Science
Mechanism of Action
Its positive charge enables electrostatic binding to negatively charged keratin on skin and hair, forming a lightweight, uniform, and flexible film. This film acts as a conditioning barrier, reducing static and protecting the surface from moisture loss.
Research
Clinical Evidence
High confidence0.1%
Key findings
- 01 Clinical use in body washes and facial cleansers at 0.1-5% significantly reduces slippery after-feel during rinsing and modifies foam density, improving sensory profiles.
- 02 At 0.1%, it provides optimal post-wash skin softening in soaps and facial cleansers without leaving a greasy residue.
- 03 It also enhances wet/dry combability in hair care products.

The Formula
Formulation
Stability
Highly stable across a wide pH range (2.0-9.0), it can be used in cold processes and tolerates heat up to 80°C.
Conflicts
- Anionic surfactants (may form complexes, though often used in SLES systems at low concentrations)
- Strongly anionic thickeners (e.g., Carbomer) due to charge interaction causing precipitation or viscosity loss
Safety
Safety Profile
The CIR Expert Panel deemed it safe, provided residual acrylamide monomer is kept below 2 ppm or undetectable levels. Its large molecular weight (5,000-250,000 g/mol) prevents skin penetration.
