Aspects of sustainability of topical therapy

摘要

Background: Topical compounds are an important treatment option in dermatology. Many ingredients and packaging do not yet sufficiently fulfill sustainable criteria. Objectives: This article aims to provide a compact overview of sustainability criteria of topical compounds and packaging. Materials and methods: Based on a selective literature search and personal experience, common ingredients and packaging of topical preparations are summarized. Results: Topical preparations often contain mineral oils, acrylates, silicones and polyethylene glycols (PEG), which show poor biodegradability and may accumulate in the environment. As an alternative to these non-renewable substances, plant-based fats, oils, and waxes can be used. Biopolymers such as plant-based gum, agar-agar, pectin, and biologically produced hyaluronic acid are an alternative to plastic polymers. The environmental footprint of glass as packaging material is overestimated. Currently, plastics and aluminum may be preferable when recycled correctly.
