The UV Absorber UV-328 is a chemical that is used as an ultraviolet absorber in several products. Its main applications are in the automotive industry and the defense industry, where it prevents the color and material degradation caused by UV light. This chemical is also used in printing inks, outdoor furniture, construction materials, and food packaging. It can also be found in leather, textiles, and cosmetics. Read on to learn more about UV-328 and its different applications.
The chemical substance UV-328 is made up of a phenolic benzotriazole with tert-pentyl groups at the fourth and sixth positions. Because of this, it absorbs all wavelengths of Light Stabilizer UV-360 . UV-328 has a high affinity to absorb light, making it useful as an UV absorber. It protects surfaces from discoloration and weathering, and can be produced in both closed and open forms.
Alternatives to UV-328 have been developed. Alternative substances are available to replace UV-328, and some of them are already supplied by registrants in the EU. However, these alternatives haven’t been quantified yet. The co-registrants of UV-328 are confident that downstream users will switch to safer alternatives as soon as possible. There’s no reason why the replacement of UV-328 is impossible. However, this substitution will come with transition costs.
In terms of production, UV-328 is produced in significant quantities in the world. Global production is around 1,000 tons per year, but there are no time trends. The usage volume in Japan and Belarus is much smaller than this. The number of companies using UV-328 is below 1,000 t/a. Further, UV-328 is not widely used in Europe. But it’s growing in popularity in the US and elsewhere. So, what’s the future of UV-328?
While it’s not yet clear whether UV-328 has a negative impact on marine life, it is already being used in plastic products. Its presence in plastic waste is a major problem, as this substance is present in specific plastic waste streams. This means that it’s necessary to separate UV-328-containing parts from the fraction intended for recycling. Currently, there are no established separation techniques for UV-328. The use of this chemical in plastic manufacturing is a good solution for reducing the level of plastic pollution, but further research is needed to determine its toxicity.
In addition to the use of UV-328 in the automotive industry, UV-328 is commonly found in vehicles’ exterior parts. More than 99% of UV-328 is found in radiator grills. As vehicles replace parts, the UV-328 phaseout will be inevitable. This chemical may be removed from new vehicles in 2026. This will not be feasible, however, for vehicles that have been manufactured and are currently in stock.
The UV-328 in textiles is persistent and bioaccumulative, which makes it a particularly bad choice. It has significant adverse environmental and human health effects. The ban of UV-328 would reduce the amount of pollution and deaths caused by hazardous chemicals. It would also align with the Strategic Approach to International Chemical Management. Its ban would be an important step towards protecting the environment and human health. The UV-328 in textiles can be found in many fabrics and in many different types of paints.
