Definitions

  • the present invention is directed to a cosmetic sheet that is applied to the skin for diminishing the appearance of fine wrinkles and spots of the face.
  • Patent Literature 1 proposes a cosmetic sheet that is applied to the skin for diminishing the appearance of fine wrinkles and spots of the face.
  • This cosmetic sheet is obtained by mixing cosmetics into a solution comprising a high-molecular compound dissolved in water or a solvent, followed by electrospinning the resulting liquid.
  • Patent Literature 2 discloses a makeup sheet-form cosmetics with a sheet consisting of nanofiber obtained by an electrospinning method.
  • This makeup sheet-form cosmetic is such that a sheet of nanofiber comprises a base material sheet on one of the surfaces thereof, and the sheet of nanofiber is peelable from the base material sheet.
  • Patent Literature 2 states that "when a laminated film can be peeled off from a nanofiber sheet, it is preferable to provide a peeling treatment, such as a silicone resin treatment or a corona discharge treatment, on the surface of the film that is opposite to the nanofiber sheet for improvement of detachability.”
  • a peeling treatment such as a silicone resin treatment or a corona discharge treatment
  • the nanofiber sheet cannot be easily peeled off from the base material due to the high degree of adhesion of the nanofiber sheet to the base material.
  • wrinkles of the nanofiber sheet will be made, which makes it impossible to apply the nanofiber sheet evenly to the face or the like.
  • Patent Literature 1 Japanese Laid-Open Publication No. 2008-179629
  • Patent Literature 2 Japanese Laid-Open Publication No. 2012-12339
  • An objective of the present invention is to provide a cosmetic sheet, which allows for easy handling of a nanofiber sheet obtained by an electrospinning method, and which allows the nanofiber sheet to be easily transferred from a base material sheet to the skin.
  • a cosmetic sheet comprising: a base material sheet; a peelable nanofiber sheet provided on a surface of the base material sheet; and a cover sheet provided on a surface of the nanofiber sheet, where hydrophilization treatment is performed on the base material sheet and the nanofiber sheet is formed by an electrospinning method.
  • the cosmetic sheet according to Item 1 where hydrophilization treatment on the base material sheet is performed by treating the base material sheet with a hydrophilization treatment solution containing a hydrophilizing agent selected from the group consisting of an alkyl phosphate salt, a trialkylglycine derivative and a (poly) alkylpolyalkyleneamidedialkylglycine derivative.
  • (Item 3) The cosmetic sheet according to Item 1 or 2, where the nanofiber sheet has a positive electric charge, and the base material sheet has a negative electric charge.
  • (Item 4) The cosmetic sheet according to any of Items 1 to 3, where the base material sheet is a non-woven fabric.
  • (Item 6) The cosmetic sheet according to Item 5, where the high-molecular compound is polypropylene.
  • (Item 7) The cosmetic sheet according to any of Items 1 to 6, where the base material sheet contains at least one type of cosmetics selected from the group consisting of a moisturizing cream, a skin cream, a whitening cream, a milky lotion, a skin lotion, a beauty essence and a beauty gel.
  • a cosmetic laminated body comprising: a laminated-body base material sheet; an adhesive layer laminated on a surface of the laminated-body base material sheet; and a cosmetic sheet laminated on a surface of the adhesive layer, where the cosmetic sheet comprises a base material sheet, a peelable nanofiber sheet provided on a surface of the base material sheet, and a cover sheet provided on a surface of the nanofiber sheet, where a part of the adhesive layer is exposed and the cover sheet is applied to the exposed adhesive layer, and where hydrophilization treatment is performed on the base material sheet and the nanofiber sheet is formed by an electrospinning method.
