“…These developments would certainly help address the potential data gaps related to UV filters, coral toxicity, and the impact on coral reef declines in the future. Meanwhile, the application of the EcoSun Pass (ESP) tool can already be used to formulate sunscreens that are more environmentally friendly (Pawlowski et al, 2021). It allows the selection of the most ecofriendly UV filter candidates by combining the environmental hazard profile of an individual UV filter with its efficacy to absorb UV light.…”

Ultraviolet (UV) filters used in sunscreens are among the anthropogenic substances that may enter the marine environment by both indirect (via wastewater) and direct pathways (leisure activities). Owing to the recent global decline in coral population, the impact of those UV filters on the coral health is currently under increased investigation. First results from scientists suggest that some of the filters may be toxic to various coral life stages, but an initial cross comparison with existing data from other freshwater organisms does not indicate that corals are specifically more susceptible to UV filters than other standard species. In fact, the available data leading to this conclusion is still vague and based on toxicity and bioaccumulation tests with corals, which are both still at the research stage. To facilitate a proper hazard assessment, robust experimental procedures for coral ecotoxicological studies are considered mandatory. In other words, additional steps should be taken to standardize and validate such new test systems to generate reliable results, which then can be used in regulatory decision making. Furthermore, to facilitate a more detailed and site‐specific environmental risk assessment in the marine area, an application‐based exposure scenario must be developed. Until these data and tools become available, environmental hazard and risk assessments may be carried out using existing data from freshwater organisms and existing tonnage‐based exposure scenarios as a potential surrogate.

“…It is important to mention that the presence of UV filters in marine mammals raised the concern and supports the hypothesis of bioaccumulation and biomagnification of the UV filters through the food chain. Recently, Pawlowski et al presented a tool (EcoSun Pass) that allows the evaluation of the eco-friendly profile of UV filters contained in photoprotective cosmetic formulations, especially sunscreen products [ 97 ], which could help avoiding the environmental hazard of future chemical substances, especially UV filters.…”

UV Filters: Challenges and Prospects

The use of sunscreens is an established and recommended practice to protect skin from solar-induced damage. Around 30 UV filters can be used in sunscreen products in the European Union, which ought to follow the requirements of the regulation 1223/2009 to ensure their efficacy and safety for humans. Nevertheless, low photostability and putative toxicity for humans and environment have been reported for some UV filters. Particularly, the negative impact in marine organisms has recently raised concern on the scientific community. Therefore, it is important to develop new UV filters with improved safety profile and photostability. Over the last two decades, nearly 200 new compounds have revealed promising photoprotection properties. The explored compounds were obtained through different approaches, including exploration of natural sources, synthetic pathways, and nanotechnology. Almost 50 natural products and around 140 synthetic derivatives, such as benzimidazoles, benzotriazoles, hydroxycinnamic acids, xanthones, triazines, among others, have been studied aiming the discovery of novel, effective, and safer future photoprotective agents. Herein, we provide the reader with an overview about UV filters’ challenges and prospects, offering a forward-looking to the next-generation of UV filters.

“…Sunscreens play a strategic role in the prevention of photo-induced damage. In recent years, the demand for high-quality solar products that combine high efficacy with excellent sensory properties, but are also environmentally friendly, has increased [ 1 ]. In particular, the impact of solar products on marine ecosystems with the possibility of bioaccumulation of organic filters and consequent toxicity towards the coral reef has received attention [ 2 , 3 , 4 ].…”

“…Among these, the use of natural photoprotectors in association with UV filters in solar products has been proposed for an increase in solar protection factor (SPF) combined with an antioxidant activity, which therefore allows reduction in the amount of chemical filters in solar formulations [ 5 ]. Moreover, the formulation also has a role, as the different excipients employed contribute to some ecotoxicological hazards [ 1 ].…”

“…In the present work, pollen from L. clavatum has been investigated as a delivery system for the organic solar filter ethylhexyl triazone (ETZ, Uvinul ® T150), which is authorized for use in Europe up to a 5% concentration (Annex VI, Regulation (EC) No. 1223/2009) and is considered environmentally friendly [ 1 ] and reef-safe [ 23 ]. A particularly interesting property is its high molecular weight (823.07 g mol −1 ), which impairs skin penetration.…”

Sporopollenin Microcapsule: Sunscreen Delivery System with Photoprotective Properties

In recent years, the demand for high-quality solar products that combine high efficacy with environmentally friendly characteristics has increased. Among the coral-safe sunscreens, ethylhexyl triazone (Uvinul® T150) is an effective organic UVB filter, photostable and practically insoluble in water, therefore difficult to be formulated in water-based products. Oil-free sunscreens are considered ideal for most skin types, as they are not comedogenic and do not leave the skin feeling greasy. Recent studies reported that pollen grains might represent innovative drug delivery systems for their ability to encapsulate and release active ingredients in a controlled manner. Before being used, the pollen grains must be treated to remove cellular material and biomolecules, which could cause allergic reactions in predisposed subjects; the obtained hollow structures possess uniform diameter and a rigid wall with openings that allow them to be filled with bioactive substances. In the present work, pollen from Lycopodium clavatum has been investigated both as a delivery system for ethylhexyl triazone and as an active ingredient by evaluating its photoprotective capacity. The goal is to obtain environmentally friendly solar aqueous formulations that take advantage of both sunscreen and sporopollenin microcapsules’ UV protection with a relatively low cost, as these pollen grains are widely available.
