Materials, packaging, certification

Specifics, not adjectives

Environmental language is cheap and mostly interchangeable. What follows is what our products are made of, how they are packed, and which outside bodies have reviewed them — with the criteria each one actually applies.

Third-party certification

Two programs apply to OHM Wash. Each is run by an outside body with published criteria, and each covers a specific and limited thing.

U.S. EPA Safer Choice certification mark: Meets U.S. EPA Safer Product Standards, epa.gov/saferchoice

EPA Safer Choice

Run by the U.S. Environmental Protection Agency. Every ingredient in OHM Wash has been reviewed against the EPA’s Safer Chemical Ingredients criteria, and the program requires this website to publish the complete ingredient list with CAS numbers — which is why the ingredients page exists.

USDA Certified Biobased Product label, product 55 percent

USDA Certified Biobased

Run by the U.S. Department of Agriculture. The label reports the percentage of a product made from renewable biological material, measured by a standard test method rather than self-declared. OHM Wash is certified at 55%.

Certification marks shown on packaging are the property of the bodies that issue them and are used under the terms of those programs.

OHM Wash

  • Twelve ingredients, all published with CAS numbers on the ingredients page.
  • Contains biodegradable surfactants. We hold an OECD 301B CO2 evolution test report on file, carried out on the Fresh Linen formulation by Aropha Inc. in 2024.
  • The Fresh Linen fragrance is supplied to IFRA standards — www.ifrafragrance.org. Fragrance Free contains none.
  • Concentrated sheet, not a liquid. There is no water being trucked around: a pack that covers up to 60 washes fits in a letterbox.
  • No plastic jug. The carton is paper-based and recyclable in ordinary kerbside collection.
  • Works cold. The sheets dissolve fully in cold water, which matters because heating water is where most of the energy in a wash cycle goes.
  • Made in Canada, which keeps the freight distance to our two markets short.

What we do not claim

There is a standard vocabulary in this category — a set of phrases that appear on almost every eco-labelled cleaning product. We leave most of them off, because a claim is only worth making if it is specific enough to be checked.

So: no sweeping statements about what is not in the box, and no unqualified environmental adjectives. Where we do make a claim, it is one a certification body has reviewed or one supported by documentation we hold on file.
