Abstract
The invention relates to a method for detecting mercury in cosmetics. The method comprises the following steps of: firstly, adding cosmetics to be detected in water, preparing into a cosmetics water solution; then preparing three parts of detection reagents; finally, separating the cosmetics water solutions prepared in the step (1) into three parts, respectively adding in the three parts of detection reagents, observing the change of the color of the water solution of the cosmetics; and if the three parts of cosmetic water solutions have characteristic chromogenic reactions, judging that the mercury is contained in a sample. Whether the mercury is contained in the cosmetics or not is judged by adopting a manner that three reagents simultaneously develop, thus the method is more accurate in comparison with a method of judging by only adopting two reagents, and the phenomenon of false negative usually occurring in a judging process caused by only adopting the two reagents is avoided.
Description
Technical field
The invention belongs to cosmetics safety detection field, be specifically related to the detection of Mercury In Cosmetics.
Background technology
Mercury is a kind of high toxicity heavy metal contaminants, also be unique heavy metal existing with liquid form at normal temperatures, mercury can carry out human body by alimentary canal, respiratory tract or skin and mucosa, and people's brain, kidney and body cell etc. are all caused to damage, also can cause that arthritis is even carcinogenic.Mercury is extensively present in the nature media such as atmosphere, water and soil, at present, along with industrial expansion, the burning of mineral fuel and solid waste, the use of mercury in chlorine industry and electrical equipment industry, the pollution of mercury is day by day serious at present, the mercury poisoning of continuous several times generation in recent years event, as the mercury poisoning event of the Mad Hatter's disease event of 20 middle of century Japan and U.S.'s generation.
Cosmetics are requisite skincare products during people live, and along with countries in the world economy and cultural development and progress, people are more and more to the demand of cosmetics, require also more and more higher.The negative ion of tyrosinase in the replaceable skin of the heavy metals such as mercury, this enzyme is lost activity, thereby melanin is gone down, make skin-whitening, make the skin gloss that becomes delicate, hair pore shrinkage, simultaneously also can anti-acne, nti-freckle, although these effects are temporary transient, but many illegal manufacturers, in order to make its product have quick whitening effect, to strive for more consumer, try to gain more interests, just the mercurous compound of illegal interpolation in the cosmetics of its production, and the mercury content adding is conventionally at 1-2.5%.Long term consumer is used the cosmetics of this content overproof, can produce larger injury to health.
Because the heavy metals exceeding standards such as Mercury In Cosmetics have larger impact to human body, < < cosmetics health standard > > (version in 2007) has done clear and definite restriction to the content of the heavy metals such as Mercury In Cosmetics, and wherein the content of mercury must not surpass 1 ppm.At present, in China < < cosmetics health standard > >, the method for inspection of regulation mercury comprises the instrument detection methods such as cold-vapour atomic absorption method and atom fluorescent luminosity method, although these method testing results are accurate, highly sensitive, but when these instruments detect, sample pre-treatments is loaded down with trivial details, in testing process, produce a large amount of harmful gases, environment has also been caused to larger pollution, and detecting instrument is valuable, field test is also subject to significant limitation, therefore, cannot meet supervision department's requirement that on-the-spot examination at random checks to cosmetics.
Summary of the invention
The object of the invention is to for deficiency of the prior art, a kind of detection method that can detect rapidly the content of Mercury In Cosmetics simple to operate is provided.
Technical scheme of the present invention is as follows:
A detection method for Mercury In Cosmetics, comprises the steps:

(3) the cosmetics aqueous solution making in step (1) is divided into three parts, adds respectively first part to detect reagent, second part of detection reagent and the 3rd part of detection reagent, observe the variation of the aqueous solution color of cosmetics; As feature chromogenic reaction all appears in three parts of cosmetics aqueous solution, mercurous in judgement sample.
Preferably, in the cosmetics aqueous solution described in step (1), the concentration of cosmetics is 0.1 ~ 0.3g/ml.
Preferably, the described water of step (1) is purified water.
Preferably, the addition of described alkyl polyoxyethylene ether is 5-10ml.
Preferably, described acid solution is hydrochloric acid solution, and concentration is 0.8-1.2mol/L, and the amount adding is 5ml.
Preferably, the described reagent that can produce sulphion is sodium sulfide solution or thioacetyl amine aqueous solution, and the concentration of described sodium sulfide solution or thioacetyl amine aqueous solution is 0.3 ~ 1.0mol/L, and addition is 5-10ml.
Preferably, the described reagent that can produce iodide ion is IodineSodium Solution or liquor kalii iodide, and described IodineSodium Solution or the concentration of liquor kalii iodide are 0.3-0.8mol/L, and addition is 5-10ml.
Preferably, described stannous chloride dosage enters for 0.5g, and in described step (2), the heat time is 10min, and heating-up temperature is 60-80 ℃.
Preferably, described copper sheet quality is 0.5-2g.
Preferably, described chromogenic reaction is specially in the cosmetics aqueous solution that adds first part of detection reagent and occurs black or grey; Add in second part of cosmetics aqueous solution that detects reagent and occur salmon pink precipitation; Add copper sheet surface color in the 3rd part of cosmetics aqueous solution that detects reagent to become silvery white.
Compared with the existing technology, beneficial effect has in the present invention:
1. the present invention adopts three kinds of reagent to develop the color to judge in cosmetics whether contain mercury simultaneously, more accurate than the method only judging with two kinds of reagent, has prevented from only adopting the false negative phenomenon often occurring in two kinds of reagent deterministic processes.
2. the present invention compares with the detection method of traditional cosmetics mercury, does not need to use exact instrument, only needs reagent can complete testing process, testing result judgement only needs to observe change color, and simple to operate, testing cost is low, can Site Detection, meet actual detection demand.
3. the present invention compares with the detection method of traditional cosmetics mercury, does not produce harmful gas, environmentally safe.
4. in the present invention, in first part of cosmetics aqueous solution, add can produce in the reagent of sulphion and the 3rd part of cosmetics aqueous solution to add stannous chloride, copper sheet, this two group reaction also can other heavy metal ion of preliminary judgement as existence plumbous, arsenic.In the present invention, in cosmetics reactant aqueous solution liquid, all add hydrochloric acid, can avoid the interference of ferric ion to the experiment of this group.The present invention has higher sensitivity, is applicable to the conventional sense of cosmetics supervision department to Mercury In Cosmetics.
