The increasing pressure of reducing the cost of production, without adversely affecting the overall performance of the products to satisfaction of the consumers are some of the propelling factors for production improvement in the industry. In this research, the influence of carboxymethyl cellulose (CMC) on the properties of liquid detergent was investigated. Chromolaena odorata Carboxymethyl cellulose-detergent (CO-CMC-Det), Penniseteum purpureum Carboxymethyl cellulose (PP-CMC-Det), Ananas comosus Carboxymethyl cellulose (AC-CMC-Det), Detergent grade-CMC-Det (Detgrade-CMC-Det) and without CMC (Water–Det) were prepared after neutralization reaction between sodium hydroxide and linear alkylbenzene sulphonic acid. The viscosity analysis of the detergents revealed that Water–Det had 2.39, CO-CMC-Det had 4.77, PP-CMC-Det had 4.84, AC-CMC-Det had 4.25, while Detgrade-CMC-Det had 5.12. All the detergents had a specific gravity of 1.03 except Water-Det which had 1.01. All the detergents fortified with CMC had better cleaning performance of over 25% while Water-Det had 17.50%. The biodegradability test using biochemical oxygen demand (BOD) as the index indicated that degradation of the detergent recorded a drop in BOD which ranged from 1.18 to 2.29 in the first month and then ranged from 0.01 to 0.04 after seven months. The research revealed that addition of CMC could affect the performance of detergent positively
