Products Description
Malic acid can be made in two main ways: natural extraction and chemical synthesis. Natural extraction is mainly purified from apples and other fruits, while chemical synthesis is obtained by synthesizing from simple organic substances through a synthetic process.
When exposed to Malic acid, direct contact with skin and eyes should be avoided and care should be taken to use personal protective measures such as gloves and goggles. During use and storage, contact with organic substances, oxidizing agents and strong acids should be avoided to prevent unsafe chemical reactions from occurring. Before using it, the relevant safety instructions and operating procedures should be carefully read and followed.

Uses
It can form chelates with metal ions and can be used to remove metal corrosion products (rust). It can be used alone or in combination with other organic acids as a metal cleaner.
DL-Malic acid is a pharmaceutical grade salt of it. It is used to make antibiotics and to control the pH of bacteria cultures. DL-Malic acid kills gram-positive bacteria like Streptococcus pneumoniae and Staphylococcus aureus. It may work by stopping enzymes in these bacteria. It also stops tumors in animals.
