Dispersant DMA 40 by Organik Kimya is an APEO-free, low-foaming, highly effective liquid dispersant for pigments and extenders in aqueous systems. It is compatible with all common synthetic emulsions, creates little foam and is effective in a wide pH range. It is very favorable in case of storage stability of highly filled emulsion paints. Recommended dosage level is 0.1-0.3%. The maximum shelf life is 12 months at temperature 5-40°C.Low foaming polymeric dispersing agent for textile application.Dispersant DMA 40 are linear polymers with a high molecular mass (Mr ≤ 100 000) and with many carboxylate groups. They are polymers of acrylic acid or copolymers of acrylic acid and maleic acid. The polymer is used as the sodium salt (see: sodium polyacrylate).Dispersant DMA 40 are used as builders in detergents.[2] Their high chelating power, even at low concentrations, reduces deposits on the laundry and inhibits the crystal growth of calcite.Dispersant DMA 40 ethers (PCE) are used as superplasticizers in concrete production.Dispersant DMA 40 are poorly biodegradable but have a low ecotoxicity. In the sewage treatment plant, the polymer remains largely in the sludge and is separated from the wastewater.Polyamino acids like polyaspartic acid and polyglutamic acid have better biodegradability but lower chelating performance than polyacrylates. They are also less stable towards heat and alkali. Since they contain nitrogen, they contribute to eutrophication.Water-soluble linear Dispersant DMA 40 are used in household cleaning products, e.g. in laundry detergents, automatic dishwashing detergents and various hard surface-cleaning formulations, and also in institutional and industrial cleaning processes and a variety of technical applications.Dispersant DMA 40 are used in low-phosphate and phosphate-free detergents for avoiding incrustation and soil redeposition. Their effect is not based on complexing properties and therefore not comparable with typical chelating agents. The mechanism is the dispersion of calcium carbonate or calcium phosphate and the suspended solids during washing processes. Major Dispersant DMA 40 used in detergents products comprise two different types of polymer families which distinguish in their technical applications and physical chemical properties: homopolymers of acrylic acid (P-AA) which is described in part I and copolymers of acrylic/maleic acid (P-AA/MA) which is described in part II of the report.The main pathway of Dispersant DMA 40 into the environment is via domestic waste water and sewage treatment to surface waters.Thus, the removal of Dispersant DMA 40 from waste water before and during waste water treatment is the crucial factor that governs the distribution of Dispersant DMA 40 into the environment.The outcome of this current environmental assessment provides a sound basis for the conclusion that the use of Dispersant DMA 40 homopolymers in detergent products does not pose risk to the environment.Scenarios relevant to the consumer exposure to Dispersant DMA 40 have been identified and assessed using a Margin of Safety approach.Dispersant DMA 40 are of low toxicity by all exposure routes examined.Based upon the available data, it is considered that exposure to Dispersant DMA 40 does not imply any particular hazard to humans.Owing to the presence of Dispersant DMA 40 in many commonly used household detergents, consumers are exposed to Dispersant DMA 40 mainly via the dermal route, but also to a minor extent via the oral and inhalation route.In summary, based on the available data, the human risk assessment considers the use of Dispersant DMA 40 in household laundry products and automatic dishwashing detergents as safe and of no concern with regard to consumer use.Important Dispersant DMA 40 in detergents are homopolymers of acrylic acid which are generally used as sodium salts.The various Dispersant DMA 40 are distinguished by the monomers used for their preparation, acrylic acid (AA) and their molecular weight (MW).Dispersant DMA 40 used in detergents are generally prepared by free-radical polymerisation of acrylic acid in aqueous solution.Dispersant DMA 40 are very stable compounds as the carboxyl part of the molecule is the only functional group.Abiotic degradation mechanisms like photolytic and hydrolytic processes do not significantly influence the environmental fate of Dispersant DMA 40.Experimental data on the bioaccumulation potential of Dispersant DMA 40 are not available.Dispersant DMA 40 are used in low-phosphate and phosphate-free detergents for avoiding incrustation and soil redeposition.Dispersant DMA 40 are usually not contained in manual dishwashing detergents.A typical mean concentration of Dispersant DMA 40 is 0.5 % for P-AA in laundry detergents. The contact time with the Dispersant DMA 40 in the course of handwashing is, according to A.I.S.E., very short (approx. 10 min) and the percutaneous absorption of high molecular weight polymers will be very low to non existant.In the following calculations the worst case assumption has been made that 1% of the Dispersant DMA 40 are available for percutaneous absorption.Assuming a fluid film thickness of 100 µm (0.1 mm or 0.01 cm) (Vermeire, 1993) on the skin and, as a worst case assumption, a percutaneous absorption of 1% for Dispersant DMA 40 in 24 h exposure time, the following amount of Dispersant DMA 40 absorbed via skin can be calculated.Thus, the systemic exposure of Dispersant DMA 40 resulting from this scenario is also considered to be negligible.Dispersant DMA 40, despite their solubility in water, are deposited in solid form and thus as a first rough estimation, the small amount of Dispersant DMA 40 absorbed via this route should be insignificant.Accidental or intentional overexposure to Dispersant DMA 40 may occur via laundry detergents. We know no fatal cases arising from oral uptake of Dispersant DMA 40.The accidental or intentional overexposure to Dispersant DMA 40 directly is not considered a likely occurrence for consumers, but it may occur via laundry detergents.Accidental ingestion of milligrams of Dispersant DMA 40 as a consequence of accidental ingestion of laundry and cleaning products is not expected to result in any significant adverse health effects, given the low toxicity profile of laundry and cleaning products in general.Accidental contact of Dispersant DMA 40 with the eyes is not expected to cause more than a slight irritation on the basis of the experimental data.Data on developmental toxicity demonstrate that Dispersant DMA 40 are not developmentally toxic in rats.In summary, based on the available data, the human risk assessment considers the use of Dispersant DMA 40 in household laundry products and automatic dishwashing detergents as safe and of no concern with regard to consumer use.
