1,6-HEXANEDIAMINE

Description

1,6-Hexanediamine is a versatile organic compound with significant applications in skincare and cosmetic formulations. This colorless, crystalline solid is characterized by its molecular formula C6H16N2 and features two primary amine groups at opposite ends of a six-carbon chain. In skincare, it functions primarily as a pH adjuster and emulsion stabilizer.

The ingredient's ability to neutralize acidic components makes it valuable in balancing the pH of various products, ensuring they are skin-compatible and effective. Its dual amine structure allows it to interact with both hydrophilic and lipophilic substances, enhancing the stability of emulsions and preventing separation in creams and lotions.

1,6-Hexanediamine also exhibits antimicrobial properties, contributing to product preservation and potentially offering mild antibacterial benefits in formulations. Its low molecular weight facilitates penetration into the stratum corneum, where it can aid in moisture retention and improve skin barrier function.

While generally considered safe in regulated concentrations, formulators must be cautious of potential skin irritation at higher levels. Its use is typically restricted to leave-on products where its benefits can be maximized without excessive exposure risks.
