Mechanism of Action
Functioning primarily as a solvent, Hexylene Glycol efficiently dissolves other ingredients within a formulation, ensuring a homogenous blend and enhanced product performance. As a humectant, it actively attracts and retains moisture in the skin, promoting improved hydration and a more supple complexion. Additionally, it acts as an emulsifier to blend immiscible liquids, a viscosity-decreasing agent to refine product texture, and a stabilizer, while also possessing antimicrobial properties that can inhibit microbial growth.

Stability
Hexylene Glycol itself has a neutral pH of 7.0 and is stable under normal conditions. Aqueous solutions of hexylene glycol have shown stability over a 7-day period. As a hygroscopic substance, it absorbs moisture from the air, requiring formulations to be stored in well-sealed containers, away from high heat or open flames.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded Hexylene Glycol is safe for use in cosmetics, reaffirming this in 2004. It is permitted by the FDA as an indirect food additive. Generally, it presents a low risk of skin irritation or sensitization and is not known to be comedogenic. While some historical reports noted irritation at higher concentrations, recent guideline studies indicate it has a low potential to irritate the skin and only causes slight, reversible eye irritation.
