1,2-Hexanediol is a six-carbon diol whose two hydroxyl groups sit on adjacent carbons. It has a mild self-association tendency, forming micelle-like aggregates in solution — a property exploited both in personal-care formulation and in surfactant research.
This compound is manufactured into cosmetic and personal-care formulations as a multifunctional ingredient — providing humectant (moisture-retaining) properties while also boosting the effectiveness of preservative systems, which has made it a popular alternative/supplement to traditional preservatives in modern formulations.
