Abstract

The invention discloses a method for detecting anti-irritation of an anti-irritation product. The method for detecting the anti-irritation of the anti-irritation product comprises the following stepsof 1) obtaining an image of skin or a skin mimic obtained after patch treatment, wherein a patch is coated with a gel composition comprising the anti-irritation product and an irritant; and 2) measuring an erythema feature value of the skin or the skin mimic in the image. The invention also discloses a method for detecting the irritation of a cosmetic raw material, the gel composition and the patch. The detection method provided by the invention not only has good repeatability, but also can more accurately score the results of irritation antagonism; meanwhile, the subjective influence of people is avoided; and therefore, the irritation antagonism effect of the anti-irritation product is more accurately and objectively evaluated.

Description

technical field [0001] The invention belongs to the field of cosmetics, and specifically relates to a method for detecting the irritation of cosmetic raw materials and an anti-irritation product for anti-irritation products. The invention also relates to a gel composition and a patch. Background technique [0002] The patch test is greatly affected by factors such as the patch substrate, individual differences, and interpretation methods. The choice of patch substrate for product irritation or antagonistic stimulation test is very important. The erythema carried by a good substrate is relatively uniform and has high repeatability, and can produce a stable dose-effect relationship and accurate test results after adding inhibitors. play a decisive role. [0003] Due to the unreasonable selection of the matrix, the uneven erythema and the poor repeatability of the concentration gradient make it difficult to accurately judge the irritation or antagonistic irritation detection. ...
