It’s not exactly new for consumers to want their makeup to survive the day. Between weather, work, and workouts, color cosmetics have their work cut out for them. SAIB (sucrose acetate isobutyrate) and AQ™ polymers from Eastman™ promote adhesion and form films to help makeup stay where it belongs.
These sucrose-based adhesion promoters allow color cosmetics to better adhere to skin and hair.
Derived from sucrose, a natural sugar
Water-white, clear, no odor
Nonyellowing; stable to UV light exposure
Improved adhesion to fingernails and skin
Extended transfer, wear, and water resistance
Increased film flexibility
Improved emulsion stability
Excellent solubility and compatibility with solvents, polymers, and modifiers
Reduced evaporation rate of aroma chemicals
Low volatility over a wide temperature range
Modification of film-former without appreciable loss of film hardness
Lipstick formulations using more polar vegetable waxes, oils, and esters are compatible with Eastman Sustane™ SAIB. In traditional lipsticks, SAIB reduces creeping, bleeding, and feathering.
In transfer-resistant lipsticks, it can act as a plasticizer to soften the primary film-former and improve its adhesion and flexibility.
The concentration of SAIB used in lipsticks is typically 5–10 wt%.

These highly versatile, water-dispersible polymers provide film forming properties to improve water and smudge resistance.
Adhere to skin and hair
Water, smudge, and high humidity resistance
Provide low viscosity aqueous dispersions at <30% solids
Form clear films at room temperature from aqueous dispersions
Aid the dispersion of hydrophobic ingredients in water-based formulations
Disperse directly in water without the assistance of emulsifiers, organic cosolvents, inorganic bases, amines, or other additives
AQ™ Polymer Products
AQ™ Polymers Application
AQ™ 38S and 55S impart a non-greasy feel to liquid makeup.
AQ™ 55S is the preferred AQ™ polymer for water-based makeup and mascara because it has better film integrity when combined with other cosmetic ingredients. It improves water and smudge resistance in these products.
