Natural surfactants are surface-active molecules synthesized from renewable resources (i.e., plants, animals, or microorganisms) and possess properties comparable to conventional surfactants, making them an environmentally friendly potential alternative petrochemical surfactants. Additionally, they exhibit biological such as anti-microbial properties, biodegradability, less toxicity, allowing their use in everyday products with minimal risk human health the environment. Based on mode of production, natural can be classified into first-generation bio-based second-generation biosurfactants, although definition may vary depending author literature. This review offers extensive classification focusing composition, sources, production methods, applications across various industries. Furthermore, main challenges future perspectives discussed.

Abstract The utilization of sustainable feedstocks in surfactant production is crucial for reducing environmental impact, enhancing resource efficiency, and aligning with global efforts toward a circular economy green chemistry. In this research, cellulose derivatives were synthesized by methylating fibers extracted from Guinea grass ( Megathyrsus maximus ) their interfacial properties as surfactants evaluated. characterized using Fourier‐transform infrared spectroscopy (FTIR), which revealed distinct stretching vibration absorption bands indicative methyl groups. Thermogravimetric analysis (TGA) identified dual‐stage decomposition process, consistent reported behavior methylcellulose. Time‐of‐flight secondary ion mass spectrometry (TOF‐SIMS) further confirmed the presence ether groups, H 5 CO + detected characteristic fragment methylated samples. Functional evaluations demonstrated that double‐methylated exhibited hydrophilic–lipophilic balance (HLB) 12.7 surface tension 55 dyne/cm when compared to mono or unmethylated fibers. Additionally, displayed enhanced foaming activity, emulsion stability, water solubility. These cellulose‐based comparable synthetic counterparts, emphasizing potential industrial applications role advancing material development.
