Ethy-Gen® II Ripening Concentrate

Ethy-Gen® II:
Powerful. Clean. Pure. Approved.

Ethy-Gen® II’s active ingredient is all-natural & GMO-free, and is the only “ripening fluid” authorised by both the UK Chemicals Regulation Directorate (CRD) and the US EPA.  And now the Dutch Ctgb!


Since we manufacture Ethy-Gen® II with only the purest ingredients available, there are no harmful byproducts produced when converted to ethylene in one of our Catalytic Generators.

Don’t be fooled by copycat “ripening fluids.”  There’s only one that has passed the stringent standards of the UK-CRD, US EPA and Dutch Ctgb….Ethy-Gen® II.  So you can be sure of the purity and safety of what comes out of the ethylene generator when you only pour in Ethy-Gen® II!

  • Ethy-Gen® II is sourced from grain not petroleum, making it more environmentally friendly and from renewable sources.
  • Ethy-Gen® II and the compounds emitted from its conversion through a catalytic generator have been extensively tested by a third party as directed by UK-CRD and are authorised for the use in ripening fruit. Don’t use untested and unapproved ripening fluids; these may result in inferior and unsafe by-products!
  • Ethy-Gen® II is fully labeled and batch numbered for traceability.

Use of illegal ripening fluids
You may have heard of some confusion in the past, particularly in the UK, where some companies were selling unregistered ripening products. In order to distinguish between these illegal products and Catalytic Generator’s legal ones, please click here to read the statement made by the UK’s Chemical Regulation Directorate (CRD) of the Health & Safety Executive (HSE) about this issue: CRD Statement.

The unique sweet smell of Ethy-Gen® II
Also, ethylene is odorless and without measuring the level in the room, there’s no way to know it is present in the ripening room.  No ethylene = no ripening.  That’s why ethylene created from Ethy-Gen® II has a slight sweet smell…letting you know it is there, doing the work to help make delicious fruit.
