The Part 2 ingredients were combined and heated to 80° C. Part 2 was added quickly to Part 1 while stirring. Part 3 was added to the mixture of Parts 1 and 2 at 70° C. while stirring. The Part 4 ingredients were combined and heated to 50° C. Part 4 was added to the mixture of Parts 1, 2, & 3 at 50° C. while blending. Part 5 was added with continued blending and cooling. The compositions of Examples 3 and 4 produced light yellow creams. Both creams provide a very smooth feel on the skin that has a less greasy feeling than the composition of Example 2 alone.
