- Description – Properties – Advantages
Stearin is a triglyceride, a pearly white solid substance obtained by saponification of natural vegetable or animal fats. It is also called tristearin or stearic acid (C57H110O6).
Stearin is odorless and tasteless. At room temperature, it forms a white solid. Its melting point is around 70 ° C.
This saturated fatty acid naturally present in animal and vegetable fats is used mainly as a consistency factor to thicken preparations, enrich and stabilize emulsions and harden mixtures.
It is insoluble in water and very slightly soluble in ethanol. It is a biodegradable substance.
