About Soil2O DUST CONTROL
Soil2O DUST CONTROL is a sodium polyacrylate material that is used extensively in the agricultural industry and is infused in the soil of many potted plants to help them retain moisture, behaving as a type of water reservoir. Florists commonly use sodium polyacrylate to help keep flowers fresh, and this substance has been approved for domestic fruit and vegetable growing by the U.S. Department of Agriculture. Sodium polyacrylate is a polymer, meaning that it consists of chains of identical units (monomers). The monomer for sodium polyacrylate is:--CH2--CH(CO2Na)—
Unlike Polyvinyl Acetate which is:
Polyvinyl acetate, PVA, PVAc, poly(ethenyl ethanoate), is a rubbery synthetic polymer with the formula (C4H6O2)n. It belongs to the polyvinyl esters family with the general formula -[RCOOCHCH2]-. It is a type of thermoplastic.
Superabsorbent polymers are used primarily as intermediate and raw materials in a variety of consumer and industrial products including treatment of municipal waste water. The testing and approval process includes the, the Occupational Safety and Health Agency (OSHA), US Food and Drug Administration (FDA), United States Department of Agriculture (USDA), Mine Safety and Health Administration (MSHA) as well as recognized third party laboratories and testing facilities. The product has been tested as a food additive and carries approvals to be in contact with food for human consumption. Although best practices should be maintained when working with all products the product poses no exposure risks as defined by the FDA.
The following are complete government verified data sets showing the results of the provided health and environmental information:
Acute oral toxicity
Up to 5 % mixed solution applied as gel in saline was applied once with a stomach tube to 5 male and 5 female rats each. No abnormal findings were evident at any time point during examinations over 14 days. Bodyweight development was normal; necropsy revealed no visible organ alterations. The LD50 was> 5,000 mg/kg body weight. Application of an aqueous extract of the SAP to 6 male and 6 female rats with the drinking water for 1 day led to no adverse effects. Deaths did not occur and no visible organ changes were detected. Neither the polymer nor the mixed solution is of acute toxicity after oral administration.
Subacute oral toxicity
The oral toxicity of mixed gel, administered daily to 10 male and 10 female rats per group via the diet over consecutive weeks at concentrations of up to 5 % was investigated. No toxicologically significant changes were induced. The differences observed between treated and control animals were modifications in urinary ion excretion in the treated animals. Both findings were considered to be related to the relatively high concentration of sodium in the test substance and therefore of no toxicological relevance.
The hen's egg test is an alternative test method to the Draize rabbit eye test. For this test 200 mg of dry product, the swollen gel or an extract were applied onto the sensitive chorioallantoic membrane (CAM) of the developing chicken egg. There were only slight irritative effects leading to vascular injection but no adverse effects with respect to hemorrhaging, or coagulation. Thus the potential of the product to cause adverse effects on membranes seems to be very low.
Cytotoxicity in vitro
The product was examined regarding its influence on mammalian cells in a cell culture system using 3T3 fibroblasts of mice. The cells were incubated for 24 hours with an extract of the product in concentrations up to 1.5 % (v/v) in cell culture medium. No adverse effects on the morphology or viability of the cells were observed. Extraction of product with cell culture medium (10 g/medium) led to a concentration dependent decrease in cell viability due to complex formation (binding) of essential cations in the medium. Following supplementation of the bound cations, adverse effects were not observed any longer. Further cell toxicity tests were executed using the agar diffusion cell culture technique, which is appropriate for solid specimens as well. The product was applied as dry granulate and as a suspension (30 g/l saline). There was no indication of cytotoxic effects.
Intravenous and intra peritoneal application
Intravenous and intra peritoneal compatibility of SAP was tested after systemic injection in mice. Following intra peritoneal application of 50 ml/kg extract in sesame oil or 10 g/kg extract in polyethylene glycol no toxic reactions of the animals were observed within 72 hours.
Intravenous instillation of a gel extract (15 g/l saline) produced systemic effects and mortality in dose levels greater than40 ml/kg. Histopathological examination revealed dose dependent toxic alterations of liver and spleen. The no observed effect level (NOEL) was less than 10 ml/kg, a dose which led only to minimal hepatic effects.
Subcutaneous and intramuscular implantation
Subcutaneous and intramuscular compatibility of a gel and the granulate of product was tested in rabbits after implantation. Histopathology revealed no abnormal reactions in the surrounding tissue. Furthermore, there were no significant deviations from normal values in hematology, clinical chemistry, and other standard toxicological parameters. No signs of toxicity were observed.
Escherichia coli reverse mutation assay
Extracts of the product were tested in tryptophan requiring strains of Escherichia coli for their ability to induce point mutations in the absence or presence of a metabolic activation system. In concentrations of up to 5,000 μg/plate no mutagenic events could be observed. Furthermore, no cytotoxicity was detected.
UDS in rat hepatocytes in vitro
The product was tested for its ability to induce unscheduled DNA synthesis (UDS) in isolated rat hepatocytes in vitro. Treatment with up to 1,500 μg/ml of equivalent extracted material in saline with 10 % (v/v) ethanol did not produce a mean net grain count greater than zero (0), nor were 20 % or more cells to be found in repair. The test substance therefore showed no genotoxic activity.
Pregnant female rats were exposed in a teratology study to respirable levels (particle size< 10 μm) of product at 0.3, 1.0and 10 mg/m³ for 6 hours/day from day 6 to day 15 of gestation. On day 20 of gestation the rats were necropsied and examined for the number of implantations, early and late resorptions, live and dead fetuses and number of corporalutea. The fetuses were observed for weight, external, soft tissue and skeletal alterations. No effects were detected: The highest test concentration is the no observed effect level (NOEL).
