What the % on the label really means
You will almost never see a percentage claimed for allantoin, and you do not need one — it works at the low levels everyone uses.
⚠️ Ceiling: It dissolves in water only to about 0.5% at room temperature, so most formulas sit at or below that. Higher levels have to be dispersed rather than dissolved, and will crystallise back out if they are not.
