External Collaboration

Advances are made daily in safety research. To be able to conduct evaluations in the most appropriate way, it is essential to acquire the most-up-to-date technologies and information and to share Shiseido's technologies with experts. That is, researchers in safety assurance at Shiseido have been working with outside experts in a wide range of activities. Some of those activities are described below.

Various collaborative activities with individuals outside the company

・Interactions with outside experts

Shiseido regularly undertakes consultations on safety with Japanese and foreign experts who are active in safety assurance. Moreover, as a cosmetic company, Shiseido takes the opinions of dermatologists seriously. We actively participate in safety-related activities held by academic societies.

・Industry activities

Shiseido takes part in events held by cosmetic industry associations around the world (e.g., Japan Cosmetic Industry Association, Cosmetics Europe (CE)(opens in new window.) , Personal Care Products Council (PCPC)(opens in new window.) , ASEAN Cosmetic Association)(opens in new window.) ,and actively exchange information related to safety. Shiseido also actively contributes to safety-related activities organized by relevant industry associations (e.g., Japan Chemical Industry Association, Japan Soap and Detergent Association, Japan Hair Color Industry Association) in safety-related events.

・Development of professional human resources

Researchers work in safety assurance regularly receive training at universities and public research institutions and take part in symposiums and education seminars held outside of the company to improve their levels of professional expertise and expert knowledge.

・Basic research on safety

Shiseido has also been collaborating with outside organizations on research topics such as sensory irritation, sensitive skin, and the development of hypo-irritant compounds that are the foundations of safety, and the results have been useful in our efforts to develop safe, secure and reliable products.

Shiseido’s commitment on alternatives to animal experiments

・Sharing of research findings

Shiseido shares with the public the findings obtained from years of research by publishing them on this website, in the literature and in academic conferences. In addition, Shiseido also makes all test methods available for external use, including the patented core technology of h-CLAT, developed jointly with Kao Corporation (all royalties from the core technology of h-CLAT have been donated to Japanese Society for Alternatives to Animal Experiments). Through such efforts, alternative test methods developed with Shiseido are expected to be widely used in a greater number of research institutions and are expected to see further improvements.

・Further research on alternative methods

Efforts to find alternative methods are ongoing at Shiseido with the aims of further improving precision and expanding the domain of applicability. Shiseido has also taken on the challenge in developing alternative in vitro methods for evaluating long-term systemic toxicity.

・Efforts on establishing officially acceptable methods and industry standards

Shiseido has been pushing for the establishment of an officially acceptable alternative methods for eye irritation and skin sensitization testing. Specifically, Shiseido has been taking part in the validation activities of the Japanese Center for the Validation of Alternative Methods (JaCVAM)(opens in new window.) and the European Union Reference Laboratory for Alternatives to Animal Testing (EURL ECVAM)(opens in new window.) and working as a member of the OECD’s expert team to draw up guidance proposals. The h-CLAT was listed on Economic CO-operation and Development (OECD) test guideline in July 2016. In addition, Shiseido has also been actively participating in the industry’s efforts to standardize alternative methods and to increase public awareness.
