What is sodium metasilicate? Is it safe?

Na2SiO3

According to the Material Safety Data Sheet (MSDS), it is slightly corrosive and is an irritant. If exposed to skin, it may cause blistering. In a household cleaner, it is probably safe since it is probably diluted a lot. Just don't ingest it. It should corrode anything in a dilute state like a cleaner. According to this MSDS, its color is "Not Available."

I wish I had more information on this, sorry D:

Check the MSDS out for yourself. It's pretty straight-forward.

Color would be in physical properties which is section 9.

Ehh sorry the link doesn't work. go to Google and type in Na2SiO3 MSDS

It should be the first link available,

Good luck in your research!

Sodium Metasilicate

Sodium Metasilicate Na2O3Si

CAS # [6834-92-0]

Synonyms: Disodium Metasilicate, Disodium Monosilicate, Orthosil, Metso Beads, Drymet, Silicic acid (H2SiO3), disodium salt

Sodium Metasilicate is formed by the high temperature fusion of sodium carbonate and silicon dioxide. Sodium Metasilicate forms highly alkaline solutions when dissolved in water.

It is commonly used as a component of cleaners such as dishwasher detergent and laundry detergent.

In concentrated form, it is considered a hazardous substance:

2. SUMMARY

2.1 Main risks and target organs:

Sodium metasilicate is strongly irritating to the skin,

eyes and respiratory tract. Acute exposures involving the inhalation of dusts may result in irritation of the respiratory tract and corrosive damage may result from contact with mucous membranes. Prolonged exposures can lead to inflammatory changes and ulcerative problems in the mouth. Possible bronchial and astrointestinal problems can occur, depending upon concentration and duration of exposure.

However, in the concentrations typically employed in most detergent or cleaner formulations, sodium metasilicate does not pose much of a risk, but in general one should avoid inhaling or ingesting detergent or cleaner products. Use gloves when working with detergent solutions and household cleaners to avoid skin irritation. Make sure the area is well-ventilated and avoid breathing aerosol fumes. Never mix bleach with detergent or household cleaner products as a hazardous reaction will occur releasing dangerous fumes.
