Conditioner Composition Comprising a Chelant

A hair conditioner composition comprising:

• (a) from about 0.005% to about 10% of one or more chelants, by weight of the hair conditioner composition, wherein the one or more chelants comprise a Class I chelant and/or a Class II chelant, wherein the Class I chelants are represented by molecular structure I:
• wherein
• M is hydrogen or a metal ion;
• R1, R2, R3, and R4 are independently selected from the group consisting of hydrogen, —COOM, hydroxyl, —NH2, methyl, ethyl, propyl, butyl, pentyl, phenyl, and combinations thereof;
• and wherein the Class I chelant comprises:
• (3) log of the formation constant log KML of its complex with copper is greater than 3;
• (2) log P value is from about 0 to about 5;
• and
• (3) molecular weight is from about 123 to about 350;
• and wherein the Class II chelants are represented by molecular structure II:
• wherein
• M is hydrogen or a metal ion;
• R5, R6, R7, R8, R9, and R10 are independently selected from the group consisting of hydrogen, —COOM, hydroxyl, —NH2, methyl, ethyl, propyl, butyl, pentyl, phenyl, and combinations thereof;
• and wherein the Class II chelant comprises:
• (3) log of the formation constant log KML of its complex with copper is greater than 3;
• (2) log P value is from about 0 to about 5;
• and
• (3) molecular weight is from about 173 to about 400;
• (b) from about 0.1% to about 20% of one or more high melting point fatty compounds, by weight of the hair conditioner composition;
• (c) from about 0.1% to about 10% of a cationic surfactant, by weight of the hair conditioner composition;
• and
• (d) from about 75% to about 98% of an aqueous carrier, by weight of the hair conditioner composition;
• wherein the hair conditioner composition has a pH from about 3 to about 8.
