Thinking global – acting local: the challenges of customisation in an era of globalisation

In an era of globalization, frontiers are disappearing, and brands are now speaking to wider audiences. However, geographical and cultural specificities are still shaping trends and ingredients innovation within the Beauty industry. Being aware of these specs might determinate the success of your product, especially since the emergence of Millennials and GEN-Z consumers who demand products personalized to their personal tastes and needs. M. Massé will present the actual panorama of the main international and local trends around the world, focusing on the particularities and relevant characteristics of each geographical area in terms of ingredients, routines, formats, etc. Discover some of the most important insights to help you develop products that are both efficient and relevant. Straightforward solutions meant to reach your target in the most effective ways.

Body odor management. Fragrance technology to solve sweat issues

The human body generates a wide variety of odors often considered socially problematic and interpreted as a lack of hygiene. Society is demanding solutions, however real effectiveness is difficult to reach. The majority of body odors are related to sweat and bacterial growth which means a very complex problem with many responsible factors, such as genetics, alimentation, stress, temperature or humidity. Fragrances can contribute to mitigate malodor issues and Eurofragance has developed solutions to eliminate odors generated by our body. They are based on specific combinations of selected and unique materials and delivery control of the fragrance.

Biodegradability: a Green alternative for the fragrance industry

We have a global environmental problem with waste. Biodegradability is a complex process which occurs naturally in our planet. Can biodegradability helps us to fight and reduce the waste problem? What can we do in the beauty and fragrance industry to be sure our products are not harmful to the environment if they end up in the nature?

Encapsulate or not encapsulate that is the question!

Microcapsules are small particles which contain an active agent or core material surrounded by a coating or shell. The utility of microcapsules for efficient cargo storage and targeted release is of considerable importance in self-healing materials, nutrient preservation, agricultural applications, fragrance release, and drug delivery. One of the most challenging tasks and the ultimate purpose of developing delivery systems are to modulate the release of encapsulated cargo substances. Strategies such as heat treatment, pH change, magnetic fields and light-induced morphology change have been used to alter the shell density and integrity, and then to influence capsule permeability. During the lecture drawbacks and challenges in perfume encapsulation technologies and product stability will be discussed.

Olfactory receptors: the biological inspiration for the quantification of interacting cognate odorants

This study aims to improve our understanding of the interaction between olfactory receptors and odorants to develop highly selective biosensing devices. Natural nanovesicles (NVs) from Saccharomyces cerevisiae, ~100 nm in diameter, carrying either the human OR17-40 or the chimpanzee OR7D4 olfactory receptor (OR) tagged with the c-myc epitope at their N-terminus, are presented as model systems to quantify the interaction between odorant and olfactory receptors.

Meet who is producing herbal substances in Catalonia

In 2019 a total of 454 hectares of aromatic and medicinal plants cultivation were registered in Catalonia, mainly of fresh herbs and various aromatic herbal species destined mainly to the obtention of dry herbs. In order to give relevance to this sector, the Group of Aromatic and Medicinal Plants of the Centre of Forestry Science and Technology of Catalonia elaborated a database of the current production of aromatic and medicinal plants in Catalonia, using both own and public data, and with the information provided by identified producers.

Sensory approach to measure fragrance perception

Cosmetics is a world based on the senses. The fragrance in a cosmetic product is a determining factor to seduce the consumer, is a key aspect of these first impression that determines the acceptance or rejection of a cosmetic product. This decision depends on a variety of factors, some of them directly related to the product itself, some to the person who choose and consume it, and other factors are linked to the environment where the evaluation is carried out. Getting to combine a good sensory acceptability of the product with its efficacy and safety plays a fundamental role in the development of new cosmetic products. Raw materials, physical properties and the structure of the formula influence the physiological perception (colour, texture, scent ...), which can be quantified using trained panels. This physiological perception of the product, together with the branding information, previous experience, attitudes and beliefs, influences the consumer's response, which can lead to acceptance or rejection. Here are discussed different methodologies such as discriminatory, descriptive and acceptability to investigate consumer perception.

Biological deodorant: A new strategy to deal with odour, respectfully with the skin and the environment

Fighting against body malodour has been such a complex controversy for humans. Different scientific methodologies have been proposed to face this issue that affects not just the physical aspect but also the emotional sphere of the human being. Vytrus Biotech has made a deep research in this field and proposes the concept of biological deodorant. It consists of a new and innovative mechanism of action based on plant stem cells that aims to let the skin carry out its own physiology naturally while avoiding the metabolization of the organic compounds by the skin microbiota without killing it, just controlling it.

Why do we need odour testing for the market success of cosmetic products?

This communication provides an overview of the different methodologies for measuring and characterizing odours from cosmetic products, both from the chemical and sensory perspectives. State-of-the-art methodologies for evaluating the long-lasting effect of fragrances, identifying off-notes, and the odour perception for product optimization will be discussed. These methods include: odour descriptive analysis, quantitative analysis of intensity and other attributes, hedonic tests, discriminative tests, as well as integrative approaches for the identification of odorous VOCs through GC-Sniffing-MS technique. Some practical examples on the relevance of integrating both sensory and chemical assessment techniques will be presented as well.

Machine learning for olfaction

Predicting the relationship between a molecule's structure and its odor remains a difficult, decades-old task. This problem, termed quantitative structure-odor relationship (QSOR) modeling, is an important challenge in chemistry, impacting human nutrition, manufacture of synthetic fragrance, the environment, and sensory neuroscience. We propose the use of cutting-edge machine learning methods for QSOR, and show they significantly out-perform prior methods on a novel data set labeled by olfactory experts. Additional analysis shows that the learned embeddings from graph neural networks capture a meaningful odor space representation of the underlying relationship between structure and odor, as demonstrated by strong performance on two separate tasks. Machine learning has already had a large impact on the senses of sight and sound. Based on these early results with neural networks for predicting molecular properties, we hope machine learning can eventually do for olfaction what it has already done for vision and hearing.
