There is an increase in public awareness of functional textiles, which strive to produce innovative fabrics for specific applications. A recent study introcuces Polydopamine-AgNPs coated acrylic fabric for antimicrobial and antioxidant textiles.

Acrylic polymer, a significant synthetic fabric used in the textile industry, was selected to provide it with multifunctional characteristics. For this purpose, the acrylic fabric was functionalised with amidoxime groups to serve as ligands for immobilising silver ions so that it can be further in situ reduced to AgNPs. Polydopamine (PDA) has the advantage of being an ion binding and reducing agent by virtue of its phenolic hydroxyl groups capable of reducing silver ions to AgNPs, and it was exploited in the study for imparting the acrylic fabric with antimicrobial and antioxidant properties. Additionally, glucose as a reducing agent was also used to form AgNPs-loaded amidoximated acrylic fabric. The pristine, amidoximated, PDA-coated AgNPs-loaded amidoximated, and AgNPs-loaded amidoximated acrylic fabrics have been characterised using ATR-FTIR, SEM, EDX, and tensile strength. All fabric samples were assessed as antioxidants using DPPH and FRAP assays.

Excellent antioxidant and antimicrobial properties

Antimicrobial properties against Pseudomonas Aeruginosa, Staphylococcus aureus, Escherichia coli and Candida albicans were also evaluated using broth assay. An almost complete killing (99.99%) of the pathogenic Gram-negative Escherichia coli was achieved using PDA-coated AgNPs-loaded amidoximated acrylic fabric. The overall results indicated that the composite nanocoating using PDA-AgNPs showed good tensile strength and excellent antioxidant and antimicrobial properties to suggest the viability of PDA-AgNPs coating of fabrics for possible application as biomedical textiles.

The study has been published in Journal of Coatings Technology and Research, Volume 20, Issue 3, May 2023.

The European Union Innovation Fund has selected Project Air, a unique production facility for sustainable methanol in Stenungsund, Sweden, as one of 17 large-scale green tech projects to be granted more than EUR 1.8 billion.

Project Air, which is a collaboration between Perstorp, Fortum and Uniper, has applied for EUR 97 million and the total investment is expected to amount to more than EUR 230 million.

According to a press statement, Project Air is “a gamechanger” for the chemical industry, moving from fossil raw materials to recycled and bio-based feedstock, thereby enabling sustainable chemical products to a large variety of industries and end products. At full capacity, it is intended to reduce global CO₂ emissions with close to 500,000 tons from today’s levels, corresponding to 1 percent of current emissions in Sweden.

Large-scale production by 2026

Project Air is based on innovative usage of existing technology in a large-scale industrial application. To produce sustainable methanol, the facility utilises significant amounts of CO₂ and other residue streams recovered from Perstorp’s ongoing operations, biogas from new dedicated plants together with hydrogen from a new large electrolysis plant. Further, existing wastewater treatment will be utilised as feed water for the electrolysis. All electrical energy for the combined project will be renewable based. The ambition is to start up large-scale production by 2026.

Project Air will be built at Perstorp’s existing facilities in Stenungsund, strengthening the regional chemicals industry cluster, Hållbar Kemi 2030. The sustainable methanol from Project Air will be used to produce chemical products which in turn are used in a variety of applications in several industries and businesses. It’s ultimately about making thousands of end-products more sustainable, from paints and mobile screens to fabrics.

Emma Stone is embracing her dark side once more. When we last saw the star at the Cannes Film Festival, her hair was a warm auburn shade—a color the Oscar winner returns to again and again. However, it appears that she's taken a cue from Bella Baxter and gone back to a darker tone for the New York premiere of her new movie Kinds of Kindness.

While Stone's hair still has a slight reddish sheen to it, it's definitely more brunette than red these days. The color is a combo of espresso brunette with a red undertone, which brings out Stone's light green eyes. It's as though her Cannes color was bumped up a few levels to bring the drama; Stone's go-to colorist and hairstylist Mara Roszak called her look “vamp goddess,” which definitely tracks with the dark hair and black gown with sheer polka dot and net panels. Roszak styled Stone's hair simply, tucking it behind her ears and and adding a hint of bend and product for a damp look. Makeup-wise, Stone kept it equally simple with a pretty peach blush and pink lips.

