Quantitative determination of benzyl benzoate in benzyl benzoate lotion NF

The development of a simple, shorter and more accurate method than the NF method for the determination of benzyl benzoate in Benzyl Benzoate Lotion NF is discussed. Hydrolyzed benzyl benzoate was measured spectrophotometrically. Interference from other ingredients of the lotion, oleic acid and triethanolamine was almost negligible. The proposed method was completed in approximately 15 minutes, as opposed to the two hours required by the NF procedure.
