Description
A broad class of non-mineral acids that include formic, acetic, lactic, oxalic, citric, stearic, and tannic acids. Organic acids occur naturally in plants, fruits, animals, and microorganisms. They are much weaker proton donors than mineral acids, but can still have detrimental effects on materials, such as paper, leather, metals, and photographs. Of concern in a museum environment is the volatility of many of organic acids and their ubiquitous presence in many materials.
