Zinc Benzoate Introduction


Zinc Benzoate is the Zinc salt of Benzoic acid. While it can be used as a food preservative like the more commonly used Sodium Benzoate, this rare Benzoic salt is primarily used as an industrial additive in the PVC and coating industries. There are also feed additive manufacturers exploring its used as a substitute of Zinc Oxide in swine feeds.

Uses of Zinc Benzoate


As a PVC Heat Stabilizer Ingredient

Zinc Benzoate can be used as an ingredient in PVC heat stabilizers designed for transparent and flexible/semi-rigid PVC materials.

Depending on the specific stabilizer formula, Zinc Benzoate makes up 1% – 4% of the total stabilizer mixture. Although stabilizer manufacturers might have different considerations when adding Zinc Benzoate to their products, this ingredient primarily mitigates PVC’s whitening effects caused by prolonged exposure to sunlight and submersion in water.

As a Feed Additive Ingredient

In face of the coming 2022 ban of Zinc Oxide in EU and its restricted uses world wide, the feed additive industry has been looking for an alternative chemical to both serve as an animal Zinc supplement and to prevent post-weaning diarrhoea among piglets.

Zinc Benzoate has been actively considered by some of the leading companies in the feed additive industry as an alternative to Zinc Oxide.

As an Antimicrobial Agent in Pigment Coating

Zinc Benzoate serves as an antimicrobial agent in pigment coatings.

Due to its relatively high solubility, which may not always be desirable in coatings, Zinc Benzoate is usually used in protected coatings with slow-releasing mechanisms.

As a Food Preservative in Substitution of Sodium Benzoate

Zinc Benzoate can be used as a substitute of Sodium Benzoate when there is a sensitive cap on the food’s Sodium content. It has an antimicrobial mechanism similar to the more common Sodium Benzoate.
