In an era increasingly defined by environmental awareness and regulatory scrutiny, sustainability testing services and solutions play a pivotal role in shaping industries worldwide. This is particularly evident in the stringent measures surrounding Per- and polyfluoroalkyl substances (PFAS), microplastics, and nanoparticles - each posing unique challenges to environmental and human health. As concerns grow over their persistence and potential harm, governments and industries are under pressure to adopt comprehensive testing protocols and adhere to evolving regulations aimed at mitigating their impact.

PFAS: The path to safer products

Per- and polyfluoroalkyl substances (PFAS) are under scrutiny due to their environmental impact. While not posing direct risks to human safety, increasing consumer awareness has prompted countries to eliminate PFAS from cosmetics and packaging, leading to heightened testing requirements.

PFAS are a large group of manufactured compounds that are used in a wide range of industrial and consumer applications, including cosmetic products. PFAS are often added deliberately as ingredients in some cosmetic products to help condition and smooth the skin, making it appear shiny, or to alter product consistency and texture, etc. In addition, they might be present as unintended degradation products or impurities resulting from the production of PFAS precursors used in certain cosmetic products. Some of them are considered toxic and could be absorbed by and accumulate in the human body for a long time, acting as so-called ‘forever chemicals’ with adverse health effects.

Many countries are leading the way in eliminating PFAS from cosmetic and packaging products. PFAS methodologies and regulations are continually evolving as additional compounds are identified, and local regulations continue to expand their testing requirements for these contaminants.

Reducing Microplastic Pollution

Microplastics are everywhere on the planet. These small, solid plastic particles, made up of blends of polymers and functional additives, are more resistant to degradation. They can be formed unintentionally or deliberately, and added to products for specific purposes, which can be harmful to ecosystems and human health. It is therefore imperative to control their pollution.

In September 2023, the European Commission published Regulation (EU) no. 2023/2055 to restrict the use of microplastics on the European market. This regulation prohibits the intentional addition of synthetic polymer microparticles (microplastics) in consumer products at a concentration >0.01% (by mass).

However, exemptions have been provided, particularly, for degradable polymers according to requirements of Appendix 15. The evidence for exclusion must be made available to the authorities on request, this includes OECD test method (TG 301/ TG 310) for Ready Biodegradability. These tests determine the potential for a substance to undergo ready biodegradation under aerobic conditions, mimicking the conditions found in sewage treatment plants. The CO2 evolution is measured regularly over the test period indicating that the polymer is degraded. The substance is considered "Readily Biodegradable" if it meets the criteria within the specified timeframe.

However, there are numerous cases where it is necessary to analyse non-biodegradable microplastics when they are added internationally to consumer products.

Nanoparticles: Health concerns and regulatory responses

Considered potentially hazardous to human health, nanoparticles are used in a number of sectors, including construction, food and cosmetics.

In cosmetics, they continue to provoke debate and strict regulation. Nanomaterials, used for their unique properties such as UV protection and texture enhancement, are governed by rigorous standards to ensure consumer safety.

Indeed, international regulations apply to the use of nanomaterials, including European regulations on the Registration, Evaluation, Authorization and Restriction of Chemicals, and Californian regulations.
