“Nanomaterials Very Unlikely To Damage Skin If Topically Applied, Says EPA”
Nanomaterials-very-unlikely-to-damage-skin-if-topically-applied-says-EPA_strict_xxl

“The risk of topical products containing nanomaterials, such as sunscreens, damaging or penetrating the skin is very limited, according to a new report compiled by the Danish Environmental Protection Agency.
According to the ‘Better control of nanomaterials’ initiative, the health dangers come from ingesting or inhaling, and that topical cosmetics use is generally considered safe.
Nanomaterials have been under scrutiny over recent times as there was a fear that they could enter the body through absorption through the skin. Nanomaterials such as zinc oxide are often used as UV filters in sunscreens, and the new report suggests there is no reason to doubt their safety if topically applied.
“Damage to the skin or absorption of nanomaterials through the skin is very limited,” says the EPA report. “The report stresses that on the basis of current knowledge, there is no risk associated with the uptake of nanomaterials through the skin. “
The report goes on to highlight the benefits of using sunscreen and that these benefits need to be compared to the possible risks associated with exposure by ingestion.
The study only slight concern raised by the EPA, is that one of the studies it looked at indicates that based on conservative worst-case assumptions, nanomaterials in sunscreen products may be ingested (one example is sun protecting lip balm) and that this can be linked with a possible risk.
The initiative also suggests that there is no significant risk to the freshwater environment from current usage of nanomaterials and their potential for release to the environment. (…)”

« ECETOC Publishes Case Studies On Nanomaterials Grouping And Testing »
ecetoc« The European Centre for Ecotoxicology and Toxicology of Chemicals (ECETOC) has published case studies on the grouping and testing of nanomaterials. They are based on the decision-making framework it published earlier this year (
The centre says that for 21 of the 24 materials tested, the non-animal testing tiers correctly predicted the outcome of the animal tests. As a result, it says, the framework will allow nanomaterials to be assessed with animal testing as « a very last resort ». (…) »

“The Swedish Chemicals Agency Proposes Reporting Requirements For Nanomaterials”

kemi

“The Swedish Chemicals Agency proposes that companies should have a duty to report if chemical products contain nanomaterials. The aim of this proposal is to improve knowledge about which nanomaterials there are on the Swedish market.
“Research has shown that nanomaterials might pose a threat to health and the environment, but there is currently insufficient knowledge in this area. Reporting requirements would enable us to obtain more information on the quantities and types of nanomaterials used in Sweden,” says Victor Björkgren, Scientific Officer at the Swedish Chemicals Agency and Project Manager for the government assignment on nanomaterials.

There has been a long-standing requirement in Sweden for companies to register the content of their chemical products to the Swedish Chemicals Agency’s Products Register, but no special mention of nanomaterials has been required. The Swedish Chemicals Agency’s proposal, which is being submitted to the government today, means that companies reporting products to the Products Register must also state whether these products contain nanomaterials.
“By having reporting requirements for nanomaterials, we will be well prepared should new research show that there are problems with nanomaterials of which we are not aware at present. The information compiled in the Products Register would give us a good basis on which to make changes to legislation or take other measures in the future, if these are needed,” says Victor Björkgren.

The Swedish Chemicals Agency proposes that companies with a turnover of less than SEK 5 million per year should be exempted from the reporting requirement during a period of evaluation. These companies should only need to tick a box if they believe that their products contain nanomaterials. During the period of evaluation, the same exemption should also apply to nanomaterials in the form of pigment.
In January 2015 the Swedish Chemicals Agency was assigned by the government to investigate a way of formulating the reporting requirement to provide information on nanomaterials in chemical products and articles. The response being provided to the government today also includes proposals for statutory changes, an impact assessment and an analysis of the EU legislation. Several other EU countries have already introduced or are planning to introduce their own solutions for gathering information on nanomaterials. The European Commission is also investigating a possible common register within the EU. (…)”

