This property makes it valuable in certain applications, particularly those where its moisture-absorbing capabilities are useful.

Production et source

Synthesis Methods

Sodium formate can be synthesized using a method that involves neutralizing formic acid with sodium hydroxide. In this chemical reaction, formic acid (HCOOH) reacts with sodium hydroxide (NaOH) to produce sodium formate (NaHCOO) and water (H2O). This process is commonly employed in industrial production to create sodium formate, which has various practical applications across different industries.

Natural Sources

While sodium formate is primarily produced through synthetic methods, it can also be found in certain natural sources. One notable natural source of sodium formate is the secretions of certain species of ants. Some ants produce formic acid (HCOOH) as a part of their defensive mechanisms, and over time, this formic acid can react with minerals in the environment to form sodium formate.

It’s important to note, however, that the industrial-scale production of sodium formate far exceeds the quantities derived from these natural sources. Synthetic production methods are more efficient and practical for meeting the demand for this versatile chemical compound in various industries.


Sodium formate boasts a wide range of applications across several industries. Some of its notable uses include:

Agent de dégivrage

Sodium formate is commonly employed as a deicing agent, especially in regions with cold climates. Its ability to melt ice and snow makes it valuable in the winter maintenance of roadways and runways. When spread on icy surfaces, sodium formate works by lowering the freezing point of water, causing ice and snow to melt. This property helps ensure safer transportation and reduces the risk of accidents during winter weather conditions. Sodium formate’s effectiveness as a deicing agent has made it a go-to solution for managing snow and ice accumulation in various transportation infrastructure applications.

Drilling Fluids

In the oil and gas industry, sodium formate plays a crucial role as an additive in drilling fluids. Drilling fluids, also known as drilling mud, are essential in the drilling process for various purposes, including lubricating the drill bit, cooling and cleaning the drill string, and stabilizing the wellbore.

Sodium formate is used in drilling fluids as a shale stabilizer. Shale, a type of sedimentary rock, can be prone to swelling and destabilization when it comes into contact with water-based drilling fluids. Sodium formate mitigates this issue by helping to prevent shale from swelling and disintegrating, thus maintaining the stability of the wellbore.

The addition of sodium formate to drilling fluids is a valuable practice that contributes to the overall success of drilling operations in the oil and gas industry. It helps ensure the structural integrity of the wellbore, minimizing the risk of wellbore instability and related challenges during the drilling process.

Leather Tanning

In the leather industry, sodium formate is utilized as an essential component in the process of tanning. Tanning is the method by which animal hides, typically from cows, sheep, or goats, are treated to produce durable and supple leather materials. Sodium formate plays a significant role in this process due to its unique properties.

During tanning, sodium formate is used as a tanning agent, helping to transform raw animal hides into leather. It serves several important functions:

  1. Preservation: Sodium formate helps in preserving the hides, preventing decay and the growth of bacteria. This preservation process is crucial for turning raw animal hides into a material that won’t deteriorate over time.
  2. Softening: Sodium formate also contributes to the softening of the leather. It makes the leather more flexible and comfortable to work with, resulting in high-quality leather products such as shoes, bags, and garments.
  3. Stabilization: By stabilizing the collagen fibers in the animal hides, sodium formate ensures that the leather remains structurally sound and maintains its shape and texture.

  1. Inhibition of Microbial Growth: Sodium formate acts as an effective antimicrobial agent. It inhibits the growth of bacteria, molds, and yeasts in food products. By preventing or slowing down microbial proliferation, it helps maintain the freshness and safety of various food items.
  2. pH Control: Sodium formate can be used to control and stabilize the pH levels of food products. Maintaining the correct pH is crucial in preventing spoilage and ensuring that the product remains safe to consume.
  3. Enhanced Shelf Life: By hindering the development of spoilage microorganisms and maintaining the quality of food products, sodium formate contributes to extending their shelf life. This results in reduced food waste and a longer window for consumers to enjoy the product.

Impact environnemental


Sodium formate is known for its biodegradability, which is an important characteristic in terms of its environmental impact. Biodegradability means that the compound can break down naturally and be absorbed by the environment without causing long-term harm. Sodium formate decomposes into simpler and environmentally benign substances, primarily carbon dioxide and water, when it is exposed to natural conditions.

This property makes sodium formate a more eco-friendly choice compared to some chemical alternatives that might persist in the environment for extended periods, potentially causing pollution or ecological damage. As a biodegradable substance, sodium formate contributes to reducing the environmental footprint associated with its use in various applications.

Eco-Friendly Alternatives

Several eco-friendly alternatives are being developed and considered in industries where sodium formate is used, such as deicing agents, drilling fluids, and food preservation. These alternatives aim to minimize the ecological impact and address specific environmental concerns. Some examples of these alternatives include:

  1. Organic Deicers: Environmentally friendly deicing agents, often made from organic materials like beet juice or corn-based products, are becoming popular alternatives to traditional salt-based deicers. They are less harmful to vegetation and aquatic ecosystems.
  2. Green Drilling Fluids: In the oil and gas industry, there is a growing interest in green drilling fluids that have reduced environmental impact. These fluids may use biodegradable additives and have improved recycling and waste management processes.
