Abstract
Cosmetics, toiletry and household cleaning products are often based on different types of polymeric gels with specific rheological
behavior. Dynamic shear oscillation measurements were used for the monitoring of in situ polymerization process, and to
determine the viscoelastic properties of the hydrogels based on polyacrylamide and acetone-formaldehyde resin. Both storage
modulus G’ and loss modulus G” were measured in real time during the gelation process carried out directly between the parallel
plates of the rheometer. Correlation between rheological parameters and desired sensory properties were established. All the
studied systems presented a gel-like behavior exhibiting different consistencies and degrees of structural stability.
