propyl paraben being a stable compound with reproducible chromatographic parameters used as a internal standard for the calibration of the HPLC systems
That is propyl alcohol. It will react with ethanoic acid (acetic acid) to make propyl ethanoate (propyl acetate).
Propyl-Paraben is in the paraben family of preservatives. It is found in nature and is also man-made, but used in cosmetics, and foods for preservation.Ê
Propyl gallate is used to protect oils and fats in products from oxidation. It is used in foods, cosmetics, hair products, adhesives, and lubricants.
propanol + toluic acid = propyl toluate propanol + toluic acid = propyl toluate
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.
Iso-propyl alcohol shows slightly acidic behaviour.
propyl alcohol
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
The maximum accepted concentration of propyl gallate in foods and cosmetics is approx. 0,1 %.
Propyl acetate has one more carbon atom.
