An alternative to PVC and phthalates in high density plastisol prints.

Abstract

PVC and phthalates have been extensively used for plastisol prints in textile applications. This case story describes the substitution of PVC and phthalates by silicon prints.

Substituted substance(s)

  1. Polyvinyl chloride (PVC)

    CAS No. 9002-86-2 EC No.  Index No. 
  2. Dibutyl phthalate

    CAS No. 84-74-2 EC No. 201-557-4 Index No. 607-318-00-4
  3. Di(2-ethylhexyl) phthalate

    CAS No. 117-81-7 EC No. 204-211-0 Index No. 607-317-00-9
  4. Diisononyl phthalate

    CAS No. 28553-12-0 EC No. 249-079-5 Index No. 
  5. Di-''isodecyl'' phthalate

    CAS No. 26761-40-0 EC No. 247-977-1 Index No. 

Alternative substance(s)

  1. Dimethyl siloxane, hydrogen terminated

    CAS No. 70900-21-9 EC No.  Index No. 
  2. Dimethyl methylhydrogen siloxane

    CAS No. 68037-59-2 EC No.  Index No.

Hazard assessment

Many of the substituted phthalates are classified as toxic to reproduction and are on the “Hazardous substance database” according to SUBSPORT Screening Criteria (SDSC). The alternatives have no official classification and are not on the SDSC.

Substitution description

PVC is a widely used thermoplastic polymer. It can be made softer and more flexible by the addition of plasticizers, the most widely-used being phthalates. In this form, it is used in clothing and accessories. It is commonly used in coats, jackets, aprons and bags. The global phase-out of PVC is advocated because it is claimed that dioxin is produced as a byproduct of vinyl chloride manufacture and from incineration of waste PVC in domestic garbage.

Phthalates are a class of organic compounds added to plastics to increase flexibility. In textiles and apparel, phthalates can be associated with flexible plastic components, trims, screen and plasticol prints. Several phthalates are known to be reprotoxic and can cause birth defects and changes in hormone levels.

G-Star is continuously striving towards sustainable solutions and achieving the goal of zero discharge of hazardous chemicals in its supply chain. One of these goals is completely phasing out PVC and phthalates. Intensive investigations using accredited third party testing institutes showed that part of the prints used on products did not meet the requirements as laid down in G-Star’s Restricted Substances List (RSL). With the cooperation of the suppliers a broad research program was initiated. This resulted in a successful  replacement of PVC and phthalates in High Density Plastisol prints by High Density Silicon prints. The substitution process started in March 2012 and is ongoing in the global supply chain,  in which the company works  closely with suppliers, technicians and ink suppliers. Research is ongoing to find suitable ink and paste for the different product groups  in the supply chain.

Dimethyl siloxane, hydrogen terminated and dimethyl, methyl hydrogen siloxane can replace phthalates without major process changes. A number of phthalates are listed on the Candidate list for SVHC, Annex XIV the Authorisation list and/or in Annex XVII REACH.

Case/substitution evaluation

This case story describes the phaseout of PVC and its associated phthalates in textile plastisol prints. Silicon prints were found suitable as substitutes. The mentioned siloxanes have no official classification nor are on the SDSC.
