摘要:
A method of making a personal care composition comprising the steps of: (a) providing a first layer and a second layer which each are fluid at elevated temperature; solid at ambient temperature; and visually distinctive from each other; (b) providing the first and second layers in fluid state at an elevated temperature in isolated vessels; (c) separately dispensing the first layer by a first nozzle and the second layer by a second nozzle, while maintaining the elevated temperature, into a same package having a circle plan view shape; (d) wherein the positions of the nozzles, relative to the center of the package, are maintained during dispensing, wherein the middle point of the nozzles do not coincide with the Z axis running vertically through the center of the package; and (e) cooling the dispensed composition for solidifying in the package.
