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

Mrs. MEYER'S is the best-performing soap refill brand in July 2026, moving 140,000 units across 4 ASINs for 33.3% of Top 10 volume. Dawn follows with 100,000 units (23.8%), ahead of Amazon Basics on 90,000 units (21.4%).

With 5 brands splitting the Top 10 and 78.6% 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 $4.46 to $8.14, 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. On the growth side, B07SGNKW9B leads positive momentum with ▲ 300.0% MoM growth on 4K units, with B0CC6HSNRD close behind at ▲ 200.0% MoM on 6K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
