Aluminum stearate

* Fine, white Aluminum salts that are produced using stearic acid.

Acts as a viscosity (resistance to flow) moderator, suspending agent (keeps the oil and water parts of an emulsion from separating), and thickening agent. Mainly used in products that require viscosity stabilizers like cleansing gels, shampoos and lotions. Because of its ability to also suspend color, you can also find it in several makeup products like foundation and liquid eyeliner.
