Microplastics: Invisible danger in everyday life

Microplastics are everywhere: in water, air, food—and even human blood. They're so small that we can neither see nor feel them, yet their impact on the environment and health is enormous. This invisible danger often hides right in front of our eyes, especially in cosmetic products.

❔ What is microplastic?

Microplastics are solid plastic particles smaller than 5 millimeters in size. There are two main types:

• Primary microplastics : Produced directly in this size, e.g. as abrasive particles in scrubs or toothpaste.

• Secondary microplastics : Created by the decomposition of larger pieces of plastic – e.g., packaging, textiles or tire wear.

A large portion enters our rivers and oceans via wastewater. There, it accumulates in the food chain—from tiny plankton organisms to us humans.

⚠️ Why is microplastic so dangerous?

• It does not decompose biologically but remains in the environment for centuries.

• It can bind pollutants , which are then absorbed in a concentrated form by living organisms.

• Studies show that microplastics can trigger inflammation or hormonal changes when they enter our bodies.

• New research has even found microplastics in the human brain , indicating possible risks to the nervous system – including neurodegenerative diseases or chronic inflammation.

• Animals mistake it for food – and often die as a result.

🧖 Where is microplastic found in everyday life?

• In many cosmetic products such as scrubs, toothpaste, lip care, shampoo and even decorative cosmetics.

• In synthetic textiles that lose tiny fibers when washed.

• In car tires, whose abrasion is one of the biggest sources.

Particularly insidious: Manufacturers often disguise microplastics behind names such as polyethylene (PE) , polypropylene (PP) or acrylate copolymer on the list of ingredients.

✅ How can you avoid microplastics?

✔️ Choose natural cosmetics: Look for seals like COSMOS, NATRUE, or Ecocert—certified products must not contain microplastics. ✔️ Check ingredients: Apps like CodeCheck or ToxFox help you identify suspicious ingredients. ✔️ Use solid products: Solid soaps, shampoos, or deodorants not only save packaging but often contain fewer harmful ingredients. ✔️ Use a wash bag: Special bags like the Guppyfriend catch microfibers during washing. ✔️ Avoid synthetic clothing: Natural fibers like organic cotton or linen do not release microplastics when washed.

🌿 Biork: Your contribution against microplastics

Our Biork deodorant is made from 100% natural alum stone and contains no microplastics or synthetic additives—packaged in sustainable cork instead of plastic. This way, you not only protect your skin but also the environment.

Conclusion:

Microplastics are an invisible, but not invincible, threat. By making conscious choices in your everyday life, you can actively contribute to stopping the entry of microplastics into our environment – step by step.
