What is PROPYLENE GLYCOL MONOSTEARATE?
Chemical properties
Propylene glycol monostearate has a bland odor and taste. It is not a single chemical entity, but is a mixture of propylene glycol mono- and diesters of stearic and palmitic acids. For a detailed description, refer to Burdock (1997).
Preparation
Produced commercially by catalytic transesterification between propylene glycol and a hydrogenated vegetable oil such as soybean oil.
Definition
ChEBI: 2-Hydroxypropyl stearate is a fatty acid ester.
