REACH and paper chemicals

REACH and paper chemicalsAssessment based on 1st reading of European Parliament

•Paper chemicals from regulatory point of view

•REACH and R&D

•Some examples of products

•Future


Paper chemicals

• Most are HPV–substances (> 1000 t per year)– Even special additives > 1 t per year

• A number of nature based chemicals– Modified– Annex II and III – content and interpretations

• Complicated reaction mixtures and poorly soluble substances– Testing

• Many substances have long history of use, old test data – not under GLP

• NLPs, No Longer Polymers, e.g. emulsifiers

• A number of functional polymers– Many starting substances will need authorisation

• Time from idea to market will be longer

• Paper machines are sensible for changes in products

• A number of customized products


R&D - Pulp and paper chemicals

• Many additives and process chemicals, e.g.

• Solvents• Initiators, catalysts• Chain transfer agents• Emulsifiers, surface active agents• Antioxidants• Plasticizers• Stabilizers• Release agents• pH Regulators• Stripping chemicals• Defoamers• Biocides


REACH – Something to gain

+ R&D and PPORD+ Longer than current PORD 5+10 years + Only one application dossier, not separately in every MS:

Agency Same fee and equal opportunity

+ Volume versus application

+ Categories and read across+ Possibility to play around the molecules and find/use

”new” molecules without full testing dossier+ Annex II?+ Practice?

+ More data publicly available

+ Learning from each other?


REACH – Concerns for paper chemicals• List of available chemicals will be shorter than

today– EINECS: 100 116 entries– ELINCS: ~5000– + NLP:s, No Longer Polymers– Future: ~ 30 000 +/- xxxx?

• Practice– Interpretations– Annex II and III– Exposure based waiving…

• OSOR– Workability


REACH – Concerns for paper chemicals

• Chemical Safety Assessment and Chemical Safety Report (>1 t/y) – Risk Management Measures included– Covers also marine environment– Exposure scenarios

• Paper making and recycling– Exposure and use categories– Communication in safety data sheets

• Authorisation may require a lot of resources– Substitution and research in order to find alternatives => ”Defensive R&D”– Socio Economic Analysis / Methodology – Time limited (5 years)– Can be opened by third party intervention– Many monomers and other starting substances for

polymers used by paper industry will require authorisation • e.g. acrylamide, acrylonitrile, butadiene,

epichlorohydrin…


How to find alternative substances?

Active structural groups = reactive groups

Other approval processes may take years to complete, e.g. food contact compliance

Substances with long history of use are known

– Test results, exposure data exist– Technical performance known– Availability

• Production processes and facilities • Raw materials

– Reasonable price


How to find alternative substances?

•Possible change in the composition of paper chemicals =>

– Literature & desktop research– Laboratory trials– Pilot trials – Production trials– Application trials: by the producer of the chemical

+ customer pilots– Mill trials

Easily a couple of years and yyy yyy € or y yyy yyy €


REACH requires resources

• All functions of a company will be effected– Purchasing– R&D, e.g. laboratories

• Substance identity, impurities, side reaction products etc.• Physico chemical properties• Registration and authorisation dossier and CSR

> Different uses • Dosage, content/residues in intermediates and final

products, exposure measurements> Emission/Effluent measurements

• Air, water, waste water treatment plants (including sludge), soil, sediment

> Recycling and disposal…• R&D in future more defensive than real R&D

– Production– Sales– Administration

• ”REACH Competence Centers” (including ”office chemists”)• IT…


REACH AND PAPER CHEMICALS - Examples

• Styrene acrylate based polymeric size

– Polymers exempted from REACH for the time being but new Safety Data Sheets, SDSs for the products have to be prepared

– Monomers and other starting substances have to be registered, HPV chemicals => Chemicals Safety Report, CSR and new SDSs

• Own production and importation but EU-RA, ICCA Initiative and EPA HPV program data exist for main monomers

• Specific monomers, initiators, emulsifiers, pH regulators, defoamers etc.

> Make sure that they will be available, PBT or vPvB… or prepare for defensive R&D

> Possible data gaps…

• Food contact approvals exist => this use is exempted from CSR

• Styrene possible endocrine disruptor - authorisation?


PAPER CHEMICAL EXAMPLES

• Calcium distearate

– Annex II – pure!

• Annex II: ”Substances commonly found in foodstuffs, such as citric acid, sugar, oils, fatty acids, etc.”

– Adipic acid (E 355), citric acid (E 330)

– Casein?

– Fatty acids and their derivatives as deinking chemicals?


REACH & paper chemicals

• Details and interpretations still open

• Basic volume chemicals - bulk– No remarkable changes foreseen yet– Some additives may be ”lost” which may cause additional

workload and cost effects

• Specialty chemicals– Some pressure on further testing

• Long term effects• Testing problems

• Substitution is very difficult


REACH - Cooperation of mills and chemicals’ suppliers

Management of chemical know how• ERP systems• Data per substance versus products• Communication

– Questionnaires and safety data sheets

Registration, evaluation and authorisation

• Substance information: Suppliers!

• Chemical Safety Reports

– Help from customers will be needed– Exposure scenarios– Compare to current EU Risk Assessment


REACH – Future

• Resources?• Prices • New type of business with

– REACH compliant chemicals – IPR

• Data ownership• Registration and authorisation dossiers and numbers

But paper will be made and paper chemicals will be manufactured and developed even when REACH is in force…
