Thickener
In plain language
A large, fluffy synthetic polymer used to create crystal-clear gels and stabilize emulsions by thickening the water phase.
Requires a neutralizer (like sodium hydroxide) to swell and thicken, leaving a very light, non-tacky feel.
Can 'pill' or ball up on the skin if too much is used or if layered incorrectly with other products.
