Harsh Extraction

For many years, trace chemicals have been monitored by using state of the art harsh extraction methods in laboratories like SGS.

Those methods help providing with an intrinsic quantification of substances for who may need to respond current regulations, internal blacklists and volunteer labels. Often used as a worst-case approach to further investigation, such method helps as well by its replicability to both materials and finished products.

  • PE films
  • Elastics
  • Glue

Finished products:

  • Baby diapers
  • Feminine hygiene: pads, panty liners, tampons
  • Incontinence pads and liners
  • Tissue (toilet paper, handkerchiefs)
  • Wipes
  • Cottons (pads, swabs, balls, zig-zag)
  • Plaster

Targets and Limits

Based on:

  • OEKO-TEX® STANDARD 100 interpretation
  • Food contact

Added Value

  • Works with all type of products (finished or raw)
  • Intrinsic quantification
  • Used for monitoring
  • Responds to current internal blacklists and volunteer labels (OEKO-TEX®, GOTS, BLAUER ENGEL...)

Additional services

Whatever substances are detected above our quantification limits, SGS can assist with toxicological expertise on request to assess the exposure, calculate the safety margins and write a report to conclude on the safety of the product.
