New positioning of colorimeter in beauty and makeup testing

In August 2026, the Instrument Information Network released a special scheme for the detection of ITA values on human skin in cosmetics, clarifying that the measurement of Lab* color space data using a skin chromameter is a core compliance method supporting the evaluation of whitening efficacy in the "Cosmetic Safety Technical Specifications", further promoting the standardized application of chromameters in the field of beauty and makeup efficacy testing.

Prior to this, the chromaticity measurement aspect of cosmetic whitening efficacy evaluation had long faced issues of inconsistent testing logic and insufficient data interoperability among different institutions, directly affecting the compliance and mutual recognition efficiency of efficacy evaluation reports. The release of this special plan serves as a clear technical basis for the core testing steps across the industry, providing clear compliance reference standards for the selection, operation, and data output of skin chromameter.

From the perspective of the core requirements for compliance implementation, the explicit core logic of this special plan is to use the Lab* color space data specified by CIE as the sole basic data source for ITA° value calculation. This requires that the corresponding skin chromameter must have the ability to stably output standard chromaticity space data, without issues such as data drift or spatial definition deviation. Only when the chromaticity measurement system of the instrument fully matches the regulatory requirements can the subsequently generated ITA° values directly serve as effective supporting data for whitening efficacy evaluation, avoiding compliance failure in the entire evaluation process due to substandard instrument performance.

In the daily operation of beauty and cosmetics efficacy testing, the long-term stability and operational convenience of instruments are equally important. Testing institutions need to maintain consistency in measurement data across different testing cycles, avoiding unacceptable deviations in the measurement data of the same test sample due to performance fluctuations within the instrument calibration cycle, which could affect the rigor of the efficacy evaluation conclusions. At the same time, a standardized data output logic can also directly interface with the existing efficacy evaluation data management system, reducing human errors caused by manual secondary data conversion.

Haopujia's colorimeter fully meets the measurement requirements of the Lab* standard chromaticity space proposed in this special plan. The long-term measurement stability of the instrument has been systematically calibrated, and the data output logic directly adapts to the conventional data processing flow for evaluating the whitening efficacy of cosmetics, eliminating the need for additional complex secondary conversion. It provides stable and reliable instrumental support for the beauty industry to carry out human skin ITA° value testing in compliance, helping relevant institutions efficiently complete the chromaticity measurement part of whitening efficacy evaluation within a standardized framework.
