Clear nail polish top coat formulations prepared without the use of toxic compounds, such as toluene, are provided. The compositions utilize cellulose acetate butyrate (CAB) as a main resin a discussed are the effects of numerous solvents, plasticizers, co-resins, and/or additives on CAB's solubility. For example, the type and ratio of solvents used are related to the selected CAB grade's molar ratio of butyryl, acetyl, and hydroxyl R-groups. Performances measures include, but are not limited to, transmitted haze, reflected haze, hardness, viscosity, shrinkage, tensile strength, and elastic modulus. Additionally, the effect of filtration on the transmitted haze is also discussed. |
