Claim Text:
1. A topical isotonic gel lubricant for application to a human vagina that has vaginal secretions and cells, the lubricant comprising: an aqueous isotonic gel formed substantially of water and plural salts, with the salts chosen to match those present in the vaginal secretions and, thereby, make the lubricant isotonic with respect to the vagina; preselected lactic acid having a racemic index in a range of about 50% L/50% D and being present at a concentration of 1±0.5% by weight; wherein the lubricant is formulated to have a pH in the range of 3.5±0.3%; and wherein the isotonic gel, preselected lactic acid, and pH range are effective to lubricate a human vagina in such a way that minimizes the possibility that the cells of the vagina release fluid to dilute the lubricant, thereby minimizing the possibility of the death of the cells, damage to the vagina, or dryness of the vagina.
