Assessing the genotoxicity and carcinogenicity of 2-chloroethanol through structure activity relationships and in vitro testing approaches.

The detection of 2-chloroethanol in foods generally follows an assumption that the pesticide ethylene oxide has been used at some stage in the supply chain. In this situation the Pesticide Residues in Food Regulation (EC) 396/2005 requires 2-chloroethanol to be assessed as if equivalent to ethylene oxide, which has been classified as a genotoxic carcinogen. This review investigated whether this is an appropriate risk assessment approach for 2-chloroethanol.

Threshold of toxicological concern (TTC) for botanicals - Concentration data analysis of potentially genotoxic constituents to substantiate and extend the TTC approach to botanicals.

This paper evaluates use of the Threshold of Toxicological Concern (TTC) approach to assess safety of botanical preparations that may contain potentially genotoxic constituents, based on estimation of the fraction that may be genotoxic. A database of 107 chemical constituents of botanicals was compiled and their potential for genotoxicity evaluated from published data. Forty-three constituents met the criteria for potential genotoxicity.

Safety evaluation of superabsorbent baby diapers.

Superabsorbent disposable baby diapers are sophisticated, well-engineered products that provide many benefits including convenience, comfort, exceptional leakage protection, improved hygiene and skin care benefits compared with cloth diapers. Safety assurance is an integral part of the diaper development process at Procter & Gamble, with the goal of ensuring safety for both caregivers and babies. A systematic, stepwise approach to safety assessment starts with a thorough evaluation of new design features and materials, using the principles of general risk assessment including, as appropriate, controlled trials to assess clinical endpoints or independent scientific review of safety data.
