OATAMIDOPROPYL DIMETHYLAMINE.

Optional / ANTISTATIC, HAIR CONDITIONING, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

OATAMIDOPROPYL DIMETHYLAMINE is a versatile conditioning agent and surfactant, recognized for its ability to reduce static electricity and enhance the sensory feel of formulations. It functions as an emollient and softener, contributing to skin and hair suppleness.

Summary

Antistatic Hair Conditioning Surfactant (Emulsifying) Surfactant (Cleansing) Emollient Softener Foaming agent

Science

Mechanism of Action

As an amidopropyl dimethylamine, this ingredient primarily functions by interacting with negatively charged surfaces, such as hair cuticles, to smooth them, reduce static, and improve manageability. In skincare, its emollient properties allow it to soften and smooth the skin's surface, while its surfactant capabilities facilitate the creation of stable oil-in-water dispersions and aid in cleansing.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that OATAMIDOPROPYL DIMETHYLAMINE is safe as a cosmetic ingredient when formulated to be non-sensitizing, potentially through a Quantitative Risk Assessment (QRA). A key concern noted by the panel is the sensitizing potential of impurities, particularly 3,3-dimethylaminopropylamine (DMAPA). While no specific maximum use concentrations were reported for OATAMIDOPROPYL DIMETHYLAMINE, related ingredients like stearamidopropyl dimethylamine have reported maximums from 0.01% to 5% in non-coloring hair conditioners, and cocamidopropyl dimethylamine from 0.003% to 6.5% in skin cleansing products.
