Propanediol
A multifunctional, 100% plant-derived humectant and solvent that helps maintain hydration, improve skin feel and support the effective incorporation of complementary ingredients into a formulation.
Why This Ingredient Matters
The performance of a skincare formula depends not only on which active ingredients it contains, but also on how effectively those ingredients are incorporated. Propanediol is a multifunctional ingredient that contributes to both the skincare experience and the technical performance of a formulation.
Produced through plant-based fermentation, it provides an alternative to conventional petroleum-derived glycols.
As a humectant, Propanediol helps attract and retain moisture, supporting skin hydration and softness. As a solvent, it can help dissolve selected ingredients that may be difficult to incorporate into water-based formulas. It can also contribute to a smooth, elegant texture and support the performance of complementary preservation ingredients.
These combined properties make Propanediol an especially valuable supporting ingredient in advanced skincare.
Why Formulation Matters
Selecting an effective active ingredient is only part of creating a sophisticated skincare product. That ingredient must also be compatible with the formula and incorporated in a way that supports stability, texture and intended performance.
Some cosmetic ingredients have limited solubility in water, presenting challenges for formulators. Propanediol can help address certain solubility challenges while contributing hydration and improving the sensory character of the finished product. Supplier research has explored its usefulness as a solvent for selected skincare ingredients, including ferulic acid, ascorbic acid and allantoin.
These findings demonstrate the importance of the surrounding formulation, although solubility performance does not by itself establish improved skin penetration or clinical efficacy. Propanediol also illustrates how a single ingredient can contribute to multiple formulation goals.
Formulation Changes Everything.
How Luzern Uses It
Luzern incorporates plant-derived Propanediol into selected skincare formulations for its complementary hydration, solvent and sensory properties.
It helps support moisture retention, ingredient incorporation and an elegant skin feel. Depending on the formulation, it can also contribute to the performance of complementary preservation ingredients. Its multifunctional character reflects Luzern's approach to selecting ingredients that contribute meaningfully to the complete formula.
