FAQ

What is Ethylene glycol monostearate (CAS: 9004-99-3)?

Ethylene glycol monostearate is a synthetic ester compound with the chemical formula C18H34O4. It is a white, waxy solid that is insoluble in water but soluble in organic solvents. This compound is commonly used as a surfactant, emulsifier, and lubricant in various industries due to its ability to reduce surface tension and improve compatibility between substances.

What are the main uses of Ethylene glycol monostearate (CAS: 9004-99-3)?

Ethylene glycol monostearate is widely utilized in pharmaceuticals as a stabilizer and emulsifier, in the food industry as a fat substitute, and in industrial applications for its lubricating and conditioning properties. It is also employed in research for developing formulations and in the production of cosmetics and personal care products for texture enhancement.

Is Ethylene glycol monostearate (CAS: 9004-99-3) safe?

Ethylene glycol monostearate is generally considered safe when used in accordance with recommended guidelines. However, it should be handled with appropriate protective measures, such as gloves and goggles, to avoid skin or eye contact. Safety data sheets (SDS) indicate that it is non-toxic in normal use but may cause irritation if misused. It is approved for use in food and pharmaceutical applications by regulatory bodies like the FDA and EMA.

How should Ethylene glycol monostearate (CAS: 9004-99-3) be stored?

Ethylene glycol monostearate should be stored in a cool, dry place away from direct sunlight. It is stable under normal storage conditions but should be kept in a sealed container to prevent moisture absorption. Avoid exposure to high temperatures and humidity to maintain its quality and effectiveness over time.
