Sodium lauryl sulphate (SLS) and Saccharin (SHN) levels in 10 different toothpaste brands were determined spectrophotometrically. The result obtained showed significant difference in SLS and SHN concentrations in the sampled toothpastes. The concentration of the SLS sampled toothpastes ranged from 1.56104 10.11 mg/Kg to 2.13104 10.22mg/Kg while that of the SHN ranged from 833104 17.29 mg/Kg to 2.32105 11.47mg/Kg. The result obtained from the analysis of SLS in the toothpaste samples shows that T2 also had the highest concentration of 2.13104 10.22 mg/Kg while T8 had the lowest concentration of 1.56104 10.11 mg/Kg.The concentration of SHN in the toothpastes are unacceptable when compare to the daily acceptable intake (ADI) established by regulatory agencies. This implies that these toothpastes could be a potential poison to consumers especially the vulnerable children that have the tendency for uncontrollable intake.
