Is Vinegar flammable? (A comprehensive overview)

This blog post will answer the question, “Is Vinegar flammable?” and cover topics like the discovery of vinegar, its flammability, uses and hazards.

Is Vinegar Flammable?

The simple straightforward answer to this question is; “No, vinegar is not a flammable substance”. In fact, vinegar is made up of about 5-20 percent of acetic acid and the rest of it is made up of water alone. Since the percentage of acetic acid is quite low, it is difficult for vinegar to catch fire. Hence vinegar is not flammable.  

Contradictingly, the acetic acid present in vinegar is flammable. The only reason why vinegar cannot catch fire is because the acetic acid level is very low and it is completely diluted. If the acetic acid level is increased in vinegar, then the answer to the above question will be “yes”.

Discovery of Vinegar

The Babylonians were the first people to discover vinegar. The discovery of vinegar dates as early as approximately 3000 BC. Just like wine, vinegar was also made from fermenting fruits like grapes, apples, figs, etc. In those days, people used vinegar for medicinal purposes and also for cooking purposes which is still common even today. 

The Egyptians, Chinese and the Taiwanese people used vinegar in the olden days. Initially, vinegar making was a household art. Later it became a profession and the Europeans were the first to make vinegar professionally.

Vinegar and its flammability

We know that vinegar is not a flammable substance. Most part of the vinegar comprises of water and the percentage of acetic acid in vinegar is less than 20 percent. Although the percentage of acetic acid in vinegar may vary from one brand to another, the concentration of acetic acid will always be below 20 percent. This is the reason why vinegar is not flammable.

Uses of Vinegar

Vinegar is sometimes known as a magic ingredient because it has so many uses. Vinegar is quite versatile in nature. The use of vinegar ranges from cleaning, cooking to even medicinal purposes. One of the main reasons why vinegar is used in so many areas is because it is very cheap and it is available very easily. 

Some of the uses of vinegar are:

  • Vinegar for cooking purposes
  • Vinegar as a cleaning agent
  • Vinegar for medicinal purposes

Vinegar for cooking purposes

Vinegar itself is made by the fermentation of foods and it is used very commonly in the kitchen for cooking purposes. It is used for cooking a variety of cuisines as it has the capability to enhance the flavour of the dish. It is added to milk during the process of making cottage cheese. Since it is fermented, it is also used for making pickles and salad dressings. 

Sometimes, mocktail and cocktail drinks have some amount of vinegar in them to give it a better taste. Consumption of distilled vinegar is known to cause weight loss. This is why many people drink vinegar combined with hot water regularly for fat loss. Some studies show that vinegar is also used as a food additive in certain cases.

Vinegar as a cleaning agent

Vinegar is very commonly used for cleaning purposes. This is because the acetic acid present in it is capable of breaking down the oil and dirt and thereby aiding the cleaning process. Due to its acidic nature, it is very effective in cleaning surfaces that have harsh stains on them. Vinegar diluted with water is used to clean ceramics and mirrors by spraying it on the surface and then rubbing it with newspaper or a soft cloth. 

Vinegar is an excellent and cheap alternative to metal polishers. It can polish metallic surfaces with less time and effort. Only a very small amount of vinegar is needed for polishing. Also, it is surprising that vinegar can even be used for clogged drains as it breaks down the unnecessary materials responsible for clogging.

Vinegar for medicinal purposes

Vinegar has been used for medicinal purposes for over 2000 years. Vinegar is known to kill bacteria, yeast, fungus and other microorganisms. Hence it helps in treating infections and diseases caused by these microorganisms. Vinegar is used for cleaning wounds and thereby killing the germs which might worsen the wound.

It is also used to provide relief against irritation or rashes caused by stings. Ear infections and warts can also be treated with vinegar. Another important purpose of vinegar is that it controls blood sugar levels, cholesterol and improves the heart rate when consumed. Some studies show that vinegar is also used as a herbicide and to treat infected plants.

Hazards of Vinegar

Even though vinegar is not a flammable substance, it can be harmful as it is known to cause serious hazards to the skin, eyes, etc. 

Proper care must be taken while handling vinegar, especially while storing it as it may expand within the bottle and this may lead to an increase in pressure which may explode. Although this condition is rare, it is always better to be cautious. In such cases, the bottle must be opened slowly and carefully. It is advised to strain the vinegar before use as there might be some container debris present in it. Also, the containers must be washed and dried thoroughly if they have to be used again.

Some of the ways in which vinegar can be harmful are as follows:

  • Skin Hazard
  • Eye Hazard 
  • Inhalation hazard
  • Ingestion hazard 

Skin hazard 

Situations when the skin comes in contact with vinegar might be seen commonly in the kitchen. Kinds of vinegar that are made up of above 10 percent acetic acid cause such skin hazards. Contact with such kind of vinegar may result in slight burns and injuries. At times, milder vinegar concentrations can cause skin injuries like dermatitis in some people.

In such cases, the affected area must be thoroughly washed with clean water. If the problem still persists then he or she must be taken to a dermatologist immediately.

Eye hazard

Vinegar may come in contact with the eyes during cooking. Since the eye is a very sensitive area even milder concentrations of vinegar can cause problems like irritation. Sometimes, a higher concentration of vinegar is known to cause severe injuries such as permanent cornea loss in the eye and even cause blindness. Such kinds of vinegar can also cause issues like conjunctivitis.

In such cases, the eyes must be thoroughly washed with clean water. If the problem still persists then he or she must be taken to an ophthalmologist immediately.

Inhalation hazard

Inhalation of vinegar is known to cause irritation in the respiratory system of humans. Continuous inhalation of vapours of vinegar can cause serious problems to the respiratory system and thereby leading to damage of the entire system. The human respiratory system can withstand a maximum limit of 10 ppm of vinegar vapour inhalation. For a smaller duration of exposure of about 15 minutes, the limit is 15 ppm. 

In case of difficulty in breathing the person must immediately be given artificial respiration. Alternatively, the person must be immediately taken to the hospital.

Ingestion hazard

We know that vinegar is commonly used in cooking and can be consumed on a daily basis. But, higher concentrations of vinegar can pose serious hazards. Consumption of such vinegar is known to cause irritation, burns and even severe pain at times in the mouth, oesophagus, intestines and in the stomach. 

In such situations, water must be consumed immediately in order to dilute the vinegar and to avoid burns. Alternatively, the person must be immediately taken to the hospital if the situation worsens. It is always advisable to consume vinegar with the minimum concentration of acetic acid ( below 20%).

Frequently Asked Questions (FAQs): Is Vinegar flammable?

What is vinegar made of?

Vinegar is made up of acetic acid. It comprises 5 to 20% acetic acid and the remaining of it is made of water. 

Is acetic acid flammable? 

Yes, acetic acid is highly flammable. Hence it must be handled very carefully.

Can vinegar be consumed?

Yes, vinegar can be consumed. In fact, vinegar is used very commonly for cooking purposes. It enhances the flavour of the dishes and it is also used to make drinks like cocktails, etc.

Is distilled vinegar flammable?

No, distilled vinegar is not flammable. It also contains the same amount of acetic acid (5-20%) and hence it cannot burn easily.

What happens if vinegar is heated?

Vinegar should never be heated directly. Since it contains acetic acid which is highly flammable, heating vinegar can cause damage to the container, especially if it is metal. It can lead to corrosive damage to the metal when the vinegar crosses its boiling point.

What is the flash point of vinegar?

The flash point of vinegar is 40 °C. The flash point determines the point (temperature) when the substance will produce enough vapour and burn in the presence of air.
