Problems solved by technology

The detection of aristolochic acid A in cosmetics is one of the important safeguards for the safety of cosmetics. At present, direct compound detection methods are mostly used. However, in practical applications, after mixing aristolochic acid A in cosmetics with formula ingredients, There is a big difference between detection and direct compound detection, which will affect the accuracy of detection

Embodiment 1

[0035] According to formula and preparation process in the table, be mixed with cosmetic cream. Aristolochic acid A is prepared into 32mg / 100mL propylene glycol solution, then the propylene glycol solution containing aristolochic acid A is slowly added to the cream, so that the final concentration of aristolochic acid A reaches 30 μg / g, while keeping the temperature constant Stir slowly under the condition of minimum water evaporation, and pack.

[0036] The purity of aristolochic acid A is ≥98.0% (Shanghai Bainian Dande Testing Technology Co., Ltd.).

[0037] Standard substance of the present invention is used to detect the homogeneity test of cosmetic species aristolochic acid A:

[0038] Homogeneity is the most basic attribute of standard materials. The project randomly selects n bottles of standard materials developed in accordance with the "Guidelines for Standard Sample Work (5): General Rules for Chemical Composition Standard Sample Technology" (GB / T15000.9-94), and O...

Abstract

The invention relates to a preparation method of a standard substance for detecting aristolochic acid A in a cosmetic. The preparation method is characterized in that a propylene glycol solution of the aristolochic acid A is mixed with cosmetic cream to form the standard substance for detecting the aristolochic acid A in the cosmetic. The formula of the cosmetic cream comprises a phase A, a phase B, a phase C and a phase D in percentage by weight, namely the phase A comprises 3 to 5 percent of stearate, 2 to 4 percent of alcohol and 10 to 14 percent of #26 white oil; the phase B comprises 38 to 42 percent of propylene glycol, 0.1 to 0.3 percent of carbomer and 36 to 42 percent of deionized water; the phase C comprises 0.1 to 0.3 percent of triethanolamine, and the phase D comprises 1.25 to 1.30 percent of phenoxyethanol and ethylhexylglycerin; and the concentration of the arecoline in the standard substance is 50 mug / g. The preparation method has the advantages that the aristolochic acid A is mixed with the cosmetic cream to form the standard substance for detecting the aristolochic acid A in the cosmetic; the standard substance is the same as that in a cosmetic sample containing the aristolochic acid A in actual use, so that detection on the aristolochic acid A in the cosmetic can accord with an application state; and the detection is relatively accurate.

Description

technical field [0001] The invention relates to a method for preparing a standard substance for detecting aristolochic acid A in cosmetics. The method is to mix aristolochic acid A with a cosmetic cream through a certain technical method to form a standard substance for detecting aristolochic acid A in cosmetics. Standard substance of dochlic acid A. Background technique [0002] Aristolochic acid A is a kind of nitro-containing phenanthrene organic acid, which mainly exists in Aristolochia Aristolochia plants, and has obvious nephrotoxicity. The detection of aristolochic acid A in cosmetics is one of the important safeguards for the safety of cosmetics. At present, direct compound detection methods are mostly used. However, in practical applications, after mixing aristolochic acid A in cosmetics with formula ingredients, There is a big difference between detection and direct compound detection, which will affect the accuracy of detection. Compared with standard compounds,...
