What are microbes doing in your household cleaner?

You may have noticed new cleaning products on store shelves that use tiny microbes to tackle big messes.
Microbes have been used to precision clean parts, restore artworks, remediate oil spills, treat wastewater, and create powerful household and industrial cleaning product formulations.
This process of using microbes to breakdown contaminants and promote cleanliness is part of a broader concept called bioremediation. Bioremediation is a natural solution to contamination mitigation that processes waste in an environmentally friendly way.
This article will explain how microbial cleaning works, how its uses have evolved over time, and the benefits of these types of cleaners.

Innovation and sustainability from basic research to technology transfer – NanoCosPha: connecting academy to industry

Nowadays, the health concept has been extended to the overall well-being of the person and this is a trend that pharmaceuticals and cosmetics have grasped. In this context, NanoCosPha takes shape: an innovative infrastructure developed by the University of Milano Bicocca with Regione Lombardia. Made up of six laboratories, it counts technologies for the production and characterization of both pharmaceutical and cosmetic products, for the development of green extraction processes and for quality of food products and supplements. NanoCosPha is a new reality capable of overcoming the gap between the University and companies, promoting integration and technological advancements. Personalised medicine and sustainable processes are at the core of the project, with the mission to address well-being in all its aspects.

Cosmetic extractions

The formulation of products for the personal care market is in the process of changing the “rules of formulation”. Historically little attention was paid to the sources of the raw materials that are used to formulate products. The driving forces were delivery of the claimed benefits and cost. More recently, naturally derived products earned a place as one of the drivers in formulations. Extracts of cosmetically active (i.e. non-drug) are of more and more attractive to formulators. Generally, botanical products and extracts are a rich source of vitamins, antioxidants, essential oils and oils, hydrocolloids, proteins, terpenoids and other bioactive compounds (1).

Sustainability for cosmetic ingredients

The new demands from ‘green’ consumers are pushing cosmetic companies to get more sustainable, by combining the search for the effectiveness of their products with the use of ingredients and technologies that respect environmental and social sustainability systems. From the production of natural ingredients from renewable sources to the development of new products derived from waste or the choice of biodegradable or recyclable packaging, the cosmetics industry is demonstrating an increasing concern for the environment and is keeping pace by adapting ingredients, materials, practices and production systems.
This article focuses specifically on the sustainability of cosmetic raw materials along the supply chain. The piece explores the most sustainable sourcing and processing methods that can reduce the consumption of resources, energy and polluting chemical waste, without forgetting the importance of supporting local communities. Moreover, the article highlights the benefits of certifications, which allows greater transparency and assurance towards consumer needs. The NATRUE certification supports sustainability and ensures the quality of the natural and organic cosmetics sector, by offering users a more informed and responsible choice.

The sunscreen: a complex evaluation

Evaluating the performance of sun care is a complex task considering in-silico, in-vitro, in-vivo or hybrid methods. The criteria that have the most influence on the performance of these products include the composition, repartition, photostability, absorbance, and distribution of inorganic and organic filters, as well as the galenic properties of the product (spray, compact powder, oil, cream, etc.). The performance is also impacted by other factors. Harmonizing test methods between and within laboratories ensures the highest quality of sun care. Unifying global reference methods and labelling rules will also ensure that human health (e.g., nano, and endocrine disruptors) and the environment (ecotoxicity testing, coral protection) are respected.
