Abstract
A water soluble lubricant for condoms includes at least a sliminess agent and a penetrating agent, and optionally, a humectant. The water soluble lubricant has a good penetrating feature to the wound up part of a condom, does not whiten the surface appearance of a condom, and provides sliminess and wettability to a condom to which the lubricant is applied. Water soluble penetrating agents which have good penetrating effect to the wound up part and do not whiten the appearance of a condom include sodium-lactate and trimethylglycine. Humectants which provide a condom with good wettability include glycerin and propyleneglycol. The water soluble sliminess agent which provides a condom with sliminess may be pullulan.
