Development of Films for Suppression of Halitosis and Oral Antimicrobial from CMC in Durian Peel

Carboxymethyl cellulose or CMC is a natural substance which can used for personal care products. CMC can be used as forming agent in the preparation of water-soluble film or as an edible film. Thus, this project was aimed to synthesize CMC for edible film production from cellulose that obtained from durian peel. Then, all herbs that known as halitosis treatment such as mint leaves, cloves, Indian marsh, sappan and guava leaves were added for oral antimicrobial investigation. The chemical structure of the cellulose and CMC were then characterized using FTIR. The physical and microbiological properties of the film were evaluated. For physical properties study found that the CMC obtained was relatively scentless, smoothness, slightly turbid, transparent and viscous. Additionally, results showed that CMC ratio was affects the physical characteristics of the film, the high CMC ratio gave the greater film tensile strength, weight and thickness. There were 3 formulas of edible film using CMC as film forming agent were carried out. Results found that 8% CMC, 14% of glycerin given good properties of the film. The films antimicrobial testing by agar diffusion test using C.albicanswas conducted. The results showed partial inhibition zone threatening film of the mint, clove and Indian march, while there no inhibition zone from film that add with guava leaf and sappan including control film. This may be due to the low concentration of the herbal soak used in the film. Thus, higher herbal concentration or essential oil of herb should be concern for further study.
