FAQ

What is CAPS (CAS: 1135-40-6)?

CAPS, or Caprylic Acid (CAS: 1135-40-6), is an 8-carbon saturated fatty acid with the chemical formula C8H16O2. It is a colorless, viscous liquid with a faint, fatty odor, commonly used in various industries due to its emulsifying and solubilizing properties. CAPS is also known as octanoic acid and is naturally found in animal fats and plant oils.

What are the main uses of CAPS (CAS: 1135-40-6)?

CAPS (CAS: 1135-40-6) is widely used in pharmaceuticals as a surfactant and solubilizing agent, in the food industry as a flavoring agent (E470c), and in cosmetics for its emulsifying capabilities. It also serves as an industrial chemical for soap and detergent production, and in research for organic synthesis and as a model compound for studying fatty acid behavior.

Is CAPS (CAS: 1135-40-6) safe?

CAPS (CAS: 1135-40-6) is generally considered safe when used in compliance with safety standards, but proper handling is required. It may cause mild skin or eye irritation, so protective measures like gloves and safety goggles are recommended. Inhalation of vapors should be avoided, and safety data sheets (SDS) should be consulted for specific guidelines on exposure limits and emergency procedures.

How should CAPS (CAS: 1135-40-6) be stored?

CAPS (CAS: 1135-40-6) should be stored in a cool, dry, and well-ventilated area, away from direct light and heat sources. It is typically kept in airtight containers to prevent moisture absorption and oxidation. Storage conditions should maintain temperatures below 25°C and avoid high humidity. Ensure proper labeling and follow safety protocols for flammable and reactive materials.
