Sirona Successfully Completes Safety Test for Skin Lightening Compounds

Sirona Biochem Corp (TSXV:SBM, OTCQX: SRBCF) announced that it has completed the industry-standard cosmetic safety tests for TFC-849 and TFC-723, which are lightening compounds. Both tested negative on phototoxicity and skin irritation tests.

As quoted in the press release:

The phototoxic potential of TFC-849 and TFC-723 was evaluated at a concentration range 0 to 1000 µg/ml for 1 hr on fibroblast cultures, exposed to the highest non-cytotoxic UVA irradiation dose (5 J/cm²). Fibroblasts’ viability was assessed using the neutral red uptake method and compared in both irradiated and non-irradiated cultures. Neither compound (TFC-849 or TFC-723) showed phototoxicity in the concentration range tested.
