Sodium carboxymethylcellulose in detergent products reacts with phenol in a sulfuric acid media to give a colored reaction product, the absorbance of which is measured at 490 mµ. No interference was experienced from the normal constituents of detergent products. The reproducibility was found to be±0.05% absolute.
