Dipropylene Glycol as an odour masking agent
Hi all!
I’ve read from a few sources that dipropylene glycol can be used as an odour masking agent and is particularly good for fragrance free formulations. Does anyone have any experience using DPG for this purpose? What is the minimum amount you would need to ‘mask’ chemical odours for fragrance-free formulations? I use PE 9010 (Phenoxyethanol and Ethylglycerine) at 1% in combination with Sodium benzoate in most of my formulations. The smell of the PE 9010 comes through quite strong, and I am not fond of it. I would like to maintain it as a preservative, but I need to find a way to mask the odour without fragrance. I would appreciate any help.
Thank you!

DPG is used as a neutral solvent for aromachemicals, and is a common filler in fragrance formulation. Used in larger proportion it can change how a fragrance is percieved by altering the rate of evaporation in alcohol-based perfumes. As far as I know, it doesn’t mask smells. -
You can try deoplex from carrubba for odor masking

Thank you for sharing this. What would you define as a “larger proportion”?
