FAQ

Q.Does tetrasodium edta cause cancer?

A.No, Tetrasodium EDTA does not cause cancer.

Q.Is tetrasodium edta safe?

A.Yes,Tetrasodium EDTA is safe. It does not release or break down into formaldehyde.

Q.What is difference between disodium EDTA and tetrasodium EDTA?

A.Tetrasodium EDTA 4Na-EDTA is used more in industry as it has higher alkaline with Ph value 10.50-11.50. Disodium EDTA is more used for personal care as its ph value 4.00-5.00 is mild.

Q.Is tetrasodium edta good for hair or skin?

A.Yes. Tetrasodium EDTA is mainly a chelating agent to aid in preservation with controlled percentages. Normally it’s fine to sequester undesirable metal ions in various purposes including skin care and hair care.

Q.What does tetrasodium edta do?

A.Tetrasodium EDTA binds metal ions (chelating agent) which makes it use for water treatment, industrial cleaning and personal care products.

Q.what is tetrasodium edta made from?

A.Tetrasodium EDTA is produced by neutralizing EDTA with sodium hydroxide (NaOH). The reaction equation is as follows.

EDTA + 4NaOH → EDTA-4Na + 4H₂O

Q.Where to buy Tetrasodium EDTA?

A. The top factories for Tetrasodium EDTA are BASF, Dow Chemical Company, and AkzoNobel N.V.. Many customers consider purchasing from China due to its cost-effectiveness and stable supply. In addition, Huashihang Chemical (HSH Chemical) is a professional supplier providing Tetrasodium EDTA with competitive pricing and EDTA series products capacity is up to 300,000 metric tons.
