Is Ajax Flammable? (A Comprehensive Overview)

Is Ajax Flammable?

Ajax cleaning products are not flammable. But they can act as combustible materials.

Ajax powder cleanser with bleach, Ajax Dish Soap and Ajax Spray & Wipe have a fire hazard degree of 1 according to the safety data sheet provided by the company website.

A fire hazard degree of 1 refers to materials that require considerable preheating before ignition can occur, according to the information found on the National Fire Protection Association (NFPA) of the United States of America website. 

The same degree of fire hazard (1) is attributed to Ajax dish soaps and Ajax Spray & Wipe.

In other words, the above mentioned ajax cleaning products pose a significantly low risk of catching on fire under normal conditions. For them to possibly be ignited and sustain a fire, intense preheating would be necessary.

What are Ajax Fire Hazards?

The fire hazards associated with the forego ajax cleaning products are low.

Increase in Electrical Conductivity of Water

When mixed with water, some cleaning products can increase electrical conductivity, given the increase in electrolytes in the solution in comparison with pure water.

A furniture or floor that was recently cleaned can momentarily turn more electrically conductible.  Posing a small risk for sparks to occur.

Cleaning Products Contain Substances that can Produce Hazardous Gases if in Contact with other Chemicals

Mixing the cleaning products with reactive substances such as ammonia or strong oxidizers. Besides producing toxic vapors, mixing cleaning products with ammonia can produce flammable or explosive gases.

Some hygiene products or other cleaning products may contain trace amounts of ammonia. Therefore, mixing different products may pose some danger.

Under What Circumstances Can Ajax Cleaning Products Burn?

In situations of extremely high temperatures, above 800 ºC, some cleaning products can become able to catch on fire if in contact with a naked flame or sparks.

Further Insights on Selected Ajax Cleaning Products

Following three ajax cleaning products will have their ingredients listed along with individual properties of each ingredient (that is the pure substances).

  • Ajax Dish Soap
  • Ajax Powder Cleanser
  • Ajax Spray & Wipe

Some Information on Ajax Dish Soap (Without Bleach)

This cleaning product has a variety of formulations, none of them is considered flammable. The specific information in regards with its ingredients and safety precautions are in the products label.

Ajax Dish Soap Ingredients

Listed below are the ingredients of one specific dish soap (adapted from the company website). The main difference in the formulations of dish soaps is in regards to the colorants and with the fragrances.

As with most cleaning products, these dish soaps do contain substances which are flammable in pure form such as acetic acid. However, in mixtures containing mostly water and other non flammable substances, limone does not pose a significant fire hazard.

Sodium chlorideNaClNoNo

Ajax Powder Cleanser

This ajax product may catch on fire only in severe conditions. It is estimated that it would need to be heated to above 800 ºC based on its fire hazard degree.

If isolated from the whole formula, limonene and turpentine are themselves flammable substances. But for these substances to be isolated from the powder cleanser a very laborious (if not unfeasible) procedure would need to be performed.

Ajax Powder Cleanser Ingredients

Below the ingredients of this cleaning product are represented along with some fire related characteristics.

It is important to note that mixtures and pure substances have different behaviors. The information provided in this table is for the substance in its pure form at normal conditions. The cleaning product formula itself cannot be inferred from only these properties.

Ingredient nameChemical formulaIs it flammable?Is it combustible?
Calcium carbonateCaCO3NoNo
Sodium carbonateNaCO3NoNo
Trichloroisocyanuric acidC3Cl3N3O3No*Yes
Sodium chlorideNaClNoNo

(*)Trichloroisocyanuric acid is a strong oxidizing agent with possible chemical hazards.

Ajax Spray & Wipe

This cleaning product does contain some flammable substances in its formulation, such as ethanol, dipropylene glycol butyl ether and ethoxylated alcohols. Nonetheless the product itself is not flammable because the flammable substances are diluted in water.

This product can act as a combustible if exposed to continuous high temperatures.

Ajax Spray & Wipe Ingredients

Below the main ingredients for the formulation of Ajax Spray & Wipe adapted from the company website. The ingredients may be different in some cases, therefore the specific composition and safety recommendations to follow are provided in the product label.

Mixing Different Cleaning Products is Dangerous

Mixing different cleaning products or even cleaning products with cosmetics can be quite dangerous.

Cleaning often contains strong oxidizing substances in their formulations, bleach (sodium hypochlorite) and trichloroisocyanuric acid are common examples. They can react violently with substances from different products, in rare cases flammable gases can be produced.

If bleach (or a bleach containing product) is in contact with ammonia (or an ammonia containing product), monochloramine (ClNH2) is produced. Monochloramine, also called just chloramine, is extremely dangerous to human and animal health.

Besides its high toxicity, chloramine is also capable of catching on fire under high temperatures.

Although bleach can be present in high amounts in cleaning products, ammonia is less likely to be present in significant amounts in most common products.

Symptoms of Chloramine Exposure

The severity of symptoms of chloramine exposure depend directly on the amount of chloramine gas that was inhaled and on the conditions of the individual.

Symptoms include:

  • Irritation to the eyes causing tearing to the eyes.
  • Irritation to the nose.
  • Irritation to the throat and airway.
  • Irritation to the lungs, causing coughing and short breath. Higher exposure can lead to pulmonary edema.
  • High exposure can lead to coma or death.

Bleach and Ammonia Chemical Reaction

Below the chemical reaction equation of bleach (NaClO) and ammonia (NH3) is represented.

Chloramine is a volatile liquid at regular temperature and pressure.

The chemical reaction between bleach and ammonia also forms sodium hydroxide. Sodium hydroxide can promote the reaction to further produce hydrazine (N2H4) and water, hydrazine is also highly toxic to humans.

Brief Introduction On the Flammable and Combustible Terms

What does Flammable Mean?

A substance or mixture of substances are considered flammable if they can catch on fire when all the following conditions are true:

It is in contact with air.

A naked flame, spark or other ignition source is subjected to the given material.

The temperature is not above a specific value, usually 93 ºC.

The flammability of a given material is more accurately determined by classifications. Two different materials can both be flammable, while one of them produces a mild fire and the other burns violently and can even cause an explosion.

The competent authorities and associations provide more specific classifications which are based on tests, base knowledge and research.

What does Combustible Mean?

A combustible material is one that can catch on fire and sustain this fire in the presence of air.

A combustible material is not necessarily flammable.
