Abstract
A production method for a personal care product applicable to a human body can include a forming step in which a nozzle is moved relative to an object while a composition having fluidity is supplied from the nozzle to the object to form a deposit derived from the composition on the object. A nozzle with a nozzle diameter of 0.01 mm or more and 2 mm or less may be used as the nozzle. In the forming step, the composition can be supplied such that a ratio of a distance between a tip of the nozzle and the object to the nozzle diameter (distance/nozzle diameter) is set to 0.35 or more and less than 3.
Claims20
A method for producing a personal care product applicable to a human body, the method comprising:
- forming a deposit derived from a composition having fluidity on an object, said forming including moving a nozzle relative to the object while the composition is supplied from the nozzle to the object wherein
- the nozzle has a nozzle diameter of 0.01 mm or more and 2 mm or less,
- in said forming, the composition is supplied such that a ratio of a distance between a tip of the nozzle and the object to the nozzle diameter is set to 0.35 or more and less than 3,
- the composition is linearly continuously supplied from the nozzle toward the object,
- in said forming, the composition is supplied such that a ratio of relative moving speed of the nozzle relative to the object in a plane direction to a supply speed of the composition from the nozzle is set to 0.1 or more and 2 or less, and
- a viscosity of the composition at a temperature at which the composition is supplied from the nozzle is 0.1 Pa·s or more and 1 000 Pa·s or less.
