Ethylhexylglycerin is a preservative and antimicrobial ingredient used to prevent bacterial growth and extend shelf life in skincare products. It's a multifunctional ingredient that helps keep formulations stable and free from contamination.
Benefits
Prevents bacterial contamination in products
Helps extend product shelf life
Works synergistically with other preservatives for enhanced protection
Potential concerns
May not be effective against all bacterial species (notably some Pseudomonas aeruginosa strains)
Preservative-related sensitization possible in sensitive individuals, though uncommon
Science: Research shows ethylhexylglycerin has broad antimicrobial activity against many common cosmetic contaminants, though effectiveness varies by bacterial species. Studies demonstrate it can work synergistically with other preservative components to enhance biofilm inhibition.
Glycerin is a naturally-derived humectant—a substance that draws water into the skin from the air and deeper skin layers. It's a common moisturizing ingredient used across skincare products to improve hydration and skin softness.
Benefits
Increases skin hydration by attracting moisture to the outer layers
Helps maintain skin barrier function and protects against dryness
Generally well-tolerated and suitable for most skin types, including sensitive skin
Science: A comprehensive safety assessment by the Cosmetic Ingredient Review Expert Panel concluded that glycerin is safe as used in cosmetics. Research supports its role as a humectant and skin conditioning agent, and it has been studied as part of broader skincare treatments for conditions like seborrheic dermatitis.
