Succinic Acid: Where Does it Shine From Amber to Agriculture?

0 34

In the realm of organic chemistry, certain compounds hold a pivotal place due to their diverse applications and profound impact on various industries. One such compound that commands attention is succinic acid. This dicarboxylic acid, with its unique structure and versatile properties, has found its way into the heart of pharmaceuticals, agriculture, and even bio-based materials. Let’s explore the intricacies of succinic acid, unraveling its molecular secrets and exploring the myriad ways in which it contributes to scientific innovation and industrial progress.

What is Succinic Acid?

Succinic acid, a naturally occurring dicarboxylic acid, is produced by living cells through anaerobic digestion of various carbon sources. It is a colorless and odorless solid with a strong acidic flavor. When dissolved in water, this acid easily dissociates to form its conjugate base, succinate. It is important to note that it is a diprotic acid, undergoing two consecutive deprotonation reactions.

The pKa values for these reactions are 4.3 and 5.6, correspondingly. The resulting anions are colorless and can be obtained as salts, such as Na(CH2)2(CO2H)(CO2) and Na2(CH2)2(CO2)2. In living organisms, succinate, rather than succinic acid, is predominant. Identified as a radical group, it is termed a succinyl group. Comparable to other simple mono- and dicarboxylic acids, it is generally non-hazardous but may cause irritation to the skin and eyes.

The Department of Energy in the United States has identified succinic acid (SA) as one of the leading bio-based components achievable through microorganisms, ranking it among the top 12 in this category.

Benefits of Succinic Acid

Succinic acid has numerous advantages, especially in the fields of skincare and specific medicinal uses. Let’s take a closer look at some of its benefits:

  • Anti-Inflammatory Properties: It is renowned for its ability to alleviate inflammation, making it highly effective in diminishing skin redness, irritation, and swelling. This characteristic can be especially advantageous for individuals who experience acne symptoms or other skin conditions marked by inflammation.
  • Antimicrobial Abilities: It has antimicrobial qualities, which can effectively hinder the proliferation of bacteria on the skin. This attribute proves beneficial in treating acne outbreaks and counteracting the influence of bacteria and yeast that could potentially exacerbate skin problems.
  • Antioxidant Benefits: Succinic Acid provides antioxidant advantages, assisting in safeguarding the skin from harm caused by free radicals. This aligns with its ability to promote overall skin well-being and enhance its resilience against external stressors.
  • Skin Hydration and Soothing: It has gained popularity because of its exceptional moisturizing and calming attributes, which make it an invaluable inclusion in skincare products. When combined with other hydrating components, it aids in maintaining optimal skin hydration and ensuring overall skin well-being.
  • Acne Management: It has proven to be a viable solution for alleviating acne symptoms without inducing irritation. Its capacity to effectively eliminate acne and deter future breakouts, along with its anti-inflammatory and antimicrobial attributes, renders it a promising component for the management of acne.

Applications of Succinic Acid Across Industries

Succinic acid, being a versatile dicarboxylic acid, is widely used in diverse industries due to its distinctive characteristics. Its applications span across various sectors, and some notable ones are:


Succinic acid plays a fundamental role in the creation of medicines and active pharmaceutical components (APIs) as a precursor. It serves as a foundational element in the manufacturing of medications, which greatly contributes to the overall production process within the pharmaceutical sector.


It is utilized in agriculture as a stimulant for plant growth. Its capacity to improve the absorption of nutrients and encourage the growth of plants makes it valuable in specific formulations utilized for crop production.

Biodegradable Polymers:

It plays a crucial role in the production of biodegradable polymers. It is utilized in the synthesis of polybutylene succinate (PBS), a biodegradable plastic that serves as an eco-friendly alternative to traditional petroleum-based plastics.

Cosmetics and Personal Care Products:

The cosmetic industry incorporates this acid into formulations for personal care products. It can function as a pH adjuster and is sometimes used in skincare products due to its mild and skin-friendly properties.

Food and Beverage:

It is recognized as a food additive and acidity regulator. It is used in some food and beverage products to adjust acidity levels and enhance flavor profiles.

Wrapping it Up

The significance of succinic acid emerges as a thread weaving through the fabric of multiple industries. From its role as a platform chemical to its applications in sustainable practices, it stands tall as a testament to the wonders of organic chemistry. As research continues to unlock new possibilities, the future holds promise for this remarkable compound to play an even more influential role in shaping the landscape of science and industry. This acid, with its molecular prowess, remains a compelling force driving innovation and sustainability in our ever-evolving world.
