Cosmetics, a captivating category of over-the-counter products that enhance appearance and promote skin health, have become ubiquitous in modern society. Initially associated with altering one’s appearance, cosmetics have evolved beyond their traditional beauty role to encompass skincare and the treatment of various skin conditions. While numerous chemicals can be utilised in cosmetic formulations, key ingredients include water, emollients, humectants, surfactants, preservatives, antioxidants and ultraviolet (UV) filters. With the rise in consumer preferences for clean beauty, silicone- and paraben-free cosmetics and cruelty-free testing, safe and effective herbal and plant-based products have gained significance. Researchers are actively exploring the development of natural cosmetics, leveraging the synergistic properties of these substances. Nanoformulations such as liposomes, nanoparticles and emulsions have been investigated and proven safer and more efficient than conventional cosmetics. This chapter provides a comprehensive overview of the utilisation of these ingredients in cosmetics, their specific effects on product development and properties, emerging alternatives in the personal care market, the widespread adoption of nanotechnology in various scientific fields, and its impact on the advancement of personal care products.

“…Unfortunately, the lack of treatment or inappropriate treatment of industrial wastewater has been a source of pollution of groundwater, lakes, and rivers [9,10]. For example, eutrophication is one of the problems associated with the discharge of nutrients (especially nitrogen and phosphorus) and organic matter into the receiving watercourse, which leads to a marked oxygen depletion due to bacterial decomposition of organic matter and high turbidity, with severe consequences for the natural fauna and flora [11,12].…”

The transition from the linear economy paradigm to the circular economy in industrial wastewater treatment systems is on the global agenda. The search for new simple, eco-innovative, and low-cost processes for treating industrial wastewater, which can also be used by small and medium-sized industries, has been a constant challenge especially when environmental sustainability is considered. So, a new integrated industrial wastewater treatment system has been developed that includes the immediate one-step lime precipitation process (IOSLM) and atmospheric carbonation (AC), followed by constructed wetlands (CWs) or adsorption. The current review provides an overview of industrial wastewater treatment strategies for high- and low-biodegradable wastewater. A background on functionality, applicability, advantages and disadvantages, operating variables, removal mechanisms, main challenges, and recent advances are carried out for each process that makes up the IOSLM+AC+CW/adsorption integrated system. The prospects of the IOSLM+AC+CW/adsorption integrated system are also discussed. Not neglecting the improvements that still need to be made in the integrated treatment system as well as its application to various types of industrial wastewater, this review highlights that this treatment system is promising in industrial wastewater treatment and consequent by-product recovery. The IOSLM+AC integrated system showed that it can remove high amounts of organic matter, total suspended solids, oils and fats, phosphorus, and ammonium nitrogen from industrial effluents. On the other hand, constructed wetlands/adsorption can be alternatives for refining effluents still containing organic matter and nitrogen that were not possible to remove in the previous steps.

“…The use of natural polysaccharide biopolymers has raised significant interest due to their efficiency, abundance, biodegradability and specific biocompatibility (Bibi et al, 2019; Graham et al, 2019). In this context, polysaccharide-based hydrogels have been pointed out as an exceptional class of biomaterials which has attracted great interest in treating wastewater due to their eco-friendliness, low cost and efficient interactions with water contaminants (Mokeddem et al, 2023; Singh et al, 2021). Indeed, hydrogels are three-dimensional cross-linked polymer networks with a high capacity to absorb water and biological fluids (El Sayed, 2023).…”

Facile synthesis of double-cross-linked alginate-based hydrogel: Characterization and use in a context of circular economy for cationic dye removal

et al. 2023

Hydrogels based on natural polysaccharides have received special attention in the last decade due to their interesting features, such as availability, biocompatibility, biodegradability and safety. Such characteristics may make them sustainable and eco-friendly materials for water and wastewater treatment, meeting the concept of circular economy. In this study, a novel double-cross-linked alginate-based hydrogel has been successfully synthesized using epichlorhydrin and sodium trimetaphosphate (STMP) as cross-linker agents and then used for the removal of methylene blue (MB) dye under different operating conditions. The obtained hydrogel was deeply characterized by using various analytical techniques, namely Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy and differential scanning calorimetry. Experimental results showed that the synthesized double cross-linked hydrogel with relatively high STMP concentration (0.26 M) has promising structural and textural properties. This material exhibited excellent removal ability towards MB with a maximum adsorption capacity of about 992 mg/g for an initial pH of 10. The kinetic and isotherm modeling study revealed that the pseudo-second-order and Freundlich models fitted well the measured adsorption experimental data. The MB adsorption process onto the synthesized hydrogel is exothermic, feasible and spontaneous. It mainly includes electrostatic interaction and hydrogen bonds. These findings suggest that double-cross-linked alginate-based hydrogel can be considered as an attractive and potential adsorbent for an effective cationic dye removal from aqueous environments. The use of such a green adsorbent for the treatment of organic-pollutants-rich industrial wastewaters promotes sustainability and circular economy concepts.
