Abstract

Water and cooking oil are fluids that we often encounter in our daily lives and are often needed. Water is polar while cooking oil is non-polar, so in uniting the two fluids an emulsifier (Tween 20) is used to mix them. The aim of this research is to combine polar and non-polar fluids. Emulsifier (Tween 20) is used as a polysorbate surfactant (mixing agent) for the two fluids and can mix perfectly. The combined water and oil are mixed using a mixing stirrer with a speed of 100-200 rpm, a temperature of 70⁰C, within 1 hour. To obtain a fluid density value by providing heating from 30⁰C-90⁰C, then inserting it into a 25 ml volumetric flask and weighing it. After mixing, a white hybrid fluid will be produced, and it will separate again when the fluid is at room temperature.

Abstract

Water-based cooling systems can promote corrosion of metal components, while conventional ethylene glycol coolants pose toxicity and environmental concerns. To address these issues, a novel coolant derived from crude palm oil (CPO) was evaluated for its corrosion behavior on SPCC-based electro-galvanized steel, a material commonly used in radiator applications. The coolant formulation consisted of glycerol, propylene glycol, a CPO-based component, and distilled water, blended to achieve a homogeneous mixture, with chemical analysis confirming three principal natural constituents accounting for nearly the entire formulation. Corrosion performance was assessed by static immersion of SECC samples in the CPO-derived coolant at ambient temperature for 336 h. No measurable weight loss was detected after immersion. SEM–EDS analysis revealed a predominantly zinc-rich surface with no evidence of Fe-rich oxide formation, while XRD patterns were dominated by metallic Zn and Fe reflections at 2θ ≈ 44.6°, 65.2°, and 82.38°, with no diffraction peaks corresponding to crystalline iron corrosion products such as hematite, magnetite, or goethite. The absence of corrosion-related diffraction features and rust formation indicates that the CPO-based coolant did not induce corrosion under the investigated short-term conditions. These results suggest that the CPO-derived coolant is a promising renewable and corrosion-compatible alternative for cooling applications, although further evaluation under long-term, dynamic, and elevated-temperature conditions is required.
