Aluminum Stearates
What is Aluminum Stearates?
Aluminum stearates are compounds formed from the reaction of aluminum salts and stearic acid. They are typically white, waxy, odorless powders used in a variety of products.
In cosmetics and personal care products, aluminum stearates are used as thickening agents and to improve the texture of formulations. In industrial applications, they serve as lubricants or release agents. Health evidence on aluminum stearates is limited, but they are generally considered safe for topical use in cosmetics, although there is some concern about their accumulation due to environmental exposure.
When seeing aluminum stearates on a label, it is usually acting to enhance texture or consistency, especially in lotions and creams.
Commonly found in: body lotions, creams, cosmetics, industrial lubricants, release agents, paint thickeners
What to watch
- There is potential concern regarding cumulative exposure from multiple sources, but high-level exposure is unlikely in personal care products.
Benefits
- Used to improve texture and stability in products without contributing to fragrance or color.
Aluminum stearates are allowed in cosmetics and personal care products without restrictions in the U.S.
Research into long-term health effects of aluminum compounds is ongoing, with some studies suggesting the need for monitoring cumulative exposure.
Aluminum stearates may be derived from animal sources, so their vegan status depends on the source of the stearic acid used.
Scout's take
Aluminum compound used as stabilizer/anti-caking. Bound form is generally inert but cumulative aluminum body burden is debated.
