1. What is Sodium metasilicate?
Sodium metasilicate, with the chemical formula Na2SiO3, is an inorganic compound belonging to the silicate group. This is a form of silicic acid, in which two sodium (Na) atoms are bonded to one silicon (Si) molecule and three oxygen (O) molecules. Sodium metasilicate typically appears as white crystals or powder, soluble in water, forming an alkaline solution.
This compound is widely used in industry as a detergent, rust inhibitor, and stabilizer in construction products. Sodium metasilicate has the ability to effectively clean and remove stains thanks to its strong alkalinity. At the same time, it also plays an important role in adjusting the pH of solutions during the production process.
However, although sodium metasilicate has many useful industrial applications, it also poses risks to human health. Long-term or improper exposure to this chemical can cause health problems such as skin irritation, inflammation, and respiratory damage. Therefore, a clear understanding of the properties and impacts of sodium metasilicate is very important to ensure safety for workers in manufacturing plants.

2. Where does Sodium metasilicate originate from in the production process?
This inorganic compound’s origin is mainly from production processes in the chemical and processing industries. During production, sodium metasilicate is typically created by combining silicon dioxide (SiO2) with sodium hydroxide (NaOH) or sodium carbonate (Na2CO3) under high-temperature conditions.
Specifically, in manufacturing plants, silica (silicon dioxide) is the main raw material melted with sodium hydroxide to create sodium metasilicate. This process takes place in specialized reactors, where the components are mixed thoroughly and heated for the chemical reaction to occur. After the reaction is complete, the sodium metasilicate product will be cooled and processed to achieve crystalline or powder form depending on the usage requirements.
In addition, sodium metasilicate can also appear during the production of other products such as industrial detergents, rust inhibitors, and construction products, when it is used as an additive to improve the product’s features. In these cases, sodium metasilicate can be generated during processing or raw material mixing steps.
Clearly understanding the origin of sodium metasilicate in the production process not only helps identify high-risk points in the work environment but also helps establish effective preventive and health protection measures for workers.
3. Industries that use Sodium metasilicate in production
Sodium metasilicate is a chemical compound with many applications in various industries thanks to its effective cleaning and pH-adjusting properties. Industries that use sodium metasilicate in production include:
The detergent industry is one of the most common fields using sodium metasilicate. In industrial cleaning products, sodium metasilicate acts as a cleaning agent and water softener, helping to remove stubborn stains and increase the effectiveness of other detergents. It is often used in detergents for machinery, equipment, and industrial surfaces.
The construction industry also utilizes sodium metasilicate in the production of building products. Sodium metasilicate is used as an additive in mortars and concretes to improve their properties, such as waterproofing and enhancing adhesion. This compound helps protect building structures from damage caused by environmental factors.
In addition, sodium metasilicate is also used in the water treatment industry. In water treatment plants, sodium metasilicate is used to adjust pH and increase the efficiency of the purification process. It helps remove sediment and impurities, ensuring water quality meets safety standards.
In the pulp and paper industry, sodium metasilicate also plays an important role. This compound is used in the processing and bleaching of paper, helping to improve the brightness and quality of the final product. Sodium metasilicate also contributes to reducing the amount of toxic chemicals needed in the paper production process.
4. How does Sodium metasilicate affect workers
Sodium metasilicate, despite its many useful industrial applications, can also cause serious health effects for workers if not used and managed properly. Direct contact with sodium metasilicate can lead to several serious health problems.
When inhaling sodium metasilicate dust or vapors from solutions containing this compound, workers may experience respiratory irritation symptoms. This includes coughing, difficulty breathing, and sore throat. In severe cases, it can cause chronic respiratory problems or worsen asthma conditions.
Skin contact with sodium metasilicate can lead to skin irritation, including redness, itching, and rashes. This chemical has strong alkalinity, which can damage the skin’s natural protective layer, leading to dryness and dermatitis. In cases of long-term contact, the skin can become chapped and at risk of infection.
In addition, sodium metasilicate can also cause eye problems if it comes into direct contact as a solution or dust. This can lead to eye irritation, redness, and a burning or painful sensation. In severe cases, it can cause serious damage to the cornea and affect vision.
To protect workers’ health, implementing safety measures is very important. This includes using personal protective equipment such as gloves, safety goggles, and dust masks when working with sodium metasilicate. At the same time, maintaining good ventilation in the work area and adhering to occupational safety regulations also helps minimize exposure risk and protect workers’ health.
5. Permissible safe concentration of Sodium metasilicate for human exposure
The permissible safe concentration of sodium metasilicate for human exposure depends on the regulations and guidelines of health and occupational safety agencies. To ensure worker health, these agencies often issue specific concentration limits that workers can be exposed to without facing significant health risks.
According to international standards and regulations in many countries, the concentration of sodium metasilicate in the air must be strictly controlled to limit the risk of inhaling dust or vapors from this compound. For example, the US Occupational Safety and Health Administration (OSHA) stipulates that the maximum permissible concentration of sodium metasilicate in the air is 2 mg/m³ for one work hour. However, these standards may vary by country and occupational safety management organization.
For skin contact, no specific concentration level is defined, but long-term contact with sodium metasilicate can cause irritation and skin damage. Therefore, the use of personal protective equipment such as gloves and protective clothing is very important to minimize direct contact with this chemical.
In addition, in work areas where sodium metasilicate is used, maintaining good ventilation and implementing preventive measures such as proper cleaning and disinfection also helps control the concentration levels of the chemical in the air and on surfaces, thereby protecting workers’ health.
At a basic level, if working in an industrial environment, adhering to safety standards and limiting exposure to Sodium silicate is important. Organizations like the Occupational Safety and Health Administration (OSHA) in the United States provide guidelines and safety principles to protect workers from the negative impacts of chemical substances.
