and good luck to you!

Fighting!

Hi

guys, do you know this product Sodium Lauryl Ether Sulfate ?

what's the main role of this substance?

TELL ME!

THANKS!

I think NO.

In the EU, the food additives have an "E-number". Although you should always doublecheck wikipedia if this is for work/school, this list in the link gives a nice impression of all the regulated food additives.

 

In the EU, the complete list of ingredients is always printed on the label (it is mandatory), including all the E-numbers that were used. Here are two examples of labeling in the EU:

 

 

[edit] For those interested, the official E-numbers can also be found online (.pdf warning) but they are giant pdf files.

More guidance than you are ever likely to need.

Yes, this link you give is very very detailed.

Thanks for your information.

I want to know if a 0.02%TWEEN80 solution in PBS buffer will still be homogeneous if I will dilute it with 50% acetonitrile

thanks

I am so confused on a organic nomenclature question. I thought I was getting the hang of it but clearly not...

if anyone can shed some guidance I would be much appreciated.

Hi,Recommend a few books to you

Food additives are to improve the quality of food color, aroma, and taste and so on, and put into food for the needs of the preservation and processing of the compounds or natural substances.

Definition of food additives is not the same in countries around the world, the United Nations food and agriculture organization (FAO) and the world

health organization (WHO) joint committee on food additives food regulations are defined as food additive is consciously general with a small

amount added to the food, to improve the appearance and flavor of food and organizational structure or the nature of the storage of nutrients.

Of course it would.

Many devices are human-made.

What kind of glue you mean ?

Some color of the glue does not affect the use effect.

The uv glue can stick broken glass.

Yes. But I'm not simply going to give you the answer, nor will anyone else. Where exactly are you struggling in trying to answer this?

I just want to know the uses between STPP and SHMP,

What is the difference between their chemical properties?

And other aspects.

Hi,

guys,

do you know which forums are related to food or food additive?

It's called biodiesel or diester, under which names you find much information.

 

"Natural fatty acid" is slightly broader and would include animal fats as the acid source.

 

The most common must be methyl palmitate, obtained from palm oil.

 

The simple transformation keeps three acids and replace a glycerine by three methanols - one viscous oil becomes three molecules of lighter ester.

Oh, yes.

No wonder I can't find more information.

Thanks for your reply!

Is this a homework question?

Yes, I just can't figure this out.

Do you know?

Maybe "C" means Carbon and "I "means Iodine.

I think these are their chemical symbols

More dangerous radioactive material, don't buy if not research as well.

I think the one reason is that many trees on the earth are disappeared, where a lot of old trees are now covered house.

A lot of units in chemistry may be Particles atoms molecules and nano.

These are all the chemical units.

What type of units do you want to know?

Hi,

everyone

Do you know the difference between stpp (Sodium-Tri-Polyphosphate) and shmp (Sodium hexametaphosphate)

and what are the similarities between them?
