Abstract
The purpose of the present invention is to provide a twin pack aerosol dentifrice having excellent storage stability, with which it is easy to form a high-performance dentifrice composition. This twin pack aerosol dentifrice is provided with a dual-layer container having a filling space for propellant and two filling spaces for stock solution, the dual-layer container being equipped with a discharge mechanism for simultaneously discharging the contents filled in the two filling spaces for stock solution, the twin pack aerosol dentifrice being characterized in that the filling space for propellant is filled with propellant comprising compressed gas, the first filling space for stock solution is filled with a first stock solution composition containing a medicinal ingredient and having a viscosity at 20 DEG C of 1000-125,000 mPa*s, and the second filling space for stock solution is filled with a second stock solution composition not containing said medicinal ingredient and having a viscosity at 20 DEG C of 1000-125,000 mPa*s.
Description
technical field [0001] The invention relates to a two-liquid mixed aerosol dentifrice. Background technique [0002] In the past, as a certain type of dentifrice, it is known that several dentifrice compositions with different compositions are filled in tube-shaped containers, and these several dentifrice compositions can be ejected in strips (for example, refer to patent Literature 1). [0003] Such a dentifrice needs to be uniformly squeezed from the back of the tube-shaped container without rubbing the tube-shaped container in order to obtain a beautiful striped pattern in the ejected product. In addition, since the balance of the discharge amounts of several types of dentifrice compositions changes depending on the extrusion method of the tube-shaped container, several types of dentifrice compositions cannot be extruded at a constant quantitative ratio. Therefore, there is a problem that the desired action and effect expressed by combining several kinds of dentifrice c...
