POTASSIUM PROPIONATE = POTASSIUM PROPANOATE = PROPIONIC ACID POTASSIUM SALT

CAS Number: 327-62-8
EC Number: 206-323-5
MDL number: MFCD00045936

Potassium propionate is the potassium salt of propionic acid.
Potassium propanoate belongs to the class of organic compounds known as carboxylic acid salts.
These are ionic derivatives of carboxylic acid.
Potassium propanoate or potassium propionate has formula K(C2H5COO).
Potassium propionate's melting point is 410 °C.

Potassium propionate is the potassium salt of propanoic acid.
Potassium propionate is used as a food preservative and is represented by the food labeling E number E283 in Europe and by the INS number 283 in Australia and New Zealand.
Potassium propionate can be analyzed by this reverse phase (RP) HPLC method with simple conditions.
The mobile phase contains an acetonitrile (MeCN), water, and phosphoric acid.
For Mass-Spec (MS) compatible applications the phosphoric acid needs to be replaced with formic acid.

Smaller 3 µm particles columns available for fast UPLC applications.
This liquid chromatography method is scalable and can be used for isolation impurities in preparative separation.
Potassium propionate also suitable for pharmacokinetics.
Potassium salt of propionic acid, a natural acid present in small quantities in many foods, sometimes in high concentrations produced by bacteria in fermented foods, such as types of Swiss cheese.
Potassium propionate is also produced on a large scale by the bacteria in the large intestine.

USES and APPLICATIONS of POTASSIUM PROPIONATE:
-Potassium propionate is used as an antimicrobial agent in bread to prevent germination of some types of bacteria which causes sticky yellow patches to occur.
-Potassium propionate is very effective against molds and rope forming bacteria and is preferred in chemically leavened cakes, tortillas, pie fillings.
-Protects cosmetic products from microbial spoilage

-Potassium propionate 98% is a useful research chemical.
-Propionic acid and propionates are used as preservatives, mainly against fungi.
-Potassium salt of propionic acid, a natural acid present in small quantities in many foods, sometimes in high concentrations produced by bacteria in fermented foods, such as types of Swiss cheese.
-Potassium propionate is also produced on a large scale by the bacteria in the large intestine.

-Preservative:
Prevents and inhibits the growth of unwanted microorganisms which may be harmful.
Potassium propanoate or potassium propionate is the potassium salt of propanoic acid.
Potassium propanoate is used as a food preservative and is represented by the food labelling E number E283 in Europe.
The typical products are flour products, where Potassium propanoate is used as a mold inhibitor and a means of reducing the yeast content of bread.
In EU, Potassium propanoate is approved to use as a food additive.

-Use in cosmetics:
Preservatives protect cosmetic products from microbial spoilage and thus make an important contribution to consumer health. Preservatives are necessary, especially when a cosmetic product contains water.
Because microorganisms can settle and multiply in water.
-Propionic acid and propionates are used as preservatives, mainly against fungi.

-As a preservative in various cosmetic products.
-Cosmetics often contain not just one preservative, but a mix of several preservatives to act against different bacteria, yeasts or molds at the same time.
Each of these substances is independently tested to ensure it is safe and tolerable to use in a cosmetic product.
The manufacturers always use the lowest possible concentration in a product, so that optimal durability and carefree use are guaranteed.
