"Biodegradable" and "Eco": What the Labels Actually Mean
What biodegradable, OECD-tested and septic-safe actually mean on cleaning labels — and how to spot greenwashing.
Founder & Editor, Mother's Toolkit
The short version
- 'Eco' is not a regulated word
- A named test standard (OECD) makes 'biodegradable' meaningful
- No ingredient list is a red flag
'Eco' isn't a regulated word. Here's how to tell a meaningful environmental claim from a nice-sounding one.
'Biodegradable' — by what standard?
Almost anything biodegrades eventually. The useful question is: under what conditions, and how fast? That's why recognised test standards matter. The OECD has biodegradability tests that give the word real meaning. A brand that names a standard tells you more than one printing a green leaf.
'Septic-safe'
If you're on a septic tank this is practical, not just environmental: it means the formula shouldn't disrupt the bacterial balance your tank relies on.
'pH balanced'
A pH near neutral (around 6–7) is gentler on fabric and skin than a strongly alkaline formula — worth looking for on frequently-washed items.
Spotting greenwashing
- Vague words, no proof: 'natural', 'green', nothing behind them
- One green feature, loud packaging: a plant on a plastic jug
- No ingredient list: if they won't show you, ask why
Victoria's tip
Genuinely eco-minded products do the boring things: publish ingredients, name a standard, use honest packaging.
