Tampon absorbency denominations correspond to tampon absorbency (“droplet”) categories of the European Disposables and Nonwovens Association's tampon code of practice (3) as follows: “mini,” 2 droplets (6- to 9-g absorbency); “normal,” 3 droplets (9- to 12-g absorbency); “super,” 4 droplets (12- to 15-g absorbency); “super plus,” 6 droplets (18- to 21-g absorbency). The first three of these correspond roughly to “regular,” “super,” and “super plus” absorbencies, respectively, according to FDA labeling requirements in the United States; absorbencies higher than 18 g are not covered by U.S. regulations (9).
Total percentage figures could exceed 100% because respondents could report using more than one absorbency of tampon.
