Laundry care compositions, methods, and test kits for determining authenticity

A method of determining an authentic laundry care composition, the method comprising the steps of:

• a) providing a laundry care composition having a first color, wherein the laundry care composition comprises at least one laundry care ingredient and at least one leuco composition that conforms to Formula (I):
• Ar1Ar2Ar3CH (I)
• wherein Ar2 and Ar3 are independently carbocyclic aryl or heteroaryl, and Ar1 is selected from the group consisting of:
• unsubstituted phenyl, electron deficient carbocyclic aryl, and heteroaryl;
• b) adding a triggering agent to the laundry care composition, wherein the triggering agent causes the at least one leuco composition to change from a colorless state to a colored state;
• and
• c) detecting the change, wherein the change from the first color to the second color is visually perceptible.

A test kit for detecting authentic laundry care compositions comprising:

• a. a receptacle for receiving an amount of a laundry care product;
• b. a triggering agent, wherein the triggering agent converts a leuco composition conforming to Formula (I):
• c. Ar1Ar2Ar3CH (I)
• i. in a laundry care product from a colorless to a colored state, wherein Ar2 and Ar3 are independently carbocyclic aryl or heteroaryl, and Ar1 is selected from the group consisting of:
• unsubstituted phenyl, electron deficient carbocyclic aryl, and heteroaryl;
• and
• d. instructions for combining the laundry care product and triggering agent to detect authentic laundry care compositions.
