Unleashing Nature's Potential: The Future of Sustainable Beauty with Biotechnology
The sustainability imperative
Sustainability remains a pivotal trend in the home care industry. With a growing awareness of the environmental impact of daily choices, consumers are keen to opt for products that align with their eco-conscious values.
Sustainable practices have transitioned from niche to mainstream, with sustainability claims beginning to overshadow brand loyalty in the world of cleaning products.
In the cosmetics market, one of the growing trends is the development of biotech beauty in order to meet the constant increasing demand for more sustainable and/or natural ingredients. So what is biotechnology beauty definition and what is hidden behind this name?
Plants and microorganisms have always been known for their molecular richness, they are like small factories capable of synthesising a multitude of molecules of interest, for various purpose. Microorganisms are used in many fields, like food industry with for example the production of pigments by some microalgae or the production of enzyme. We can also give some examples in the pharmaceutical industry, with the production of antibiotics or anticancer molecules by some bacteria or fungi. Regarding the field of plant and especially the plant cell culture, since the first research in 1950 on Dalhia first virus-infected plant rescue, it has undergone great developments, especially in the recent years as this technology answers the sustainability challenges, we are all facing. The plant cell culture has shown some application in food with the production of some dietary or colouring agent but also in pharmaceutic industry, with for example the production of taxol.
In the cosmetic field, biotechnology is the perfect answer to the increased demand for natural ingredients as well as the need for more eco-friendly manufacturing processes. This technology allows to reply to major environmental, climatic and societal challenges. First, it only needs a small sampling from the ecosystems and as such contribute to their preservation. Compared to classical extraction, biotechnology allows their use, with a limited water quantity, no soil occupation and no use of pesticides nor fertilizers. Moreover, extraction process doesn’t use any solvent and requires less energy. As the manufacturing is done in a fully controlled environment, with very precise protocols it allows the identification and quantification of metabolites of interest and their reproducibility batch to batch. In summary, biotechnology allows a control of the life cycle from the raw material to the waste.
On the vegetal scope, after a first generation that allowed to obtain so-called primary molecules, i.e. molecules essential for the plant to live, in a controlled environment, the second generation made it possible to obtain, thanks to very specific stimulation protocols, molecules of interest produced by the plant in response to these stimuli. If in the first case it was essentially a matter of creating and amplifying a biomass, in the second, the research allowed the production of extracts with optimized and reproducible concentrations of molecules of interest. Now a new era is upon us with the third generation that is based on epigenetic.
With regards to micro-organisms, algae, yeast and bacteria have been widely used to produce active ingredients and new processes are currently developed to get similar successes with fungi that can be very challenging in term of industrialization, as well as the development of synthetic biology.
For all these reasons, more and more active ingredients are issued from biotechnology with a huge number of beauty benefits. It goes from seboregulation and microbiota balance to skin evenness, firming or IR damage protection and of course hydration and skin barrier repair with ceramides for example. It is also the case for functional ingredients like biosurfactant or gelling agent that can be obtained by fermentation.
And this is just the beginning! Biotechnology continues to open up the field of possibilities in the development of new eco-responsible ingredients. As mentioned above, the third generation of plant cell culture brings limitless opportunities. With an even more advanced chemical selectivity and the ability to orientate the metabolism in a more precise and specific way, it allows the production of active molecules that couldn’t be obtained with more traditional technologies. These molecules could be produced by the plant but this latter does not know it! Metabolic pathways are unlocked with precursors and/or specific stimulations, removing inhibitions that can be linked to epigenetic factors. In a few words, the blocking of DNA expression is removed, but not modified.
