Micro/nanocellulose from waste Pili (Canarium ovatum) pulp as a potential anti ageing ingredient for cosmetic formulations
Abstract The potential of nanocellulose synthesized from waste pili pulp to replace mineral based ingredients in cosmetics has been determined. Waste Pili pulp is biomass that comes from the extraction process, in the production of Pili essential oils. Conventional methods of cellulose extraction: boiling, alkalization and bleaching methods were employed to isolate cellulose from lignocellulosic and hemicellulosic materials. Sulfuric acid hydrolysis at 64 wt has been used to synthesize nanocellulose at varying reaction times (30, 45 and 60 minutes) Infrared spectrum of the isolated cellulose has an 85% match with a cellulose. The conditions for acid hydrolysis produced micro sized cellulose with an average particle size of 3.4x105 nm or 34 um and exhibited broad particle size distribution due to rapid agglomeration of some of its particles. Surface morphology analysis showed the nanostructures of the synthesized micro/nanocellulose at different time regimes. The optical properties of the cellulose suspensions were found almost parallel to that of the conventional mineral based nanoparticles used in cosmetics; verifying nanocellulose as a promising alternative to mineral based ingredients for cosmetics
