ALUMINUM BUTOXIDE
Description
Aluminum butoxide is a versatile organometallic compound widely used in skincare formulations and cosmetic products. This aluminum alkoxide, with the chemical formula Al(OC4H9)3, serves as a precursor in sol-gel processes and acts as an effective cross-linking agent. In skincare, it functions primarily as a thickening and stabilizing agent, enhancing the texture and shelf-life of various products.
The compound's ability to form protective films on the skin makes it valuable in sunscreens and barrier creams. It contributes to improved SPF efficacy and water resistance in sun protection formulas. Aluminum butoxide also exhibits mild astringent properties, potentially benefiting oily and acne-prone skin types by temporarily tightening pores and reducing excess sebum production.
In addition to its functional roles, aluminum butoxide can act as a delivery system for other active ingredients, enhancing their penetration and efficacy. Its low toxicity profile and stability in various pH environments make it suitable for a wide range of skincare applications. However, formulators must consider potential sensitivities in individuals with aluminum allergies when incorporating this ingredient into products.
