Malic acid | CAS No. 6915-15-7

Q: What is Malic acid (CAS: 6915-15-7)?

Malic acid (CAS: 6915-15-7) is a naturally occurring dicarboxylic acid with the chemical formula C4H6O5. It is commonly found in fruits like apples and grapes, and is known for its sour taste and role in metabolic processes. Malic acid is a white crystalline powder, highly soluble in water, and exhibits weak acidity. It is widely used in various industries due to its versatile chemical properties.

Q: What are the main uses of Malic acid (CAS: 6915-15-7)?

Malic acid (CAS: 6915-15-7) is primarily used in the food industry as a souring agent, preservative, and flavoring component. It also finds applications in pharmaceuticals for drug formulation and as a chelating agent. In the cosmetic industry, it is used in skincare products for its exfoliating properties. Additionally, it is employed in research, industrial processes, and as a pH regulator in chemical manufacturing.

Q: Is Malic acid (CAS: 6915-15-7) safe?

Malic acid (CAS: 6915-15-7) is generally recognized as safe (GRAS) when used in food and cosmetic applications. However, high concentrations may cause skin or eye irritation. In industrial settings, proper handling and protective equipment are recommended to avoid inhalation or contact. It complies with safety standards set by regulatory bodies, including OSHA and EPA, for appropriate use and storage.

Q: How should Malic acid (CAS: 6915-15-7) be stored?

Malic acid (CAS: 6915-15-7) should be stored in a cool, dry, and well-ventilated area, away from direct light. It requires airtight containers to prevent moisture absorption and maintain stability. Storage conditions should be controlled to avoid humidity, as exposure can degrade its quality. Keep it in a designated chemical storage area to ensure safety and prolong shelf life.
