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.  aChemical composition  aToxicity  aArtêmia Salina  aBleached pulp  aBrine shrimp  aHeart-of-Peach Palm Residue  aMechanical fibrillation  aNanostructure1 aMAGALHAES, W.
