A method of combating colour loss from a dyed material, the method comprising contacting the material with a composition comprising a hydroxy-substituted aldehyde.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of combatting colour loss from a dyed material, the method comprising contacting the material with a composition comprising a hydroxy-substituted aldehyde selected from the group consisting of 2-hydroxydecanal, 2-hydroxydodecanal, 2-hydroxytetradecanal, 2-hydroxyhexanal, 2-hydroxypropanal, 2-hydroxyoctanal, 3-hydroxypropanal, 4-hydroxy-but-2-enal, 2-hydroxybutanal, 3-hydroxybutanal and 4-hydroxybutanal. 2. The method according to claim 1 wherein the material is a keratinous material. 3. The method according to claim 2 wherein the material is human hair or animal hair. 4. The method according to claim 3 wherein the material is growing human hair or animal hair. 5. The method according to claim 1 wherein the composition comprising the hydroxy substituted aldehyde is selected from the group consisting of: a shampoo composition, a conditioning composition, a hair styling composition, a hair permanent waving composition, a hair relaxing composition, a hair permanent straightening composition and a hair coloring composition. 6. The method according to claim 1 wherein the composition comprising the hydroxy substituted aldehyde further comprises 1 to 30 wt % of one or more surfactants. 7. The method according to claim 1 wherein the aldehyde is an alpha-hydroxy aldehyde. 8. The method according to claim 1 wherein the aldehyde is selected from the group consisting of 2-hydroxypropanal, 2-hydroxyhexanal, 2-hydroxyoctanal, 2-hydroxydecanal, and 2-hydroxybutanal. 9. The method according to claim 8 wherein the aldehyde is selected from the group consisting of 2-hydroxypropanal, 2-hydrohexanal, and 2-hydroxyoctanal. 10. The method according to claim 1 comprising a first hydroxy-substituted aldehyde having less than 10 carbon atoms and a second hydroxy-substituted aldehyde having 10 or more carbon atoms. 11. The method according to claim 10 wherein the second hydroxy-substituted aldehyde is selected from the group consisting of 2-hydroxydecanal, 2-hydroxydodecanal and 2-hydroxytetradecanal. 12. The method according to claim 10 wherein the first hydroxy-substituted aldehyde is selected from the group consisting of: 2-hydroxypropanal, 2-hydroxyhexanal and 2-hydroxyoctanal and the second hydroxy-substituted aldehyde is selected from the group consisting of; 2-hydroxydecanal, 2-hydroxydodecanal and 2-hydroxytetradecanal. 13. The method according to claim 1 wherein the composition comprising the aldehyde further comprises an amine of a salt carboxylic acid. 14. The method according to claim 1 wherein the composition comprising the aldehyde further comprises a polycarboxylic acid derived chelating agent. 15. The method according to claim 1 wherein the composition comprising the aldehyde further comprises a succinimidyl ester. 16. The method according to claim 1 wherein the composition comprising the aldehyde further comprises a crosslinking agent comprising two or more maleic acid derived reactive moieties and a linker having two or more amino groups. 17. The method according to claim 1 which reduces colour loss by at least 20% compared with a material dyed by an equivalent method excluding the hydroxy substituted aldehyde. 18. The method according to claim 1 wherein the dyed material is a textile material. 19. The method according to claim 18 which combats colour loss resulting from washing a dyed textile material in a laundry washing process.
