Risk assessment of manganese in lip cosmetics

ObjectiveTo determine the level of manganese and assess potential health risks of lip cosmetics.

MethodsAssessment on manganese of lip cosmetics was performed using high-end exposure analysis mode based on the daily dosage.

ResultsIn a total of 264 lip cosmetics samples， manganese was detected in the 249 sample， with a detection rate of 94.3%. Daily exposure was determined to be 3.88×10^-5 mg/kg. Safety margin was 3 608 and safety limit was 45 mg/kg.

ConclusionLevel of manganese in lip cosmetics remains safe. Health risk is low when appropriately used according to the daily usage. However， it is noted that level of manganese exceeds the limits in approximately 10% of the samples， posing a potential health threat.
