用可疑化妆品对化妆品皮炎作斑贴试验的研究

Patch Testing of Cosm etic Derm atitis Using Suspected Cosm etics

为了研究用化妆品进行斑贴试验时所需浓度，探讨用患者使用过的可疑化妆品进行斑贴试验在诊断化妆品皮炎中的应用价值，将各种化妆品以不同浓度对３５例健康者，３８例非接触性皮炎湿疹类患者进行斑贴试验。然后用患者各自的可疑致敏化妆品对６２例化妆品皮炎患者进行斑贴试验。结果：初步认为护肤类膏剂、唇膏、护发类发乳、头油、摩丝等类产品可用原物进行斑贴试验，染发剂、清洁类香皂、护发类油用２％，清洁类香波用２％和５％，冷烫精、指甲油、香水用５％或１０％。可疑化妆品斑贴试验的阳性率为９５．１６％。本研究表明：用可疑化妆品作斑贴试验时，不同类型的产品，其斑贴试验浓度并不相同，用患者的可疑化妆品进行斑贴试验是诊断化妆品皮炎的重要手段。这项研究为进一步研究我国化妆品皮炎标准筛选系列抗原提供了必要资料。

In order to study on the properconcentrations for patch test(PT),and the availability of PT w ith the suspected cosm etic products used by the patients,PT ofvarious cosm etic products w as per- form ed on 35 healthy subjects and 38 patients w ith non-contactderm atitis and non-eczem a by using dif- ferent concentrations of cosm etic products and their vehicles in cosm etic products.In 62 patients w ith cosm etic derm atitis PT w as done using their ow n suspected causative cosm etic products.The results show ed thatm ost products could be tested “w ith originalproducts”,w ithout dilution,such as skin care products(cream ),lipsticks,hair care products(hair cream ,hair oil,m ousse),others had to be diluted, such as hair dyes,hotoiland soap,to 2% solution,sham poos to 5% solution,perm anent-w ave solutions and perfum es to 5% or 10% in distilled w ater,nailvarnish to 5% or 10% in acetone.The totalpositive rate of PT by using suspected cosm etics w as 95.16% .Our results indicate that PT concentrations and vehicles vary w ith different products in suspected cosm etics,PT of the suspected causative cosm etic products is an im portant m eans for the diagnosis of cosm etic derm atitis.Our study provides necessary data for the further study ofChinese standard cosm etic screening series allergens for PT.
