Plastics in dermatology

In everyday medical practice, a lot of plastic waste is produced in patient care, from syringe needles to elaborate surgical sets, gloves, masks and laboratory supplies. In addition, in the routine of a dermatological practice or clinic, numerous plastic-packaged samples for care products of various origins play an important role in patient care.

There are over 200 different types of solid plastic of varying composition. Plastic is omnipresent and has been accumulating in the ocean for decades via rivers, sewage and rainwater. It is currently estimated that there are already 14 million tonnes of microplastics on the seabed.

Most of these substances are not biodegradable at all or only with difficulty and, depending on their size, cannot be filtered out of wastewater in urban areas via sewage treatment plants. These substances end up back on the plate via the food chain.

Basically, plastic is weighted differently:

• Macroplastic in the form of packaging material such as tubes, bottles and jars.
• Microplastics as solid synthetic compounds of various compositions up to a maximum diameter of 5 mm. These fall as primary microplastics in the formulation of externals, e.g. as solid substances such as abrasive particles, pastes and powders. Furthermore, the more common liquid polymers are also listed here, which can be contained in externals, e.g. as emulsifiers and preservatives. Secondary Microplastics on the other hand, is created from macroplastics by abrasion and decomposition processes caused by sun and wind.

For a few years now, there has been increasing evidence that some of these substances have harmful effects on health. These include, for example, allergens such as acrylates, tumour-inducing parabens, hormone-active substances such as endocrine disruptors and more Ingredients of sunscreen productswhich has been proven to lead to the death of coral reefs worldwide.
