Sunscreen index(SPF)Identification requirements
The maximum can be marked by the original regulationsSPF30+Adjust toSPF50+
SPF<2Time,Sunscreen effect shall not be marked
SPF> 50Time,Should be identified asSPF50+
2≤SPF≤50Time,The actual measurement shall be markedSPFvalue
SPFValue is2~5 (include2and5)Time,Identification measurementSPFvalue;
SPFValue is6~50 (include6and50)Time: 
Identification upper limit:MeasuredSPFvalue
Identification lower limit:①And②Smaller value between.
①Measured value95%Lower limit of confidence interval
②Less than the measured value5The maximum integer multiple of both
SPFValue greater than50:
Measured value95%Lower limit of confidence interval is greater than50Time,Sunscreen of sunscreen cosmetics
index(SPF)Should be marked 50+ .
WhenSPFValue greater than50,And the measured value95%Lower limit of confidence interval is less than or equal to50Time
Identification upper limit: 50+
Identification lower limit:Measured value95%Lower limit of confidence interval.

Sunscreen cosmetics claiming waterproof effect
Two conditions:Tested for water resistance,And the waterproof performance test results show that after bathingSPFThe value is reduced by no more than50%of.
Annotation method:
At the same time, mark before and after bathingSPFvalue
Label only after bathSPFvalue
Do not mark only before bathingSPFvalue.
UVAProtection effect identification
Critical wavelength of sunscreen cosmetics(CW) Greater than or equal to370nmTime,
Can identify broad-spectrum sunscreen effect.
Identification mode:
According to the measuredPFAValue identificationUVAGradePA
PFA<2Time,No identificationUVAProtective effect
PFA 2~3Time,Identified asPA+
PFA 4~7Time,Identified asPA++
PFA 8~15Time,Identified asPA+++
PFA> 16Time,Identified asPA++++
Sunscreen cosmetics sunscreen index Waterproof performance Critical wavelength Long wave ultraviolet protection index, etc,Should be in accordance with standard Determine according to the specified inspection method,If necessary, refer to the international standard group(ISO) Relevant inspection methods issued.
