Glyceryl Stearate is a naturally-derived emulsifier, thickener and stabilizer. It is an ingredient that is used in order to mix oil and water. I love this ingredient because it is the natural glyceryl ester from stearic acid (glycerin & stearic acid). It also acts as an emollient, which helps prevent moisture loss in your skin. I use Glyceryl Stearate as part of my goat-milk lotion and Simply Radiant Face Cream formulations because of its gentleness and effectiveness and also because it is naturally derived from vegetarian sources.
