The invention concerns cosmetic compositions containing, in a cosmetically acceptable medium, as thickening system: at least a non-ionic associative polyurethane and at least a non-ionic polymer comprising at least a fatty chain. A control unit controls so that a predetermined command is output multiple times to a storage device and each piece of data sent by the storage device in response to the multiple predetermined commands is received in accordance with the timing signal having a different delay amount for each of the multiple predetermined commands. To determine whether the processing device P is to be used to produce the product \u03b1 or the product \u03b2, an input ratio of each kind of product is multiplied by the number of times of passing the processing device P for each kind of product, thereby calculating a core of each kind of product.
