Is Cinnamic Acid Flammable? Discover the Shocking Truth!

Is Cinnamic Acid Flammable?

Cinnamic acid is a common organic compound that can be found in various plants such as cinnamon, balsam of Peru, and honey. It is widely used in the fragrance, food, and cosmetic industries due to its pleasant aroma and potential health benefits.

One important aspect to consider when working with any chemical compound is its flammability. In the case of cinnamic acid, it is essential to understand its flammability properties and safety precautions that should be taken. So, is cinnamic acid flammable?

Yes, cinnamic acid is flammable. It has a flash point of 134°C (273°F) and can ignite under specific conditions. The flash point is the lowest temperature at which a substance can vaporize to form an ignitable mixture with the air near its surface.

It is important to note that the flash point of a substance is just one factor to consider when determining its flammability. Other factors such as the concentration of the substance, presence of other flammable materials, and the presence of an ignition source also play a crucial role in determining whether a substance will ignite or not.

Handling and Storage of Cinnamic Acid

When working with cinnamic acid or any flammable substance, following proper handling and storage procedures is essential to ensure safety. Here are some guidelines to keep in mind:

  • Store cinnamic acid in a cool, dry, and well-ventilated area away from sources of ignition.
  • Avoid direct exposure to heat, sparks, or open flames.
  • Handle the substance with gloves, protective clothing, and safety goggles to prevent any contact with the skin, eyes, or inhalation.
  • Use non-sparking tools and equipment when working with cinnamic acid.
  • In case of a fire, use appropriate fire-fighting equipment and follow the recommended procedures.

Autoignition Temperature and Combustibility

In addition to the flash point, another important parameter to consider when assessing the flammability of a substance is the autoignition temperature. The autoignition temperature is the minimum temperature at which a substance can spontaneously ignite without an external ignition source.

In the case of cinnamic acid, its autoignition temperature is approximately 565°C (1049°F). This means that if the substance reaches or exceeds this temperature, it can ignite and sustain a fire even without the presence of an external ignition source.

Furthermore, cinnamic acid is combustible, which means that it can burn or support combustion. Combustible substances have the potential to release heat and flammable gases when ignited, leading to fire and potential hazards.

Environmental Impact

Aside from its flammability properties, it is also important to consider the environmental impact of cinnamic acid. This compound is biodegradable and poses low risks to the environment when handled and stored properly.

However, like any chemical substance, it is essential to follow appropriate protocols for disposal to prevent any negative impact on the environment. Always refer to local regulations and guidelines for the safe disposal of cinnamic acid and its related waste materials.

Frequently Asked Questions For Is Cinnamic Acid Flammable? Discover The Shocking Truth!

Is Cinnamic Acid Highly Flammable?

Cinnamic acid is not highly flammable, but it is combustible and may catch fire if exposed to extreme heat or open flames.

Can Cinnamic Acid Cause Fire?

While cinnamic acid itself is not flammable, it can ignite and cause fire if it comes into contact with an ignition source such as an open flame or a spark.

What Precautions Should Be Taken While Handling Cinnamic Acid?

When handling cinnamic acid, it is important to store it in a cool, well-ventilated area away from heat and ignition sources. Use appropriate personal protective equipment and follow good laboratory practices to minimize any potential risks.

What Fire Extinguisher Should Be Used For Cinnamic Acid Fires?

In case of a fire involving cinnamic acid, a dry chemical or carbon dioxide fire extinguisher should be used. Water can be ineffective and may spread the fire if the acid is in a liquid form.


In conclusion, cinnamic acid is a flammable compound with a flash point of 134°C (273°F). It is essential to handle and store it cautiously, following all safety guidelines, to prevent the risk of fire. Always use appropriate protective equipment when working with cinnamic acid to minimize exposure. Additionally, be mindful of its autoignition temperature of approximately 565°C (1049°F), as exceeding this threshold can result in spontaneous ignition. By taking the necessary precautions and following proper handling and storage procedures, the potential hazards associated with cinnamic acid can be minimized, ensuring both safety and environmental preservation.
