Overview

A sodium percarbonate booster with three enzymes (amylase, lipase, subtilisin). In water it releases active oxygen that lifts yellowing, greyness and sweat marks on collars and cuffs — without chlorine bleach. It's a booster, not a detergent, so it's meant to be used alongside the laundry sheets.

Pros

  • Bleach-free and chlorine-free whitening
  • ECOCERT certified with full INCI + CAS disclosure
  • Works in the machine or as a 1–4 hour soak
  • Refill pouches mean you keep the same jar

Cons

  • Must be used with a detergent
  • Small review base (65 ratings)
  • Less effective on cold cycles — best from 30°C

A closer look

How it works

Sodium percarbonate breaks down into hydrogen peroxide and soda ash in water, releasing active oxygen that oxidises stains. The three enzymes each target a different stain family: starch, grease and protein (sweat, blood). It's the same chemistry as the 'oxygen bleach' powders sold in supermarkets, minus the plastic tub.

Results

Buyers mostly use it for greying towels, white shirts and bedding. Reviews are positive but the sample is small (65 ratings), so treat the average with a little caution.

Certification and packaging

It's ECOCERT-certified as an 'Ecodetergent', the full ingredient list is published with CAS numbers, and refills come in a recyclable cardboard pouch so you keep the original jar.

Price and value

Who should buy it?

Households with white shirts, towels and bedding that have gone grey or yellow, and anyone replacing chlorine bleach.

Our verdict — 8.7/10. Bleach-free and chlorine-free whitening. Main trade-off: must be used with a detergent.
