PHOSPHONOBUTANETRICARBOXYLIC ACID.

Insufficient Data CAS 37971-36-1 / ANTICORROSIVE, BUFFERING, CHELATING

PHOSPHONOBUTANETRICARBOXYLIC ACID (PBTC) is a highly effective chelating agent used to enhance product stability. It neutralizes detrimental metal ions in formulations, preserving ingredient efficacy and extending shelf life. Furthermore, it contributes as a buffering and anticorrosive agent.

Science

Mechanism of Action

In skincare formulations, PHOSPHONOBUTANETRICARBOXYLIC ACID primarily acts as a robust chelating agent. It forms stable complexes with multivalent metal ions, including calcium, magnesium, zinc, and copper, preventing them from interacting with other ingredients. This action significantly improves the overall stability and performance of the product, mitigating issues such as discoloration or degradation. PBTC also offers secondary benefits by contributing to pH stabilization and providing anticorrosive properties within the formulation matrix.

Dusting Analysis

Not commonly dusted

PHOSPHONOBUTANETRICARBOXYLIC ACID functions primarily as a formulation stabilizer and chelating agent, rather than an active ingredient providing direct skin benefits. Therefore, the concept of 'dusting' is not applicable to its typical use in skincare.

Not reviewed
Sensitization risk Unknown

While PHOSPHONOBUTANETRICARBOXYLIC ACID possesses an FDA UNII number (306P37319L), this merely indicates registration and not a specific safety assessment or approval for cosmetic use. There is currently no dedicated safety assessment from the Cosmetic Ingredient Review (CIR) or the Scientific Committee on Consumer Safety (SCCS) for its application in cosmetic products. Industrial safety data indicates that in concentrated forms, it is listed as an irritant to skin and eyes, necessitating careful handling.

Our Assessment

Verdict

Insufficient Data

While PHOSPHONOBUTANETRICARBOXYLIC ACID is a highly effective chelating agent for formulation stability, the absence of comprehensive safety and efficacy data specifically for cosmetic applications results in an 'insufficient-data' verdict.
