欧盟关于物质和混合物分类,标签和包装的法规(EC)No1272/2008,通常称为CLP法规，近期正式将二氧化钛列入2类致癌疑似物进行监管，2021年9月前为法规执行过渡期，请相关企业及时跟进。
但并不是把所有形式的TiO2列入上述法规的监管，只是下面这种情况，主要涉及影响的行业是涂料、油墨和化妆品等。
The classification as a carcinogen by inhalation applies only to mixtures in powder form containing 1 % or more of titanium dioxide which is in the form of or incorporated in particles with aerodynamic diameter ≤ 10 μm.’;
检索该法规全文，总共出现13次“titanium dioxide”词。其中下面这段话提到了TiO2的安全性问题和法规的由来：
(5) In its scientific opinion of 14 September 2017 on the substance titanium dioxide, RAC proposed to classify that substance as carcinogen category 2 by inhalation. As titanium dioxide-induced lung carcinogenicity is associated with inhalation of respirable titanium dioxide particles, retention and poor solubility of the particles in the lung, it is appropriate to define respirable titanium dioxide particles in the titanium dioxide entry. The deposited particles,but not solutes of titanium dioxide, are assumed to be responsible for the observed toxicity in the lung and subsequent tumour development. In order to avoid unjustified classification of non-hazardous forms of the substance, specific notes should be laid down for the classification and labelling of the substance and mixtures containing it. In addition, as some hazardous dust or droplets could be formed during the use of mixtures containing titanium dioxide, it is necessary to inform the users of the precautionary measures that need to be taken to minimise the hazard for human health.
该法规要求当组合物中TiO2颗粒物含量等于大于1%时，或尺寸范围在规定范围内时，产品标签需要进行相关注明提醒。标签示例与适用情况如下：
‘2.12. Mixtures containing titanium dioxide The label on the packaging of liquid mixtures containing 1 % or more of titanium dioxide particles with aerodynamic diameter equal to or below 10 μm shall bear the following statement: EUH211: ‘Warning! Hazardous respirable droplets may be formed when sprayed. Do not breathe spray or mist.’ The label on the packaging of solid mixtures containing 1 % or more of titanium dioxide shall bear the following statement: EUH212: ‘Warning! Hazardous respirable dust may be formed when used. Do not breathe dust.’ In addition, the label on the packaging of liquid and solid mixtures not intended for the general public and not classified as hazardous which are labelled with EUH211 or EUH212, shall bear statement EUH210.’
