Problems solved by technology

The detection of arecoline in cosmetics is one of the important guarantee measures for the safety of cosmetics. At present, direct compound detection methods are mostly used. However, in practical applications, after the arecoline in cosmetics is mixed with formula ingredients, it is tested with direct There are large differences in the detection of compounds, which will affect the accuracy of the detection

Embodiment 1

[0034] According to formula and preparation process in the table, be mixed with cosmetic cream. Prepare arecoline into 50mg / 100mL propylene glycol solution, then slowly add the propylene glycol solution containing arecoline into the cream to make the final concentration of arecoline reach 50μg / g, and stir slowly under the conditions of keeping the temperature constant and the least water evaporation. Evenly, pack.

[0035] The purity of arecoline is ≥98.0% (Shanghai Bainian Dande Testing Technology Co., Ltd.).

[0036] Standard substance of the present invention is used to detect the homogeneity test of cosmetic kind arecoline:

[0037] 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 One of the bottles is used as the basic comparison point...

Abstract

The invention relates to a preparation method of a standard substance for detecting arecoline in a cosmetic. The preparation method is characterized in that a propylene glycol solution of the arecoline is mixed with cosmetic cream to form the standard substance for detecting the arecoline 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 arecoline is mixed with the cosmetic cream to form the standard substance for detecting the arecoline in the cosmetic; the standard substance is the same as that in a cosmetic sample containing the arecoline in actual use, so that detection on the arecoline in the cosmetic can accord with an application state; and the detection is relatively accurate.

Description

technical field [0001] The invention relates to a preparation method of a standard substance for detecting arecoline in cosmetics. The method is to mix arecoline with cosmetic cream through a certain technical method to form a standard substance for detecting arecoline in cosmetics. Background technique [0002] Arecoline is the main alkaloid component of areca nut and is considered to be the main component of areca nut's toxic effects. The detection of arecoline in cosmetics is one of the important guarantees for the safety of cosmetics. At present, direct compound detection methods are mostly used. However, in practical applications, after the arecoline in cosmetics is mixed with formula ingredients, it is tested with direct There are large differences in the detection of compounds, which will affect the accuracy of the detection. Compared with standard compounds, cosmetic standard substances not only have accurate measurement standards, but also have one or more sufficie...
