PEG-100 Stearate: Is It a Microplastic?

The name PEG-100 Stearate alone does not establish whether the finished product contains synthetic polymer microparticles. This entry's individual source review is pending.

A label match alone cannot determine product compliance. EU context: The EU restriction depends on polymer and particle criteria, exclusions and use. Abrasive microbeads have no transition after 17 October 2023. Otherwise, covered rinse-off cosmetics generally transition on 17 October 2027, other leave-on cosmetics on 17 October 2029, and make-up, lip and nail products on 17 October 2035. Microbeads, fragrance encapsulation and rinse-off uses have specific exceptions to those groupings. A name alone cannot establish compliance. US context: The federal Microbead-Free Waters Act targets intentionally added solid plastic microbeads in rinse-off cosmetics for exfoliating or cleansing. It is not a blanket ban on all polymers or a product safety assessment. Other applicable rules require separate checking. Other substance-specific rules are separate from the microplastic definition; this reference is not a compliance determination.

A label-name match does not measure particles, concentration, exposure or health effects. Polymer identity alone does not establish particle form or legal scope.
