                                These creams are water continuous cream with low or medium oil content. Most of the formulations contain high quantity of stearic acid as the oil phase. This provides an oil phase which melts above body temperature and crystallizes in a suitable form, so as to be immiscible and gives nongreasy film, and moreover can confirm a very attractive appearance to the product.

                                These creams can be defined as stearic acid in a gel of stearate soap.
