While these functional advantages increase the performance and user experience of cosmetic products, they also bring about the search for sustainable alternatives due to their environmental impacts.

What Are Banned Microplastics in Cosmetics?

In the cosmetics industry, microplastics are microscopic plastic particles added to products to provide special texture, shine and cleaning properties. However, the fact that these substances do not biodegrade in nature and cause serious environmental and health concerns due to their damage to water and soil ecosystems has led to the ban of the use of certain microplastics in cosmetic products by many countries and regional regulatory bodies.

  • Microbeads: These plastic particles used in toothpastes, peeling products and some cleansers have been banned because they remain in nature for a long time and cause water pollution due to their sizes smaller than 5 mm.
  • Hard Plastic Granules: Granules made of synthetic polymers such as polyethylene, polypropylene and polystyrene, added to products to provide textural properties and stability, have been excluded from use on the grounds that they are not biodegradable and trigger environmental pollution.
  • Synthesized Polymer Particles: These particles, produced in certain micro sizes and added to formulations to provide aesthetic and structural properties, have been restricted by regional regulators such as the European Union, preventing their use in cosmetic products.

Cosmetic Safety and Microplastics

While microplastics are used in the cosmetic industry to provide special texture, shine and stability to products, they also cause significant discussions in terms of cosmetic safety. Although these plastic particles are found in a wide range of products from skin care products to make-up materials, they can cause long-term environmental pollution because they do not biodegrade in nature. Furthermore, the chemical components contained in microplastics have the potential to cause allergic reactions, irritation and other health problems when in direct contact with the skin. These risks to which users are exposed increasingly bring the role of microplastics to the forefront in the safety assessments of cosmetic products.

Increasing environmental sensitivity and public health concerns around the world have led to strict regulations on the use of microplastics. Many regions and countries have made it mandatory to remove microplastics, especially those under 5 mm, from cosmetic products and use more sustainable alternatives instead. This situation creates an opportunity for both manufacturers to accelerate reformulation processes and to offer consumers more reliable and environmentally friendly products. Thus, cosmetic safety has become a critical area of ​​consideration for microplastics, both in terms of improving product formulations and protecting ecosystem health.

Are There Microplastic-Free Cosmetics?

Yes, there are cosmetic products that do not contain microplastics. Thanks to increasing consumer awareness and environmentally friendly production approach, many cosmetic brands use natural and biodegradable alternatives instead of synthetic microplastics in their formulations. In these products, components such as natural exfoliants, plant fibers, ground seed shells or sea salt are preferred, offering solutions that are both suitable for skin health and environmentally friendly. Thus, users have access to quality and sustainable cosmetic products and have the opportunity to minimize environmental impacts.

What is Microplastic Testing in Cosmetics?

Microplastic testing in cosmetics is a comprehensive laboratory analysis applied to determine the presence, distribution and properties of unwanted microscopic plastic particles in product formulations. These tests are carried out with methods such as modern microscopy, spectroscopy and chromatographic techniques, and the size, density and chemical structure of the microplastics in the product content are examined in detail. Thus, while aiming to ensure consumer safety and environmental awareness, it is also verified whether cosmetic products comply with their label and content declarations.

How to Perform Laboratory Testing for Cosmetic Microplastics?

Laboratory testing of cosmetic microplastics provides important data for consumer safety and environmental sustainability by revealing the presence, size distribution and chemical structure of plastic particles in product formulations. This comprehensive analysis involves several key steps, from sample preparation to microscopic and spectroscopic examinations; each step enables detailed characterization of microplastics, contributing to the accurate labeling of product quality and content.

  • Sample Collection and Preparation: Representative samples are taken from the cosmetic products to be tested and a homogeneous mixture is obtained with solvent or suitable solvents to isolate microplastics in the product.
  • Sample Extraction and Digestion: Chemical digestion or extraction techniques that break down the organic matrix of the product are used to release microplastic particles; this step allows the separation of plastics in complex formulations.
  • Filtration: The resulting solution is filtered using filters of specified porosity; this process separates microplastics from other components and collects them on the filter surface.
  • Microscopic Examination: Collected particles are observed with high-resolution devices such as optical microscopes or scanning electron microscopes (SEM); thus, the size, shape and distribution characteristics of the particles are determined.
  • Spectroscopic Identification Analysis: Using methods such as FTIR or Raman spectroscopy, the chemical compositions of the particles detected under the microscope are analyzed; thus, the types of plastics and other chemical structures within the formulation are confirmed.
