Irish Spring is an American brand of deodorant soap owned by Colgate-Palmolive.

[citation needed] In addition, in 2011, Irish Spring deodorant was reintroduced as part of Colgate-Palmolive's Speed Stick brand of products.

[citation needed] In 1986, the soap changed its formula, included a different scent, and added skin conditioners.

[citation needed] The soap underwent another formula change in February 2022, together with the renaming of the original variant to "Original Clean," and debuted with a new logo and newly redesigned packaging designed by Chase Design Group.

This change in formulation resulted in another new scent and the addition of flaxseed oil to the bar form of the soap, which prompted some heavy backlash from consumers who preferred the scent and lather of the previous formula that had been used for over 30 years.