Réalisé par Avicenn avec le soutien du ministère de l’Ecologie, du développement durable et de l’énergie, de la Fondation de France, du Centre Médical Inter-Entreprises Europe (CMIE) et du Conseil Régional Rhône-Alpes.
Les nanomatériaux sont très présents dans nos vies : comment les repérer, et quelles sont leurs conséquences sur notre santé ?
Dans de nombreux domaines – automobile, cosmétiques, pharmacie, optique, agriculture et alimentation, etc. – les industriels font de plus en plus appel aux nanotechnologies qui bénéficient de financements publics et privés conséquents.
Or, les impacts sanitaires et environnementaux des nanomatériaux sont encore insuffisamment développés, mais déjà des effets néfastes très préoccupants ont été mis en évidence : les nanomatériaux ont été reconnus comme toxiques pour les tissus humains et les cellules en culture. La dissémination à large échelle de nanoparticules dans l’environnement est elle aussi problématique. Aucune réelle restriction n’est aujourd’hui mise en œuvre par les pouvoirs publics.
Par ailleurs, il n’y a pas de traçabilité ni d’étiquetage fiables : il est aujourd’hui impossible d’identifier l’immense majorité des produits aujourd’hui commercialisés contenant des nanomatériaux.
Ce livre s’adresse aux citoyens, mais aussi aux associations impliquées dans les secteurs de la consommation, de santé et de l’environnement, ainsi qu’aux acteurs du domaine de la santé au travail. Pour que la vigilance soit de mise, chez vous, pendant vos courses et sur votre lieu de travail !(…)”

Ciel, Öko-Institut and Ecos Make Joint Proposals on Nano

« Characterising nanoparticles is key, say bodies.

Proposed REACH annex amendments for nanomaterials need more detail, according to a position paper by the Centre for International Environmental Law (Ciel), the European Environmental Citizens Organisation for Standardisation (Ecos) and the German Öko-Institut.

As pressure grows for the European Commission to revise REACH annexes for nanomaterials, the paper discusses the Commission’s proposed amendments, as presented to the competent authorities’ sub-group on nanomaterials (CASG-nano) in 2014 .

The organisations welcome the inclusion of a nano definition in REACH Annex VI. However, they point out that proposals for characterising nanoforms only cover minimum requirements. “Important information is missing”, including particle-size distribution outside of the 1nm to 100nm range, says the paper.

Surface chemistry and charge, and whether particles form clumps and clusters, during use and release, should also be considered, it adds. It also points out that information on surface treatment, coating or functionalisation remains “extremely limited”, despite being relevant for risk assessment.

The position paper refers to a 2014 study by Risk and Policy Analysts (RPA), pointing to a lack of nanoform information in registration dossiers.

Last week, Geert Dancet, head of Echa, said that 40% of dossier compliance check decisions are currently appealed and that some companies are even challenging the premise that REACH covers nanoforms.

Ciel and partners suggest that physico-chemical and (eco-)toxicological information should be included in registration dossiers, when nanoforms are used in consumer products. “With this amendment, an important loophole regarding the risk assessment for most of the existing nanomaterials … would be closed,” they write.

Nanoparticles should be fully characterised before grouping for read-across and toxicological assessment, stresses the paper. “Allowing the grouping for (eco)toxicological assessment of non-characterised nanoforms would defeat the purpose of most of the proposed amendments,” it says. “It is scientific nonsense to group several uncharacterised materials for the purpose of hazard assessment.”

At its 15th meeting on 4-7 November, the OECD’s Working Party on Manufactured Nanomaterials (WPMN) will discuss a progress report on physical-chemical properties for grouping for read-across. It will also wrap up case studies on exposure assessment for gold and silver nanoparticles.

The main focus of the meeting will be to plan the WPMN’s programme of work for 2017 to 2020. To help with this, the working party will hear presentations from various delegations, explaining particular policy challenges, said chair Peter Kearns.

