Formulation of Foundation Makeup (Liquid) Using D-Optimal Mixture Design

Formulation of foundation makeup (liquid) was performed using Doptimal mixture design. Design expert software 7.0 was used to set up D-optimal mixture design and 15 formulations were conducted. Each formulation was judged its properties of pH, viscosity, and skin irritation to obtain the most appropriate composition. The optimum formulation of foundation makeup (liquid) was 227.43 ml of deionized water (DI), 1.40 g of carboxy methyl cellulose (CMC), 4.37 g of triethanolamine (TEA), 20.94 g of propanediol (PD), 31.84 g of titanium dioxide (TiO2), 5.25 g of iron oxide (Fe3O4), 7.0 g of kaolin (Kao), 1.40 g of methyl paraben (MP), 34.97 ml of mineral oil (MO), 5.25 g of stearic acid (SA), 8.75 g of glyceryl monosterate (GMS) and 1.40 g of propyl paraben (PP) based on its properties of pH 6.93, 1722.3cP of viscosity and 0 of skin irritation. Regarding the evaluation sheet performed by the Hedonic scale test, satisfactory scores of foundation makeup (liquid) was 7.4 out of 9

Statistical mechanics of a Feshbach coupled Bose-Fermi gas in an optical lattice

We consider an atomic Fermi gas confined in a uniform optical lattice potential, where the atoms can pair into molecules via a magnetic field controlled narrow Feshbach resonance. The phase diagram of the resulting atom-molecule mixture in chemical and thermal equilibrium is determined numerically in the absence of interactions under the constraint of particle conservation. In the limiting cases of vanishing or large lattice depth we derive simple analytical results for important thermodynamic quantities. One such quantity is the dissociation energy, defined as the detuning of the molecular energy spectrum with respect to the atomic one for which half of the atoms have been converted into dimers. Importantly we find that the dissociation energy has a non-monotonic dependence on lattice depth.Comment: 9 pages, 5 figure
