About

An aluminum alkoxide compound used as a precursor in personal care formulations, with potential skin and respiratory irritation concerns.

Aluminum Butoxide (CAS 2269-22-9) is an aluminum alkoxide that can release butanol upon hydrolysis. The substance carries GHS hazard statements indicating skin and eye irritation potential (H315, H319). In the EU, aluminum compounds are subject to review for their potential to cause systemic toxicity upon long-term exposure. It is not listed in EU Annex II or III for cosmetic restrictions specifically, but aluminum is subject to restriction in the EU Cosmetics Regulation (Annex III) for certain applications. Skin contact should be minimized in leave-on products.
