Bio-based Succinic acid CAS 110-15-6

Introduction to Bio-based Succinic Acid

Bio-based Succinic Acid is a four-carbon dicarboxylic acid manufactured through industrial microbial fermentation using renewable carbohydrate feedstocks, offering a sustainable alternative to petroleum-derived succinic acid. It appears as white crystalline powder at room temperature, soluble in water and alcohols, and features two reactive carboxylic acid groups that support a wide range of condensation, esterification and polymerization reactions.

With over 99% bio-based carbon content, it delivers identical chemical performance to fossil-based grades while significantly reducing environmental impact. It is a key platform chemical for the bio-economy, serving as a precursor to numerous downstream green chemicals and biodegradable materials.

Bio-based Succinic Acid Chemical & Physical Properties

Applications of Bio-based Succinic Acid

Biodegradable polymer synthesis: Serves as the core monomer for producing polybutylene succinate (PBS), polybutylene succinate adipate (PBSA) and other bio-based polyesters. These materials are fully biodegradable in soil and marine environments, replacing conventional plastics in packaging, disposable goods and agricultural films.

Food and beverage additives: Used as an acidulant, flavor enhancer and buffering agent in food and drink formulations. It provides mild, sustained tartness and acts as a sequestrant to stabilize color, flavor and shelf life in processed foods, beverages and confectionery.

Pharmaceutical and cosmetic intermediates: Functions as a raw material for synthesizing active pharmaceutical ingredients, excipients and cosmetic buffers. It also acts as a pH adjuster and chelating agent in personal care formulations, with good skin compatibility.

Industrial green chemicals: Converted into bio-based solvents, plasticizers, lubricants and corrosion inhibitors. It replaces petroleum-derived diacids in alkyd resins, hot melt adhesives and water treatment formulations, supporting low-carbon industrial transition.

Storage & Safety Precautions for Bio-based Succinic Acid

• Store in tightly sealed moisture-resistant packaging in a cool, dry warehouse. The material is slightly hygroscopic; exposure to high humidity causes caking and reduced flowability. Keep away from strong oxidizers and bases.
• Wear safety goggles, dust masks and nitrile gloves during bulk powder handling. Avoid inhalation of dust, which may cause mild irritation to the respiratory tract and eyes. Rinse with water in case of contact.
• Non-flammable and low toxicity. Store separately from food and feed materials to prevent cross-contamination. Process waste according to local environmental regulations.

Bio-based Succinic Acid FAQ

Q: What is the difference between bio-based and petroleum-based succinic acid?

A: Bio-based succinic acid is produced from renewable plant feedstocks via fermentation, with over 99% bio-based carbon and a lower carbon footprint. It has identical chemical purity and reactivity as petroleum-derived grades.

Q: What is the largest application of bio-based succinic acid?

A: Its primary use is as a monomer for biodegradable polyesters like PBS and PBSA, which replace conventional plastics in packaging, disposable products and agricultural applications.

Q: What storage conditions does bio-based succinic acid require?

A: Store sealed in a cool, dry place. It is slightly hygroscopic, so moisture protection prevents caking and maintains consistent flowability and purity.
