Silica sol is mainly composed of silica particles, water and trace stabilizers (such as Na+, K+, NH4+), so it is listed as one of the most environmentally friendly industrial chemicals. Silica is the main component of sand, quartz, and crystal. It is a non-toxic and tasteless mineral, so silica sol is not listed as a hazardous chemical. Silica is widely used in the food industry, such as food-grade silica powder used as food dispersant, anti-caking agent, etc.; silica sol is often used as a flocculant in food processing industries such as fruit wine and beverages to improve the clarity of the product. Therefore, silica sol is a chemical that is harmless to the environment.
Silica sol is not listed as a harmful chemical and is not a dangerous chemical, but it is mildly irritating (alkaline like soapy water, acidic like vinegar). When using silica sol, it is best to wear protective gloves and goggles. When it comes into contact with the skin, wash the contact area with plenty of water; when it comes into contact with the eyes, rinse with plenty of water. If the symptoms do not ease, please seek professional medical treatment.
