The effect of chitosan concentration on the properties of dermatological preparations prepared with 2% methylcellulose and 10% polyvinylpyrrolidone was studied. As the levels of chitosan, propylene glycol-1,2 and glycerol increased, the hardness, consistency and cohesiveness of the hydrophilic gels increased, while the dissipation capacity decreased. Gels based on methylcellulose and chitosan, compared...
The aim of the study was to evaluate the effect of methylcellulose and carboxymethylcellulose on the rheological properties of hydrogels applied to skin on chitosan in the presence of the additives propylene glycol and glycerol. Rheological studies showed that the tested gels are non-newtonian systems, and have thixotropic properties. Substrates made of methylcellulose and chitosan are characterised...
