Prior to taking any images, the product was allowed to dry for 15 minutes. The image of the marked area was then taken by a built-in CCD-camera. The connection of the Visioscan VC 98 to the PC was done via an image digitalization unit which configures the image in 256 gray level pixel by pixel, where 0 is black and 255 is white. The SELS software calculated surface and texture roughness parameters. The differences in roughness levels were recorded and the percentage improvement was calculated using the pre-application values as a baseline. Positive values indicate an increase in smoothness, and negative values indicate an increase in roughness. This procedure was performed with both the base coat compositions and the top coat compositions.

  • the optical method used for measuring is the digital stripe projection technique, based on digital micro mirror projectors. Stripes with sinusoidal intensity of brightness are projected onto the surface of the measuring object and the projection, (the stripes changed by the height profile of the measuring object) is recorded at a defined triangulation angle by a CCD camera. The topography of the measuring object is calculated from the stripes' position and the grey value of all registered individual image points. Depending on the measurement task, different stripe projection procedures can be used. The 3D measurement effect is achieved by the fact that minute elevation differences on the surface deflect the parallel projection stripes and that these deflections constitute a qualitative and quantitative measure of the skin profile.
  • top coat 0.06g was applied to the 20 cm 2 substrates as described in Example 2 to which the base coat had been. Images were taken of the marked area before and after application of foundation. Smoothness is determined using this method by ascertaining the smoothness depth R4, which is the area of the void space in the surface of the film between a line at the highest point on the surface of the film and a line that is the mean distance between the high point and the low point of the surface. Percentage improvement was calculated using the pre-application values as a baseline. Positive values indicate an increase in smoothness, and negative values indicate an increase in roughness (decrease in smoothness).

  • the disc was subjectively evaluated with regard to the amount of composition retained thereon. Data obtained from this test demonstrated better non- transfer imparted by the base coat Compositions A and B and by top coat Composition C as compared to the Covergirl base coat and top coat formulations. No. Amount of material transferred onto the disc is estimated subjectively.
  • the test specimen preparation and materials are necessarily different from ASTM. Accordingly, a nylon substrate is used instead of steel; the product is cast on substrate instead of tape applied to substrate, and a breathable nylon fabric backing is used in lieu of a polyester film backing.
  • the peel test provides very repeatable differentiation between the adhesive properties of the foundation to the substrate by virtue of the nylon fabric being peeled off.
  • the data shows that the two-part compositions of the present invention provided superior resistance to delamination from the synthetic skin substitute than a leading foundation brand.

Abstract

L'invention concerne des compositions à deux couches et des procédés de formation de pellicules cosmétiques sur une surface biologique. Lesdites compositions sont durables, résistantes au transfert, hydrophobes, oléophobes, non migrantes, confortables à porter et capables de combler de fines ridules et rides. Lesdites compositions à deux couches contiennent essentiellement une composition de couche de base hydrophile et une composition de couche supérieure, et servent à la formulation de cosmétiques et de produits de soins personnels.
