Aluminum Stearate
What is Aluminum Stearate?
Aluminum Stearate is a compound formed from stearic acid and aluminum, often used in industrial applications. It is typically produced by reacting sodium stearate with aluminum chloride.
In consumer products, it is primarily used as a thickener and stabilizer, especially in cosmetics and sunscreens. The scientific evidence on its health effects is limited, and it is generally considered to be safe in the small quantities used in these products.
When you see it on a label, it's usually serving to improve the texture or stability of the product, particularly in formulations designed to stay spreadable over the skin.
Commonly found in: sunscreen, cosmetics, personal care products
Aluminum Stearate is generally recognized as safe (GRAS) by the FDA for use in consumer products.
Research is limited, but there is no strong evidence pointing to significant health risks at typical exposure levels in consumer products.
Aluminum Stearate is not derived from animal products, so it is generally considered vegan-friendly.
