TALLOWAMIDOPROPYL DIMETHYLAMINE.

Avoid CAS 68425-50-3 / ANTISTATIC, SURFACTANT - CLEANSING

Tallowamidopropyl Dimethylamine functions primarily as a surfactant and antistatic agent, capable of imparting a soft texture. However, its use in skincare is significantly restricted by a high potential for contact allergy, often linked to manufacturing impurities.

Summary

Antistatic agent Surfactant Hair conditioning agent Emulsifier

Science

Mechanism of Action

This ingredient operates as a cationic surfactant and antistatic agent, assisting in the neutralization of static charges. Structurally, it shares similarities with compounds like stearamidopropyl dimethylamine, which are recognized for their ability to condition surfaces, creating a smooth feel and mitigating negative charges. A related substance, Tallowamidopropyl Dimethylamine Oxide, further demonstrates its potential as an emollient, emulsifier, and foaming agent.

Stability

Formulations necessitate rigorous control over impurities such as dimethylaminopropylamine (DMAPA) and 'amidoamine', due to their documented sensitizing potential. Additionally, preventing the formation of nitrosamines is crucial for formulation stability and safety.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk High

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that fatty acid amidopropyl dimethylamines, including Tallowamidopropyl Dimethylamine, are safe for cosmetic use provided they are formulated to be non-sensitizing, likely based on a quantitative risk assessment. However, no specific maximum safe use concentration for Tallowamidopropyl Dimethylamine was reported, and it was listed as 'not in current use' in the Voluntary Cosmetic Registration Program (VCRP) in 2019. A primary safety concern is its significant potential for contact allergy, often attributable to manufacturing impurities like DMAPA and amidoamine. Formulations must actively avoid nitrosamine formation. No information regarding SCCS or FDA status for this specific ingredient has been identified.

Our Assessment

Verdict

Avoid

Considering the documented high potential for contact allergy, especially due to impurities, and its 'not in current use' status, Tallowamidopropyl Dimethylamine is not recommended for precision skincare formulations.
