NATRLQUEST E30

CAS No.: 178949-82-1
EINECS No.: 416-530-4

IUPAC Name: trisodium;(2S)-2-[2-[[(1S)-2-carboxy-1-carboxylatoethyl]amino]ethylamino]butanedioate

Trisodium Ethylenediamine Disuccinate

Natrlquest E30 is a biodegradable chelating agent that is special in the fact that it is very selective towards problematic transition metals such as Cu and Fe compared to Ca and Mg. This makes it ideal in personal care formulations as it is tackling these problematic transition metals first while in the formulation, but still giving hard water control when released into water.
This gives Natrlquest the benefit of excellent anti-oxidant properties and foam preservation in shampoos and conditioners.

Metal Chelation
Natrlquest E30 can complex a range of metal ions over a broad pH.
The maximum chelation occurs approximately in the centre of the pH range at around pH7 – that of water.
Natrlquest E30 is special in the fact that it is very selective towards problematic transition metals such as Cu and Fe compared to Ca and Mg.
This makes Natrlquest E30 ideal in personal care formulations as it is tackling these problematic transition metals first while in the formulation, but still giving hard water control when released into water.
This gives Natrlquest the benefit of excellent anti-oxidant properties and foam preservation in shampoos and conditioners.

Peroxide Stabilisation
Natrlquest E30 is used commercially in peroxide based products.
Natrlquest E30 is much better, for instance, in stabilising peroxide against decomposition by iron compared with alternative biodegradable chelants.

Biocide Potentiation
Natrlquest E30 is used to enhance the activity of preservatives in personal care formulations, improving efficacy and allowing the level to be reduced.
Natrlquest E30 is not a preservative by itself.
Minimum inhibitory concentration (MIC) measurements demonstrate the effect:

Anti-Oxidant
Metal ions can react with oxygen in the air to form radicals and other reactive species that can lead to discolouration and odours.
Even in trace amounts metal ions can cause side reactions and so it is vital for the formulator to bind these up with a chelating agent.
Metal ions such as Fe and Cu can be introduced into formulations through raw materials, particularly water, from the air or from plant equipment.

Peroxide Stabilisation
In peroxide formulations, metal ions react with the peroxide causing the peroxide to decompose and for radicals to be generated.
Chelants work by binding to metal ions in formulations and so prevent these ions causing these side reactions.
This gives formulations greater stability and longer shelf life.

Biocide Potentiation
Biocides and preservatives are potent additives that are designed to kill unwanted bacteria in formulations.
Bacteria can be introduced at low levels during manufacture of formulations or at higher levels when opened or touched by the consumer.
Chelating agents have been found to enhance the activity of biocides and so allows significantly lower levels of biocides to be used.
This is good for the consumer as it reduces the levels of active chemicals that can cause irritation or sensitization and also reduces the amount of biocide released into waste water.
This is also good for the manufacturer as it reduces their cost.

Reducing Water Hardness
Water hardness ions such as Ca and Mg reduce the effectiveness of surfactants in cleasing producs leading to poor foam quality and poor cleaning.
Chelants bind up these ions from tap water and help enhance the performance of surfactants
