Review on Silicone Surfactants: Silicone-based Gemini Surfactants, Physicochemical Properties and Applications

Abstract

The increasing use of silicone polymers has attracted the interest of many researchers and manufacturers for the past three decades. The silicone surfactants have excellent surface properties, of which the wetting and spreading ability is particularly noteworthy. So silicone surfactants are used in various fields, starting with textiles to agriculture. Because of this particular wetting and spreading property, silicone surfactants will be used together with conventional surfactants to achieve the desired throughput. In this paper we describe in detail the origin of silicone surfactants and various silicone surfactant compounds, as well as their physicochemical properties. We also handle various applications of silicone surfactants in agriculture, textile manufacturing, personal care and cosmetics, polyurethane foam, metal extraction, foam floatation and other industrial applications. However, the main focus is on the latest syntheses, developments and applications of newly developed tailor-made molecules.

Exploring an Innovative Strategy for Suppressing Bacterial Plant Disease: Excavated Novel Isopropanolamine-Tailored Pterostilbene Derivatives as Potential Antibiofilm Agents

“…The bioactivities of compound C 1 were superior to those of commercial BT (33.3% for curative activity and 35.4% for protective activity) and TC (30.6% for curative activity and 32.5% for protective activity). Moreover, blending pesticide additives often provides better bioactivity than using raw pesticides because these auxiliaries could enhance their bioactivity as well as the surface wettability and permeability. , Notably, when 0.1% (v/v) of organic silicone ( OSi ), organic fluorine ( OF ), and orange peel essential oil ( OPO ) were combined with compound C 1 , the resulting antibacterial activity increased substantially. For example, the addition of OSi to compound C 1 treatment significantly enhanced their bioactivity against Xoo with curative and protective activities of up to 59.5 and 56.9%, respectively.…”

Thermodynamic Analysis of Trisiloxane Surfactant Adsorption and Aggregation Processes

“…Modified siloxanes composed of the hydrophobic and hydrophilic moieties within the same molecule (amphiphilic nature) reduce the surface tension and exhibit a tendency to association and self-assembly. Thus they can be applied as surfactants [24][25][26]. Siloxane surfactants consist of a methylated siloxane hydrophobic group coupled to one or more polar groups.…”

Natural Products-Based Botanical Bactericides Discovery: Novel Abietic Acid Derivatives as Anti-Virulence Agents for Plant Disease Management

“…Its protective and curative activities were significantly higher than those of commercial TC (40.8 and 43.6%, respectively). Studies indicate that particular additives can improve the surface wettability and permeability of pesticides, , potentially improving the bioactivity of compound C 2 alone. Indeed, antibacterial efficacy was improved significantly following treatment with compound C 2 in combination with organic silicone (OSi, 0.1%, v/v) and orange peel essential oil (OPO, 0.1%, v/v).…”
