Traditional cosmetic products often contain non-biodegradable particles that pose a threat to marine ecosystems. These microplastic particles, prevalent in products like foundation and eye shadow, contribute to environmental pollution and biodiversity loss. Recognizing these concerns, Toray has embarked on a mission to revolutionize cosmetic raw materials with their biodegradable PA4 fine particles.
Toray’s microplastic particle will biodegrade in the marine environment
The PA4 fine particles undergo biodegradation processes, wherein microorganisms such as bacteria and fungi break down the organic compounds into simpler substances, including water and carbon dioxide. While biodegradation is typically slower in marine environments compared to soil, Toray’s innovative solution offers promise in combating marine pollution and environmental degradation caused by microplastics.
In response to growing environmental awareness, regulatory bodies worldwide are imposing restrictions on microplastic usage in consumer products. Toray’s biodegradable PA4 particles align with these regulatory initiatives, providing a sustainable alternative that meets stringent environmental standards.
Toray’s proprietary technology has enabled the production of spherical polymer particles, overcoming challenges associated with the high melting point and thermal properties of PA4. Rigorous testing, including OECD 301F and ASTM D6691 assessments, has validated the biodegradability of the particles, further bolstering their environmental credentials.
With plans for commercialization by March 2025, Toray is actively collaborating with cosmetics manufacturers to evaluate the efficacy of their biodegradable PA4 particles. Additionally, ongoing research and development efforts aim to enhance particle sustainability by exploring biomass-based alternatives.
Toray’s introduction of biodegradable PA4 spherical fine particles represents a significant milestone in the pursuit of eco-friendly cosmetic raw materials. By harnessing innovative technology and aligning with regulatory standards, Toray is poised to drive positive environmental impact and promote sustainability in the cosmetics industry.
