[0061]
[0062] *Baycusan-C1004 was obtained from Bayer Material Science.
[0063] In this example, the water and the water-soluble and water-dispersible ingredients are thoroughly mixed, as are the oil and the oil-soluble and oil-dispersible ingredients, to obtain a water phase and an oil phase. Heat was used, but no phase was heated above about 70°C, and dihydroxyacetone and fragrance were not added until cooled to about 35°C. The oil phase of each sample was added to the water phase of each sample and mixed well in the presence of an emulsifier. An oil-in-water emulsion is obtained. Granules containing optional active agents were prepared by mixing petrolatum and active agents (ie, iron oxide red, iron oxide yellow, and iron oxide black). Moderate agitation was used and the particle / active agent phase was heated to about 50°C. A homogeneous mixture of petrolatum and iron oxide is obtained.

Embodiment 2
[0066] Samples of Example 1 were evaluated for rub-off and evenness of application by visual inspection. The surprising results obtained can be found in the table below.
[0067] surface
[0068] sample
[0069] The ΔE* color difference was obtained after applying the sample to the artificial skin substrate (23 cm x 7 cm) with fingers and rubbing for 60 seconds. A film applicator (1u) was run over the surface to obtain a 25 μm thick film. A piece of white fabric (r=3.5 cm) was applied to the bottom of the plastic dish (r=2.7 cm). Ten (10) minutes after application, a controlled load pressure (30 g / cm 2) place the disc on the substrate surface and move it across the substrate surface using a device (IKA Labortechnik) that pulls the disc at a rate of 2.5 cm / s. The chosen substrate was a solid grip liner, 2mm thick, soft, visco-elastic and hydrophobic. The temperature is maintained at about 21°C and the relative humidity is about 25-40%. Stains were used for easy ...
