FAQ

What is Ethyl stearate (CAS: 111-61-5)?

Ethyl stearate (CAS: 111-61-5) is a saturated fatty acid ester with the chemical formula C20H40O2. It is a white, waxy solid that is odorless, insoluble in water, and soluble in organic solvents. Ethyl stearate is commonly used as a lubricant, emollient, or plasticizer due to its stable chemical properties and non-reactive nature.

What are the main uses of Ethyl stearate (CAS: 111-61-5)?

Ethyl stearate (CAS: 111-61-5) is widely used in pharmaceuticals as a base for suppositories and ointments, in the cosmetics industry for skin care products, in food as an emulsifier and texturizer, and in research for lipid-based studies. It also serves as a lubricant in machinery and a component in candle manufacturing.

Is Ethyl stearate (CAS: 111-61-5) safe?

Ethyl stearate (CAS: 111-61-5) is generally considered safe when handled properly. It has a low toxicity profile and is non-irritating to skin and eyes. However, prolonged inhalation of its vapors or ingestion may cause mild health risks. Always follow safety standards like OSHA guidelines to ensure safe handling and storage.

How should Ethyl stearate (CAS: 111-61-5) be stored?

Ethyl stearate (CAS: 111-61-5) should be stored in a cool, dry place below 25°C, away from direct light. Keep it in airtight, moisture-proof containers made of glass or metal to maintain stability and prevent degradation. Ensure proper ventilation to avoid accumulation of vapors in enclosed spaces.
