If you grew up in the 80s or early 90s, you can probably still hear it. "You're not fully clean unless you're Zestfully clean." Zest has been around since Procter & Gamble introduced it in the 1950s, and it's still on the shelf today, usually in a big multipack for not much money. So is Zest a good soap? For an inexpensive everyday bar, yes. Here's what's in it and how it compares.
What's in a bar of Zest
The current Zest Aqua bar lists sodium tallowate and/or sodium palmate first, then sodium cocoate and/or sodium palm kernelate, water, glycerin, a blend of fatty acids and fragrance. In plain English, it's true soap made from tallow (beef fat) and/or palm oil, plus coconut or palm kernel oil, with added scent.
That's a little different from the Zest some people remember. The original was a combination bar that mixed soap with synthetic detergent, and some versions were reformulated as all soap after a relaunch in the 2000s. If it matters to you which is which, read the label on the pack you're holding.
Is Zest soap antibacterial?
We couldn't find any current Zest bar labeled antibacterial. Antibacterial soaps carry a Drug Facts panel listing an active ingredient, and the Zest bars we checked don't have one. Retailers describe it as a deodorant bar that washes away germs, which is what all soap does when you scrub and rinse.
That's not a knock. The FDA has said there's no evidence that consumer antibacterial soaps work better than plain soap and water for everyday washing, and in 2016 it pulled triclosan and a long list of similar ingredients from them.
Who makes Zest now?
Procter & Gamble sold the North American rights to Zest in 2011 to High Ridge Brands, which is still the name on the label. High Ridge has changed hands since, most recently in 2024. Outside North America, the brand belongs to Unilever.
Where Zest wins
Price, by a mile. Target sells a 12-pack of 4 ounce Zest Aqua bars for $6.79, which is under 60 cents a bar. It's easy to find, and if you like that bright, clean Zest smell, nothing else quite matches it.
Where we'd make a different case
We make our bars by hand in small batches with organic plant oils, no tallow. Our scents range from bourbon and burnt lumber to none at all (our Castile Soap is fragrance-free). We cost a lot more than Zest, and we'd never pretend otherwise. What you get for the difference is a short ingredient list built on plant oils and a bar made by people you can actually email.
