The invention relates to the technical field of fabric softeners, in particular to a bio-based color fixing softener as well as a preparation method and application thereof. The bio-based color fixing softener comprises a bio-based component modified organic silicon polymer, the bio-based component modified organic silicon polymer has a brush type and/or branched chain molecular structure, and the preparation raw materials of the bio-based component modified organic silicon polymer comprise double-end epoxy silicone oil, catechol functional chitosan and chlorosiloxane; the catechol functionalized chitosan is 3, 4-dihydroxy phenylpropionic acid conjugated chitosan. Chitosan is modified, so that a large number of side chain structures containing amino, hydroxyl and other active groups are formed in a chitosan molecular structure, on one hand, a large number of reaction active sites and functional sites are formed, and meanwhile, the acting force between polymer molecules and a coloring agent and the like can be
