Accelerated stability test for active contents in preparation for external application to skin

摘要

The present invention relates to a new accelerated test method that can significantly shorten the stability test period for an active ingredient included in a composition for external application for skin. In the accelerated test method of the present invention, an optimal condition for an accelerated test is derived, and an accelerated stability test is performed under the derived optimal condition for the accelerated test. According to the present invention, in the stability test of the active ingredient contained in the composition for external application for skin, the test period is significantly shortened compared to the prior art, so that the efficiency of product production can be greatly improved, and the prescription content standard of the active ingredient in the product composition is established It is also useful to As an example, when the stability test of dexpanthenol according to the present invention is performed, the test period can be shortened from 6 months to 46 days, and the prescription content can be determined based on the minimum effective content value of dexpanthenol.
