Salt is how a formulator adjusts a product's salt balance toward the body's own. Used carefully it helps; used as a cheap thickener it is one more thing pushing osmolality up. Its presence is neutral information on its own.
WHO/UNFPA guidance suggests personal lubricants stay at or below 380 mOsm/kg, and ideally never exceed 1,200 mOsm/kg, because high-osmolality formulas pull water out of the thin cell layer lining the vagina and rectum. Ingredient lists do not print osmolality, so the practical move is to look for the number on the product page or ask the manufacturer.
It is widely used and is not a usual concern on its own. Salt is how a formulator adjusts a product's salt balance toward the body's own. Used carefully it helps; used as a cheap thickener it is one more thing pushing osmolality up. Its presence is neutral information on its own.
Its role is ph / tonicity adjuster. Widely used and not a usual irritation flag on its own. Individual formulas and individual bodies still differ.
Somewhat — it contributes, though less sharply than glycerin or PEG.

Yes. An ingredient list shows what is in a formula, never how much, and two products sharing an ingredient can behave completely differently. The product's own label and instructions always take priority over a general category rating.
