What does this ingredient do in an antiperspirant?
A glycol solvent (also called hydroxypropyloxypropanol or 4-oxa-2,6-heptanediol). INCI functions: solvent, viscosity controlling, fragrance and a functional excipient of perfume compositions.
Part of a system, not a label in isolation
In the catalogue it appears in roll-ons and deodorant sprays, including foot and shoe sprays: it dissolves other ingredients, fragrance among them, and keeps them in the base. It does not reduce sweating.
The CIR concluded that Dipropylene Glycol is safe in the present practices of use (1985 assessment, conclusion reaffirmed in 2004); the CIR summary table lists use concentrations of up to 50%.
It is used as a solvent; an individual reaction to the finished product is possible.
Not to be confused with Propylene Glycol: propylene glycol is a separate INCI name, while dipropylene glycol is a compound made of two propylene glycol units.
