Novel colorimetric sensor for oral malodour.
Anal Chim Acta
February 2010
Hindustan Unilever Research Center, 64 Main Road, Whitefield, Bangalore 560066, India.
Article Synopsis
- Volatile sulphur compounds are the main cause of bad breath, and a new tool has been developed to detect and measure its intensity.
- The colorimetric sensor works by reacting iodine with hydrogen sulfide present in mouth air, allowing for a precise evaluation of oral malodour.
- The sensor has a low detection limit and shows strong correlation with existing methods, making it a promising clinical tool for assessing bad breath in patients.
An agglomeration-based model for colloid filtration.
Environ Sci Technol

Hindustan Unilever Research Center, 64 Main Road, Whitefield, Bangalore, India 560066.
This paper develops a model for colloid filtration which accounts for the possibility of aggregation of the colloidal particles in the aqueous phase. Depth-wise variation of liquid-phase colloid concentration, C(x), is measured experimentally in the presence of monovalent cations at different concentrations and divalent cations, which confirm that log of C(x) deviates significantly from linearity for all of the above cases. It is also observed that in all systems showing significant removal, preaggregation of the colloids is observed, which confirms the correlation between aggregation of colloids with their retention in saturated porous media, which has been reported earlier.
