“…The choice of a nylon membrane as a supporting membrane is due to its stable structure in both acidic and alkaline conditions (Supplementary Fig. 2 and 3 ) 33 – 35 . Meanwhile, the nylon membrane possesses a large pore size of 0.2 μm, which will not influence the permeance of the FBN membranes.…”

Pressure-driven, superfast organic solvent filtration membranes have significant practical applications. An excellent filtration membrane should exhibit high selectivity and permeation in aqueous and organic solvents to meet increasing industrial demand. Here, we report an amino functionalized boron nitride (FBN) based filtration membrane with a nanochannel network for molecular separation and permeation. This membrane is highly stable in water and in several organic solvents and shows high transport performance for solvents depending on the membranes’ thickness. In addition, the FBN membrane is applicable for solute screening in water as well as in organic solvents. More importantly, the FBN membranes are very stable in acidic, alkaline and oxidative media for up to one month. The fast-flow rate and good separation performance of the FBN membranes can be attributed to their stable networks of nanochannels and thin laminar structure, which provide the membranes with beneficial properties for practical separation and purification processes.

“…Ether alcohols, such as chlorphenesin, 2-phenoxyethanol, benzyl alcohol, pentanediol, hexanediol, and octanediol, recognized as gentler preservative alternatives, also offer broad-spectrum antibacterial benefits [27][28][29]. Organic acids and their salts, containing levulinic acid, anisic acid, sorbic acid/potassium sorbate, and benzoic acid/sodium benzoate, although less effective against bacteria, inhibit fungi and are often used in combination with other substances like hydantoin for enhanced preservation [30,31]. Ether alcohols, such as chlorphenesin, 2-phenoxyethanol, benzyl alcohol, pentanediol, hexanediol, and octanediol, recognized as gentler preservative alternatives, also offer broad-spectrum antibacterial benefits [27][28][29].…”

Despite advancements in analytical technologies, the complex nature of cosmetic matrices, coupled with the presence of diverse and trace unauthorized additives, hinders the application of these technologies in cosmetics analysis. This not only impedes effective regulation of cosmetics but also leads to the continual infiltration of illegal products into the market, posing serious health risks to consumers. The establishment of cosmetic regulations is often based on extensive scientific experiments, resulting in a certain degree of latency. Therefore, timely advancement in laboratory research is crucial to ensure the timely update and adaptability of regulations. A comprehensive understanding of the composition of cosmetic matrices and their pretreatment technologies is vital for enhancing the efficiency and accuracy of cosmetic detection. Drawing upon the China National Medical Products Administration’s 2021 Cosmetic Classification Rules and Classification Catalogue, we streamline the wide array of cosmetics into four principal categories based on the following compositions: emulsified, liquid, powdered, and wax-based cosmetics. In this review, the characteristics, compositional elements, and physicochemical properties inherent to each category, as well as an extensive overview of the evolution of pretreatment methods for different categories, will be explored. Our objective is to provide a clear and comprehensive guide, equipping researchers with profound insights into the core compositions and pretreatment methods of cosmetics, which will in turn advance cosmetic analysis and improve detection and regulatory approaches in the industry.

“…Benzoic acids have garnered considerable interest in the fields of food and drug production [29] ; however, it has been reported that benzoic acids cannot be separated on a bare ZrO 2 column. A possible reason for this is that the benzoic acids could be strongly adsorbed by the Lewis acid sites on the ZrO 2 materials [30] .…”
