On April 12, 2021, the European Commission (EC) Scientific Committee on Consumer Safety (SCCS) published its羟基磷灰石的最终意见(纳米)。The EC asked whether SCCS considers the nanomaterial hydroxyapatite safe when used in leave-on and rinse-off dermal and oral cosmetic products according to the maximum concentrations and specifications reported, taking into account reasonably foreseeable exposure conditions. SCCS states that having considered the data provided, and other relevant information available in scientific literature, it “cannot conclude on the safety of the hydroxyapatite composed of rod-shaped nanoparticles for use in oral-care cosmetic products at the maximum concentrations and specifications given in this Opinion.” This is because the available data and information are not sufficient to exclude concerns over the genotoxic potential of hydroxyapatite (nano). The EC also asked whether SCCS has any further scientific concerns with regard to the use of hydroxyapatite in nano form in cosmetic products. The opinion states that although the particle shape of the nanomaterial considered in this opinion is reported as rod-shaped, “SCCS is aware that, depending on the manufacturing process, needle-shaped HAP nanoparticles may also be produced.” According to the opinion, the available information indicates that hydroxyapatite (nano) in needle-shaped form “is of concern in relation to potential toxicity” and “should not be used in cosmetic products.” SCCS concluded that there is a basis for concern that the use of hydroxyapatite (nano) in cosmetic products “can pose a risk to the consumer.”

欧洲委员会(EC)有要求科学意见来自健康,环境和新兴风险(Scheer)的科学委员会关于禁止可能减损的玩具中的二氧化钛安全。如果这些物质被归类为致癌,致突变或毒性,则玩具安全指令2009/48 / EC禁止使用玩具中的物质(CMR)。然而,可以在某些条件下允许使用这些物质。为允许使用类别2的CMR物质,必须由相关的科学委员会评估该物质,发现尤其是在暴露方面是安全的。另外一个条件是,在化学品(REACH)调节的登记,评估,授权和限制下,该物质不禁止用于消费物品。含有含有空气动力学直径≤10微米(μm)的粉末形式的二氧化钛已经被吸入被归类为致癌类别2。

舍尔有呼吁科学信息上:

  • 玩具中使用的二氧化钛的化学和物理规格;
  • 玩具中使用的颜料级二氧化钛的尺寸分布;
  • The migration or release of titanium dioxide from toys; and
  • 对玩具中使用的二氧化钛进行曝光测量。

提交为期April 28, 2021。The call for information will remain open after this date, however, and additional studies (例如。如果需要,截止日期未完成的持续研究和研究)可以在稍后阶段传递给工作组。

EC问Scheer:

  • To review the available data on the use of titanium dioxide leading to inhalation exposure in particular in toys and toy materials; and
  • 为了评估玩具和玩具材料中二氧化钛的用途,鉴于识别的曝光,鉴于致癌类别的二氧化钛的分类,可以被认为是安全的。应说明安全玩具和玩具材料betway官方网站。

On March 4, 2021, the French Agency for Food, Environmental and Occupational Health and Safety (ANSES)宣布它推荐八小时的职业曝光限制(OEL)每立方米0.80微克(μg/ m3二氧化钛纳米粒子。根据ANSES, compliance with this value “should help prevent lung inflammation, an effect that occurs at the lowest exposure concentrations.” Due to the lack of available data on the immediate or short-term effects of titanium dioxide nanoparticles, in accordance with its methodological guide, ANSES states that it also recommends not exceeding the concentration of 4.0 µg/m3over a 15-minute period. Compliance with this value should help limit the size and number of exposure peaks over the working day, according to ANSES.

ANSES notes that an expert appraisal on the assessment of methods for measuring titanium dioxide nanoparticles in air is currently under way. ANSES states that this will determine which method(s) to use to measure titanium dioxide nanoparticle concentrations in air in view of the OELs it recommended. In addition, ANSES states, the studies it requested when assessing titanium dioxide under the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulation “should enable these values to be further refined.”
