Is your Laundry Detergent Bar the Best?

The following comparative assessment of laundry detergent bars gains significance in light of the fact that the Bureau of Indian Standards (BIS) has revised certain important parameters including detergency. Other parameters that have been revised are ash built-up and phosphate limit. All of these ultimately determine the overall quality of the product you are using. While foaminess and mushiness are perhaps the qualities that we notice more while using a detergent bar, there are other aspects that are equally or more crucial. Due to the large number of detergent bars available in the market, the process of selecting a ‘best’ brand is often a formidable one. In order to find out if some of the better-known detergent bars are complying with the national standards and how these come out on quality parameters, we tested nine brands.

Brands Compared: Reliance Sudz, Henko, Surf Excel, Rin, Fena, 555, Gharu, Clean Mate and Patanjali

Apart from detergency, phosphate and ash built-up, the tests covered other parameters related to quality and acceptability. These included foam generation, mushiness, insoluble matter, active ingredients and active alkalinity.
The Indian Standard defines four grades of detergent bars but none of the nine brands have declared their grades since it is voluntary.
The samples were tested as per requirements specified in the relevant Indian Standard 8180, specifications for household laundry detergent bar and its finalized revised draft that is under printing. The tests were conducted at an NABL-accredited laboratory.
