Solubility: less than 1 mg/mL at 68° F; In water, 300 mg/L at 25 ? (est); Insoluble in water; Soluble in alcohols, esters, ethers, ketones Stability: Stable under recommended storage conditions.; The physical properties of t-butyl perbenzoate are that of an intermediate fire hazard; however, other sources refer to it as a fire hazard with 8.16% active oxygen. The liquid at 99% purity showed a slow pressure rise with only 1 g of igniter; therefore, it is not a deflagration hazard. It also has a low shock or impact sensitivity.
