Plasticizers

Eastman plasticizers are used by the nail care industry to increase the flexibility of films. Consumers expect their nails to look good for five to seven days after a manicure. If films are over-plasticized, they will dry too slowly and become dull because of marring. If the plasticizer is too volatile, it will evaporate and the film will become brittle. Eastman SAIB-90 and SAIB-90EA are available for the nail care industry. Both are a light-colored, stable liquid that is soluble in most alcohols. Though they are very viscous, they have the unique characteristic of changing viscosity abruptly when increasing temperature or adding a solvent.
