Sodium dipropionate

Sodium dipropionate (CAS 63785-15-9), also known as sodium propionate, is the sodium salt of propionic acid used as an antimicrobial preservative and pH buffer in food, feed, and pharmaceutical manufacturing.

Where is Sodium dipropionate used?

• Baked goods, tortillas and packaged bread: controls mold and rope-forming bacteria
• Animal feed: suppresses fungal contamination in grain and compound feeds during storage and transit
• Pharmaceuticals: buffering agent and mild preservative in topical preparations and oral solid dosage forms
• Dairy products and processed meats: secondary hurdle against spoilage organisms
• It inhibits mold and bacterial growth in finished products and during processing, extending shelf life without synthetic preservative blends.

Commercial specifications

• Packaging from 25 kg bags to bulk quantities for industrial-scale procurement