Stone is one of the biggest color chameleons in Hollywood. She's a natural blonde and occasionally goes back to her roots, but seems to love red shades the most. Stone often swaps colors for specific roles; for example, she was platinum blonde for her role as Gwen Stacy in the Spider-Man movies and a redhead in La La Land, though Stone returned to her natural blonde shade in spring 2023, when she debuted a bright, sunny blonde bob. It's been awhile since she's been super dark brunette, but we'd be remiss not to mention her Poor Things character Bella; Stone wore nearly four feet of jet-black hair extensions and zero makeup for the performance, which won her her second Best Actress Oscar. Is this fresh darker color for a role or is Stone just flipping the script on the whole “going blonde for summer” thing? That's a TBD for now!

According to Gianluca Di Marzio, Brazilian forward Neymar could leave Barcelona for PSG after Les Parisiens made an enormous salary offer to the player which has left FCB feeling very worried.

PSG are ready and willing to pay the €220m release clause in the player’s contract and have offered him an enormous provisional salary deal.

Barcelona have sent their top negotiator, Sanllehi, to Brazil, who has been in the country since Friday and will spend the whole week there in a bid to convince Neymar’s agents about signing a contract extension.

Barcelona are really struggling to deal with the situation at present.

Delegated Regulation (EU) 2023/707 introduces new hazard classes for endocrine disruptors (EDs), PBTs/vPvBs andPMTs/vPvMs. By Janina Rickers and Dr Robert Zabel, Umco.

On 20 April 2023, an amendment to Regulation (EC) No. 1272/ 2008 and, with it, new hazard classes, came into force. The latter are being introduced for endocrine disruptors (EDs) and for substances that are persistent, bioaccumulative, toxic (PBT); very persistent, very bioaccumulative (vPvB); persistent, mobile, toxic (PMT); and very persistent, very mobile (vPvM).

The regulation is seeking to provide better protection for humans and the environment. This amendment of the CLP Regulation is a key pillar of the EU Chemicals Strategy for Sustainability (CSS) and thus also of the Green Deal.

The new hazard classes

The new hazard classes being introduced are:

• Category 1 and 2 endocrine disruption for human health
• Category 1 and 2 endocrine disruption for the environment 
• PBT (persistent, bioaccumulative, toxic) / vPvB (very persistent, very bioaccumulative)
• PMT (persistent, mobile, toxic) / vPvM (very persistent, very mobile)

Endocrine disruptors (EDs) have the potential to interfere with the natural hormone system of humans and animals, with adverse consequences for health and development. There are many different ways in which a substance exerts an adverse effect on the hormone system and these can be difficult to demonstrate.

Allocation into one of the two categories within the endocrine hazard classes is similar to the procedure for carcinogenic and mutagenic substances:

• Category 1: Known or presumed endocrine disruptors, with evidence demonstrated of endocrine activity, an adverse effect and a link between the activity and the adverse effect.
• Category 2: Suspected endocrine disruptors for human health. Where there is reasonable doubt about effects or evidence, the substance is classified in Category 2.

The Umwelt Bundesamt (Federal Environment Agency) defines PBT/vPvB substances as those which “degrade very poorly in the environment (i.e. are persistent), accumulate in organisms and thus in the food chain (i.e. are bioaccumulative) and are poisonous (i.e. toxic) to humans or organisms in the environment” (www.umweltbundesamt.de/service/uba-fragen/was-sind-pbtvpvb-stoffe).

PMT/vPvM substances are “poorly degraded by the environment, are mobile enough to enter the water cycle through natural or artificial barriers and are toxic.”

The new hazard classes are European classifications and so are not anchored within the Globally Harmonised System (GHS). Consequently, there will be no new pictograms, as they, like H and P phrases, are determined by the GHS. However, a working document for discussion of the new hazard classes at UN-GHS level has already been submitted. It remains to be seen whether the hazard classes will also be adopted into the UN-GHS system.

Data situation

Crucial to any classification and labelling of substances and mixtures is a knowledge of their intrinsic properties. REACH Regulation (EC) No. 1907/2006 has significantly improved the data situation for many substances in recent years. For all registered substances and to an extent depending on the registered tonnage band, information on the physicochemical and (eco)toxicological properties must be generated and submitted to the European Chemical Agency (ECHA).