  • hydrophilization treatment is performed on the base material sheet and the nanofiber sheet is formed by an electrospinning method. Accordingly, when the base material sheet is held by a hand and the nanofiber sheet is applied to the skin, moisture on the skin surface works on the base material sheet and the nanofiber sheet, which causes the electric charge possessed by nanofiber sheet and the electric charge possessed by the base material sheet to disappear rapidly. As a result, the mutual attraction by static electricity is lost between the nanofiber sheet and the base material sheet, and nanofiber sheet is easily peeled off from the surface of the base material sheet, which allows the nanofiber sheet to be applied to the skin.
  • the electric charge of the base material sheet is opposite from the electric charge of the nanofiber sheet.
  • the nanofiber sheet and the base material sheet are attracted to each other by static electricity.
  • the electric charge of the base material sheet and the nanofiber sheet rapidly disappears, which facilitates the nanofiber sheet to be peeled off from the base material sheet.
  • the reason why the electric charge rapidly disappears is assumed to be due to the hydrophilization treatment performed on the base material sheet and the base material sheet is greatly influenced by the moisture of the skin surface.
  • the hydrophilization treatment performed on the base material sheet ensures that the nanofiber is transferred from the surface of the base material sheet to the skin.
  • a laminated-body base material sheet, an adhesive layer on the laminated-body base material sheet, and a cosmetic sheet of the above-mentioned configuration on the adhesive layer are laminated.
  • the laminated-body base material sheet can be held by the fingers to apply the nanofiber sheet to the skin.
  • the fingers will not touch the nanofiber sheet, and such feature provides favorable handling characteristics.
  • the base material sheet retains cosmetics such as cream, or when cosmetics are applied on the skin and then the nanofiber sheet is applied on the skin, the nanofiber sheet retains the cosmetics and allows the skin to absorb the cosmetics gradually. This produces a superior beauty effect, and further, this prevents cosmetics from being dried. Accordingly, even if a cream of low viscosity is applied, it becomes possible to prevent the cream from being dried, and it becomes possible to apply the cream to the skin uniformly.
  • a traditional disadvantage of a cream with low viscosity is that it is difficult to handle since the cream will drip when applied to the skin.
  • cosmetics such as a cream is retained by the nanofiber sheet. Thus, it will not be necessary to make viscosity of cosmetics high.
  • the cosmetic sheet by applying the cosmetic sheet to the skin, the moisture in the keratin of the skin is prevented from evaporated. Thus, it is assumed that an above average amount of moisture remains in the stratum corneum.
  • the beauty effect can be enhanced by the synergetic effect of the cosmetic sheet and the beauty essence.
  • the reason of the beauty effect is assumed that the sheet helps the ingredients of the beauty essence to be infiltrated deep inside the stratum corneum, which recovers elasticity of the skin, and as a result, the sulcus cutis portion, which forms fine texture, is tightened and the fine texture is improved.
  • nanofiber sheet applied to the skin has high adhesiveness to the skin.
  • the strength of adhesion of the nanofiber sheet to the skin will not diminish.
  • the nanofiber sheet can simply be removed by pinching and peeling it off with fingers.

  • the diameter of the nanofiber was 200 nm.
  • a cosmetic sheet with a nanofiber sheet laminated on a non-woven fabric was obtained.
  • evaluation By using the cosmetic sheet obtained in Example 1, the following were evaluated: (A) the moisture content of the skin when a beauty essence was applied to the skin followed by subsequent application of the cosmetic sheet to the skin; and (B) the transition of fine texture on the skin when a beauty essence was applied to the skin followed by subsequent application of the cosmetic sheet to the skin. -
  • a nanofiber sheet was applied thereon. After letting the nanofiber sheet stand for 6 hours, the sheet was gradually peeled off from the skin.
  • the moisture content of the skin was measured at the time immediately after the peeling of the sheet, 2 hours after the peeling of the sheet, 4 hours after the peeling of the sheet, and 6 hours after the peeling of the sheet.
  • the moisture content of the skin was measured using a Tewameter TM-300.
  • the test subjects were kept in an experiment room of constant temperature and humidity, at the temperature of 25 degree Celsius and the relative humidity of 30 %, for 30 minutes so that the transmission amount of moisture on the surface of the skin would be constant, and the Tewameter was pressed against the region of the face to be measured.
