How many US lubricants and vaginal moisturisers publish a full ingredient list, a pH figure, or an osmolality figure anyone could check — counted from labels read at source, with the URL and date on every record. Water-borne products only. The one number that cannot be worked out from a label. The claim cannot be checked, compared to a reference range, or found wrong by a reader. Cheap to measure, cheap to print. Absence is a choice, not a limit. Kept in the catalog and scored as unanswered, never as a pass. The rest had to be read from a shop listing or an aggregator the maker does not control. 3 of 25 water-borne products publish an osmolality figure. Osmolality is the number most often cited in guidance about lubricant and tissue irritation, and it is the one number that cannot be worked out from an ingredient list — it is measured. Where a maker does not publish it, nobody outside that company can check it, including us. This count is a measure of what is publicly checkable, not of what is safe.
