In 2022, the value of the global cosmetics market was estimated to be worth USD 262.21 billion, with an annual growth of 4.2% projected by the year 2030. The justification for this growth projection lies in the increased popularity and demand for skincare and personal care products, joined by the aging of global population. Additional contributing factors include an increased awareness of fashion trends, innovations in the areas of hair coloring and skincare product formulations, and developments in the area of packaging. In spite of these beneficial market conditions, one factor that is expected to limit the expansion of the cosmetics market is the growing concern on the implications of the long-term use of cosmetics products on account of the inclusion of dangerous chemicals. Such concerns have led to strict regulations regarding the formulation of cosmetic products.
Within the European Union (EU), the sale of cosmetic products is governed by Regulation (EC) No. 1223/2009 of the European Parliament and of the Council of 30 November 2009 on cosmetic products. In addition to stipulating requirements regarding product labeling, the regulation makes it a liability to supply a cosmetic product that may be damaging to human health or contain potentially harmful substances. Furthermore, it is also an offense to fail to perform certain safety assessments and compile appropriate technical documentation.
Aside from the protection of human health, animal welfare is a factor that remains at the forefront of the minds of cosmetics consumers and regulators alike. In 2013, a ban on the testing of cosmetics products on animals came into effect within the EU, with similar regulations coming into effect in many other countries. Yet, in light of strict industry regulations, it is clear that reliable alternative test methods not using animals are required. In this context, Biobide has developed various in vivo toxicity and efficacy assays using zebrafish larvae considered New Alternative Methods (NAMs) respecting the 3Rs (reducement, replacement, and refinement of animals).
Ethical and regulatory opposition to the use of standard animal assays has resulted in an increased effort to identify NAMs, to analize whether certain chemicals and compounds used in cosmetic products are safe and effective. One of the most promising of these NAMs is the zebrafish larvae. Bearing in mind the use of animal testing in the production of cosmetic products is banned throughout Europe and in numerous other countries, it could be doubted how zebrafish can be included in the discussion surrounding NAMs. Zebrafish can be considered NAMs, because the larvae under 5-6 days post-fertilization are not yet classified as animals under the European legislation (EU Directive 2010/63/EU) due to the fact they are not feeding and swimming independently. Therefore, these individuals can be used for testing cosmetics´ toxicity and efficacy, representing a more ethical alternative for in vivo testing.
This small-scale fish has countless properties that make it ideal to be used use in preclinical assays of cosmetics:
Alluring to these advantages of this model Biobide has developed a pipeline of services during the last 18 years applicable to the cosmetic industry, taking into account the limitations that the cosmetic industry regulations impose. Thus, Biobide has developed a variety of HCS assays for toxicity including Acutetox Assay, Neurotox Assay, Teratotox Assay, Hepatotox Assays or Immunotox Assay, or Environmental toxicity Assays, among others. Also, specific efficacy assays are offered as the Regeneration Assay, the Melanin Quantification Assay, or the Antioxidant Assay. Besides, Biobide is able to offer tailor-made solutions to adapt the capacities of the company to clients’ specific needs.
The potentially harmful effects of the chemical agents used in the cosmetic industry on humans are not the only concern, as their potential of their detrimental effects on the environment are of relevance. Chemicals used in cosmetic products can contribute to water pollution or air contamination by aerosols, which are a serious global issue,with profound implications, both for the survival of aquatic organisms and for human health. This has created an urgent need for toxin surveillance, the identification of consequences of exposure, and a greater understanding of the associated biological, chemical, and genetic mechanisms.
Thus, the zebrafish model is being used for assessing environmental toxicity of chemicals. In this sense the potential effects of the chemicals used in cosmetics on endocrine disruption are of special concern. Therefore, Biobide has developed a thyroid-disruption assay for evaluating the endocrine disruptive potential of chemicals in zebrafish larvae.
Due to increasingly strict regulation, combined with ethical and environmental concerns of the consumer, players within the cosmetics industry must continuously adapt, finding new and effective active ingredients. With a product that is intended for topical application or systemic absorption, human safety is one of the top priorities when it comes to acquiring approval for innovative active ingredients and supplements. Therefore, exhaustive, economically and logistically affordable toxicity and efficacy assays are needed. In this context, zebrafish larva has emerged as a reliable, time and cost-effective NAM for toxicity and efficacy assay of cosmetic products.
To overcome these difficulties Biobide has developed a wide pipeline of services for toxicity and efficacy assays that fit perfectly to the needs of the cosmetic industry. Biobide is your reliable partner on the development of them. The aim of the company is to accelerate the R&D processes, minimize the potential risks, and hazard, and add value to the preclinical process.
