Stability and Storage: D-Panthenol is stable to air and light but unstable to heat. Stored at below 25 ºC in tightly sealed, original containers, it has a shelf life of 24 months. In weakly acidic, aqueous solutions, D-Panthenol is considerably more stable than the salts of pantothenic acid. It is unstable in strong acids and bases.
