What is Stearic Acid?

Stearic acid is a naturally occurring fatty acid commonly found in animal and plant fats. It is usually derived through the saponification process from fats and oils.

Stearic acid is also used in dietary supplements and pharmaceuticals to improve texture and consistency. The health evidence suggests that it is generally considered safe for topical use and consumption.
