注意:对于无法使用上述任一证据类型的原料和/或风险物质,应按照《化妆品安全评估技术导则(2021年版)》要求的评估程序(1.危害识别 > 2.剂量反应关系评估 > 3.暴露评估 > 4.风险特征描述)进行评估证明其安全性。

全身暴露量(SED)=日均使用量 × 驻留因子 × 成分在配方中百分比 × 经皮吸收率 ÷ 体重
安全边际值(MoS) × 不确定因子(UF)= 未观察到有害作用的剂量(NOAEL/BMDL)÷ 全身暴露量(mg/kg·bw/day)
在通常情况下, 当MoS ≥ 100 × 不确定因子(UF)时,可以判定是安全的。

Assessment conclusions by international authoritative cosmetic safety assessment agencies:

ABSTRACT: EDTA (ethylenediamine tetraacetic acid) and its salts are substituted diamines.HEDTA(hydroxyethyl ethylenediamine triacetic acid) and its trisodium salt are substituted amines. These ingredients function as chelating agents in cosmetic formulations. The typical concentration of use of EDTA is less than 2%, with the other salts in current use at even lower concentrations. The lowest dose reported to cause a toxic effect in animals was 750 mg/kg/day. These chelating agents are cytotoxic and weakly genotoxic, but not carcinogenic. Oral exposures toEDTAproduced adverse reproductive and developmental effects in animals. Clinical tests reported no absorption of an EDTA salt through the skin. These ingredients are likely, however, to affect the passage of other chemicals into the skin because they will chelate calcium. Exposure to EDTA in most cosmetic formulations, therefore, would produce systemic exposure levels well below those seen to be toxic in oral dosing studies. Exposure to EDTA in cosmetic formulations that may be inhaled, however, was a concern. An exposure assessment done using conservative assumptions predicted that the maximum EDTA dose via inhalation of an aerosolized cosmetic formulation is below that shown to produce reproductive or developmental toxicity. Because of the potential to increase the penetration of other chemicals, formulators should continue to be aware of this when combining these ingredients with ingredients that previously have been determined to be safe, primarily because they were not signiŽ cantly absorbed. Based on the available data, the Cosmetic Ingredient Review Expert Panel found that these ingredients are safe as used in cosmetic formulations.lniojgnic

CONCLUSION: On the basis of the information included in this report, the CIR Expert Panel concludes that EDTA, Calcium Disodium EDTA, Diammonium EDTA, Dipotassium EDTA, Disodium EDTA, TEA-EDTA, Tetrasodium EDTA, Tripotassium EDTA, Trisodium EDTA, HEDTA, and Trisodium HEDTA are safe as used in cosmetic formulations.
