A laundry care composition including (a) at least one laundry care ingredient and (b) a leuco composition. The leuco composition has a first color state and a second color state and the mole ratio of second color state to first color state is from 2:98 to 5:95. Also disclosed are methods of determining the approximate functional age of a laundry care composition comprising the steps of (a) providing a laundry care composition that includes at least one laundry care ingredient and a leuco composition, (b) providing a functional age scale that includes a plurality of distinct colors that correspond to a unique functional age and (c) comparing the color of the laundry care composition with the functional age scale.

A method for monitoring cleaning of a surface includes applying an amount of transparent indicator material to an area of a surface and measuring the amount of transparent indicator material remaining on the surface. The transparent indicator material may be fixed on the surface by drying and, when a fluorescent material, may be measured through exposure to ultraviolet radiation.

A laundry care composition including: (a) at least one laundry care ingredient and (b) a least one compound represented by Formula (I):

##STR00001##

The ratio of Formula I to its oxidized form is at least 1:3 and each individual R.sub.o, R.sub.m and R.sub.p group on each of rings A, B and C is independently selected from the group consisting of hydrogen, deuterium and R.sup.5. At least one of the R.sub.o and R.sub.m groups on at least one of the three rings A, B or C is hydrogen and each R.sub.p is independently selected from hydrogen, —OR.sup.1 and —NR.sup.1R.sup.2, G is independently selected from the group consisting of hydrogen, deuterium, and mixtures thereof. Methods of treating textiles with such detergent compositions.
