Low concern Assessed 11 Apr 2026 · 5 months ago

Assessed from the published materials and ingredient list.

This does not prove that zero microplastic or nanoplastic particles are present or could ever be released.

Microplastic Status

Based on available ingredient data, Kilner Clip Top Glass Jar 1L does not contain known microplastic ingredients. Materials used include soda lime glass, stainless steel clip, rubber seal. This assessment is based on publicly available product information and ingredient databases.

How we assess products

We work from published information; we do not lab-test, and a verdict here is never a claim that we have.

Low concern means the published materials we assessed show no known microplastic ingredient and no material microplastic concern. It does not mean:

  • Not proof that no microplastic or nanoplastic particles are present or released — analytical methods have lower size limits, and nanoplastics largely escape detection.
  • Not elimination of background exposure, which indoor dust and diet may dominate anyway.
  • Not proven health safety — current science cannot substantiate that for any product.
  • Not a general environmental or sustainability endorsement.
