Tetrasodium Etidronate

Tetrasodium Etidronate is a synthetically derived chemical widely used in cosmetics and personal care products. It functions primarily as a chelating agent, emulsion stabilizer, and viscosity regulator, effectively binding metal ions to prevent them from affecting the stability and quality of the products. Tetrasodium Etidronate also helps maintain the color and consistency of products and combats calcium ions in water, thus enhancing the effectiveness of surfactants. Although similar to EDTA and with lower biodegradability, it is considered safe under proper usage conditions.

Effect in Cosmetics

Tetrasodium Etidronate has various effects and applications, some of which are listed below:

Chelating Agent: Binds metal ions, improving the stability and quality of cosmetics.
Emulsion Stabilizer: Helps mix oil and water, increasing the stability of emulsified products.
Viscosity Regulator: Adjusts the viscosity of cosmetics, improving the feel of use.


Source: Entirely synthesized.
Extraction Process: Produced through a chemical synthesis process by reacting Etidronate with sodium to obtain its tetrasodium salt form.

Globally Harmonized System of Classification and Labelling of Chemicals 

According to the European Chemicals Agency (ECHA), Tetrasodium Etidronate may have the following hazards:

Harmful if swallowed - Acute toxicity
High concentrations may cause skin irritation
May cause eye irritation

Despite these potential hazards, Tetrasodium Etidronate is considered safe in cosmetics when used within the concentrations and conditions prescribed by EU and Taiwanese regulations.
