About
A synthetic polymer used to improve texture, film formation, adhesion, or wear rather than act as a classic active.
This is a large synthetic polymer used mostly for texture, slip, film formation, adhesion, or conditioning rather than deep biological activity. Intact polymers generally have low skin penetration, so the main safety question is usually residual monomers, solvents, or catalyst impurities left from manufacturing.
Function
Skin benefits
- Supports the skin barrier or reduces moisture loss
Known concerns
- Residual crosslinker-related impurities are the main concern.
