Formulation and Physicochemical Characterization of Terpenocannabinoid-Functionalized Hemp Oil Emulsifier: Assessment of Topical Anti-Inflammatory, Antinociceptive, Wound Healing Activity and Cutaneous Toxicity Effects

Abstract

This article presents a comprehensive study on the formulation and physicochemical characterization of a novel terpenocannabinoid-functionalized hemp oil emulsifier (AMCana-Oil) for potential applications in topical anti-inflammatory, antinociceptive, and wound healing treatments. The emulsifier exhibits interesting properties, meets international acidity index requirements, and has a room temperature density comparable to liquid oils. The prepared emulsifier (AMCana-Oil), AMCana-Oil (10% TC) and AMCana-Oil (20% TC), contains a diverse array of cannabinoids, including cannabidiol (CBD) and delta-9-tetrahydrocannabinol (THC), alongside bioactive compounds such as benzenepropanoic acid and oleamide. Physicochemical properties of AMCana-Oil and MCana-Oil (20% TC) were found, respectively, as follows: density value of 0.9872 ± 0.001 mg/mL: g/cm³ and 0.9882 ± 0.002 mg/mL: g/cm³; an acidity index of 1.599 ± 0.002 mgKOH/g and 1.605 ± 0.001 mgKOH/g; an average peroxide value encompassing a range from 12.982 ± 0.351 to 23.320 ± 0.681 (mEq O2/kg), and a K of 1.575 ± 0.004 and 1.535 ± 0.0039, which underscore the fluidity, stability, and quality of emulsifiers studied. Preliminary pharmacological examinations reveal significant antioxidant, anti-inflammatory, antinociceptive, and wound healing potentials. Moreover, in silico predictions confirm the safety profile of the prepared emulsifiers. These findings emphasize the multifaceted nature of the terpenocannabinoid-functionalized emulsifier, paving the way for its potential applications in topical formulations.
