METHYLPROPANEDIOL
Methylpropanediol is the label name used here for the compound 2-methyl-1,3-propanediol. It is a defined chemical substance rather than an oil, plant extract or fragrance, so the same name can occur in very different cosmetic categories without pointing to a botanical raw material.
METHYLPROPANEDIOL: what it is
Methylpropanediol is the label name used here for the compound 2-methyl-1,3-propanediol. It is a defined chemical substance rather than an oil, plant extract or fragrance, so the same name can occur in very different cosmetic categories without pointing to a botanical raw material.
The term diol refers to two alcohol groups in the substance's structure. The methyl part of the name distinguishes it from other propanediols: they may look similar on a label, but they are not the same compound and should not be treated as interchangeable when comparing ingredient lists.
METHYLPROPANEDIOL: what it does in cosmetics
In cosmetics, Methylpropanediol works as a solvent. In practical terms, it helps dissolve and keep certain components distributed in the liquid phase, supporting a preparation in which those components remain in solution.
That job concerns the product base, before any expectation of a result on skin or hair. Seeing it on a label points to support for incorporating other components into the preparation; the word solvent on its own is not a treatment claim.
