Abstract
Topical compounds are an important treatment option in dermatology. Many ingredients and packaging do not yet sufficiently fulfill sustainable criteria. This article aims to provide acompact overview of sustainability criteria of topical compounds and packaging. Based on aselective literature search and personal experience, common ingredients and packaging of topical preparations are summarized. 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. The production of topical formulations without using mineral oils, silicones, acrylates, and PEGs is technically challenging. Asustainable packaging material that fulfills all relevant functionalities is not yet available. Packaging should meet high requirements regarding ecological, economic, and social factors. Better performance with respect to new opportunities in recycling and waste management should be incorporated. Overall, the legislative authorities should provide relevant incentives for more sustainable topical compounds and packaging.
