Eastman Sustane™ SAIB, Eastman Sustane™ SAIB MCT, and Eastman™ SAIB (Sucrose Acetate Isobutyrate) are sucrose-based adhesion promoters used to improve adhesion of products to fingernails, skin, and hair. SAIB is available in a variety of low-viscosity blends for cosmetic and personal care applications.

The inclusion of 10% to 20% SAIB (based on total solids) in solvent-based nail lacquers can result in improved film-former flexibility and adhesion.

In transfer-resistant lipsticks, SAIB can function as a plasticizer to soften the primary film former and improve its adhesion and flexibility. In traditional lipsticks, it can improve wear properties by reducing creeping, bleeding, and feathering.

In epilatories, SAIB is used as a tackifier. Its low odor is often preferred over other typically used tackifiers.

In shampoo and conditioning products, SAIB deposits on the hair to provide body and manageability.
