Trisodium nitrilotriacetate CAS Number: 5064-31-3

Description: Trisodium nitrilotriacetate, with the chemical formula C6H6NNa3O6, is an ingredient that has been used in cosmetics. It is also known by its INCI name, Trisodium NTA. This compound has historically been employed for its chelating properties in cosmetic formulations.

Synonyms and Other Names:
  • Trisodium NTA
  • Nitrilotriacetate Sodium
  • Sodium Nitrilotriacetate
Uses in Cosmetics: Trisodium nitrilotriacetate has been used in cosmetics primarily for its chelating abilities. Chelating agents are substances that bind to metal ions, helping to improve the stability and effectiveness of cosmetic products. In cosmetics, they are often used to maintain the product's quality and appearance by preventing the degradation of ingredients due to the presence of metal ions.

Skin Sensitivities and Allergies: There have been concerns about the potential for certain chelating agents, including Trisodium nitrilotriacetate, to cause skin sensitivities and allergies. Chelating agents can be irritating to the skin, particularly in individuals with sensitive skin. They may lead to skin reactions such as redness, itching, or discomfort. It is advisable for individuals with sensitive skin to be cautious when using products containing chelating agents.

Other Risks Associated with Use: While Trisodium nitrilotriacetate itself may not be considered highly hazardous, its use in cosmetics has been scrutinized due to potential concerns about skin sensitivities and environmental impact. Chelating agents like Trisodium nitrilotriacetate can persist in the environment and may contribute to water pollution if not properly managed.
California Ban (Assembly Bill No. 496): Starting from January 1, 2027, California has implemented a ban on the use of Trisodium nitrilotriacetate in cosmetics. 
This legislative action is part of Assembly Bill No. 496, which seeks to regulate and prohibit the use of certain ingredients in cosmetic products due to concerns about their safety and environmental impact. As such, cosmetic brands are required to remove products containing Trisodium nitrilotriacetate from the market to comply with California's regulations.

This ban aligns with the state's commitment to consumer safety and environmental protection. It underscores the importance of careful ingredient selection in cosmetics, especially for individuals with sensitive skin who may be more susceptible to adverse reactions.
