Methylpropanediol Description
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.
Methylpropanediol 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.
In fragrance formulations, methylpropanediol can prolong scent intensity on the skin.
As a raw material it is clear, colorless liquid.
During 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.
