FAQ

What is propylene glycol alginate (CAS: 9005-37-2)?

Propylene glycol alginate is a sodium salt of alginic acid esterified with propylene glycol. It has the chemical formula C6H10O22Na6 and is characterized by its thickening, stabilizing, and emulsifying properties. Commonly used in food, pharmaceutical, and industrial applications, it is a biodegradable and non-toxic compound.

What are the main uses of propylene glycol alginate (CAS: 9005-37-2)?

Propylene glycol alginate is widely used as a food additive to improve texture and stability in products like ice cream and dairy items. In pharmaceuticals, it serves as a binder and excipient. Industrially, it is applied in textiles and coatings. It is also used in research for studying gelling agents and in cosmetic formulations for viscosity control.

Is propylene glycol alginate (CAS: 9005-37-2) safe?

Propylene glycol alginate is generally recognized as safe (GRAS) by the FDA for food use. It has low toxicity and is non-irritating when handled properly. However, inhalation or prolonged skin contact should be avoided. Safety standards ensure it meets regulatory requirements for industrial and pharmaceutical applications.

How should propylene glycol alginate (CAS: 9005-37-2) be stored?

Propylene glycol alginate should be stored in a cool, dry place away from light and moisture. It is stable at room temperature but should be kept in airtight containers to prevent degradation. Avoid exposure to high humidity or extreme temperatures to maintain its effectiveness and shelf life.
