Definitions
- the present invention relates to a cleansing sheet in which a sheet base material is impregnated with an emulsifying composition for cleansing.
- Cleansing cosmetics using a cleansing composition for removing makeup and the like are widely known.
- the cleansing composition includes a liquid composition that is not an emulsion, an emulsion composition, and the like.
- the cleansing sheet cosmetics are disclosed in, for example, the following Patent Documents 1 to 5.
- Patent Document 1 discloses a sheet-like cleansing material obtained by impregnating a nonwoven fabric with an oil-in-water emulsion composition.
- the oil-in-water emulsion composition is (A) a water-soluble compound having a polyoxypropylene structure having 3 or more moles of propylene oxide added and having no alkyl group having 4 or more carbon atoms and / or no polyoxyethylene structure.
- Patent Document 2 discloses a cleansing material obtained by impregnating a sheet base material with an emulsion cosmetic having a viscosity at 25 ° C. of 200 to 4000 mPa ⁇ s and a viscosity at 50 ° C. of 100 to 2000 mPa ⁇ s. It is disclosed. Patent Document 2 describes an emulsion cosmetic containing 10 to 80% by weight of an oil, 10 to 80% by weight of water, and 0.5 to 10% by weight of a surfactant as the emulsion cosmetic. .
- Patent Document 2 an emulsion cosmetic having a relatively high viscosity and a viscosity at 25 ° C. of 1100 to 1500 mPa ⁇ s is described. Moreover, in the comparative example of patent document 2, the emulsion cosmetics whose viscosity is comparatively low and whose viscosity in 25 degreeC is 150 mPa * s are described. However, Patent Document 2 describes that when the viscosity at 25 ° C. is 150 mPa ⁇ s, the liquid stability and the stability of the impregnated sheet are deteriorated.
- Patent Document 3 discloses a sheet-type cleansing cosmetic in which a sheet base material is impregnated with an emulsion composition having a viscosity at 25 ° C. of 200 mPa ⁇ s or less.
- the above emulsion composition comprises (A) 0.1 to 3% by mass of phospholipids, (B) 0.1 to 15% by mass of liquid oil, (C) 1 to 25% by mass of polyhydric alcohol, (D ) 40 to 85% by mass of water.
- Patent Document 4 discloses a sheet-like cleansing material obtained by impregnating a nonwoven fabric with an oil-in-water emulsion composition.
- the oil-in-water emulsified composition contains 0.01 to 0.5% by mass of an aqueous thickener, 5 to 30% by mass of an oil having a boiling point of 160 to 300 ° C., and water.
- Patent Document 5 discloses a cleansing sheet obtained by impregnating a sheet base material with a liquid cleansing agent composition.
- the liquid cleansing agent composition includes (A) an oil agent having a viscosity at 25 ° C. of 1000 to 50000 mPa ⁇ s and (B) an oil agent having a viscosity at 25 ° C. of 20 mPa ⁇ s or less as oil components.
- the total content of the component (A) and the component (B) in the total oil component is 30% by mass or more.
- the mass ratio ((B) / (A)) between the component (A) and the component (B) is 1 to 5.
