Polyoxyethylene (25) propylene glycol stearate (CAS 37231-60-0)

Polyoxyethylene (25) propylene glycol stearate functions as an emulsifier and stabilizer in experimental formulations. It acts by reducing the surface tension between different components, allowing them to mix more easily and form stable emulsions. At the molecular level, the polyoxyethylene portion of the molecule is hydrophilic, meaning it has an affinity for water, while the propylene glycol stearate portion is lipophilic, with an affinity for oils and fats. This dual nature allows Polyoxyethylene (25) propylene glycol stearate to effectively bind water and oil-based ingredients together, preventing them from separating. In this way, it plays a role in maintaining the consistency and stability of experimental formulations, ensuring that they remain homogeneous and do not undergo phase separation. The presence of polyoxyethylene (25) propylene glycol stearate can contribute to the overall texture and feel of the formulation, enhancing its sensory properties for experimental purposes.
