Microplastics in Cosmetics: Open Questions and Sustainable Opportunities
AI summary Read the abstract
This review examines the role of microplastics in cosmetic products and the industry's transition toward sustainable alternatives as regulations tighten worldwide. Researchers surveyed the properties that make plastic particles useful in cosmetics, such as texture and appearance enhancement, alongside their environmental drawbacks. The study provides an overview of emerging bio-based and biodegradable replacement materials that could help the personal care industry eliminate microplastics from formulations.
The cosmetic industry is now changing or rather having an ecological transition in which formulations such as creams, lotions, and powders for make-up, skin and hair care must not contain microplastics, now a taboo word in this field. Nowadays, many companies are intensifying their research and development (R&D) work to align with recent and future legislation that provides for their elimination to safeguard the ecosystem. The production of new eco-sustainable materials is currently a hot topic which finds its place in a market worth above 350 billion dollars which will reach more than 700 billion dollars in a very short time. This review offers an overview of the main advantages and adverse issues relating to the use of microplastics in cosmetics and of their impact, providing an insight into the properties of the polymeric materials that are currently exploited to improve the sensorial characteristics of cosmetic products. In addition, the various regulatory restrictions in the different geographical areas of the world are also described, which is matter for reflection on future direction. Finally, a prospective vision of possible solutions to replace microplastics with sustainable alternatives complete the picture of the next generation personal care products to support decision-making in the cosmetic marketplace.
