• The mucilage, originating from the seeds of quince fruit was characterized as a potential bio-inspired water-based lubricant. The mucilage consists mainly of fine cellulose nanofibrils and charged hemicelluloses whose structure and properties were characterized here by atomic force microscopy (AFM) and tribological Pin-On-Disc (POD) experiments. The hemicellulose-decorated nanocellulose fibrils were 3.0±0.7nm in thickness, had a very large aspect ratio and also had a tendency to self-align when dried on mica surface. Macroscale tribological tests showed that the mucilage was able to reduce the coefficient of friction of polyethylene/stainless steel contact to values below 0.03. Thus, we show that quince mucilage is a native nanocellulose material with a notable ability to lower friction. [Display omitted] •We characterize a mucilage extracted from seeds of a quince fruit.•We show that the mucilage lubricates PE/stainless steel contact better than water.•Promising tribological behavior of quince mucilage has not been presented before.•Quince mucilage inspires search for other high-performance water-based lubricants.
