This study focused on the development and evaluation of two phenyl formulations, Formula-I (F-I) and Formula-II (F-II), to assess their physical, chemical, and antimicrobial properties. Conducted during 2015-16 in Dharwad, Karnataka, the research aimed to formulate effective, safe, and environmentally friendly disinfectant solutions. The formulations included Turkey Red Oil and Pine Oil (F-I) and Lethol with Pine Oil (F-II), with color added to enhance visual appeal.

Quality analysis revealed that both formulations maintained a pH range of 6.5-7.2, indicating a neutral to slightly alkaline nature suitable for safe cleaning. They were soluble in water and organic solvents, stable for up to three months, and unaffected by hard water conditions. Additionally, both formulations showed no presence of alcohol-insoluble matter, indicating high purity.

Antimicrobial assessments demonstrated strong efficacy against common pathogens. Both F-I and F-II exhibited significant antibacterial activity against Staphylococcus aureus and Escherichia coli, with F-I showing a lower Minimum Inhibitory Concentration (MIC) of 1.56 µL for S. aureus, indicating higher potency. F-II displayed an MIC of 6.25 µL for E. coli, confirming its effectiveness.

The results highlight the potential of these phenyl formulations as reliable disinfectants for household, industrial, and healthcare settings. Both formulations showcased optimal disinfectant properties, combining safety, stability, and environmental compatibility. The findings contribute to the development of sustainable cleaning solutions, offering insights for future research on eco-friendly disinfectants and alternative green ingredients for broader applications.
