Are Birkenstock Care Essentials certified?


Birkenstock Care Essentials are all either COSMOS Natural or COSMOS Organic certified. This ensures that our products meet strict standards for:

  • Promoting organic agriculture
  • Respecting biodiversity
  • Using resources responsibly
  • Employing clean manufacturing practices that prioritize human and environmental health

To achieve COSMOS Organic certification, at least 20% of any leave-on product (excluding water) must be organic, and at least 95% of the organic ingredients must meet organic farming standards.


Our products are not only made with 100% natural ingredients, they're completely free from paraffin, silicones, parabens, synthetic fragrances or pigments, PEGs, animal testing and genetic engineering.
