Problems solved by technology

However, the current analytical methods for cosmetics all use ordinary ultraviolet detectors. Since the specimen may contain many components, which interfere with the substance to be tested, other interfering substances will have a great impact on the target substance, and it is difficult to completely separate and easily cause false positives. Sex results
The existing analysis methods for antioxidants in cosmetics are mainly based on ultraviolet detectors, and the samples tested are all samples with few ingredients. When the samples contain a large amount of other ingredients, the antioxidants are completely contained in other impurities. , cannot be detected at all, and if the impurity is removed by pre-treatment, first, there is no good pre-treatment method, and second, it will take a lot of time to establish a pre-treatment method for different samples, which will be very difficult.

Embodiment 1

[0037] Using the electrochemical analysis method of antioxidants in cosmetics according to the present invention, several types of cosmetics were analyzed.

[0038] Experimental steps:

[0039] It is taken from some whitening and anti-aging cosmetics, some perfumes, and some hair dyes.

[0040] The above-mentioned cosmetics are used as inspection products to detect whether they contain pre-detected substances.

[0041] Firstly, the sample is pretreated, and the sample that needs to use solvent is degassed by ultrasonic.

[0042] Measure 5g of the sample containing AA2G, dissolve it in a 50ml volumetric flask with methanol, and extract it ultrasonically for 15min. After 15min, filter the test solution with a syringe membrane filter (0.45μm) and get 200μL into the sample bottle to be tested.

[0043] Measure 5g of the sample containing VC ethyl ether, dissolve it in a 50ml volumetric flask with methanol, and extract it ultrasonically for 15min. After 15min, filter the test so...

Abstract

The invention provides a method and a system for electro chemical analysis of an antioxidant in cosmetics. The method for electro chemical analysis of the antioxidant in cosmetics comprises the following steps: performing pretreatment on a cosmetic sample in advance; and detecting the cosmetic sample by an electrochemical detector, and accurately detecting an antioxidant component under a complexbackground of the cosmetics.

Description

technical field [0001] The method relates to an analysis method of antioxidants in cosmetics, in particular to an electrochemical analysis method and analysis system of antioxidants in cosmetics. Background technique [0002] The ingredients used in cosmetics must not only have good usefulness (function) and usability (use feeling), but also be harmless to the human body and be able to be stored for a long time, that is, have high stability. The raw materials of cosmetics can be roughly divided into: base raw materials necessary for cosmetics; pharmaceutical raw materials added to increase physiological activity, effect and function; raw materials added to maintain product quality; raw materials that impart sensory characteristics such as color and fragrance. [0003] Among them, in order to ensure the quality of cosmetics, antioxidants need to be added, but excessive antioxidants will damage human health. Therefore, it is necessary to establish a highly selective and accur...