There is already a good amount of data available for the new PBT and PMT hazard classes, in particular, as the determination of a substance’s PBT properties already forms part an element of a REACH assessment. And some of the criteria relating to classification into the hazard classes are standard under REACH as well. For example, registrants have to submit information on degradability (persistence), bioaccumulation and chronic (aquatic) toxicity. What is more, data may already be available on mobility. The classification criterion here is the partition coefficient between water and organic carbon (log-Koc) of the soil or sediment.

There is comparatively less data available for the categories of endocrine disruption for human health and the environment. Both of these categories are based on established scientific criteria (WHO/IPCS) for the identification of endocrine disruptors. There has been no standard requirement on this forthcoming from REACH as yet. This situation will very likely change under the upcoming amendment to the regulation and REACH will be extended to include specific (eco-) toxicological tests and alternative methods for these two endpoints. However, it will probably take some time for the resulting data to find its way into the supply chains. Even then, demonstrating the specific mechanism of the endocrine disruption will remain the greatest challenge.

Apart from the data specifically needed for classification, the REACH regulation also mandates the generation of additional data that can prove helpful with the weight-of-evidence determination. For example, registrants must submit information on the octanol-water partition coefficient, ready biodegradability and short-term aquatic toxicity for tonnages of 1 t/a and above.

Transition periods

Delegated Regulation (EU) 2023/707 has been in force since 20 April 2023. Substances placed on the market for the first time must therefore be classified and labelled accordingly by 1 May 2025. The transition period for mixtures lasts until 1 May 2026 while the corresponding deadlines for substances and mixtures already placed on the market are 1 November 2026 and 1 May 2028, respectively.

Problems

As already outlined, it can be difficult to make an unequivocal assesment of endocrine properties. The delegated regulation stipulates that the classification into these categories be based on an assessment of the total weight of evidence using expert judgment.

Another problem that must not be overlooked is the particular approach being adopted by the European Union in introducing the new hazard classes. This deviation from the United Nations system could create communications problems in the supply chain and it complicates the harmonized, comparative assessment of hazards. Companies will now have to carry out a vast amount of testing, as tests are mandatory for all products, irrespective of the tonnage band. Critics claim that this could disadvantage EU industry and that it is at odds with the objectives of the Chemicals Strategy for Sustainability. In the worst case, they say, it might even lead to a relocation of production to countries with a lower level of protection.

Conclusion

With the introduction of the new hazard classes, the EU is sending out a clear signal about the zero-pollution strategy of the CSS. The new hazard classes can help with the identification and labelling of substances that pose a potential risk to humans and the environment. A great deal of new data will have to be gathered in the years ahead, as the tonnage limit has been abolished and data must now be generated from levels of 1 t/a and above. That being said, however, until this data is available, a substance is deemed to be unclassified if there is no data available on it.

A new study presents an efficient and versatile approach for producing durable antimicrobial fabrics. The modification has little or no influence on other properties of the fabric.

Silver nanoparticles (Ag NPs) are one of the most popular antibacterial agents, but Ag NP-modified antibacterial fabrics often show poor laundering durability owing to the weak binding force of Ag NPs to the fabric. In a new work, a hydrothermal synthesis of catechol formaldehyde resins (CFR) and Ag NPs from catechol, hexamethylenetetramine, and AgNO₃ was developed, and a kind of coating called Ag/CFR was constructed in situ on the surface of cotton, polyester, polyamide, and their blended fabrics.

Versatile approach

All the modified fabrics presented high antimicrobial activity with superior laundering durability, achieving a bacteriostasis and fungistasis rate of 99.99 % against S. aureus, E. coli, and C. albicans, even after 50 laundering cycles. Ag/CFR coatings had little influence on the mechanical properties, air permeability, and feel of the fabric. All the antimicrobial fabrics showed low cytotoxicity to NIH3T3 mouse fibroblasts and contained no residual formaldehyde. According to the researchers, their work provides an efficient and versatile approach for producing durable coatings for antimicrobial fabrics, which can be widely applied to clothing, bedding, and decorations.

The study has been published in Progress in Organic Coatings, Volume 176, March 2023.
