In order to study the thermal behavior of a capsicum oleoresin (OC) composite material used for burning tear bomb, the single component and the composite (KClO 3 + lactose + OC) were tested by HS-STA-002 synchronous thermal analyzer. Differential scanning calorimetry (DSC) and thermogravimetric analysis (TG) were performed at a heating rate of 10°C/min, the results show that the composites have good compatibility because the characteristic peaks of each component in the composites have little change compared with the relative characterization of the composites. The temperature range of the best volatilization effect of pure OC is between 250°C∼350°C; when the temperature is lower than 250°C, it is unfavorable to the thermal diffusion of OC; when the temperature is higher than 350°C, OC will undergo thermal decomposition. In the composite system, the temperature range of the best volatilization effect of OC is between 230°C∼330°C. Compared with the temperature range of the best volatilization effect of pure OC, the temperature range of OC is shifted to the left, but the range is smaller. All these findings can provide theoretical guidance for the formulation design and optimization of this kind of composites.
