Pour the sweet almond oil, beeswax, coconut oil and honey into a container that can be used as a double boiler (I always use a large mason jar).Fill a medium sized sauce pan with a few inches of water.Place the container into the sauce pan and bring the water to a gentle boil.As the ingredients start to melt, stir the ingredients together (I use a chopstick for this! You can use a popsicle stick as well)Warm up the rose water. I do this in another jar in the same sauce pan. You want these to be right around the same temperature.Pour the heated rose water into a food processor. Turn on the food processor and slowly add the melted oil/wax mixture and corn starch while the food processor is on (I use a large bowl and a hand blender which I think is much easier to clean!)Use a spatula to move your new lotion into the desired container (I like mason jars for this too).
