Abstract (en)
[origin: EP0255978A2] An acidic, aqueous liquid detergent composition, especially suitable for toilet bowl cleaning, is provided with a colour-change ingredient to enable the user to monitor the concentration of the composition upon dilution with water when using the product. By including a detergent-active compound which exists in cationic form in the acid composition and a dye which undergoes a pH-dependent colour change in the acid pH range, the required colour change indication is obtained.
