Humectant
Also known as: moisture retention agent, water retention agent, wetting agent, moisture retention
Humectant is an umbrella functional category rather than a single ingredient; safety depends entirely on which specific humectant is used. Without disclosure, consumers cannot evaluate the actual additive (e.g., glycerin is GRAS, while propylene glycol has intake limits).
