfite-sensitive individuals, resulting in broncho constriction, shortness of breath, wheezing, coughing, gastrointestinal disturbances, rapid swelling of the skin, flushing, tingling sensations and shock.

-------------------------------------------

Usage and applications:

1. Pharmaceutical industry:

Sodium Metabisulfite is used in the the production of chloroform, benzene, styrene sulfone, and formaldehyde, etc.

2. Rubber industry: Sodium Metabisulphite Tech Grade is used as a coagulant.

3. Bleached cotton printing and dyeing industry: Sodium Metabisulfite as the dechlorination agent, cotton scouring agent. Leather tanning industry for processing, make the leather soft, plump, tough, waterproof, bending, wear and other properties.

4. The chemical industry: Sodium Metabisulfite can also be used to produce vanillin hydroxyl, hydroxylamine hydrochloride, etc.

5. The food industry: Sodium Metabisulfite Food Grade can be used as a bleaching agent, preservatives, leavening agent anti-oxidant, color agents and the insurance agent.

By the way, it may sometimes be a wine preservative.
