Functions
Buffering
Chelating
Grabs onto metal ions in water that would destabilize the formula. Keeps your product from going bad or changing color.
Humectant
A moisture magnet. Pulls water from the air and deeper skin layers up to the surface to keep skin plump and hydrated.
Locks In Moisture
Traditional Use
A uronic acid found naturally in plant cell walls, isolated and studied in the 20th century. Its use in cosmetics is modern, developed for its potential moisturizing and skin-conditioning properties rather than traditional use.
