The Safety Evaluation Center

(FUJIFILM’s Activities)

The Fujifilm Group strictly conducts the appropriate management of chemical substances in the entire process of planning, development, commercialization, production, and marketing. In this section, we will introduce the Safety Evaluation Center, which evaluates the safety of chemical substances necessary for such a mission.

The Safety Evaluation Center plays an important role in evaluating the overall safeness of various chemical substances, materials, and products developed and used by the Fujifilm Group. We are committed to ensuring the safety of chemical substances used in the following various products before delivering products that consider human health and the environment to our society. The part of such safety evaluation is carried out by the Safety Evaluation Center, an internationally recognized and highly trusted testing facility.

Role of the Safety Evaluation Center

The Safety Evaluation Center was established in 1975 as a testing unit of the Environmental Management Division to conduct safety testing for chemical substances. The role of the Safety Evaluation Center is to evaluate the safety of various chemical substances, materials, and products developed and used by the Fujifilm Group from the early stage of development to the commercialization stage in order to minimize any risks to the environment and the health of humans. More specifically, the center serves as a GLP compliant test facility that is internationally recognized and highly trusted, and conducts various tests such as testing of chemical substances for legal compliance, testing of product safety, and testing for occupational health and safety. 
Recently, the Fujifilm Group has expanded its business to include highly functional materials and healthcare products. To develop new products with high environmental quality, we also enhance and expand safety evaluation technologies. More precisely, in order to develop safe products, we have introduced a safety database environment accessible by material developers and developed advanced technologies such as toxicity screening method for cytotoxicity, gene expression, etc. and toxicity prediction methodologies based on quantitative structure-activity relationships.

Status of the Safety Evaluation Center as a GLP Compliant Test Facility

As a GLP compliant test facility, the Safety Evaluation Center conducts internationally viable and highly reliable tests.
The term “GLP” stands for “Good Laboratory Practice,” meaning a certification system for test laboratories that are reliably and functionally organized with structures and facilities satisfying certain standards. Test reports issued by a GLP compliant test facility can be used for the domestic application for new chemical substances as well as the overseas application for mutual acceptance of data by member countries. 
The Safety Evaluation Center serves as a GLP compliant test facility for the following test items in compliance with the Chemical Substances Control Act (Act on the Evaluation of Chemical Substances and Regulation of Their Manufacture, etc.):

  • Under the supervision of the Ministry of Economy, Trade and Industry of Japan (certified in 1986): Biodegradation test, Bioaccumulation test / Partition coefficient test
  • Under the supervision of the Ministry of Health, Labour and Welfare of Japan (certified in 1990): Ames test / Chromosome aberration test
  • Under the supervision of the Ministry of the Environment of Japan (certified in 2005): Algal growth inhibition test / daphnia magna acute immobilization test / fish acute toxicity test

Support for the Long-range Research Initiative (LRI)

The International Council of Chemical Associations*1 promotes the Long-range Research Initiative (LRI) with respect to chemical substances that may affect the environment and the health of humans. Fujifilm supports the LRI activities by participating as a sponsor and a committee member.

Animal Welfare Initiatives by the Fujifilm Group

In the process of developing chemical/medical products, there may be cases where experiments on animals are required to verify that such products are safe and effective in human beings. From the standpoint of animal ethics, however, animal experiments should be used only when they are really necessary. The Fujifilm Group has established the Animal Ethics Regulations and appropriately manages animal experiments in compliance with the Act on Welfare and Management of Animals and relevant ordinances. 
The director of each animal testing facility at every group company should formulate the Regulations for Animal Experiments and establish an Animal Experiment Committee. They are also required to appropriately manage animal experiments and implement educational training and self-checks*3. In addition, since 2009, employees involved in animal experiments from each group company regularly gather together to share information relating to animal ethics and facilitate improvements. 
Furthermore, the Safety Evaluation Center has been actively working on the development of alternative methods for animal testing from the standpoint of animal welfare*4.

  • *3 Some testing facilities of our group companies are certified by the Japan Health Sciences Foundation.
  • *4 3R of animal protection (Replacement: Use of alternative methods; Reduction: Reduction of the number of animals used; Refinement: Relief of animal pain)

The Safety Evaluation Center is actively developing alternative methods for sensitization testing, irritation testing, etc. from the standpoint of animal welfare*1 as well as participating in joint studies on alternative methods. We also develop prediction methodologies using computers and utilize them in actual safety evaluations.

Development of an Alternative Test for Skin Sensitization

Fujifilm has developed “Amino acid Derivative Reactivity Assay (ADRA),” an alternative test for skin sensitization to evaluate whether a chemical substance provokes an allergic reaction in the skin without using animal testing. In June 2019, ADRA was adopted in the OECD (Organisation for Economic Co-operation and Development) Test Guidelines*2
ADRA can evaluate a wider variety of chemical substances by making use of a reagent with high detection sensitivity developed with FUJIFILM’s high technology for chemical synthesis and molecular design than conventional method. 
Since ADRA has been internationally recognized as a standard evaluation method, we will further strive to widespread the new chemical safety assessment methods that can replace exsisting animal testing.

Participation in Joint Studies on Alternative Methods for Skin Irritation, Eye Irritation, and Skin Corrosion Tests

We have participated in several joint studies on alternative methods. These include alternatives to the skin irritation test using an artificial skin model*3, to the eye irritation test using an artificial cornea model*4, and to the skin corrosion test using an artificial skin model*5. In this way, we strive to contribute to the establishment of new alternative methods.
