Our take
Is Isodecyl Salicylate a Good Ingredient?
Rated Good because it's a light ester emollient that improves glide and comfort, with a solid track record in formulations. It's generally gentle, but those with salicylate sensitivities should exercise caution, which is enough to keep it out of the top tier.
