De­ter­gency

De­ter­gency is the abil­ity to clean or re­move soil, gen­er­ally as­so­ci­ated with the ac­tion of a clean­ing agent such as soap, de­ter­gent, or al­ka­line salt. As per In­dian Stan­dard, the de­ter­gency per­cent­age spec­i­fied for de­ter­gent pow­ders is: 65 per cent min­i­mum for Grade 1, 55 per cent for Grade 2, and 45 per cent for Grade 3. None of the brands met the spec­i­fied re­quire­ment for

Grade 1. The de­ter­gency per­cent­age ranged from 57.68%

(Ariel Matic) to a low of 39.15% (Uni Wash).

Ac­tive in­gre­di­ents

De­ter­gents have cer­tain in­gre­di­ents (known as ‘ac­tive in­gre­di­ents’) that are re­spon­si­ble for en­sur­ing their clean­ing per­for­mance. The na­tional stan­dards have spec­i­fied dif­fer­ent min­i­mum ac­tive in­gre­di­ent lev­els for the three grades of de­ter­gents: 19 per cent for Grade 1, 16 per cent for Grade 2, and 10 per cent for Grade 3. None of the brands claimed the rel­e­vant grade as

spec­i­fied in In­dian Stan­dard. The brands that met the min­i­mum re­quire­ment for Grade 1 ac­tive in­gre­di­ents were: Henko Stain Cham­pion (27.5 per cent), Surf Ex­cel Matic (23.7 per cent), Surf Ex­cel Quick Wash (23 per cent) and Rin (23.2 per cent), Uni Wash (22.3 per cent) and Henko Matic (20 per cent). Ariel Matic (17.9 per cent) did not meet the min­i­mum re­quire­ment for Grade 1 (19%). Tide Plus (14.2 per cent), if ex­am­ined as per Grade 2 (16 per cent), did not match up to the level spec­i­fied for ac­tive in­gre­di­ents. In the low­est price cat­e­gory, Nirma was found to have the low­est lev­els of ac­tive in­gre­di­ents at 7.8 per cent.

Ash built-up

This test de­ter­mines the built-up of ash on a fab­ric. The In­dian Stan­dard has set the re­quire­ment as: 1 per cent max­i­mum for Grade 1, 5 per cent for Grade 2, and 10 per cent for Grade 3.
