  • the present invention relates to a sheet-like substrate, for example, used for sheet-like cosmetic products such as facial masks, patches and wipes.
  • the present invention also relates to a sheet-like cosmetic product manufactured using such a substrate.
  • Facial masks, patches, and wipes are the most popular substrate-based cosmetic products. Such sheet-like cosmetic products are conventionally impregnated with one kind of cosmetic formula. Recently, printing technologies for applying multiple kinds of cosmetic formulas on one sheet-like substrate has been developed in order to address the different concerns of the user's skin.
  • 2015/140283 Al proposes to apply the multiple kinds of formulas on the substrate in a dry stage.
  • this approach has a problem in that a large amount of polyols or oils cannot be used in such a product since they cannot completely dry out. Therefore, products manufactured using this approach do not have the same sensory experience for the user as the packed masks currently sold in the market.
  • WO 2015/097207 Al proposes the selecting of compositions of formulas in order to ensure that two adjacent formulas do not mix on a substrate.
  • the substrate-based products are to be impregnated with large amounts of multiple liquid formulas with different behavior, one specific liquid formula which is more flowable and less absorbent on the substrate can flow on a surface of the substrate and migrate to the adjacent zone for another formula.
  • an object of the present invention is to provide a novel sheet-like substrate suitable for applying multiple kinds of formulas on respective targeted zones thereof with little or no migration of applied formulas between adjacent zones.

  • Table 1 Volume density of conventional nonwoven materials
  • nonwoven materials having such properties are not suitable for manufacturing a substrate in which it is intended that respective targeted zones to which two or more kinds of formulas are to be applied respectively be assigned to the substrate. This is because the applied formulas can relatively freely migrate inside the conventional nonwoven materials.

  • a sheet-like substrate having the above function can be realized by using nonwoven materials having a relatively low volume density as compared with the volume densities shown in Table 1 , that is, a volume density between 0.01 grams/cm 3 and 0.08 grams/cm 3 .
