Clove bud absolute was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, photoirritation/photoallergenicity, skin sensitization, and environmental safety. Data for components of the NCS do not show a concern for genotoxicity. Clove bud absolute was evaluated for the repeated dose and reproductive toxicity endpoints on the basis of component analysis using a combination of target data, read-across data, and Threshold of Toxicological Concern (TTC); clove bud absolute is safe for use under the conditions described in this safety assessment for the repeated dose and reproductive toxicity endpoints. Data for components of the NCS do not show a concern for skin sensitization under the current declared levels of use. The photoirritation endpoint was evaluated based on ultraviolet/visible (UV/Vis) absorption spectra for the components of the NCS; clove bud absolute is not expected to be photoirritating. The photoallergenicity endpoint was evaluated based on UV/Vis absorption spectra for the components of the NCS; clove bud absolute is not expected to be photoallergenic. The local respiratory toxicity endpoint for this NCS was evaluated using the inhalation TTC for a Cramer Class III material, and the inhalation exposure to clove bud absolute is below the TTC (0.47 mg/day). Based on the component assessment, clove bud absolute does not contain Persistent, Bioaccumulative, and Toxic (PBT) or (very) Persistent, (very) Bioaccumulative (vPvB) components as per the IFRA Environmental Standards and does not present a risk to the aquatic environment at the current reported VoU.

Sorbitol (SOR) is a natural food sweetener that is widely used in candies, chocolates, biscuits, and jams. SOR showed toxic impacts on different body organs except renal tissues. Therefore, the present investigation was conducted to assess the sub-chronic nephrotoxic effects of SOR on renal tissue. Thirty-six Sprague Dawley rats were apportioned into control, SOR (20 mg/kg), SOR (45 mg/kg) and SOR (90 mg/kg) treated group. SOR intoxication showed upregulation in the gene expression of JAK1, STAT3, NF-κB, TNF-α, IL-18, IL-6, IL-1β, and COX-2. The levels of ROS and MDA were promoted while the enzymatic activities of HO-1, SOD, GPx, GSR, CAT and GST were reduced after SOR administration. SOR exposure showed elevation in the levels of cystatin C, BUN, KIM-1, urea, creatinine, uric acid, NAG, while a reduction in creatinine clearance in dose-dependent manners. Besides, SOR intoxication escalated the levels of Caspase-9, Caspase-3 and Bax while reducing the levels of Bcl-2. Moreover, SOR administration distorted the renal histology at all the tested doses. These findings suggest the nephrotoxic effects of SOR in dose-dependent manners as 90 mg/kg > 45 mg/kg > 20 mg/kg owing to its pro-oxidative, pro-inflammatory and pro-apoptotic attributes.

Nonyl alcohol was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, photoirritation/photoallergenicity, skin sensitization, and environmental safety. Data from read-across analog heptyl alcohol (CAS # 111-70-6) show that nonyl alcohol is not expected to be genotoxic and provide a calculated Margin of Exposure (MOE) >100 for the repeated dose toxicity and reproductive toxicity endpoints. Data from read-across analog 1-decanol (CAS # 112-30-1) provided nonyl alcohol a No Expected Sensitization Induction Level (NESIL) of 10000 μg/cm2 for the skin sensitization endpoint. The photoirritation/photoallergenicity endpoints were evaluated based on ultraviolet/visible (UV/Vis) spectra; nonyl alcohol is not expected to be photoirritating/photoallergenic. The local respiratory toxicity endpoint was evaluated using the Threshold of Toxicological Concern (TTC) for a Cramer Class I material, and the exposure to nonyl alcohol is below the TTC (1.4 mg/day). The environmental endpoints were evaluated; nonyl alcohol was found not to be Persistent, Bioaccumulative, and Toxic (PBT) as per the International Fragrance Association (IFRA) Environmental Standards, and its risk quotients, based on its current volume of use (VoU) in Europe and North America (i.e., Predicted Environmental Concentration/Predicted No Effect Concentration [PEC/PNEC]), are <1.

The health implications of genetically modified (GM) crops remain controversial relative to their non-GM counterparts, particularly regarding long-term dietary exposure. Although the gut microbiome is a key health indicator, studies investigating the impact of GM crop consumption on intestinal microbiota remain limited. This study presents a comprehensive 7-year evaluation of GM maize expressing cry1Ab/cry2Aj and G10evo-EPSPS proteins through metagenomic and metabolomic analyses. We assessed the effects of GM maize consumption on gut microbiota diversity and metabolite profiles in cynomolgus macaques (Macaca fascicularis) compared with non-GM maize. Three diet regimens were implemented: a conventional compound feed (CK group), diet formulation containing 70 % non-GM maize (Corn group), and diet formulation containing 70 % GM maize (Tg group). The results demonstrated that feeding GM maize to the first (F0) and second (F1) generations of monkeys did not substantially affect the composition, community structure, or function of the intestinal microbiome, as indicated by species composition and diversity analyses. Minor differences in intestinal metabolites were observed but were not directly linked to transgenic maize consumption. Collectively, long-term intake of maize with cry1Ab/cry2Aj and g10evo-epsps genes had no adverse effects on macaques or their offspring.
