Methods of cleansing dyed hair
View Patent ↗Provided are methods of cleansing dyed hair comprising applying to dyed hair a composition comprising anionic surfactant and a hydrophobically-modified polymer capable of binding surfactant thereto.
1. A method of cleansing dyed hair with improved color retention comprising applying to dyed hair a composition comprising at least one anionic surfactant selected from the group consisting of sodium trideceth sulfate, sodium laureth sulfate, and combinations thereof and at least one hydrophobically-modified polymer having a molecular weight of from about 3,500 to about 100,000 selected from the group consisting of hydrophobically-modified starch polymers, hydrophobically modified inulin polymers, and combinations of two or more thereof.
2. The method of claim 1 wherein said composition has a Delta CMC of at least about +80.
3. The method of claim 1 wherein said hydrophobically-modified polymer is a hydrophobically modified starch polymer.
4. The method of claim 1 wherein said hydrophobically-modified polymer is a hydrophobically-modified inulin polysaccharide.
5. The method of claim 1 wherein said composition further comprises at least one amphoteric surfactant.
6. The method of claim 5 wherein said at least one amphoteric surfactant comprises a betaine.
7. The method of claim 1 further comprising the step of rinsing the applied composition from the dyed hair.
