Evaluation of cosmetic lipsticks for hazardous heavy metals and determination of antimicrobial potency

Background: Lipstick, a cosmetic product containing pigment, wax materials, oils and emollient that apply color, is the most widely used make-up to enhance beauty of lips. Consciously or unconsciously, lipsticks have cast spell over cultures for years its possible health implications on consistent wearer's remain subject controversy. This study evaluated commercial purchased from selected beauticians' shops in Ibadan antimicrobial potency hazardous heavymetals. Methods: One gram (1g) representative samples was weighed analytical weighing balance dissolve 10 mL acetone. A stock concentration 100mg/mL prepared using 50% acetone as diluents. Thereafter, 5mL pipette 5mls 5% make 50mg/mL . quantity 0.8g each were 8mL HNO3: HCl (1:3) added beaker. The heated preparation allowed cool filtered removed undissolved waxy while digested solutions made up mark 40 ml with sterile distilled water. sample analyzed Cr, Pb, Cd, Mn, Fe Zn FlameAtomicAbsorption Spectrophotometer. Culture E. coli, S. aureus, K. pneumonia, Streptococcus sp, Pseudomonas aeruginosa seeded moltenMueller Hinton agar challenged (100mg/mL 50mg/mL) concentrations dissolved well diffusion technique. Results: Lead found varied all 15 examined, Cadmium, Magnesium, Zinc Iron 7 samples, Chromium 3 total examined. Thirteen (13) examined exhibited property against Escherichia Staphylococcus aureus Klebsiella spp at either 100 mg/mLand/or 50mg/mL. Conclusion: degree heavy metals detected could be inimical user's coupled susceptibility some bacteria clinical potential. There therefore need extensive testing assess assure efficacy regularly before delivery markets.
