  • Example 1 Invention Compositions
  • Table 1 Table 1 *Including only active compounds including salicylic acid; glycols; methyl diisopropyl propionamide; pH adjuster; and fragrance.
  • Example 2 Restitution and Stability Testing
  • Table 2 The following compositions, as shown in Table 2 were prepared by mixing the ingredients listed below as well as water, ethanol, and additional ingredients and allowing to equilibrate.
  • Restitution testing was performed by loading about 500 milligrams of the composition into a porous applicator consistent with embodiments described herein, such as a porous applicator described in FIG. 2 and having a portion of the porous material to be contacted with keratinous material has an average pore size of about 30 to about 80 microns and a portion of the porous material at the bottom of the base portion of the container having an average pore size of about 90 to 200 microns.
  • Applications were made by dabbing the applicator 20 times, for 5 sec increments, onto a CURAD non-stick adhesive pad having a 496 g mass provided atop the applicator in order to resemble consumer application force.
  • the % restitution was calculated as (initial mass of composition inside applicator -final mass of composition inside the applicator)/(initial mass of composition inside applicator) and expressed as a percent.
  • Stability testing was performed by placing composition into a 4oz. jar and putting the samples into different chambers to test for freeze thaw (e.g., 10 cycles of 20°C to 20°C); or constant temperature exposure: 50°C (one month); and/or 5°C, 25°C, 50°C or 37°C for two months. If the samples showed significant color, pH, viscosity change or phase separation, a failure was recorded.
  • Example 3 Restitution of Different Particulates
  • Table 3 The results of optical microscopy analysis (using Leica DM2500 & DM2500 LED optical microscopes available from Leica Microsystems) to examine the presence of particulates that were able to travel through the pores of the applicator are also shown.
