[0101] The cleansing preparations listed above were prepared and the properties thereof examined in a panel of experts on washing. The following procedure was applied:

Preparation:

[0102] Participants' forearms were cleansed using a standard shampoo, dried and acclimatized for 10 minutes. Then, the inner side of the forearm was held under running water for 2 seconds, and 0.5 ml of the preparation to be tested was applied to a 3 cm diameter circular area on the inner forearm. Before spreading, the spreading hand was held under running water for 2 seconds. Then the fingers were spread to allow water to drip off. The preparation was then spread with 2 fingers of the spreading hand in circular motions (5 cm in diameter) at 90 bpm (beats per minute), the slipperiness being assessed after 5 circles. A scale of values ranging from 1 to 5 is specified as a scalar, where 1 means not slippery and 5 means highly slippery.

[0103] Each preparation was analyzed 6 times by different experts. The mean values obtained for slipperiness are listed in the following table:

[0104] Consequently, it has been found that the cleansing preparation according to the invention has a significantly increased slipperiness when spread on wet skin on which a film of product has formed.