  • the beauty essence was applied to the skin of the face, and the beauty essence was left to stand for 6 hours.
  • the moisture content of the skin was measured 6 hours past the application of the beauty essence, 2 hours thereafter, 4 hours thereafter, and 6 hours thereafter in a similar manner as described above.
  • the amount of the beauty essence applied was the same as when the nanofiber sheet was used.
  • the fine texture of the skin for each subject was evaluated at the time immediately after the sheet was peeled off, 2 hours after the sheet was peeled off, 4 hours after the sheet was peeled off, and 6 hours after the sheet was peeled off.
  • a replica method was used for the evaluation of fine texture. Specifically, an evaluation was made by creating a replica image of the skin, using ABS-01-W, a reflection replica creating kit by Asahibiomed Corp.
  • a burette whose cock opening was adjusted to supply 10 g distillated water per 30 seconds, was once dried. Then the burette was fixed such that the tip of the burette is arranged 5 mm above in a vertical direction from the uppermost part of the test piece attached to the device with the inclination. About 60 g of distillated water was put in the burette from the above.
  • the time (seconds) was measured from the moment when the liquid started to drop from the tip of the burette towards the non-woven fabric test piece until the moment when the test piece was no longer able to retain the liquid and the liquid started to escape from the bottom of the test piece, which was defined as the degree of hydrophilicity of the non-woven fabric. A higher numerical value is considered as a higher degree of hydrophilicity. (Test result) It was found that the moisturizing effect was advantageously high and the fine texture would be improved when the beauty essence was applied to the skin followed by subsequent application of the nanofiber sheet to the skin.
  • lifting effect generally refers to an effect of reducing the depth of the wrinkles, hence lifting up the skin.
  • the up-lift effect similarly means that a beauty effect is observed such as allowing the skin on which the sheet is applied to be lifted up so that wrinkles become shallower, and the like.
  • An instant up-lift effect refers to a change in the skin and a beauty effect obtained within 24 hours after the application of cosmetics or application of the sheet.
  • Fig. 9 shows a representative replica image.
  • Fig. 10 shows the transition in the number of ridges of fine texture in the case where only the beauty essence was used and in the case where the beauty essence and the sheet were used together.
  • Fig. 11 shows the transition of the moisture in the skin in accordance with the passage of time from immediately after the sheet was peeled off.
  • the primary factor is the recovery of the skin elasticity.
  • the sheet helps the ingredients of the beauty essence to be infiltrated deep inside the stratum corneum, which recovers the skin's elasticity, and as a result, the sulcus cutis portion, which forms fine texture, is tightened and the skin fine texture is improved. (That is, the distance between sulcus cutis become narrower, and cristae cutis become uniform size) Since this result is not observed from the effect by the beauty essence alone, it is considered to be due to the co-application effect of the sheet.
  • Fig. 12 shows a graph of the transition of average values of the number of ridges of fine texture per 1 mm in the case of the beauty essence alone and in the case of the co-application with the sheet, obtained from the replica images, where the graph compares the transition between the beauty essence alone and the co-application with the sheet.
  • the number of ridges of fine texture prior to the application is defined to be 100 %
  • the application of the beauty essence alone and with the sheet decreased the number of ridges of fine texture by 40 and 50 %, respectively.
  • the number of ridges of fine texture gradually returned to original after the peeling off of the sheet (after the application).
  • the number of ridges of fine texture returned to the original value observed prior to the application of the beauty essence alone
  • the number of ridges of fine texture increased 6 hours after the co-application with the sheet compared to that prior to the application. Accordingly, it is understood that the co-application with the sheet has a better effect of improving the skin fine texture.
  • the present invention provides a cosmetic sheet for diminishing the appearance of fine bumpiness of the skin, such as fine texture of the face, for improving moisture retaining property, and for improving the skin texture.
