Science
Mechanism of Action
SUCROSE BENZOATE/SUCROSE ACETATE ISOBUTYRATE COPOLYMER exerts its effects primarily through two key mechanisms: film-formation and viscosity control. It creates a cohesive, continuous film upon application, which can provide a protective layer on the skin, hair, or nails. Additionally, it skillfully adjusts the viscosity of formulations, allowing for precise control over product consistency. Its Sucrose Acetate Isobutyrate (SAIB) component further refines product flow, acting as a plasticizer and extender to reduce surface imperfections and enhance film integrity and solids content.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has assessed saccharide esters, including the component Sucrose Acetate Isobutyrate (SAIB), concluding them safe for cosmetic use within current industry practices and concentrations. SAIB is also recognized as Generally Recognized As Safe (GRAS) by the FDA for direct food additive use, with an allowable daily intake of 20 mg/kg/day. While a dedicated CIR safety assessment or maximum concentration for this specific copolymer was not identified, the favorable safety profiles of its constituent parts contribute to its overall assessment. EWG rates SAIB with low concern for cancer, allergies, immunotoxicity, and developmental/reproductive toxicity.
