Microslide used in step (1) and (2) will clean in advance.
2 microslides selecting for use in the step (2) and 2 microslides in the step (1) are same batch microslide.
2 microslides selecting for use in the step (2) are 2 microslides in the step (1).
Cosmetics described in the step (2) are the cosmetic skin-care product of thickness states such as cream frost, emulsion.
Standard smear described in the step (2) comprises for to draw smear method to be prepared from through pressure: sample is sandwiched between two microslides that intersect anyhow, moves two microslides then, make it overlapping, the limit flanging is drawn again, promptly obtains smear.
Further, said ultraviolet spectrum is made up of wavelength and intensity; Said ultraviolet (UV) A transmitance spectrogram is made up of wavelength and transmitance.
The present invention is directed to thickness state products such as different skin protection cosmetics cream frosts, emulsion and have the ability of different ultraviolet ray filterings, a kind of method that detects the UVA sun-proof result of thickness state products such as skin protection cosmetics cream frost, emulsion through the sunshine ultraviolet spectrum is provided.
The advantage of invention
(1) with low cost: the ultraviolet source of sunshine for obtaining easily on the ground;
(2) rapidly and efficiently: the shooting of ultraviolet spectrum only needs get final product several seconds;
(3) accuracy is high: because ultraviolet band belongs to the non-visible light wave band, the embarrassment that the ultraviolet spectrum testing result has avoided artificial sense to estimate;
(4) applicability is strong: the required ultraviolet spectrometer (UVS) of this method is simple to operate, and this method can be applied.
Beneficial effect:
Ultraviolet source of the present invention is sunshine, and is cheap and easy to get, and detection method of the present invention rapidly and efficiently, and accuracy is high, and applicability is strong.
