Stearic Acid
What is Stearic Acid?
Stearic Acid is a saturated fatty acid commonly found in animal and plant fats. It is often derived from palm or coconut oil, and can also be synthetically produced. This white, waxy solid is known for its multiple uses in various industries.
In cosmetics and personal care products, Stearic Acid is used as a surfactant and emulsifier, helping to improve texture and stability. It is also used in supplements as a coating ingredient to aid in the delivery of active substances. The health evidence on Stearic Acid is largely neutral, with no major concerns reported at typical exposure levels.
When you see Stearic Acid on a label, it is usually serving a structural or textural purpose, making products easier to use or increasing shelf life.
Commonly found in: Brain Supplements, Hair & Skin Care, Deodorants, Makeup
Stearic Acid is generally recognized as safe (GRAS) by the FDA for its intended uses.
Research indicates that Stearic Acid is metabolically inert compared to other fatty acids and generally not associated with cardiovascular risk.
Stearic Acid can be derived from both animal and plant sources. Vegans may prefer products specifying plant-derived sources.
