Surfactants are substances that when in aquatic environments can cause negative impacts. Hospital effluents carry numerous chemicals daily, including surfactants, used in sanitization and disinfection procedures. These chemicals are found in the effluents and reach water bodies due to a lack of proper removal in the wastewater treatment plants. The present study investigated data about wastewater monitored from healthcare facilities located in the city of Belo Horizonte, Brazil, focusing on anionic surfactants. The results showed 72 establishments monitoring this parameter, resulting in a median concentration of 1 mg L and 2.49 mg L mean value of anionic surfactants, between 2007 and 2019. It is also observed in the correlation between surfactants and oils in all healthcare establishment sizes, except for the medium-sized. Although anionic surfactants are the most used in cleaning product formulations, cationic surfactants still do not have specific legislation in the studied country that dictates a limit for discharge into sewage; consequently, they are not routinely monitored in effluents. However, these compounds are used in the formulation of routine hospital products.

Sulfate and sulfonate compounds are extensively used as anionic surfactants in personal care products (PCPs), which might pose adverse potential to human health. However, available research mostly identified certain subsets of sulfated and sulfonated surfactants based on target analysis. In this study, we developed a comprehensive nontarget strategy for identification of sulfated and sulfonated surfactants in PCPs using UHPLCHRMS supplemented by an in-lab R script based on characteristic fragment ions and sulfur isotope patterns.

This study examines the adsorption and bulk assembly behaviour of quaternized hydroxyethylcellulose ethoxylate (QHECE)-sodium dodecyl sulphate (SDS) complexes on negatively charged substrates. Due to its quaternized structure, QHECE, which is used in several industries, including cosmetics, exhibits enhanced electrostatic interactions. The phase behaviour and adsorption mechanisms of QHECE-SDS complexes are investigated using model substrates that mimic the wettability and surface charge of damaged hair fibres.

Surfactants play a crucial role in various industrial applications, including detergents and personal care products. However, their widespread use raises concerns due to their potential environmental impact and health risks, particularly in aquatic ecosystems, where they can disrupt the balance of marine life and accumulate in water sources, posing challenges to sustainable development. This study investigates the environmental and health implications of anionic and nonionic surfactants, focusing on their toxicity, biodegradation, and skin irritation potential profiles, especially when combined with silica nanoparticles.

Water-in-oil high internal phase emulsions (W/O-HIPEs) typically rely on large amounts of surfactants to disperse water droplets and usually use crystalline saturated triacylglycerides (TAGs) to enhance processing properties. However, these practices conflict with consumer demands for 'natural' ingredients. This study seeks to develop novel crystal fractions similar to saturated TAGs for the preparation of W/O-HIPEs as low-calorie fat mimetics, focusing on their mechanical and mouthfeel properties, which have received little attention thus far.

Aqueous film-forming foam (AFFF) is a targeted product for liquid fuel fires and has the benefits of a long storage period and high fire extinguishing efficiency. However, because of the toxicity and bioaccumulation of the core raw material's long-chain fluorocarbon surfactant, traditional AFFF is being phased out. For this reason, three efficient AFFFs (F-1, F-2, and F-3; more details in Table 2) were designed using anionic surfactants (PBAF) with branched C perfluorinated chains, hexadecyltrimethylammonium bromide (CTAB), and dodecyl dimethyl betaine (BS-12) as core materials.
