ciccum Working notes from the formulation desk: comparison tables, certification record checks, and ingredient-level verdicts that sit behind our regular coverage. Each entry names exact products and links the primary documents it was checked against.
Surfactant class and published pH check directly against a cleanser's INCI list, fragrance/essential-oil claims often don't survive a line-by-line read, and post-wash tightness stays an inference — never a measured fact — across all seven sensitive-skin cleansers checked here.
