sodium carboxymethylcellulose
Sodium CMC is the most industrial name on the gentlest molecule — chemically dressed cellulose that thickens, binds, and exits unchanged.
Also appears on labels as: cellulose gum · carboxymethylcellulose · sodium cmc · e466
What it is
Cellulose — plant fiber — chemically modified to dissolve in water. The label's scariest-looking word ('cellulose gum' is the same substance in softer type) is functionally one of its most inert: unfermented, unabsorbed, in and out as viscosity.
Why it's in pet food
Moisture control and binding in wet foods and dental chews, at fractions of a percent. Its long human-food history (ice cream, toothpaste) is a tolerance record, not a warning.
How Bowlmark scores it
Scores are deterministic math over the printed label — the rules below apply to every product identically, and nothing estimates or fills in a blank.
Neutral: no deduction, no flag. A good calibration page for chemical-name anxiety: the engine's deductions target substances with adverse literatures and disclosure games, not syllable counts — and eleven-syllable cellulose is still cellulose.
