ALTEX Report: Hundreds of UK and EU Cosmetics Products Contain Ingredients Tested on Animals

Analysis published in ALTEX finds chemicals tested on animals in many cosmetic products, despite ban

Excerpted from The Guardian:

Hundreds of cosmetic products sold in the UK and Europe contain ingredients that have been tested on animals, despite bans that outlawed such testing years ago, a new analysis has shown.

Banned tests were performed on ingredients used in products including moisturisers, lipsticks, sunscreen and hair conditioner, the analysis found, with more than 100 separate experiments performed on animals including mice and rabbits.

“European customers can’t assume the products they buy are not tested on animals,” said Thomas Hartung, an expert in alternatives to animal testing at Johns Hopkins University and one of the authors of the analysis. Even products labelled as not tested on animals may contain some ingredients that are tested on animals, he said.

Alan Goldberg Named Ambassador of Compassion for American Visionary Art Museum's Healing & the Art of Compassion (and the lack thereof!) Show

Alan M. Goldberg, PhD, is Founding Director (Emeritus) of the Center for Alternatives to Animal Testing

From Rebecca Hoffberger, founder of the American Visionary Art Museum:

Years ago I devoted a year to an exhibition entitked, “Home & Beast.” As happens with AVAM’s magic, the focus on our relationship to animals and how we humans share the one home with all that lives (answer: poorly) coincided with the 25th Anniversary of CAAT. Alan Goldberg and I collaborated on a private guided tour which we led together, and he then held the dinner for the many researchers and physicians who had taken up CAAT's mission as their own.

Alan Goldberg has inspired physicians and researchers from all over the world to find and adopt non-animal testing alternatives. His attendees were powerfully moved by an exhibition so in sync with their ideals. Our national museum and education center, right from it’s initial twinkle in my eye, always sought to weave together the works and thoughts of creative visionaries throughout all aspects of human endeavor, not limited to simply visionary artists, but rather inclusive of scientists, engineers, philosophers, human rights activists, farmers—all who creatively aim to better lives.

Therefore, I have been privileged to collaborate with truly outstanding human rights activists like Archbishop Desmond Tutu, Julian Bond, Dame Anita Roddick, and Patch Adams MD; inventors and innovators like Martine Rothblatt, Ray Kurzweil, Dean Kamen, Peter Agre MD, and Abel Wolman—my hero for whom I dedicated our exhibition, “Holy H2O: Fluid Universe,”; and comedians like Matt Groening and Lewis Black who wield humor to speak truth to power.

In our new year-long focus on the twin forces of healing and compassion, the passion wedded to Alan Goldberg’s career is so expressive of intense caring to alleviate animal suffering and at an orchestrated and unprecedented scale. This makes Alan once again an ideal collaborator and worthy show Ambassador. Simply put, Alan Goldberg never fails to inspire me with his depth of sincerity and care for ameliorating life. We are so lucky to be working with him yet again.

We are also asking institutions and clergy to adopt, in their own voice, a focus on Healing and Compassion, to magnify the intention for good of our show. AVAM has never just been about art as object, but rather as mechanism to deepen understanding and inspire better action.

Healing & the Art of Compassion (And the lack thereof!) begins with a private opening on October 8, 2021. The exhibition opens for the public October 9th.

KATHRIN HERRMANN (Co-Chair and Speaker)
7.00 - 9.00 PM
S196: Barriers of Refinement Use in Practice (Theme: Ethics, Welfare and Regulation)
Refinement research has the potential to improve the lives of many animals. However, implementation of Refinement is often limited, even when Refinements are based on scientifically sound discoveries. Barriers to implementation may include: economical constraints, apprehensions about changes to data, limitations in products marketed by animal research suppliers and people (their cultural backgrounds, attitudes and beliefs towards animals). This workshop explores what is perceived as the potential barriers to implementation of Refinement, with the aim of highlighting paths forward for successful application. Real case studies will be presented to reveal existing barriers and as examples on ways to achieve change.
Abstract ID 366 - Education and training to fully Implement refinement methods in practice - KATHRIN HERRMANN


3.00 - 5.00 PM
S114: Artificial Intelligence for Risk and Safety Assessment (Theme: Innovative Technologies)
Artificial Intelligence (AI) consists of an array of methodologies that are capable of extracting complex patterns from big data. The session will discuss the basic concept and methodologies of AI applied in predictive toxicology. The 21st century toxicology has increasingly used new tools, particularly alternative methodologies which generates new data streams. With examples from risk assessment and drug development, the guiding principle and best practice of applying AI in toxicology will be discussed with a specific emphasis on application for the new data streams.

6.30 - 8.30 PM
S205: A Virtual Human Platform for Safety Assessment
The Virtual Human Platform for Safety Assessment (VHP4Safety) is a new integrated approach for assessing safety, based on quantitative information of human biology, toxicology and exposure. The VHP4Safety will form an overarching platform integrating high quality data from existing data(bases) and algorithms, as well as new data acquired within the project. During this session we dive into the topic of predictive modelling, data science, exposure assessment and advanced human in vitro models, to design a platform that reflects the Virtual Human and address the emerging societal challenge towards transition to animal-free safety assessment completely based on human data.


3.00 - 5.00 PM
S70: Challenges of Non-Animal Approaches for Food Safety & Nutrition in the 21st Century: From Inception to Application (Theme: Safety)
This session proposal aims to discuss:
  • Different applicable legislations for non-animal approaches in the food sector
  • The way food scientists approach animal and animal-free studies
  • Benchmarking of non-animal approaches in different industry sectors
  • Real life risk assessment application in food safety and nutrition
6.30 - 8.30 PM
S105: The role of clinical research on the understanding and treatment of diseases (Theme: Disease)
Clinical-based research can, for example: explore specific genes, gene sequences or patterns that may be involved in the aetiology of a disease; perform neurological examinations to identify areas involved in specific diseases; describe the biochemical and physiological changes that occur during the development of a disease; or understand relevant psychological and epidemiological factors that can play a role in the development of a disease.

