METHOD OF MAKING COMPOSITIONS COMPRISING MULTIPLE LAYERS

摘要

Disclosed is 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. Also disclosed is 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 into a same package while maintaining the elevated temperature, wherein the package may be rotated during the dispensing; (d) wherein at least one of steps (i) through (iv) takes place during the dispensing; and (i) the dispensing of the first and second nozzles are started and/or completed at a different time point; (ii) the rotation of the package is completed prior to the completion of dispensing; (iii) the direction of rotation of the package is altered during the dispensing; (iv) the flow rate of at least one of the first and second layers are altered during dispensing; (e) cooling the dispensed composition for solidifying in the package.
