Product overview
Irish Spring Original Deodorant Bar Soap: What to Know
Unlike the syndet bars on this list, Irish Spring is a traditional saponified soap. Colgate-Palmolive's own SmartLabel ingredient disclosure for this product line lists a soap base of sodium tallowate and/or sodium palmate plus sodium cocoate and/or sodium palm kernelate, along with glycerin, fragrance, and colorants including titanium dioxide and D&C/FD&C green dyes -- the ingredients responsible for its recognizable green color and scent.
Irish Spring's own site markets the bar with a '12-hour' freshness/deodorant claim and describes the formula as 98% naturally derived and free of parabens, phthalates, and gluten. These are the brand's own stated claims; we did not independently test odor-control duration. Irish Spring has also been a long-running fixture of the US drugstore soap aisle under Colgate-Palmolive, which is a track-record data point rather than a skin-benefit claim.
The listing referenced here is a 2-bar pack at 3.2 oz per bar -- a relatively small pack. Irish Spring sells the same 'Original' scent in configurations ranging from 2 bars up to 20-plus bar cases, alongside other scent lines (Icy Blast, Aloe Mist, Moisture Blast) in very similar green packaging.
