The U.S. Department of Agriculture’s (USDA) Agricultural Research Service announced on April 9, 2024, that ARS researchers published a study revealing the ability of cotton gin waste to synthesize and generate silver nanoparticles in the presence of silver ions. ARS states that cotton gin waste, also known as cotton gin trash, “is a byproduct of the cotton ginning process and occurs when the cotton fibers are separated from the seed boll.” Using a simple heat...

On March 15, 2024, the European Commission (EC) published in the Official Journal of the European Union an amendment to the Cosmetics Regulation. The following nanomaterials have been added to Annex II (substances prohibited in cosmetic products). From February 1, 2025, cosmetic products containing these substances shall not be placed on the European Union (EU) market. From November 1, 2025, cosmetic products containing these substances shall not be made available on the EU market: The...

On August 14, 2023, the United Kingdom’s (UK) Office for Product Safety and Standards (OPSS) called for the submission of any scientific information relevant to the safety assessment of nanomaterials used in cosmetics. Article 16 of the UK Cosmetics Regulation requires that cosmetic products containing nanomaterials be notified to the Secretary of State at least six months prior to being placed on the market. These notifications may be completed via the Submit Cosmetic Product Notification...

The U.S. Department of Agriculture (USDA) announced on April 11, 2023, that its Agricultural Research Service (ARS) recently developed sustainable, machine-washable antimicrobial wipes that can be used at least 30 times for cleaning hard and nonporous surfaces. According to USDA, ARS researchers developed the antimicrobial wipes “by using raw cotton fiber that naturally produced silver nanoparticles inside the fiber in the presence of a silver precursor.” USDA states that the...

On February 1, 2023, the National Nanotechnology Initiative (NNI) will hold a webinar on the environmental, health, and safety (EHS) implications of metal nanoparticles in aquatic environments. According to NNI, the focus will be on copper and copper oxide, nickel, and silver nanoparticles. Each expert panelist will provide an overview on the current state of knowledge for a particular metal nanoparticle. The panelists will discuss methods used for identifying, measuring, and assessing the...

.The Organization for Economic Cooperation and Development (OECD) has published for comment a draft study report entitled “Applicability of the key event based TG 442D for in vitro skin sensitisation testing of nanomaterials.” Switzerland conducted experimental work with selected nanomaterials using OECD Test Guideline (TG) 442D (KeratinoSensTM) and made a basic in vitro to in vivo correlation to outline the potential relevance of the results for prediction of skin sensitisation of...

On September 13, 2022, the European Union (EU) Observatory for Nanomaterials (EUON) published a Nanopinion entitled “Can the Brain’s Gatekeeper Fight a Nano-Attack?” by Dr. Eugenia (Éva) Valsami-Jones, Professor of Environmental Nanoscience at the University of Birmingham, who co-authored an article entitled “Biotransformation modulates the penetration of metallic nanomaterials across an artificial blood–brain barrier model.” The researchers set out to explore systematically how...

On July 29, 2022, the National Institute for Occupational Safety and Health (NIOSH) published a Technical Report: Occupational Exposure Sampling for Engineered Nanomaterials. Since 2010, NIOSH has developed guidance for workplace sampling for three engineered nanomaterials: carbon nanotubes (CNT) and nanofiber (CNF), silver, and titanium dioxide, each of which has an elemental mass-based NIOSH recommended exposure limit (REL). NIOSH has also developed a practical approach to...

The Organization for Economic Cooperation and Development (OECD) has published the latest edition of the Developments in Delegations on the Safety of Manufactured Nanomaterials — Tour de Table. The Tour de Table compiles information provided by delegations on developments concerning the safety of manufactured nanomaterials. It includes the following information on developments in the United States....
