The electrostatic atomizer 10 of structure more than having can use as shown, for example, in fig. 2.Tool is shown in Fig. 2 Having can be with the electrostatic atomizer 10 of the hand-held for the size being hold by one hand.In electrostatic atomizer 10 shown in Fig. 2, Fig. 1 Shown in the component of structure chart be all contained in columnar shell 20.In one end 10a configuration of the length direction of shell 20 There is nozzle (not shown).Nozzle is so that the emission direction of the composition and the vertical consistency of shell 20, and towards skin side in convex The mode of shape is configured in the shell 20.It, can be with by making spray nozzle front end be configured to convex up towards skin in the vertical of shell 20 Make to be not easy to be attached to shell with composition by spraying, overlay film can be stably formed.

Make electrostatic atomizer 10 work when, user, i.e. by the desired ultraviolet light of electrostatic spray on the skin prevent The people that overlay film is formed on imperial position holds the device 10 with hand, will be configured with one end of the device 10 of nozzle (not shown) Site of administration of the 10a towards progress electrostatic spray.In Fig. 2, show one end 10a of electrostatic atomizer 10 towards user Forethiga on the inside of state.In this state, the switch of device 10 is opened and carries out electrostatic spraying processes.By logical to device 10 Enter power supply, electric field is generated between nozzle and skin.In the embodiment shown in figure 2, apply positive high voltage, skin in nozzle Skin becomes cathode.If generating electric field between nozzle and skin, the spraying of spray nozzle front end portion uses composition because of electrostatic induction And polarize, front end portion becomes cone cell, and the spraying drop with composition of electrification is by boring front end along electric field, towards skin quilt It is ejected to aerial.If as solvent ingredient (a) from be ejected to space and electrification it is spraying evaporated in composition, spray The charge density on mist composition surface becomes surplus, repeats to be made fine and in spatial spread, arrival skin because of Coulomb repulsion Skin.At this point, using the viscosity of composition by spraying by appropriate adjustment, spraying the composition can be made to reach with the state of drop Site of administration.Alternatively, the volatile materials as solvent can also be made to volatilize from drop, made during being ejected to space As the polymer solidification with overlay film Forming ability of solute, while elongation strain is allowed to by potential difference and forms fibre Dimension, makes the fiber accumulations in site of administration.For example, if improving the viscosity for using composition by spraying, be easy to make the composition with The form of fiber is piled up in site of administration.The porosity being made of the deposit of fiber is formed on the surface of site of administration as a result, Overlay film.The porosity overlay film being made of the deposit of the fiber containing ultraviolet protection agent can also be by adjusting nozzle and skin The distance between or voltage that nozzle is applied formed.

During carrying out electrostatic spraying processes, there is high potential difference between nozzle and skin.However, due to impedance It is very big, it is therefore, extremely small in the electric current of human body circulation.Present inventor has been acknowledged by lower generated with for example usual life It is compared caused by electrostatic in the electric current of human body circulation, it is small several in the electric current of human body circulation during carrying out electrostatic spraying processes A order of magnitude.

When forming the deposit of the fiber comprising ultraviolet protection agent by electrostatic spraying processes, the rugosity of the fiber with When equivalent circle diameter indicates, preferably 10nm or more, more preferably 50nm or more.Additionally, it is preferred that being 3000nm or less, more preferable For 1000nm or less.The rugosity of fiber is observed for example, by scanning electron microscope (SEM), and fiber is amplified to 10000 times It is observed, defect (block of fiber, the cross section of fiber, drop) is removed by its two dimensional image, arbitrarily selects 10 fibers, The line orthogonal with the length direction of fiber is drawn, can be measured by directly reading fibre diameter.

Have by the overlay film that electrostatic spraying processes are formed by the deposit as fiber in the surface side of the fiber constituted There is the ultraviolet protection agent there are ingredient (c) to support overlay film.The surface side of fiber refers to a part on surface or surface, fiber Between.The compatibility for additionally depending on polymer Yu ingredient (c) with the content of ingredient (c) in composition by spraying, if it is about 1 mass % More than, then fiber swelling and softening, the tracing ability raising to skin constituted, further ingredient (c) is easy the fibre from composition It is oozed out in dimension, it is easy to form between the fiber and fiber that are constituted that ultraviolet protection agent supports overlay film；On the other hand, such as Fruit uses the content of the ingredient (c) in composition less than 1 mass % by spraying, then ultraviolet protection agent supports overlay film and is not easy to be formed in institute The surface of the fiber of composition.If ultraviolet protection agent supports overlay film and is formed in the fiber for constituting overlay film in this way, with skin It is close fitting to improve, have the tendency that overlay film transparence, close to natural appearance.Further, the duration due to fitting closely It improves, therefore, the condition improvement of moisture retention or skin to skin is effective.In addition, these close fitting and ultraviolet lights are anti- The effect of the uniformity of imperial effect is coated with by aftermentioned liquor to be further enhanced.

In the case where the skin containing sweat or sebum etc., pass through composite parts (c) in the fibre, then fiber swelling, hold Easily plasticizing.For example, by skin of the identical composition to the metal surface of moisture-free or oil and containing moisture or oil Surface, such as palm, carry out electrostatic spray 5 seconds and in the case where making film, if through when observe the variation of fibre diameter, Compared to the fiber of electrostatic spray to metal surface, timely diameter increases the fiber of electrostatic spray to skin surface due to swelling. In this way, be formed by by electrostatic spray wrap fibrous overlay film because in skin oil and moisture be plasticized and become more to become It is soft, so that fiber itself promotes the tracing ability of dermatoglyph, in addition, ingredient (c) by fibrin formation, be present in fiber surface or Between fiber and fiber, fibrous overlay film is wrapped as a result, and is translucent or transparence, and imparts natural appearance.In overlay film It is formed in the case that object is the skin containing sweat or sebum etc., the fibre diameter due to caused by swelling meets below (1) formula.

(spinning being carried out to skin, the fibre diameter after 30 seconds) > (spinning is carried out to metal plate, the fiber after 30 seconds is straight Diameter) ... (1)

It is measured as follows as spraying with the content of the ingredient (a) of composition, ingredient (b) and ingredient (c).As volatilization The ingredient (a) of property substance be not present in be formed by overlay film or even if there are volatilize, therefore, to being formed by overlay film It is measured with the state for only containing ingredient (b) and ingredient (c), content proceeds as follows measurement.

<using the measuring method of the ingredient (a) of composition, the content of ingredient (b) and ingredient (c) by spraying>

Have with solution state using liquid chromatography (HPLC) separation identification or using infrared spectrophotometer (IR) into The method of row identification.In liquid chromatography, due to being eluted since the biggish ingredient of molecular weight, accordingly it is also possible to pass through molecule The prediction of amount, the elution site of ingredient identify composition.IR can also identify functional group according to each absorber when analyzing It is identified, can usually be identified by comparing the standard drawing of commercially available additive and the IR figure of ingredient.

<measuring method for being formed by the content of the ingredient (b) and ingredient (c) in overlay film>

The exploration for can dissolve the solvent of overlay film, after overlay film is dissolved in solvent, utilizes liquid chromatography (HPLC) Separation identification is identified using infrared spectrophotometer (IR).
