The present invention is a cosmetic or dermatological preparation for use with a dispenser system that includes at least 0.01% by weight of one or more hydrocolloids. The preparation is particularly suitable with a dispenser comprising an essentially cylindrical container and an inner container wall for housing a cosmetic or dermatological preparation; a follow-up plunger on a base side of the dispenser, which is capable of being slidably displaced on the inner container wall under the pressure of the ambient atmosphere; a head section on a top end of the dispenser that can be slidably displaced in relation to the container and that comprises a dispensing channel, the dispensing channel capable of being connected in a communicating manner to the container; a manually actuable delivery device comprising a variable-volume delivery chamber, a delivery element that can be displaced longitudinally in relation to the container and the head section, comprising a delivery plunger that can be slidably displaced within the delivery chamber and a delivery stem connected to the delivery plunger, and a delivery channel circumferentially enclosed by the delivery stem and comprising a delivery-channel inlet opening communicating with the delivery chamber and a delivery-channel outlet opening. The delivery channel outlet opening is capable of being moved into an open position relative to the dispensing channel by displacing the delivery element. |
