The maximum accepted concentration of propyl gallate in foods and cosmetics is approx. 0,1 %.
That is propyl alcohol. It will react with ethanoic acid (acetic acid) to make propyl ethanoate (propyl acetate).

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.
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.

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
pr
Propyl acetate has one more carbon atom.
shouldn't it be in alphabetical order when naming alkanes?
