Bath Soap Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Dove is the best-performing bath soap brand in July 2026, moving 350,000 units across 5 ASINs for 62.5% of Top 10 volume. eos follows with 60,000 units (10.7%), ahead of VALITIC on 50,000 units (8.9%).

With 6 brands splitting the Top 10 and 82.1% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $9.98 to $15.49, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, 2 ASINs forced its way in: B0B1PDDLGZ booked 40K units at $15.18, with ▲ 33.3% MoM change. On the growth side, B00MEDUKCE leads positive momentum with ▲ 1566.7% MoM growth on 10K units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
