Abstract:
Sodium carboxymethyl chitosan (SCM-chitosan) was prepared by O-carboxymethylation
reaction with monochloroacetic acid and use as a novel fixative for eau de cologne. SCMchitosan
is soluble in water but insoluble in ethyl alcohol, the optimum volume ratio between
water and alcohol that still be able to soluble 0.1 percent of SCM-chitosan is 2:3. Water solubility
of perfume compounds in eau de cologne affected the solubility of SCM-chitosan. The more
water solubility of perfume compounds, the higher solubility of SCM-chitosan in formulation.
Headspace analysis using gas chromatography is the method for evaluate fixative effect. SCMchitosan
has the significant fixative effect on p-cresyl methyl ether at concentration 10%in DPG
eau de colonge. The fixative efficiency can rise to 92.19 percent at the temperature of 53 oC.
However the fixative effect of SCM-chitosan on benzyl alcohol eau de colonge, ethyl acetoacetate
eau de colonge and 94085 floral-fruity eau de cologne needs to future investigation due to the
precipitation of the systems which might be cause by incompatibility between SCM-chitosan and
the aroma material.
