The present invention aims to provide a warming composition showing a favorable dispersion stability after long-term storage, a high warming impact, and improvement of zeolite-specific deterioration of feeling of use, and to provide an aerosol formulation containing the warming composition. This object is achieved with a warming composition containing zeolite nanoparticles having an average particle size of not more than 500 nm, wherein the temperature of the composition is rapidly increased by heat generated by hydration reaction between the zeolite and water.

Warming composition and aerosol formulation including same

The present invention has as its object the provision of an aerosol product for forming a gel composition. The aerosol product has high storage stability and can form a desired gel composition easily and stably. The aerosol product for forming a gel composition of the present invention has a double-structure container including a propellant filling space and two liquid concentrate filling spaces and having a discharging mechanism for simultaneously discharging the contents filled in the two liquid concentrate filling spaces. The propellant filling space is filled with a propellant composed of a compressed gas, a first liquid concentrate filling space is filled with a first liquid concentrate composition containing water and a water-soluble alginic acid salt, and a second liquid concentrate filling space contains a second liquid concentrate composition containing water and a dissociative calcium salt. The first liquid concentrate composition and the second liquid concentrate composition are mixed to form a gel composition.

Aerosol product for forming gel composition

The present invention has as its object the provision of a two-liquid mixing-type aerosol product having high formulation stability, being capable of easily forming a discharge material having a desired composition, and providing comfort during use when it is applied to the human body. A two-liquid mixing-type aerosol product of the present invention has a double-structure container including a propellant filling space and two liquid concentrate filling spaces and having a discharging mechanism for simultaneously discharging the contents filled in the two liquid concentrate filling spaces. The propellant filling space is filled with a propellant composed of a compressed gas. A first liquid concentrate filling space is filled with a first liquid concentrate composition having a viscosity of 1 to 1000 mPa&#xb7;s at a temperature of 20&#xb0; C. A second liquid concentrate filling space is filled with a second liquid concentrate composition having a viscosity of 1 to 1000 mPa&#xb7;s at a temperature of 20&#xb0; C. The discharging mechanism has a function for breaking the first liquid concentrate composition and the second liquid concentrate composition down into fine droplets and discharging these liquid concentrate compositions as mists.

Two-liquid mixing-type aerosol product

The present invention has as its object the provision of an aerosol product for forming a cooling gel composition for the human body. The aerosol product can easily and stably form a cooling gel composition for the human body which has high storage stability and which provides comfort during use and a sufficient cooling effect. The aerosol product for forming a cooling gel composition for the human body of the present invention has a double-structure container including a propellant filling space and two liquid concentrate filling spaces and having a discharging mechanism for simultaneously discharging the contents filled in these two liquid concentrate filling spaces. The propellant filling space is filled with a propellant composed of a compressed gas. A first liquid concentrate filling space is filled with a first liquid concentrate composition containing a hydrated endothermic substance dispersed in a liquid medium. A second liquid concentrate filling space contains a second liquid concentrate composition containing water. The first liquid concentrate composition and the second liquid concentrate composition, which have a viscosity of 1,000 to 125,000 mPa&#xb7;s at a temperature of 20&#xb0; C., are mixed to form a cooling gel composition for the human body.
