The first and second agents are both emulsified cream preparations. In each table, the value indicating the content of each ingredient is the value in units of mass% in the first or second agent. The first and second agents were filled with the combinations shown in Tables 1 to 5 into the first and second inner containers of a separate-filled, double-structured container of the same pressure ejection type, and the following measurements were made And evaluation. [Sheets of the first inner container and the second inner container] The first inner container uses PET/Al foil/PE according to the order of the outermost layer/middle layer/innermost layer as the sheet material. In addition, the second inner container uses PET/NY/PE in the order of the outermost layer/middle layer/innermost layer as a sheet. Furthermore, nitrogen is used as the propellant for filling. [Viscosity measurement] The viscosity of the first agent contained in the first inner container and the second agent contained in the second inner container at 30°C was measured using a B-shaped viscometer with a screw holder (manufactured by Toki Sangyo Co., Ltd.) , Model TVB-10R, T-BAR STAGE TS-10). Specifically, the outer container is cut with a cutter, and then the first inner container and the second inner container are cut with scissors, and the first dose and the second dose are taken out. After leaving the obtained first and second doses for 1 day, if it does not reach 50,000 mPa·s, set it as the value after rotating it with spindle No. M4 at 30°C and 12 rpm for 1 minute. If it is 50,000 mPa·s or more, set the value after using the spindle No. TC to rotate at 30°C and 10 rpm for 1 minute.

[Initial discharge amount] Each of 40 g of the cream-like first agent and the second agent described in Tables 6 to 7 was filled into a separate-filled, double-structured container of the same pressure discharge type. After that, it was immersed in a thermostat at 30°C for 30 minutes, and the operation of simultaneously spraying the first agent and the second agent was performed for 5 seconds, and the spray amount of each agent was measured. [Equivalent sprayability] Each of 40 g of the cream-like first agent and the second agent described in Tables 6 to 7 was filled into a separate filling, double-structured container of the same pressure spray type. After that, it was immersed in a constant temperature bath at 30°C for 30 minutes, and the operation of simultaneously spraying the first and second agents was repeated, each spraying 25% by mass filled with 40 g of the second agent, and measuring the first agent The ejection amount, the simultaneous ejection operation is stopped at the moment when all the filled amount is ejected. In addition, the ratio of the measured ejection amount on the mass basis of the first dose and the measured ejection amount on the mass basis of the first dose to the ejection amount of the second dose on the mass basis is shown in each table " Equal sprayability" column.

Specifically, the outer container is cut with a cutter, and then the first inner container and the second inner container are cut with scissors, and the first and second agents remaining in each inner container are taken out, and the mass is measured. For the first dose and the second dose, the ratio of the remaining amount in the inner container was calculated by the following formula. Remaining amount ratio (%) = (mass after full volume ejection)/(mass before ejection) × 100 [Internal pressure measurement] Use WGA-710c (manufactured by Kyowa Electric Co., Ltd.) as a meter regulator, as a small pressure conversion PGM-10KEZ1 (manufactured by Kyowa Electric Co., Ltd.) was used to measure the internal pressure at 30°C. The pressure introduction part of the small pressure conversion machine is pressed against the pressure rod part of the container outside the double structure container of separate filling and the same pressure ejection type for a specific time, and the internal pressure is set to a fixed value. [Measurement of Flexural Rigidity] The flexural rigidity of the sheet was measured at 20°C using a multifunctional pure bending tester KES-FB2-S (manufactured by Kato Tech). Specifically, the multilayer structure sheet used in the inner container was cut into a shape of 2 cm in length × 4 cm in width. Clamp the cut sheet between the fixed chuck and the moving chuck of the testing machine. Then, the maximum curvature of the testing machine was set to 2.5 cm -1 , and the number of cycles was set to 2 for measurement. Curvature: Calculate the slope of the bending moment-curvature curve based on the values at 0.5 cm -1 and 1.5 cm -1 , and set this value as the bending rigidity.
