Propanediol
Propanediol is a gentle, plant-derived humectant and solvent commonly used in UK skincare and haircare to help products feel silky and absorb better. It works as an alternative to propylene glycol, drawing moisture into the skin without irritation for most users. You'll find it in serums, creams, cleansers and hair treatments for its lightweight hydration and texture-enhancing properties.
How it works in skincare
In cosmetics and skincare, propanediol functions as a humectant that attracts and binds water to the skin’s surface, improving hydration and helping active ingredients penetrate more effectively. It also acts as a solvent and viscosity modifier, giving formulas a smooth, non-sticky glide and enhancing the overall sensory feel of lotions, serums and hair products. Being highly water-soluble and compatible with many common cosmetic ingredients, it is frequently chosen as a safer, more skin-friendly alternative to synthetic glycols.
