Sorbitan+Stearate

Sorbitan sterarate is a white to tan-colored solid. This solution is a produced reaction of sorbitol with steraric acid. However, sorbitan stearate is not soluble in water, but can work as an emulsifier. An emulsifier is a mixture of two or more liquids that are un-blendable. Sorbitan sterate can be found in lotions such as Johnson's Baby Lotion.



Sorbitan stearate is an essential ingredient in many lotions and other skin-care products. It acts as a humectant to bind moisture, thicken the product, and stabilize the mixture of water and oils. This stabilization effect is why sorbitan stearate is known as an emulsifier — it allows two liquids, which normally would not blend, to form a stable mix called an emulsion. Many everyday products use this to keep a cream base from breaking apart during long-term storage in vials, jars, and bottles. Separation may still occur, however, when products are subjected to extreme hot or cold temperatures.

The source of sorbitan stearate is berries and other vegetable matter. The compound is derived as a natural alcohol, combining a sugar alcohol called sorbitol with fatty acids from vegetables. Sorbitol can be found in natural sources such as corn, plums, and many other common foods. When the sorbitol and fatty acids react, they create a new compound that retains the humectifying properties of sorbitol, and makes the alcohol an effective skin moisturizer and softener. This is why it is often used in anti-aging formulas, rash treatment creams, and dry skin treatments. The moisturizing properties are also useful in sunscreen lotions and creams
