The aim of this work is to evaluate the stability and release of chitosan beads loaded with
volatile molecules of Mentha piperita essential oil (EO) in a cosmetic formulation. The ability
of the beads to quickly release Mentha piperita EO during use of a cosmetic formulation
such as a bath foam is also assessed. The chitosan beads were produced with three
different chitosan dispersions gelled with two different gelling solutions:(a) a 10% solution of
sodium hydroxide (NaOH) and (b) a 4% solution of sodium tripolyphosphate (TPP). A few …
