Embodiment Construction

[0015] For further illustrating the present invention, specifically illustrate in conjunction with following examples:

[0016] 1. Sample pretreatment

[0017] Cloth and sticker toys: Cut the toy samples into pieces with scissors to less than 5mm×5mm, and mix well. Accurately weigh 1.0g sample (accurate to 1mg), place it in a 50mL Erlenmeyer flask (or 50mL stoppered test tube), add 20mL acetone as the extraction solvent, stopper the bottle tightly, seal it with a parafilm, and extract by ultrasonic at room temperature 20min. The supernatant in the extract was sucked, passed through a 0.45 μm microporous PTFE filter membrane, and then subjected to gas chromatography-ion trap mass spectrometry.

[0018] Plastic toys: crush the toy sample with a cutting grinder or cut it with scissors, weigh 1.0g sample into a 50mL conical flask, add 10mL reagent to dissolve (ABS plastic is dissolved in acetone, PS plastic is dissolved in dichloromethane, PVC plastic dissolved in tetrahydrofur...

Abstract

The invention relates to a method for simultaneously determining residual quantities of sixteen sensitized aldehyde and ketone perfumes in a toy, and firstly discloses a method for simultaneously determining the residual quantities of the sixteen sensitized aldehyde and ketone perfumes consisting of 5-methyl-2,3-hexanedione, trans-2-heptenal, trans-2-hexenaldimethylacetal, citral, cinnaldehyde, hydroxycitronellal, benzalacetone, 2,4-dihydroxy-3-methylbenzaldehyde, alpha-isomethylionone, lilial, 6,10-dimethyl-3,5,9-undecatrien-2-one, 4-(4-methoxyphenyl)-3-butylene-2-one, alpha-amyl cinnamic aldehyde, lyral, 1-(4-methoxyphenyl)-1-pentene-3-one, and hexylcinnamaldehyde in the toy to fill the technological blank. The method which allows cloth toys, paster toys, and plastic toys (the ABS material, the PVC material and the PS material) to be detected has the advantages of wide coverage and strong applicability. The method which adopts the ion trap-mass spectrum in a qualitative and quantitative secondary mass spectrum MS / MS mode has a good qualitative and quantitative capability to complex matrix toy samples.

Description

technical field [0001] The invention relates to a detection technology, in particular to a method for simultaneously measuring the residual amount of 16 kinds of aldehydes and ketones allergenic fragrances in toys. Background technique [0002] Fragrances or flavoring agents are often added during the production of toys to give them a scent and thereby increase their appeal to children. Flavors and fragrances are usually composed of dozens to hundreds of organic compounds with aromatic odors. Not all of these compounds are safe and harmless, and some substances have strong allergens, so-called allergenic fragrances. Relevant studies have shown that at least 1-2% of people will develop allergic symptoms after exposure to fragrance substances, such as asthma and other respiratory diseases, headaches, mucosal symptoms, itchy dermatitis, etc. When toys containing allergenic substances are played by children, these substances will enter the body through skin, inhalation, saliva,...
