FAQ

What is 2-Hydroxypropyl stearate (CAS: 1323-39-3)?

2-Hydroxypropyl stearate is a fatty acid derivative characterized by the presence of a stearic acid group attached to a 2-hydroxypropyl group. Its chemical formula is C19H38O4. It is an oily liquid with a hydrophobic stearic acid chain and a hydrophilic 2-hydroxypropyl group, making it amphiphilic. It is widely used in the cosmetics, pharmaceuticals, and food industries due to its emulsifying and stabilizing properties.

What are the main uses of 2-Hydroxypropyl stearate (CAS: 1323-39-3)?

2-Hydroxypropyl stearate is predominantly used in the cosmetics industry as an emulsifier and thickener. In the pharmaceutical field, it serves as an excipient for improving the stability and texture of dosage forms. It is also utilized in the food industry as an emulsifier and stabilizer. Additionally, it finds applications in research and development for its unique amphiphilic properties.

Is 2-Hydroxypropyl stearate (CAS: 1323-39-3) safe?

2-Hydroxypropyl stearate is considered non-toxic and safe for its intended uses in cosmetics, pharmaceuticals, and food products. However, it should be handled with care and stored in a cool, dry place away from direct sunlight. Proper protective measures, such as gloves and eye protection, are recommended when working with this substance to prevent skin contact and inhalation.

How should 2-Hydroxypropyl stearate (CAS: 1323-39-3) be stored?
