How is "modified cellulose" counted, and which filed spellings feed it?
Each NIH DSLD label enters once, whatever its spelling; case and repeated spaces are normalized and known synonyms merged, using the snapshot 2026-08-10 and normalization dated 2026-10-17. This group has 3 to 9 labels, so its page is shorter: the same label numbers, fewer charts.
