Embodiment 1

[0026] Example 1 is the optimal film-forming gel. The products (see Table 1) obtained by the formula of Example 1 are added one by one into the small chamber of the spot tester, and after the back is closed and applied for 24 hours, the results are observed 24 hours after the application , figure 1 It shows that the erythema caused by Example 1 is very uniform, erythema occurs in all 10 small chambers, and the erythema is evenly seen in the small chamber and the small chamber. The inventor conducted the same experiment with the products prepared in Examples 2-6, and compared with the comparative examples, they all had good repeatability and uniformity.

Abstract

The invention discloses a gel composition, patch and application thereof. The gel composition of the present invention includes a film former, a thickener, a penetration enhancer and a solvent. The use of the gel composition in patch products can solve the problem of unstable results of antagonistic stimulus patches and reduce misjudgment of results caused by unstable stimulus modeling.

Description

technical field [0001] The invention specifically relates to a gel composition, patch and application thereof. Background technique [0002] The choice of substrate for product irritation or antagonistic stimulation test is very important. The erythema carried by a good substrate is relatively uniform and highly repeatable, and it plays a role in whether the addition of inhibitors can produce a stable dose-effect relationship and obtain accurate test results. decisive role. [0003] Patch test has low accuracy due to factors such as matrix and individual differences. In the prior art, due to unreasonable choice of matrix, uneven erythema and poor repeatability of concentration gradient, it is difficult to accurately judge the detection of irritation or antagonistic irritation. At present, the use of closed human body patch for SDS antagonistic stimulation test uses more water agents as substrates, and the erythema produced by water agents carrying SDS is not uniform, and th...
