POLYTETRAFLUOROETHYLENE ACETOXYPROPYL BETAINE.

Avoid CAS 123171-68-6 / HAIR CONDITIONING

Polytetrafluoroethylene Acetoxypropyl Betaine is a polymeric betaine derived from PTFE, primarily used to enhance the textural and sensory qualities of cosmetic products. It facilitates smoother product application and improves consistency, while its betaine component may offer supplementary skin conditioning benefits.

Science

Mechanism of Action

Operating as a polymeric betaine, this ingredient primarily functions to optimize the tactile experience of formulations by serving as a bulking agent, refining texture, and decreasing friction for effortless application. The integrated betaine fraction is recognized for its potential in skin protection, moisturization, and aiding in cellular water balance, which can also contribute to making cleansing formulations gentler.

Stability

The Polytetrafluoroethylene (PTFE) backbone of this ingredient demonstrates high chemical inertness and stability, showing resistance to water, strong acids, bases, and many organic solvents at moderate temperatures. While PTFE is inherently hydrophobic, this polymeric betaine is likely formulated to create stable aqueous dispersions, though specific stability data for the combined compound is not available.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk High

As a polymeric betaine, Polytetrafluoroethylene Acetoxypropyl Betaine is classified within the per- and polyfluoralkyl substances (PFAS) family. The Environmental Working Group (EWG) rates this ingredient as 'Unacceptable' due to substantial safety concerns, including potential for enhanced skin absorption, moderate endocrine disruption, high persistence, bioaccumulation, and moderate non-reproductive organ system toxicity. Furthermore, the PTFE component carries a risk of contamination from PFOA, a known substance linked to serious health issues such as cancer and reproductive toxicity. A comprehensive safety assessment by the Cosmetic Ingredient Review (CIR) Expert Panel specifically for this combined ingredient has not been conducted.
