Hydroxybutanedioic acid

Apples are the richest source of malic acid. However, it is also found in other fruits and vegetables, like for example in quinces, gooseberries and grapes.

Everybody knows the old saying “An apple a day keeps the doctor away“ – and a large reason why this is true is because apples contain malic acid! This healthy, natural substance is often taken as a dietary supplement to increase the physical endurance of athletes.

The cosmetics industry uses a combination of dicarboxylic acids and hydroxycarboxylic acids. They offer intense hydration and a keratolytic effect and they promote the skin’s cell metabolism.
