Sirona Biochem Corp. (TSX VENTURE:SBM) announced today its subsidiary, TFChem, demonstrated stability of its skin depigmenting agents for cosmetic skin lightening. The company's compounds, TFC-849 and TFC-723, were more stable than alpha- and beta-arbutin, two of the world's most popular skin lightening compounds. In addition, the company's compounds did not release hydroquinone, a potentially toxic substance linked to many leading skin lighteners. The study, funded through a $1.9 million French grant, is led by TFChem and involves a consortium of partners.

"We are addressing a major concern of skin lighteners by developing an alternative that does not release hydroquinone," said Neil Belenkie, Chief Executive Officer of Sirona Biochem. "This study proves that we are on track to producing an effective and safe skin depigmenting agent that major cosmetic brands are seeking in their formulations," he added.

Stability of the company's compounds, TFC-849 and TFC-723, was measured in multiple conditions: chemical (buffer, pH, temperature), enzymatic (alpha- and beta-glucosidase, enzymes causing degradation of natural arbutins), and biological (sweat and skin tissular or cellular extracts). For comparison, alpha- and beta-arbutin were also tested in the same conditions. In all tested conditions, Sirona Biochem's compounds were stable and did not release hydroquinone. However, the study showed both alpha- and beta-arbutin released hydroquinone.

Further studies to evaluate the company's compounds' safety and microbial innocuity are ongoing.

In Asia and the United States, hydroquinone is a commonly used but potentially toxic skin lightening agent. In some cases, commercial formulations of skin lighteners break down causing the release of hydroquinone. Safety concerns and adverse events related to the use of hydroquinone have resulted in the European Union banning its use and the United States putting restrictions on allowable hydroquinone concentration levels.
