Scope

Scope: This document specifies the test methods for the dandruff removal efficacy of products with dandruff removal functions. This document is applicable to hair care products with dandruff removal efficacy. Externally applied dandruff removal products can refer to this document for testing; Main technical content: 1. Principle 1.1 Human efficacy evaluation test: Due to the rapid division of keratinocytes on the scalp and the active growth of microorganisms, the epidermal layer of the scalp is shed faster, resulting in dandruff. The main manifestations are visible flaking of keratinocytes, often accompanied by imbalance of water or oil content and itching. Therefore, under the specified use conditions, this method evaluates the overall efficacy of dandruff removal products by assessing the statistical differences in dandruff-related parameters before and after product use, or the statistical differences in test results between the control group and the experimental group, using visual evaluation or dandruff analysis equipment as the evaluation criteria. 1.2 Carrier soaking antimicrobial test: Malassezia furfur is also considered one of the main causes of dandruff formation. Therefore, many dandruff removal products add functional substances to control the growth of Malassezia furfur on the scalp and improve dandruff. For products with such dandruff removal principles, the inhibitory effect of the sample on Malassezia furfur can be used as an evaluation indicator of the dandruff removal performance of the sample. The test uses Malassezia furfur as the indicator species and pigskin as the test carrier. After covering the dandruff removal product on the carrier and acting for a specified time, the number of colonies on the carrier is recovered, and the antimicrobial value is calculated. By comparing the inhibitory results of Malassezia furfur between the control sample and the experimental sample, the dandruff removal effect of the sample is evaluated. 1
