Abstract: Detergent can be defined as substance which improves the cleaning power of water by lowering its tension. The objective of this research work is to determine the effect of colorant on the quality and marketability of liquid detergent. In order to achieve this objective, the various constituent in required quantities were compounded to formulate a cleansing agent used in removal of dirt. Long chain organic acid was made to neutralise caustic soda and additives were added to the mixture obtained (at pH 6.8 to 7.2) to give required colours (pink, blue, green, glow green and yellow): formalin / methanol to prevent acidity as a germicidal and anti-bacterial agent and perfume, (rose, jasmine etc) to give the desired smell. The quality of various sample were tested and their marketability evaluated with questionnaire by the consumers. The result obtained showed that colorant does not have any negative effect on the quality of the liquid detergent produced. However it was observed from data obtained from the consumers, that yellow coloured liquid detergent was most preferred. It is recommended that more of yellow coloured liquid detergent should be produced for sales by the producer to enhance profitability.
