Abstract
Hydroquinone, Retinoic acid and Mercury compounds are restricted for their use in acne-melasmacosmetics, according to Ministry of Public Health Regulation announcement, B.E. 2551. However their presencein such products have still been detected. In the year 2006, Regional Medical Science Center, Songkhla surveyedthe marketed products in Songkhla Province and its border area, for the presence of the aforementioned substances.Identi\ fication of these chemicals was done by thin-layer chromatographic technique and chemical reactions test.Sixty-six percent of samples found these restricted substances. All contaminated are registered for labelingproducts. In 2007, investigation at cosmetic products collected in Songkhla Province and its neighboring area (Satoon,Pattani, Yala and Narathiwat) revealed the presence of these substances in forty-eight percent of the testedcompound. This information indicate the high proportion of unsafe products. The incidence likely increasesrisk for users to the toxic effects originated from these substances. For the safety of cosmetics users, strictlaw enforcement is therefore necessary to limit the violated use of these substances in the acne-melasmacosmetics.Key words : Hydroquinone, Retinoic acid, Mercury and its compounds, Acne-Melasma Cosmeti
