Purox® S Grains Sodium Benzoate

Logo for Purox S Grains Pure Grade Sodium Benzoate

The highest purity sodium benzoate available worldwide.

Low impurity levels give Purox S sodium benzoate an excellent taste and odor profile, making it the right choice for the most demanding end-product requirements. It has a long history of use as a globally trusted, nature identical preservative used to safely and effectively inhibit microbial growth in foods, beverages, cosmetics, toiletries, and pharmaceuticals up to pH 6.5. Purox S is an FDA GRAS food additive, approved for use as an antimicrobial agent, flavoring agent, and adjuvant (21 CFR § 184.1733).

In addition to its exceptional purity, Purox S offers outstanding physical properties for consistently high performance in handling, production and packaging processes. Thanks to the unique shaping process, Purox S has almost perfectly round particles with a narrow particle size distribution. The result of this tailor-made particle size distribution is an optimal combination of low dust content, high flow and excellent dissolution properties.

Safe & Effective Preservation Applications:

In personal care, Purox S is a green-label alternative to preservatives under scrutiny: sensitizers such as isothiazolinones (BIT, MIT, MCIT), irritants, parabens, and formaldehyde releasers. It is listed for use under ECOCERT COSMOS, EU Ecolabel, and Nordic Swan. It is often used with Kalama Benzyl Alcohol NF/FCC to leverage the ingredients’ natural antimicrobial synergy.

Common food and beverage applications include: fruit juices and salads, jellies, dressings and sauces, low-alcohol beverages and non-alcoholic beer.
