The sedative test provided by BALLYA PlaFast Test can detect many plasticizers. Include 3 types of detection methods: Colloidal gold immunochromatography, Immunofluorescence chromatography and ELISA. There are quantitative and qualitative format rapid test, easy to operate, shortern assay time, reliable detection result. The test is done using competitive ELISA (competitive ELISA). Competitive ELISA is a very sensitive detection method that uses antibodies prepared against plasticizers. The BALLYA PlaFast Test frequently use in feeds, foods and Chinese herbal medicine, etc.
Plasticizers mainly include aliphatic dibasic acid esters, phthalic acid esters (including phthalic acid esters, terephthalic acid esters), benzene polyacid esters, parabens, and polyol esters, Chlorinated hydrocarbons, epoxy, citrate, polyester, etc.
Why need BALLYA PlaFast Test?
What is a plasticizer?
Plasticizer is a polymer material additive widely used in industrial production, also known as plasticizer. The substances that are added to the polymer material to increase the plasticity of the polymer are called plasticizers.
The use of plasticizers can improve the performance of polymer materials, reduce production costs, and increase production efficiency. It is an important class of chemical product additives.
The main performance of plasticizer
Plasticizers are usually polar or partly polar in structure, and are liquids or low-melting solids with high boiling point, low volatility and good miscibility with polymers.
The plasticizer is distributed between the macromolecular chains, which can reduce the intermolecular force, reduce the viscosity of the polymer and increase the flexibility. Plasticizers are divided into two categories: primary and secondary plasticizers. The role of the primary plasticizer is to have a good compatibility with the resin, with low permeability and low volatility, which can improve plasticization efficiency.
Commonly used main plasticizers are phthalate esters and phosphate esters. The auxiliary plasticizer is also called auxiliary plasticizer. Its main function is to use with the main plasticizer to reduce costs. Commonly used auxiliary plasticizers include aliphatic dibasic acid esters and other cold-resistant types and cyclic ester plasticizers Agent.
Different types of plasticizers have different effects on the performance of products. In actual production, one plasticizer is rarely used alone, and several plasticizers are often mixed with complementary properties to achieve a good plasticizing effect.
What does a plasticizer do?
Concrete application Plasticizers can reduce the water content of concrete without affecting the workability of concrete (hence the name water reducer), and at the same time increase the strength of concrete. This method is often used to increase the strength when producing high-strength concrete or fiber reinforced concrete.
Gypsum drywall application The plasticizer used in gypsum drywall is also called dispersant, which can increase the processability of gypsum before it sets.
Energetic material application Energetic materials and pyrotechnics generally use plasticizers. On the one hand, they can improve the physical properties of the propellant itself or its binder. On the other hand, it can also be used as an auxiliary fuel to increase the propulsion provided by the unit mass of fuel.
Food packaging Polylactic acid (PLA) has its own unique advantages when used as food packaging materials. It can completely replace traditional packaging materials, and its unique environmental protection makes it an important place in the future development of packaging materials.
Plasticizers in food
Unlawful addition In order to pursue the attractive appearance of the products, some illegal businesses, such as the viscosity of beverages and the hanging of alcohol, illegally add plasticizers to foods to reduce production costs and at the same time achieve high-quality appearance requirements.
Serious environmental pollution There are more and more applications of products that use plasticizers in processing, which have an impact on the environment, such as the volatilization of plasticizers in agricultural films in farmland and the use of insect repellents; in addition, the processing after use is relatively simple. All make plasticizers the most widespread environmental pollutants.
The raw materials of various processed foods absorb plasticizers from the polluted environment and enter the finished products as they are processed.
Processing link Various types of food processing will inevitably come into contact with some equipment or pipes and containers made of plastic and rubber materials. If they contain plasticizers, they may migrate into the product and contaminate the product.
The impact of plastic packaging materials Many utensils in food packaging and production processes may be plastic products, and a large part of them may be polyvinyl chloride (PVC) with relatively large plasticizer components.
Toxicity of plasticizers
PAEs can enter the human body through the respiratory tract, digestive tract and skin, and the pollution of PAEs in the population has been quite serious.
Carcinogenic, teratogenic and mutagenic effects PAEs can act on the chromosomes of cells, causing changes in the number or structure of chromosomes, causing some tissues and cells to grow out of control and cause tumors.
Influence on male reproductive tract development PAEs show obvious anti-androgen effects in vivo and in vitro experiments and animal models, and have an impact on the development of the endocrine and reproductive systems of infants and young children.
Toxic effect on female reproduction The estrogenic effects of PAEs may be related to the abnormal development of the reproductive system, reproductive dysfunction, tumors of the reproductive system and endocrine system, as well as the development and functional damage to the nervous system.
Plasticizer poisoning
There are reports of acute poisoning caused by accidental ingestion of PAEs, which can cause gastrointestinal irritation, central nervous system depression, paralysis, and lower blood pressure.
The chronic toxicity of PAEs is mainly manifested by decreased renal function, increased number of focal renal cysts and renal tubular pigmentation. In addition, PAEs can also cause liver toxicity, lung toxicity, and cardiotoxicity. Long-term exposure to PAEs can cause symptoms such as polyneuritis, hypoesthesia, and numbness.
Note: Use plasticizer carefully, listen to expert guidance, and do not use them indiscriminately.
There are more and more applications of products using plasticizers in processing, which have an impact on the environment during use, such as the volatilization of plasticizers in agricultural films in farmland and the use of insect repellents.
In addition, the treatment after use is relatively simple, that is, the incineration of plastic products, and the transfer of the products after incineration to the air and soil, all of which make plasticizers the most widespread environmental pollutant. In many countries, the Different concentrations of plasticizer were detected.
The raw materials of various processed foods absorb plasticizers from the contaminated environment and enter the finished products as they are processed. Oil crops such as soybeans and rapeseeds are brought in to dissolve the plasticizers in the oil.
The detection of plasticizers in food has become an important part of ensuring food safety.
Conclusion
Plasticizers are widely present in every corner of life. According to modern lifestyles, it is almost impossible to avoid plasticizers completely, but there is no need to be overly nervous, because plasticizers in normal life will not harm the human body. However, people should contact plastic products containing plasticizers as little as possible.
The BALLYA PlaFast Test provided by BALLYA can effectively detect plasticizers residues in grain, food, tobacco and Chinese herbal medicine. Its simple operation, short detection time and high accuracy are major features of this product.
