Gold Reef Chemicals
Goes Green
One of the fundamental key values of GOLD REEF SPECIALITY CHEMICALS
is the sustainability of the environment. We have proactively implemented
numerous initiatives to minimize our environmental impact. We are committed to sustainable
environmental management to ensure a better world for future generations.
It is this concern for the environment that has motivated us to research and develop a range of
emulsions that are environmentally friendly. Our new range of products includes products that
are APEO-free. These APEO-free products have been certified to international standards by an
international laboratory based in Hong Kong.
So what is APEO-free and why all the fuss?
Alkyl Phenol EthOxylates (APEO) are Nonyl Phenol compounds (NPEO). APEO are non-ionic
surfactants with an emulsifying and dispersing action, which makes them suitable for a very
large variety of applications. Alkyl Phenol EthOxylates and especially Nonyl Phenol EthOxylates
are considered to be very toxic for aquatic life. In Europe, America and in most first
world countries these emulsifiers/surfactants are no longer allowed/wanted.
Concerns currently focus on Alkyl Phenol EthOxylates (APEO) and in particular on Nonyl Phenol
EthOxylates (NPEO), which are often contained in the formulations of detergents and many other
auxiliaries (e.g. dispersing agents, emulsifiers, spinning lubricants).
Alkylphenol ethoxylates are themselves believed to be endocrine disruptors and to cause
feminization of male fish. More importantly, however, they produce metabolites
which are believed to be many times more potent as endocrine disruptors
than the parent compounds.

Show your commitment
to caring for the
environment and switch
to our environmentally
friendly products.
