Increasing use of nano materials and the need to find new sources to produce nanofibrils have led many researchers for preparing and characterizing nano cellulose from agricultural sources. Accordingly, the objectives of this study are preparation and characterization of nanofibrils of cellulose from heart-of-peach palm residue. This paper presents the preparation of nanofibrils from heart-of-peach palm residue by mechanical fibrillation of bleached cellulose pulp. Characterization includes their dimensions, chemical constituents and toxicity. The nanofibrils produced in gel form contained about 97.8g/100g of moisture and 2.2 g/100g of total fiber content. No toxicity was observed to the brine shrimp Artemia salina up to 50 g/L of fibrils indicating they are not toxic to such an animal. It is hoped these results will encourage the search for other nano-structured materials that is non-toxic to the environment.
