Downy Unstopables Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Downy is the best-performing downy unstopables brand in July 2026, moving 240,000 units across 6 ASINs for 57.1% of Top 10 volume. Lysol follows with 110,000 units (26.2%), ahead of Cascade on 70,000 units (16.7%).

With 3 brands splitting the Top 10 and 100.0% 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 $9.56 to $19.94, 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, one ASIN forced its way in: B01NBFHFZN booked 10K units at $6.72, with ▲ 0.0% MoM change. On the growth side, B0C8X76GWZ leads positive momentum with ▲ 2900.0% MoM growth on 3K units, with B06XDNB19H close behind at ▲ 250.0% MoM on 7K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
