EU proposes restrictions on medium chain Chlorinated paraffins (MCCP)
After comprehensive evaluation, the Risk Assessment Committee (RAC) and the Socio Economic Analysis Committee (SEAC) under the jurisdiction of ECHA of the European Chemical Administration proposed the restrictions on MCCP (medium chain Chlorinated paraffins) in Annex XVII of REACH Regulation. The deadline for consultation of this proposal is August 14, 2023, as follows:
Molecular formula
Linear chloroalkanes with the following Molecular formula:
C14H30-yCly, where y can be taken as 3-14
C15H32-yCly, where y can be taken as 3-15
C16H34-yCly, where y can be taken as 3-16
C17H36-yCly, where y can be taken as 3-17
Restrictions
1. The total concentration of chlorinated alkanes listed in column 1 in substances, mixtures, and articles [equal to or greater than 0.1% (w/w)] shall not be placed on the market.
The first paragraph shall come into effect two years after the restriction comes into effect.
3. Paragraph 1 does not apply to items that are already in use and second-hand items that were ultimately used in the EU before the [Effective Date].
4. The first paragraph does not apply to reference materials and standards used for analytical purposes.
5. Within three months after the restriction takes effect, ECHA shall publish and maintain an indicative list on its website identifying the target substance, which describes substances that may contain chloroalkanes listed in column 1.
6. Within six months after the restriction takes effect, suppliers containing the chloroalkanes listed in column 1 or the substances mentioned in paragraph 5 should summarize and identify the substances listed as PBT and/or vPvB, unless they can prove to the competent authority that the overall maximum concentration of chloroalkanes listed in column 1 is [less than 0.1% (w/w)] by providing the following information:
(i) The overall highest concentration level of chloroalkanes listed in column 1). The highest concentration level should be determined using representative batches (usually 5 batches) produced by the same manufacturer based on the same technical specifications. This level should be determined using validated analytical methods and statistical calculations.
(ii) A description of the analytical method used and the results obtained to obtain the overall highest concentration level mentioned above.
7. Within 6 months after the restriction takes effect, suppliers shall notify their downstream users and customers when placing chlorinated alkanes in the market containing concentrations equal to or greater than 0.1% w/w as listed in column 1 or paragraph 5
(i) The total content of chlorinated alkanes in the first column, as well as appropriate risk management measures and operating conditions, to minimize the release and exposure of chlorinated alkanes listed in the first column.
8. Within 7 years after its entry into force, as an exemption, the first paragraph does not apply to substances placed on the market as extreme pressure additives in oil-based metal working fluids as defined in DIN 51385
9. As an exemption, the concentration limit specified in paragraph 1 shall not apply to mixtures listed in paragraph 8 as oil-based metalworking fluids for a period of 7 years after their entry into force.
About MCCP
MCCP has the characteristics of PBT (persistence, Bioaccumulation, toxicity) and/or vPvB (strong persistence, strong Bioaccumulation), which will cause serious impact on human health and ecological environment.
Main uses of MCCP
1. PVC
Mainly used for producing PVC compounds for PVC cables and sheaths;
Main functions: flame retardant, auxiliary plasticizer.
2. Adhesives and Sealants
Mainly used for polyurethane and polysulfide based sealants, for sealing cracks or interfaces;
Main functions: plasticizer, flame retardant.
3. Rubber
Used for specific types of general rubber products that require flame retardancy (such as rubber conveyor belts and rubber pipes used in mining and underground activities);
Main functions: plasticizer, flame retardant.
4. Metal working fluid
Added to certain types of metal working fluids (such as pure oil) for processing certain metals under extreme conditions;
Main function: Extreme pressure additive.
5. Paint and coating
Special solvent based coatings (such as protective coatings and ship coatings), expansion coatings, flame retardant coatings, and anti fouling coatings (as co formulations of bactericidal products);
Main functions: flame retardant, Plasticizer.
6. Leather
Used for leather processing (re greasing of leather);
Main functions: softener, leather waterproof.
7. Mixture (lubricating oil)
Specific lubricants