Another field of research for the future is synthetic biology. This ‘new’ technology makes it possible to produce molecules that could only be obtained from chemistry, using some solvents, catalysts, dangerous materials. Synthetic biology is a combination of biology, bioinformatics and engineering. The principle is to build and develop biological systems that do not exist in nature or re-built existing systems by modifying them. The concept is to use (bio)bricks that are standardised and able to be put together to fulfil a function. This pure innovation allows tailor-made bioproduction of recombinant proteins and peptides, antioxidants, pigments, UV filters, biomaterials, polysaccharides, … with new or optimised abilities. Thanks to synthetic biology some processes can be improved with regards to time saving, yields, so finally by reducing some consumptions and costs.
Biotechnology does not have visible limits for cosmetic, food and pharma as well as other applications like crop or biomaterial uses. For the cosmetic industry, once again, it offers more sustainable ingredients but also new ingredients because nature is amazing to produce some molecules that are very difficult to produce by chemistry for example. Of course, the objective is not to fully replace chemistry but to make sure to use the best technology to reduce impacts on the planet. And to achieve this goal the personal care industry can partner with specialised companies that have developed a strong know-how in biotechnology techniques or micro-organism culture. Together they can benefit from their scientific advances to develop innovative and sustainable active ingredients.
Looking Forward
During March 2023, Euromonitor published a Megatrends: Personalization report (4). The report concluded that “the growth of individualism and self-oriented lifestyles is influencing rising consumer expectations for highly customizable and personalized products and services. These demands are increasingly met by improvements to technology and data collection that provide consumers insights on their individual interests, lifestyles, health, nutrition, and body, with enterprising companies offering solutions to address concerns that arise from this information.” With these comments in mind, Euromonitor identified 10 of the most influential megatrends set to shape the world through 2040. Personalization is included in the 10 megatrends. We can expect personized skin and hair care to continue growth, skin care companies who enter this space will have to ensure consumers are well educated in their technology offering and that the recommended technology will provide the claimed benefits.

Efficiency at Low Temperatures: Shaping Consumer Habits
One notable approach involves engineering products that provide effective cleaning at lower temperatures. Many products were already efficient at low temperatures, but consumer habits, rooted in manual dishwashing at high temperatures, prompted a shift. Products with claims promoting efficiency at low temperatures, prominently displayed on labels, played a crucial role in changing consumer behavior. The awareness campaigns encouraged consumers to adopt lower temperature dishwashing habits, resulting in a significant reduction in energy consumption. Advertisements for these products continue to advocate for the benefits of cleaning at lower temperatures, promoting both environmental sustainability and energy efficiency.
Boosters and Laundry Disinfection: Enhancing Low-Temperature Cleaning
Adjacent to the emphasis on low-temperature efficiency is the increasing popularity of boosters in laundry cleaning. Boosters enhance the cleaning effect even at low temperatures, aligning with the industry's focus on efficiency and sustainability. Simultaneously, the rise in awareness about disinfection practices has led to a surge in the use of laundry disinfection products. This not only responds to the increased demand for disinfectant products but also serves as a method to lower washing temperatures. Consumers now have the option to achieve clean and sanitized textiles at temperatures as low as 30 degrees Celsius, marking a significant step toward sustainable and energy-efficient laundry practices.
Highly Concentrated Products: Balancing Efficiency and Affordability
Another avenue gaining popularity is the development of highly concentrated cleaning products. These formulations boast efficiency, requiring smaller amounts for effective use. The reduced packaging not only contributes to a smaller environmental footprint but also aligns with the economic aspect of affordability. In addition to environmental benefits, concentrated products have become a consumer-friendly choice, offering convenience and ease of storage.
Water-Responsible Cleaning: A Comprehensive Approach to Sustainability
A promising trend emerging in the industry is the introduction of water-responsible cleaning products. These products are designed to work efficiently while minimizing water usage. Not only do they contribute to water conservation, but they also reduce the energy needed to heat water for cleaning purposes, providing a comprehensive approach to sustainability. With consumer habits evolving, the industry is witnessing a growing emphasis on the importance of water-efficient formulations. Advertisements and promotional campaigns highlight the dual benefits of water-responsible cleaning: reduced environmental impact and lower energy consumption.
