The 1,2hexanediol carrier is a highly effective coupling agent and is milder to the skin when applied topically to the axilla or other areas of the skin as compared to many other polyol-containing carriers. Preferred are antiperspirant compositions containing solubilized antiperspirant active.

Why it's free to use
- Filed April 26, 1999 and granted June 10, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 26, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 26, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