At the meeting, the WPMN will also begin to review the OECD Council recommendation on the safety of nanomaterials, last agreed in 2013.

CASG-nano’s last meeting was in December 2014 . «

German Environment Ministry Outlines REACH Priorities

« Top official says ‘protect’ it from TTIP, improve dossier quality.
The environment ministry of Europe’s biggest member state has spelled out its priorities for protecting the achievements of REACH, and improving its implementation.

Speaking at yesterday’s conference in Brussels on the future of REACH, organised by nine European countries, Alexander Nies, deputy general of Germany’s federal environment ministry (BMUB), said European governments must “protect” the hazard-based elements of REACH, and its placing of the burden of proof of chemical safety on industry, from TTIP, the current EU-US talks on a new trade agreement.

His comments were echoed by Monique Goyens, head of European consumers group Beuc, who described TTIP and the European Commission’s Better Regulation programme as a “toxic cocktail” that threatens to “further delay regulation on chemicals in Europe”.

In contrast, Cefic director general Hubert Mandery called for increased cooperation with the US on chemicals, through the TTIP talks.

The BMUB is also concerned about the quality of registration dossiers, said Mr Nies, especially for endpoints such as reproductive and developmental toxicity. “Standard animal testing is the exception. But the alternative information provided is insufficient, in many cases, for most high tonnage substances,” he said.

Echa must “intensify” its dossier compliance checks and target the most important endpoints. It must also “communicate more clearly the extent to which animal testing is indispensable”, even though “this is an uncomfortable message – industry doesn’t like it, and the animal welfare NGOs certainly don’t like it.”

On authorisation, Mr Nies said that although the process was broadly working, discussion of possible changes was needed. The weighing of the economic benefits and risks of a particular use of a substance, he said, is a political task, not a scientific one, and is, therefore, not a task for Echa.

As well as registration dossier quality, a number of common themes were raised by most of the conference speakers. These included how to: help the substitution of SVHCs; weigh the need to increase material recycling against the need to restrict SVHCs and other hazardous substances; move forward on nanomaterials and endocrine disruptors; and make REACH work better for SMEs and downstream users.

An issue mentioned by competent authorities, industry and NGOs was the need to remove the competitive disadvantage faced by companies in Europe, regarding banned substances in articles. The problem is twofold: imported articles, containing restricted substances, are still appearing on the EU market; and the phase out of Annex XIV substances does not apply to imported articles.

Germany’s Environmental Protection Agency (UBA) says it would be legally possible for the EU to extend the applicability of Annex XIV to imported articles, without infringing free trade law. »

« Better Regulation Agenda Delaying REACH Implementation » Says EEB Head

« The European Commission’s “obsession” with its Better Regulation agenda is delaying the implementation and enforcement of REACH, says Jeremy Wates, secretary general of the European Environmental Bureau (EEB).

In the margins of yesterday’s EEB’s annual conference, Mr Wates told Chemical Watch that “unsubstantiated complaints from industry” about REACH costs should not be allowed to stop the regulation from achieving its goals of protecting human health and the environment.

The European Commission’s Better Regulation agenda is “at the heart of this delay”, he said. This, according to the Commission, aims to “design EU policies and laws that achieve their objectives at minimum cost”.

Mr Wates said that despite the Commission’s assertions to the contrary, this agenda suggests cuts to the “regulatory safety net that protects consumers, citizens’ health and their environment”.

The Commission is currently reviewing REACH‘s impact on businesses. It recently revealed that 35 % of 1,600 companies responding to a survey said REACH is negatively impacting their capacity to innovate.

Earlier this week, the EEB released a report from its 40th anniversary conference held last December.

It says that efforts to improve chemical safety are facing “strong push back” from industry.

“Implementation of REACH is happening at too slow a pace and key issues such as endocrine disrupting chemicals, cocktail effects and toxicity of nanomaterials remain unresolved,” it says. »
