Abstract
A non-intrusive device for automatically dosing at least one liquid laundry care composition to an automatic laundry washing machine. The device employs a Venturi tube mechanism or a pump to dose the laundry detergent care composition. The dosing is controlled by a machine-generic algorithm capable of determining the actual cycle at any duration of wash for various cycle designs from various washing machines, without the input of precise cycle design; and dose the correct products correctly and is capable of distinguishing between major water addition and a water pulse.
