PURPOSE:To provide a finger tip-humidifying solution containing lactic acid and a water-soluble lactic acid polymer having a low degree of polymerization and realizing the slipping stop of the finger tip due to the humidification on the counting of bills, etc., and also realizing the cleanliness of a sponge, because of being non-injurious for human bodies and exhibiting a persistent sterilizing property. CONSTITUTION:A finger tip-humidifying solution contains lactic acid (suitably L-lactic acid) and/or a water-soluble lactic acid polymer having a low polymerization degree. An aqueous solution containing the lactic acid and/or the above- mentioned lactic polymer in a concentration of 1-5% is preferable as the humidifying solution. The humidifying solution is preferably further compounded with skin-protecting agents such as 1-10wt.% of glycerol, 1-10wt.% of stearic acid and 0.1-5wt.% of tocopherol for protecting the skins. |
