Development of Aromatherapy Massage Oil Formulation from Cinnamomum Sintoc Essential Oil

Cinnamomum essential oils are extensively used in aromatherapy for their natural scent and therapeutic benefits. This study aimed to develop aromatherapy massage oil containing C. sintoc oils and evaluate users' satisfaction. C. sintoc essential oil was extracted by hydrodistillation method and characterized using a GC-MS. Preference tests of four essential oil mixtures, six carrier oil formulations, and C. sintoc massage essential oil formulation were determined in seventy healthy volunteers. Physical and chemical stability evaluation of C. sintoc massage essential oil was investigated over a storage period of up to 12 months. The major chemical compositions of C. sintoc essential oils were 1,8-Cineole, α-Terpineol, Cymene, Terpinen-4-ol, and Linalool. In odor preference test, the volunteers rated EOM2 (Lemongrass oil, C. sintoc oil, and Patchouli oil) with the highest satisfaction score, while carrier oil preference test, COF1 (Coconut and Palm kernel) was significantly preferred to the color, odor, and spreadability on the skin (p ≤ 0.05). In essential massage oil formulations preference test, MEO1 (C. sintoc massage oil) was rated significantly higher than MEO2 (Zingiber cassumunar massage oil) in terms of physical appearance (odor, viscosity), usability (distribution, slipperiness, absorption), emotion (refresh, relax, dynamic, romantic, and calm), and overall preference (p ≤ 0.05). Moreover, physical and chemical stability evaluation of C. sintoc massage oil was stable during 12 months of storage. The findings indicated that C. sintoc massage oil demonstrated overall preference in terms of physical appearance, usage, emotional response, and long-term storage stability.
