Glass Chemical strengthening with potassium nitrate salt: consist on an Ion Exchange between sodium and potassium. Sodium comes from the glass and potassium from the Potassium Nitrate. When potassium replaces sodium, because the atom is bigger, it firstly causes glass expansion, but later on it causes a Surface compression that allows the glass to get stregther.

Surface compression test is performed by the Quality Control lab of glass manufacturers to evaluate the effectivity of the Ion Exchange and the quality of Potassium Nitrate.

There are 3 type of glass:

• Soda Lime Silicate glass (SLS)
• Sodium Alumino Silicate glass (SAS)
• Lithium Alumino Silicate glass (LAS)

SLS and SAS glass are processed by Potassium Nitrate. During Ion Exchange, sodium in the glass is replaced by the Potassium of the salts. LAS is normally processed by Ion Exchange in a Sodium Nitrate bath.

Quality Chemicals offers the following products suitable for glass chemical strengthening:

• Potassium nitrate, our code 145804, PS grade
• Potassium nitrate, our code 145827, PAI grade

PAI grade has a lower sodium content than PS:

• PS →  Max 0.1%
• PAI → Max.0.01%

Among other applications, the lead bioxide that offers Quality Chemicals is suitable for:

• Pyrotechnics
• Explosive pastes
• Detonators
• Digital dental impression devices
• PVC stabiliser

Fluoride in toothpaste is a mineral that was first added to toothpaste over a century ago. High fluoride content provides remineralizing action and protects enamel: the fluoride is absorbed into the enamel of the teeth, it makes teeth stronger and more resistant to decay caused by acid and bacteria. And although there are various types of fluoride used in oral care, sodium fluoride toothpaste is the most effective product.

Sodium fluoride also happens to be the most common form of fluoride in mouthwashes.

We offer sodium fluoride GMP (our code 3533) to guarantee a safer and more controlled quality of the toothpaste.

Sodium hydroxide is widely accepted for the following applications:

• Facility and equipment sanitization
• Chromatography column resins cleaning, sanitization and storage pH adjustment of process streams

The benefits of its use include efficacy, low cost, and ease of detection, removal, and disposal. Sodium hydroxide has been shown to be effective in removing proteins and nucleic acids as well as in inactivating most viruses, bacteria, yeasts, fungi, and endotoxins. It is common practice in industrial manufacturing to save time by adding a salt, such as sodium chloride, to the sodium hydroxide solution to combine cleaning with sanitization.

We offer sodium hydroxide solutions produced under cGMP. Below our current product range, however, we can manufacture any required concentration.

Many toothpaste manufacturers are adding potassium nitrate into their toothpastes to avoid the pain of sensitive teeth and gums, it helps alleviate the painful. It is the main ingredient in sensitivity toothpaste.

Tooth hypersensitivity happens when there is damage to enamel, irritating the nerves cells and making teeth vulnerable to hot, cold, acidic food and liquids. Within the nerve cells of the teeth, there is a higher amount of potassium ion concentration on the inside and sodium ions higher on the outside. When sensitivity and pain are experienced, potassium ions shift from the inside to the outside of the cell and vice versa.

Potassium nitrate is filtered into the surface of the enamel of the teeth, reaching the nerves inside and blocks the signals that the nerves in the teeth send to the brain.

Teeth can be sensitive for several reasons, mostly from enamel decay. Others have cracks in their teeth or cavities, and some have worn away their gums, exposing the delicate nerve endings to the food or beverages.

We offer potassium nitrate free-flowing ( our code 1062 ) with no need to add an anti-caking agent. The main advantage for the free-flowing version potassium nitrate is:

• The increase on productive manufacturing time
• Decrease the risk of operator injury

Selenium deficit is a reality in animals.

Plants (forage and grain crops) are the major dietary source of Se.

The Se content of plants is influenced by the concentration and availability of Se in the soil.

The cause of Se deficit in animals may be because of the low Se level in soil.

An important factor affecting Se content of forages is soil pH. In general, plants grown in acidic soil will absorb less Se than plants grown in alkaline soils.

In order to overcome the low dietary levels of Se for animals, it can be administrated through a mineral supplement. Se is usually added to the feed in inorganic forms as sodium selenite.

Quality Chemicals offers Sodium Selenite GMP as an API, our code 352514, to be added to a multivitamin supplement for cattle and poultry.
