Dear Sir. Concerning your issue about the life cycle inventory data for "Propyl gallate". Propyl gallate, propyl ester of gallic acid, n-propyl ester of 3,4,5- trihydroxybenzoic acid, propyl 3,4,5-trihydroxybenzoate. The inventory analysis of the LCA comprises the data collection and the calculation procedures to quantify the inputs and outputs (energy, raw materials, air, water, soil, etc.) through the system boundaries. To make the analysis easier, the system is divided in several interconnected subsystems. Propyl gallate is considered to be moderately toxic to aquatic organisms. Ecological concerns for listed and nonlisted species are not likely from the use of propyl gallate as an inert ingredient in pesticide products. According to the 1985 CIR report, of rats fed diets containing 0 to 5% propyl gallate for two years, patchy hyperplasia of the stomach was observed at the 5% dosage. The environmental fate of propyl gallate will limit its likelihood of reaching either surface (drinking water) or ground water or bioaccumulating in the environment. Propyl gallate is expected to biodegrade in the environment with ultimate aerobic degradation estimated to be weeks and primary degradation in days. Propyl gallate is soluble, nonvolatile, and moderately mobile. Leaching to ground water is likely in sandy or porous soils, however, mitigated in other soils due to biodegradation. While atmospheric degradation is expected to be rapid, the potential to volatilize from surface waters is very low. I think the following below links may help you in your analysis:
