core tip: on June 9, 2017, the European chemical Administration (ECHA) announced that it had officially proposed to include titanium dioxide (TiO2, titanium dioxide) in the classification of substances suspected to cause cancer by inhalation, The opinion will be announced later through written procedures or formally adopted at the European Commission meeting in September

[China Packaging News] on June 9, 2017, the European chemical Administration (ECHA) announced that it had officially proposed to include titanium dioxide (TiO2, titanium dioxide) in the classification of substances suspected to cause cancer by inhalation. This opinion will be announced later through a written procedure or formally adopted at the European Commission meeting in September

according to the risk assessment committee (RAC) of ECHA, the existing scientific evidence shows that the carcinogenic potential of titanium dioxide meets the relevant standards under the "classification, labeling and packaging regulations" (CLP) of ECHA. However, RAC also pointed out that the conclusion showed that there was not enough evidence to support the previous French proposal to classify titanium dioxide into a more serious carcinogen category (category 1b), which was only "presumed to be a substance potentially causing cancer" (Category 2, through inhalation)

France submitted a proposal on coordinated classification and labelling (CLH) in May 2016, which requires that titanium dioxide be defined as a "substance with potential carcinogenicity to human body when inhaled" from the perspective of classification and labelling, and that it be classified as category 1b and h350i in the "CARC carcinogenic category (carcinogenicity, inhalation)". The classification is applicable to the fine particles and nano states of titanium dioxide, in terms of morphology There is no distinction between crystalline phase and surface treatment

after widely soliciting the opinions of A. high precision American force transmission pneumatic sensor: 10 ⑵ 000kg on the French proposal, RAC discussed this proposal for the first time at its meeting in March 2017

within the EU, RAC is responsible for providing independent scientific opinions on the hazard classification of substances. The classification is based only on the hazardous nature of the substance and does not consider the possibility of exposure to the substance

once implemented, it will have a huge impact

according to the latest market research and analysis, due to the increasing demand in the fields of papermaking, paint and coating, cosmetics and plastics, it is expected that by 2024, the global titanium dioxide market 4. Opening the upper cover of the experimental gearbox will reach us $27.99 billion

in 2016, the consumption of paint and coating industry accounted for 57.4% of the sales revenue of the global titanium dioxide industry. In addition, titanium dioxide products are also widely used in plastics, papermaking, printing ink and other professional fields. The growth of these industries is expected to actively promote the development of the global titanium dioxide Market in the next few years

the paper industry is the third largest user of titanium dioxide industry, with a contribution rate of 10.4% in global sales revenue

as titanium dioxide is widely used, once it is included in the scope of CLP regulation by the European Union, it will have a great impact on this industry

statement of the Titanium Dioxide Manufacturers Association (TDMA)

the European chemical risk assessment committee (RAC) recommends that titanium dioxide be classified as a suspected carcinogen (Category 2). This recommendation from France is based on the results of inhalation exposure studies on rats, although there is a large amount of scientific evidence that does not support the fact that human exposure to titanium dioxide is harmful, In particular, the epidemiological data of more than 24000 staff over the past 50 years show that there is no connection between human cancer and exposure to titanium dioxide

in the research considered by Rac, the observed results are specific and not observed in the scientific research of any other species related to it (including humans), which is only a mode of action in rats. Moreover, the result obtained in the rat experiment is only by observing the inhalation of large doses of titanium dioxide dust, whose level is many times higher than the exposure level encountered by ordinary workers. Most importantly, the relevant experimental results are actually the same for all insoluble dust substances, not just titanium dioxide, which means that many other insoluble particulate substances will also be classified as potential carcinogens

tdma chairman Robert Byrd expressed disappointment at the opinion of ECHA's RAC Committee, "the scientific evidence clearly shows that there is no reason to include titanium dioxide in the classification of potentially carcinogenic substances for humans through inhalation. In addition, this classification has no value in improving human health and environmental protection, and it is only used for labeling and classification"

tdma will transmit any scientific opinions and opinions received to the European Commission for their evaluation and decision on relevant regulatory measures. "We believe that European regulators will confirm that it is safe to continue to use titanium dioxide in all applications"

the previous scientific evaluation results of TDMA have been reflected in the archives of reach and further supported in the comments submitted by the public consultation, that is, it is not recommended to classify them

bcf and cepe issued a statement on the decision of ECHA

the British paint Federation (BCF) and cepe (European paint, ink and Art Pigment Industry Association) have noted that the risk assessment committee of the European chemical Administration (ECHA) has concluded that titanium dioxide should be classified as a "substance suspected of causing cancer by inhalation" according to the EU CLP regulations (classification, labeling and packaging). We acknowledge that this opinion is the first step in the long-term regulatory process, and hope to assure consumers and professional users that once titanium dioxide enters paint, coating, printing ink or wallpaper, there will be no exposure of solid particles with inhalation risk

the paint, coating, printing ink and wallpaper industry always takes health, safety and environment as the highest priority to ensure that the products of relevant industries meet the highest health and safety standards

titanium dioxide is an inert inorganic compound used as white pigment in many industrial fields. These applications include the production of paint, coating, printing ink and wallpaper, and titanium dioxide plays a key role in providing necessary product performance, such as whiteness, coverage, gloss, brightness, stability and durability, which cannot be achieved by other pigment raw materials, In addition, titanium dioxide is also used in the production of many other consumer goods

titanium dioxide is the powder form of titanium dioxide. The finished product obtained after its application and processing has no risk to consumers, because once embedded in the finished product, consumers and professionals using paint, coating, printing ink or wallpaper products will not be exposed to the titanium dioxide environment in the form of powder

although the production process of these products may produce an environment exposed to titanium dioxide powder, there are relevant regulations on dust prevention and worker protection at both the EU level and the national level. Moreover, studies over the years have not found any correlation between workers exposed to titanium dioxide and the risk of lung cancer. In addition, the rat test cited by ECHA uses unrealistic high-dose titanium dioxide, which is not allowed in the general production environment. Based on this, BCF and cepe believe that in the production of paint, coating, printing ink and wallpaper products, the rapid development of titanium dioxide gas turbine technology and its combined cycle is safe for workers. BCF and cepe member enterprises are constantly committed to taking all preventive measures to ensure that the safety of products and workers in their supply chain is further supported

bcf has previously put forward the above opinions to the relevant departments on the CLH proposal proposed by France and believes that according to the current labeling rules, this will lead to unexpected consequences. Even if titanium dioxide is no longer a product in the form of powder, it must be marked and listed in the "first batch utilization demonstration and guidance catalogue of key new materials" of the Ministry of industry and information technology as "it is suspected to cause cancer by inhaling powder". Due to the lack of any evidence from users, consumers or professionals of coatings and other products using titanium dioxide related to the risks involved in the proposal, the industry (especially BCF and cepe) questioned the legislation of this specific element

statement of the American paint Association (ACA) on the advisory opinion on ECHA titanium dioxide

on June 12, the American paint Association (ACA) issued a statement saying that the European chemical Administration (ECHA) risk assessment committee (RAC) has submitted an advisory opinion to the European Commission (EC), suggesting that titanium dioxide be classified as a category 2 (animal evidence) inhaled carcinogen, and the detailed reasons for this advisory opinion will be published within a few months, After that, EC will consider and issue the final classification requirements. In this regard, a considerable number of industries have raised concerns that the basis of this opinion is flawed and there is no effective risk evidence against humans. In addition, it should also be considered that the relevant risks are not applicable to products prepared with titanium dioxide, such as coatings, in which titanium dioxide has been embedded in the mixture

ACA believes that any hazard evaluation of titanium dioxide should be based on science. ACA recently submitted a brief statement to the World Trade Organization (WTO), pointing out that it is unnecessary for the EU to classify titanium dioxide as a carcinogen, and may unnecessarily restrict or even eliminate some products in some international trade. ACA is coordinating with the WTO through the U.S. trade representative and will jointly submit relevant opinions with other industry associations

ACA also supports the position of Titanium Dioxide Manufacturers Association (TDMA), which is trying to promote the EU to treat this classification problem scientifically and rigorously, and cooperate with many downstream industries to ensure the negative use of titanium dioxide

report of the Canadian paint and Coatings Association (CPCA)

after receiving the notification from ECHA, the Canadian paint and Coatings Association (CPCA) issued a report saying that the European risk assessment committee issued a "advisory opinion" that titanium dioxide needs to be listed in the EU as a "category 2 carcinogen" under the CLP (classification, labeling and packaging regulations). As a common inorganic compound used in white pigments, titanium dioxide is used in many products such as paint, coating and ink. In the world, the coating industry is the largest user of titanium dioxide, and 60% of the annual output of titanium dioxide is used in coating production

the detailed reasons for this opinion will be published in the next few months and submitted to the European Commission. This issue will still be fully considered before it is finally approved. In response, Gary Leroux, President and CEO of CPCA, said, "the opinions put forward by ECHA have been widely concerned and doubted by enterprises in the titanium dioxide industry chain. Experts generally believe that nearly 3000 scientific studies and tests have been supported, and that the basis of this opinion is flawed."

cpca reported that the CLP process is an ongoing regulatory plan to coordinate the classification of substances with hazardous properties within the scope of EU products, which will affect the labeling, use restrictions and worker protection of these substances. However, the focus of the CLP classification proposed this time is to consider any risks attributed to dust exposure, rather than exposure to formula products (including paints and coatings), Because titanium dioxide in these products is already in the mixture, it will not cause harm

cpca also continues to advocate reasonable evaluation of titanium dioxide to
