Propylene Carbonate
Ingredient Info
Propylene carbonate is a clear, odorless liquid that acts as a solvent in skincare formulations, helping to dissolve and deliver other active ingredients effectively into the skin. It's also used to improve the texture and consistency of products like ointments and serums.
Benefits
- Enhances penetration and delivery of active ingredients into the skin
- Helps maintain product stability and consistency
- Allows formulation of ingredients that would otherwise be difficult to dissolve
Potential concerns
- Generally recognized as safe for topical use, but may cause irritation in sensitive individuals at high concentrations
- Limited long-term safety data specific to skincare applications in everyday consumers
Science: Research shows propylene carbonate is effective as a solvent vehicle in topical formulations, successfully delivering active pharmaceutical ingredients like fluoride and paclitaxel through the skin with good tolerability after repeated application. However, most published data focuses on pharmaceutical rather than cosmetic skincare use.
