You will need–
2 tablespoons glycerin
2 tablespoons corn flower (cornstarch)
1/2 cup distilled water
2 tablespoons rosewater
Directions–
Mix together all ingredients in an ovenproof glass bowl or pitcher. Heat until just boiling and thick, 1 to 2 minutes in the microwave on High (stirring every 30 seconds), or on the stove top in a water bath. The lotion will be clear and jellylike; stir thoroughly and cool completely. When the lotion is cool, pour into a clean, airtight container.
Note: If your lotion becomes too thick, you can thin it by adding water, one tablespoon at a time and stirring thoroughly.
