Glyceryl Isostearate is a plant-based ester made from glycerin. This means that it is derived from fatty acids and will act as a humectant and moisturizer. It is also used as an emollient and thickening agent.
So what is an ester? This might seem like a scary scientific term, but believe us this is a natural thing. In simple chemistry terms, both fats or oils are examples of esters. If an ester is liquid at room temperature it is as oil, and if not it is a fat. We know this just from our everyday lives.
Glyceryl Isostearate is used in our Natural Sunscreen to keep everything together and to act as a moisturizer. It is plant-based and good for your skin.
