Potassium Metabisulfite

Potassium metabisulfite, K₂S₂O₅, also known as potassium pyrosulfite, is a white crystalline powder with a pungent odour. It is mainly used as an antioxidant or chemical sterilant. As a disulfite, it is chemically very similar to sodium metabisulfite, with which it is sometimes used interchangeably.

are safe as used in cosmetic formulations.

Is sodium metabisulfite safe in skin care?

In 2013 the Cosmetic Ingredient Review Expert Panel deemed sodium metabisulfite safe as used in cosmetic formulations (their report looked at skin care products using less than 1% concentrations). Its safety status was reaffirmed in 2020.

What does sodium metabisulfite do for the skin?

Sodium metabisulfite is an antioxidant-based preservative that is used in cosmetics and skincare products to prevent contamination by bacteria and mold and to extend the shelf-life of products.

Is sodium sulfite good for skin?

the good:Sodium Sulfite preserves formulations, preventing contamination by the environment and use. the not so good:It can cause some irritation and allergy that has been linked to sodium sulfite in some skin types, particularly sensitive skin.

What is the difference between sodium metabisulfite and sodium metabisulfite?

The key difference between sodium bisulfite and sodium metabisulfite is that the sodium bisulfite has only one sulfur atom and three oxygens, and the bisulfite anion is monovalent whereas, the sodium metabisulfite has two sulfur atoms, five oxygens, and the anion is divalent.

What is another name for sodium metabisulfite?

Sodium metabisulfite, also known as sodium pyrosulfite, is an inorganic compound with the chemical formula Na2S2O5. The IUPAC spelling of the compound is sodium metabisulphite or sodium pyrosulphite.

What happens when you mix sodium metabisulfite with water?

It is known that sodium metabisulfite can react with acids and water, releasing toxic sulfur dioxide (SO2) gas.

Is metabisulfite harmful?

* Sodium Metabisulfite may cause an asthma-like allergy. Future exposure can cause asthma attacks with shortness of breath, wheezing, cough, and/or chest tightness. * Sodium Metabisulfite can irritate the lungs. Repeated exposure may cause bronchitis to develop with cough, phlegm, and/or shortness of breath.

What are the features of contact allergy to sodium metabisulphite? Sensitised individuals will develop contact dermatitis on exposure. The most common primary site of the allergic reaction are the hands and face. The rash can be red, swollen, and vesicles or blisters may develop.

Is metabisulphite an allergen?

Conclusions: Sodium metabisulfite is an unusual but not infrequent contact allergen whose chemistry suggests a previously unrecognized protein modification mechanism involving nucleophilic attack by sulfite di-anions on target electrophilic centres in skin proteins.

Is propylene glycol good for skin?

The bottom line. You'll find propylene glycol in plenty of skin care and beauty products, especially products designed to moisturize. This ingredient is generally considered safe, even beneficial — though you might want to try it with caution if you have sensitive skin or eczema.

What are the worst preservatives?

How do you dilute sodium metabisulfite?

Weigh out 2.5 g of sodium metabisulfite. In a 150-ml acid-washed beaker, dissolve the sample in 100 ml of deionized distilled water. Under a hood, acidify the solution with concentrated HNO₃ to a pH of less than 2. Gently heat the solution to reduce the volume below 100 ml, making certain that it does not boil.
