What Is Methylpropanediol?
Methylpropanediol is a synthetic ingredient that functions as solvent for difficult to dissolve materials, including certain powders and preservatives. In a skin care formula, it can enhance the absorption of ingredients such as salicylic acid for better penetration and efficacy.\n\nMethylpropanediol also has pronounced hydrating properties that can leave a smooth, dewy finish on skin. It is sometimes used as part of preservative blend where it helps boost the effectiveness of preservatives, so a lower amount of them is necessary.\n\nIn fragrance formulations, methylpropanediol can prolong scent intensity on the skin.\n\nAs a raw material it is clear, colorless liquid.\n\nDuring their evaluation in June 2018, the panel of experts for the Cosmetic Ingredient Review council recognized methylpropanediol as a safe ingredient as traditionally used in cosmetic in products.
