Purox B Food/Pharma - a cost effective preservative -

With the introduction of Purox B Food/ Pharma ultra pure grade benzoic acid, DSM has realized a breakthrough in the market for preservatives. Purox B Food/ Pharma can be directly used as a preservative in food, cosmetic and pharmaceutical applications.

Benzoic acid and its sodium and potassium salts have been extensively used for many years as a preservative to control microbial growth, for instance of yeast, bacteria, mould and fungi, in various applications. The salts are more soluble in water than benzoic acid and are preferred as preservatives for use in water-based systems.

In applications where solubility and speed of dissolution are not important Purox B Food/ Pharma offers the opportunity to replace the benzoate salts selectively by ultra pure benzoic acid.

Purox B Food/ Pharma can be used in a wide range of products and can even replace more expensive acids currently used.

For example . . use in :

• Bakery products
• Cosmetic and toiletry
• Hot pack processing
• Toothpastes and mouthwashes
• Silage
• Fish

A guaranteed benzoic acid content of at least 99.98 % is possible by the use of an innovative purification technology. The new Purox B Food/Pharma stands out because of its low impurity content; it has earned a classification as user friendly.

Next to the purity, this ultra pure grade benzoic acid meets the requirements of E210, European Pharmacopeia, US Pharmacopeia/National Formulary, Food Chemical Codex and Japanese Pharmacopeia.
