Inspired by a toothache

Up to 90% of adults in the UK have some form of gum disease.

This can range from mild inflammation to advanced periodontal disease.

Left undressed, it can affect your entire body. Gum disease is linked to Alzheimer's disease, cardiovascular diseases, diabetes complications and premature labour. 

Care for your whole mouth, not just your teeth with our organic botanical oral care.

No artificial additives. No plastics. No palm.

Should you avoid using metal with bentonite clay? - truthpaste

Should you avoid using metal with bentonite clay?

At Truthpaste, we prioritise both the effectiveness and safety of our products. One common concern we encounter is whether metal utensils can interfere with the properties of bentonite clay in our toothpaste. Let's dive into the science and clear up any misconceptions.

 

What is bentonite?

Bentonite clay, a key ingredient in our toothpaste, is renowned for its high adsorption capacity. This unique property stems from its layered structure and net negative charge, which allows it to attract and bind positively charged ions and impurities.

It is used in cosmetics or therapeuticals to help absorb toxins, heavy metals and other impurities.

 

Is bentonite abrasive in toothpaste?

Used in oral care, it can help clean and polish teeth. Due to its unique properties, it has a lower abrasivity score but higher cleaning efficiency. It scores 1.5-2.0 on the Mohs Hardness Scale.  

 

 

Does using metal de-activate bentonite clay?

First, what does ‘activated’ mean?

In the context of charcoal or bentonite, the term ‘activated’ refers to a process that enhances the material’s ability to absorb substances by increasing its surface area. 

 

 

What does ‘deactivating’ mean in terms of bentonite?

If activating bentonite refers to increasing its ability to absorb substances, then ‘deactivating’ bentonite would mean losing its ability to absorb substances.

 

How does bentonite clay become ‘deactivated’?

Bentonite's adsorption properties depend primarily on its physical structure and chemical composition. If bentonite was to come into contact with certain contaminants, its absorption efficiency could be affected.

 

Can you use stainless steel with bentonite?

Stainless steel does not chemically interact with bentonite in a way that would deactivate it. Stainless steel is a common material used in various industrial applications due to its resistance to corrosion and contamination.

Stainless steel is generally resistant to corrosion and does not easily leach substances that would contaminate bentonite. However, if the stainless steel surface is contaminated with oils, greases, or other substances, these contaminants could transfer to the bentonite and potentially affect its performance.

 

Does Using Metal ‘Deactivate’ Bentonite?

If the metal utensil or container is corroded or contains reactive metals, there might be a risk of introducing metal ions into the clay. However, stainless steel and most common metals used in kitchen utensils are non-reactive and unlikely to leach significant amounts of ions that could affect the clay’s properties.

 

What metals should you avoid with bentonite?

Specific metals that should be avoided with bentonite include iron, copper, and aluminum, as they are reactive and can potentially affect the clay's properties.

The aluminium used our packaging is coated with a food safe resin to prevent contamination.

 

Can metal interfere with bentonite clays negative charge?

Bentonite clay is primarily composed of montmorillonite, which has a layered structure with a net negative charge. This negative charge allows bentonite to attract and bind positively charged ions (cations) and molecules.

The effectiveness of bentonite clay in adsorbing toxins, heavy metals, and other impurities is due to its high surface area and negative charge. The negative charge is a result of isomorphous substitution within the clay structure, which is a stable property not easily altered by brief contact with metals.

Short-term contact with metal utensils (like stirring with a metal spoon or storing in a metal container) is unlikely to alter the fundamental charge properties of bentonite clay.

The negative charge on bentonite is due to its crystalline structure and is stable under normal conditions (ie without being subjected to intense heat or pressure).

 

In summary, the negative charge of bentonite clay, which underpins its adsorptive properties, is derived from its stable crystalline structure and is not easily altered by brief contact with metal utensils.

Therefore, using stainless steel or other common kitchen metals with bentonite clay is unlikely to deactivate or significantly affect its effectiveness.

However, it is important to avoid contamination through reactive metals, corroded metals, or utensils or storage containers (metal or non-metal) that are contaminated with oils, grease, or other contaminants.

Embracing Sustainability: Why We Choose to Avoid Plastic Refill Pouches for Our Toothpaste

In today's world, environmental concerns have pushed industries to reevaluate their practices and adopt more sustainable approaches. The personal care sector, including oral hygiene products, has come under scrutiny for its environmental impact. While many companies are striving to address this issue, the use of plastic refill pouches for toothpaste raises significant concerns that warrant closer examination.
