A Belfast business owner has pleaded guilty to charges related to the use and supply of "carcinogenic" tooth whitening products.
Samuel Irvine Madine, owner of the HD Smile Clinic on the Shankill Road, pleaded guilty to five charges at Belfast Magistrates Court after a case was brought by Belfast City Council.
Mr Madine was found to have breached Comestic Product Enforcement Regulations.
Officers from the council’s Environmental Health department carried out a number of inspections of the business premises following a complaint received in April 2015.
Four different products were seized over a period of time for testing. The seized products were found to contain sodium perborate, a banned substance which is carcinogenic.
Testing of the products revealed that all samples contained levels of hydrogen peroxide in excess of the permitted level of 0.1%, with one product being more than 300 times greater than this.
Mr Madine also pleaded guilty to failing to meet the obligations of a distributor, including the required safety and labelling requirements.
Professor Angus Walls, director of the Dental Institute in Edinburgh, advised that “the risks of chemical burns and malignant change are much greater with increased percentage of hydrogen peroxide”.
The case has been adjourned until 4 June for sentencing.
