Propanediol is a lightweight humectant—a molecule that draws water into the skin to keep it hydrated. It's also used in cosmetic formulations as a solvent and preservative booster, helping products stay stable and feel smooth on the skin.
Benefits
Hydrates and moisturizes the skin
Improves product texture and spreadability
Helps preserve formulations naturally
Science: Propanediol can be produced through bio-based fermentation (from glycerol using microorganisms), making it an environmentally friendly alternative to traditional chemical synthesis. It is widely recognized as safe in cosmetic and food applications, with established use as both a humectant and preservative enhancer.
Caprylic/Capric Triglyceride is a lightweight oil derived from coconut that acts as an emollient and helps formulations blend smoothly. It softens skin and reduces water loss by creating an occlusive barrier on the skin's surface.
Benefits
Improves skin hydration and reduces transepidermal water loss (TEWL)
Lightweight, non-greasy feel compared to heavier oils
Helps deliver other active ingredients deeper into the skin
Smooth, silky texture in skincare formulations
Science: Research shows that emulsions containing 15% caprylic/capric triglyceride significantly increase skin hydration and reduce water loss in healthy subjects. The ingredient is also used as an effective carrier oil in nanoemulsions to enhance penetration of active compounds into skin.
