Sensory Enhancers
Starches
Starches are polysaccharide granules extracted from corn. Their modification with n-octenylsuccinyl (n-OSA) group through an esterification transforms them into sensory enhancers as they become more hydrophobic & oil-absorbing.
In emulsions, n-OSA starches reduce the perceived oiliness, the tackiness, and give the skin a powdered & matte finish.
