FAQ

What is Silicic acid, calcium salt (CAS: 1344-95-2)?

Silicic acid, calcium salt, also known as calcium orthosilicate, is an inorganic compound with the chemical formula Ca[(SiO3)2]. It is a white crystalline powder with a molecular weight of approximately 222.08. This compound is highly insoluble in water and is widely used in various industrial and pharmaceutical applications due to its pH-buffering and anti-adhesive properties.

What are the main uses of Silicic acid, calcium salt (CAS: 1344-95-2)?

Silicic acid, calcium salt is primarily used in the production of toothpaste and other oral care products for its anti-adhesion properties. It is also used in the paper industry as a waterproofing agent and in the pharmaceutical industry for its buffering capacity. Additionally, it serves as a food additive and is used in research for its chemical and thermal stability.

Is Silicic acid, calcium salt (CAS: 1344-95-2) safe?

Silicic acid, calcium salt is considered safe for its intended uses. It is not classified as toxic and has a low oral and dermal toxicity. However, it can cause irritation to the eyes and skin, and inhalation should be avoided. Proper handling and use of personal protective equipment (PPE) such as gloves and goggles are recommended. It should be stored in a cool, dry place away from direct sunlight and heat sources.

How should Silicic acid, calcium salt (CAS: 1344-95-2) be stored?

Silicic acid, calcium salt should be stored in a cool, dry place to prevent moisture absorption, which can affect its stability. It should be kept in a tightly sealed container to protect it from humidity and light. Avoid storing it near heat sources as it is sensitive to high temperatures. Ideal storage conditions include a room temperature of 15-25°C and a relative humidity below 60%.
