Score, factor by factor
Concern48 / 5555 / 55
How much genuine, cited concern the ingredients carry, weighted by how much of each is likely present and whether the product stays on or rinses off. Commonly feared but low-concern ingredients cost nothing.
Transparency12 / 2020 / 20
Whether the full ingredient list, and any fragrance, are actually disclosed. An undisclosed "fragrance/parfum" blend hides its allergens and costs points.
Formulation restraint20 / 2525 / 25
Needless irritant or allergen load for the product type. A clean, purposeful formula scores well without any "free-from" theater.
PlainScore80 / 100100 / 100
The three factors summed: concern out of 55, transparency out of 20, formulation restraint out of 25. Higher is lower concern.