Better collection, sharing, and utilisation of human-based knowledge can improve the integration of multidisciplinary approaches, understanding of the pathophysiology of specific diseases and development and testing of new therapies, whilst limiting the use of other animals.


3.00 - 5.00 PM
S177: Innovative approaches for CNS research - from brain organoids to new single cell culture methods (Theme: Innovative technologies)
A functioning central nervous system (CNS) is key for living, and ageing is a major risk factor of disfunction. With the increase in human lifespan the incidence of neurodegenerative diseases is rising. There is a demand for good models for neurodegenerative diseases, as current in vivo models have limitations and ethical concerns.

Modeling the CNS in vitro is, however, challenging. Recent discoveries in neuroscience, such as the breakthroughs of induced pluripotent stem cell technology, 3D-organotypic cultures and organs-on-chip, move the field forward. This workshop will overview how scientists are embracing new cutting-edge technologies and provide a guidemap for future developments.

3.00 - 5.00 PM
S195: Industry and public sector partnerships in education to foster the implementation of alternative methods (Theme: Ethics, Welfare and Regulation)
Abstract ID 496 - Ways to improve their effectiveness and recognition 

Newer alternative methods to animal tests in toxicology are increasingly using advanced techniques. These are sometimes more complex than historical animal tests and their appropriation by stakeholders, CROs, safety evaluators, regulatory bodies require new knowledge, equipment and also availability of the test systems. Their validation is a must but not always sufficient to be accepted everywhere. To be trusted and routinely used there is a need of communication and training at an international level for both current professionals and next generation of toxicologists. 

In this context a number of initiatives involving private companies in partnership with educational/research institutions, learned societies and nonprofit organizations have emerged to organize theoretical as well as hands-on-training of human-relevant alternative methods. This allows students, scientists and toxicologists, to quickly become familiar with newer methods and to better understand how to use the results for GHS (global harmonization system) classification or risk assessment. In these approaches the notion of partnership is crucial. On one hand, private companies, such as methods providers or end-users, have expertise and access to technologies and methods. On the other hand, public establishments, academic institutions or learned society are representative of the intended population and have legitimacy in education.

After a short presentation of some examples involving private and public/nonprofit players conducted in Europe, South America, India or China this round table will discuss some of the barriers experienced (funding, mistrust...), definition of education and training good practices (mixing theory and practice, hosting laboratory...) and ways to improve the effectiveness and recognition of these courses (university partnership, certification, webinars...). Finally, the interest of coordination and generalization of this kind of partnerships to accelerate the spread of alternative methods to animal experimentation worldwide will be discussed.

6.30 - 8.30 PM
S85: A walk through 10 years of CAAT-Europe’s highlights
The Center for Alternative to Animal Testing in Europe (CAAT-Europe), housed at the University of Konstanz, coordinates transatlantic activities to promote the development of new and improved methods in toxicology, to provide a platform for different stakeholders for exchanging ideas, and to support the 3R’s principle of human science. CAAT-Europe is going to celebrate the 10th anniversary of its foundation, with a session focused on the most relevant CAAT articles that have been published in the last years. The presentations will cover several topics, as in vitro regulatory, systemic and investigative toxicology, including the application of omics, microphysiological systems and good practice guidance for supporting a human-centered toxicity testing paradigm change. Each speaker will introduce a single publication to tell the story behind its compilation and to discuss its implication and impact on the actual and future discussion in the 3Rs field.

S84: Beyond the 3Rs: Expanding the Use of Human-Relevant Replacement Methods in Biomedical Research (Theme: Disease)
The current landscape of alternative methods calls for a strategic focus on (1) biomedical research (where many human disease processes remain unclear), (2) replacement methods (given the myriad types of models now available (e.g., organs-on-a-chip), and (3) human relevance (given problems with the current translatability of models). This roundtable will reflect this strategic focus by addressing the use of human relevant models in several areas of biomedical research, including cardiovascular disease, Alzheimer disease, autism, and cancer.

6.30 - 8.30 PM
Smart use of social media in 3Rs
Young researchers dedicate rightfully most of their time to core knowledge production via laboratory experiments, reading peer-review literature, publishing own results, attending conferences whenever possible as well as undertaking trainings on writing grants, papers among many other activities However, the promoter argue here that restricting them to this unique set of activities is jeopardizing creativity and reducing awareness of a more complex picture in science. Other fields linked with social sciences, including scientometrics and epistemological areas covered during conferences and continuous education, may contribute to a more productive working environment for young researchers. This session would be the opportunity to kick-off the discussion and tackle some of these "secondary" topics. This was first covered in the following article "The use of social media in scientific research and creative thinking" by Busquet & Vinken


3.00 - 5.00 PM
S216: Animal Experimentation: Working Towards a Paradigm Change (Theme: Ethics, Welfare and Regulation)
New human biology-based tools should facilitate a strong shift away from animal experimentation. However, in research, animals are still widely seen as the default option, even though interspecies differences compromise translation to the humans. In this workshop we discuss some of the obstacles and driving forces of change. We address the vague public policy provisions regarding animal replacement; the limited education and training possibilities on human-relevant approaches; insufficient funding for the development of non-animal models; psychological lock-in and entrenchment in science; and public misinformation about animal experimentation, as well as how education, funding redeployment, and political action can drive change.
