industries
require more rational, time, and money-saving procedures to achieve
functional and sensorial objectives. We developed a methodology based
on rheology and texture analysis to outline the physical–mechanical
properties of aqueous dispersions of acrylic polymers belonging to
three different classes: carbomers, acryloyldimethyltaurate derivatives,
and predispersed acrylic polymers. Statistical analyses evidenced
a significant correlation between rheological and textural parameters:
viscosity (η) correlates with firmness, while storage (G′) and loss (G″) moduli
with adhesiveness, and stringiness. The results demonstrated that
the combined approach of these two instrumental techniques is useful
to discriminate each cosmetic raw material on the basis of their applicative
specificities and to rationalize their use in personal care products
obtaining a wide range of textural characteristics.
