“…to reduce the surface tension of liquids. They also cause different surface activities, such as foamability, adsorption, wetting, and the ability to aggregate, disperse, or emulsify [1]. Because conventional surfactants lose their activity under specific conditions and to increase the range of available and compatible products, research into developing numerous functional surfactants, such as silicone (DMS)-based [2,3], gemini-based [4][5][6], and polymer-based surfactants [7], has increased in recent years.…”

The present work reports the application of trisiloxane polyether silicone surfactant to remove various stains along with a range of hydrocarbon (organic) surfactants to investigate whether silicone surfactants offer synergism or antagonism during the cotton fabric cleaning process. Cotton fabric was soiled with red wine, turmeric, permanent marker, acrylic paint, and coffee and washed with the original fabric in aqueous solutions of individual surfactant and blend of surfactants by applying the conventional shaking washing method. The detergency and soil redeposition were determined from the alteration in the surface reflectance of prepared stained fabrics and the original fabric after washing. Surfactants used for the washing were trisiloxane polyether silicone surfactant (AG-Platinum), sodium dodecyl benzene sulfonate, lauryl alcohol ethoxylate (LA-10), and nonylphenol ethoxylate (NP-10) and their blends. In comparison with individual hydrocarbon surfactants, blends of surfactants (with different hydrocarbon to silicone surfactant ratios) dislodged stains (accumulated on the fabric as a result of staining) effectively at shorter time and at lower bath ratio because of superior surface properties. With increasing concentration of surfactant, detergency increased and reached a maximum at the critical micelle concentration (CMC). Silicone surfactant reduced the CMCs of the surfactant blends and provided better detergency at lower concentration. From this study, it was found that silicone surfactant could be successfully introduced into laundry detergent formulations. Graphical abstract

“…The phenomenon of liquid spreading on a solid (or liquid) surface is called wetting, resulting from intermolecular interactions when the two are brought together . In order to clearly reflect the wettability of FAQAS‐containing plating baths on the copper surface, drop shape analysis system was utilized to measure the contact angle of it, with basic electrolyte as a comparison.…”

A series of fatty acid quaternary ammonium surfactants (FAQAS 1 a–1 f) derived from renewable resource of fatty acid have been rationally designed and investigated as levelers applied in copper electroplating. Surface tension and contact angle indicated the FAQAS's surfactivity and wettability were closely related to the length of hydrophobic chains. FAQAS 1 a–1 f displayed the capability to inhibit the copper deposition in CV tests and their inhibiting abilities agreed with the order of their surfactivity and wettability. Compound 1 e showed the best inhibition capability, and was comprehensively tested by field‐emission scanning electron microscopy (FE‐SEM), X‐ray photoelectron spectroscopy (XPS) and other electrochemical measurements. The strong inhibition ability of compound 1 e on copper electrodeposition could be attributed to its fast and strong absorption of 1 e on the cathode surface. Moreover, galvanostatic measurements (GMs) indicated that compound 1 e not only cause polarization but also has stable synergistic effects with other additives to form a convection dependent competitive adsorption layer. In addition, through‐hole (TH) electroplating experiments verified that uniform TH could be obtained on copper electrodeposition using the bath containing compound 1 e. This work may shed some light on the pratical application of surfactants as effective leveler in acid copper electroplating.

“…The methodology of emulsification is also one of the vital factors to procure the smallest droplet size of the emulsion. Many researchers have focused on identifying suitable methods for emulsification which are efficient, competitive and effective [3,7]. Acoustic cavitation using ultrasound is one of the methods which could be employed for emulsification.…”

In the present study, Nanoemulsions of neem oil and pine oil using a binary surfactant system were prepared and tested their antibacterial properties. A polysorbate-type nonionic surfactant and alcohol ethoxylatesurfactant (Galaxy MW-259) were used in different proportions to obtain stable nanoemulsions at the lowest possible droplet size. The emulsification process variables such as ratio of alcohol ethoxylatesurfactant to polysorbate-type nonionic surfactant, surfactant concentration, ratio of Neem oil to pine oil, oil weight fraction and sonication time were studied. The optimal variables include the ratio of alcohol ethoxylatesurfactant to polysorbate-type non-ionic surfactant of 80:20, surfactant concentration of 4%, ratio of Neem oil to pine oil of 80:20, oil weight fraction of 20% and 20 min of sonication time at 40% of the applied power. Nano-emulsions were found to be very stable with emulsion droplet size around 25-30 nm. The traditional method and probe sonicator methods are used for the preparation of oil in water Nano-emulsion of Neem oil, pine oil, a non-ionic binary surfactant system is used as an emulsifier. This newly developed nanoemulsion provides better antimicrobial, anti-bacterial and anti-mosquito repellent properties into the treated fabrics.
