Methylpropanediol

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.
