Propylgallate (E310) is used as an oxydant for fats and oils.
Propyl gallate is a oil-soluble antioxidant that can prevent or delay the food oxidation. It is also a food additive to improve the stability and extend the storage period. As a result, propyl gallate can be used for oil, fried foods, dried fish products, quick cooking noodles and can and so on. And the maximum usage is 0.1g/kg. Studies show that the excessive taking of propyl gallate is easy to cause cancer.
Different types of urine preservatives are boric acid, tartaric acid, thymol, clorhexidine/ n-propyl gallate and sulphuric acid.
propanol + toluic acid = propyl toluate propanol + toluic acid = propyl toluate
Propyl Toluate is a Benzene ring with a methy(CH3) group bonded to one carbon, and a propyl (CH3CH2CH3) bound to another carbon. Its IUPAC name would #-Methyl-#-propylbenzene
shouldn't it be in alphabetical order when naming alkanes?
The formula for propyl amine is C3H9N. It consists of a propyl group (three carbon atoms in a row) attached to an amino group (-NH2).
The maximum accepted concentration of propyl gallate in foods and cosmetics is approx. 0,1 %.
Propyl gallate is used to protect oils and fats in products from oxidation. It is used in foods, cosmetics, hair products, adhesives, and lubricants.
Paul Alan Brew has written: 'Are the thyroidal effects following exposure to propyl gallate due to a direct or indirect mechanism?'
Different types of urine preservatives are boric acid, tartaric acid, thymol, clorhexidine/ n-propyl gallate and sulphuric acid.
That is propyl alcohol. It will react with ethanoic acid (acetic acid) to make propyl ethanoate (propyl acetate).
propanol + toluic acid = propyl toluate propanol + toluic acid = propyl toluate
Iso-propyl alcohol shows slightly acidic behaviour.
