The wall-mounted dispenser for liquid soap has a separable reservoir with an outlet valve. The dispenser further includes a main body with a second outlet valve. When the reservoir is mounted to the main body, a metering chamber is defined between the two outlet valves. The dispensing function is experienced by pushing in a plunger which temporarily decreases the chamber volume and forces the main body outlet valve to open temporarily, thus dispensing a charge of liquid soap. As the plunger is released, a spring return pushes the plunger out, decreasing pressure in the metering chamber, which is equalized as the first outlet valve temporarily opens, admitting a next charge of liquid soap from the reservoir to the metering chamber. The reservoir is replaced by pushing in a resilient release, but the resilient release is preferably normally provided with a stop which must first be moved out of the way. This is to prevent the user from accidentally disconnecting the reservoir when what is really wanted is a dispensation of soap. Should the reservoir be disconnected, pushing in and releasing the plunger will not result in the first outlet valve to open, because pressure will not be lowered in the metering chamber when the plunger is released.

Disclosed is a viscous liquid soap composition which comprises 8 to 11 parts by weight, per 100 parts by weight of the total composition, of a potassium oleate soap, and 3.5 to 5.5 parts by weight, per 100 parts by weight of the total composition, of a higher saturated fatty acid potassium soap, and then the total amount of said two soaps being 13.5 to 15.5 parts by weight per 100 parts by weight of the total composition, 5 to 7 parts by weight, per 100 parts by weight of the total composition, of a fatty acid monoethanolamide and 9 to 11 parts by weight, per 100 parts by weight of the total composition, of a polyhydric alcohol selected from the group consisting of propylene glycol and glycerin, with the remainder being water. This soap composition has such a viscosity-temperature correlation that the viscosity is highest at room temperature or at a temperature in close proximity to room temperature. Furthermore, in this soap composition, the viscosity is hardly changed with the lapse of time.
