Colgate · Optic White Stain Fighter Clean Mint Paste Teeth Whitening Toothpaste
Three independent Greenlens lenses read the same 13 ingredients and land 34 points apart. That gap is not an error. Each lens asks a different question, and this page shows every answer, ingredient by ingredient, blended into nothing.
Our sources have reference data on all 13 listed ingredients. Our sources can only speak to ingredients they recognize — either flagged by an authority or known to be a common, well-characterized ingredient. An uncharacterized ingredient is a gap in our data, not a clean bill of health: a quiet safety scan over ingredients we can’t place is a weaker signal than one over ingredients we can.
Independent
The regulatory baseline. Follows EU cosmetic law: prohibited and restricted ingredients cost points, and allergen labelling is capped so it cannot tank a score on its own.
Flagged 4 of 13 ingredients: 1 restricted, 2 of concern, 1 regulated allergen.
Independent
The strict lens. Flags any ingredient with a listed hazard trait (SIN List, IARC, Prop 65), even when regulators still permit it.
Flagged 1 of 13 ingredients on hazard grounds: 1 strong sensitizer. Score capped: a strong sensitizer is present.
Independent
The lenient lens. Trusts dose and regulation: permitted ingredients kept within their legal caps are tolerated, and only genuinely prohibited substances take a big hit.
Flagged 1 of 13 ingredients: 1 restricted (within-limit).
These lenses disagree. A split of 34 points crosses our disagreement threshold (20). We keep every verdict and never average them; the table below is where the split comes from.

The overall ring on the product page is the weighted mean of the four pillars using your weights, computed fresh on every visit and never stored. How each lens's reference lists were built, penalty by penalty, is on the methodology page.
