TH11980C3 - Bio-nano-composite of chitosan and cellulose derivatives. From pineapple peel - Google Patents

Abstract

Invention Conclusion 17/03/2016 The nano-composite of carboxymethyl cellulose from pineapple rind can be prepared using chitosan derivatives. Carboxymethyl cellulose, cellulose derivatives, and cosmetic active substances through a process of mixing at the appropriate temperature and time and using ferrulic acid as a binder. (cross-linker) where, for the nano-composite, can be used as a carrier Important substances in cosmetics and drugs that are safe to use. Does not destroy the ecology and reduce their impact on the environment. -------------------------------------------------- - New request, revised 9/08/2016 The nanocomposite of carboxymethyl cellulose from pineapple peel can be prepared using chitosan derivatives.
