Abstract
Official abstract text for this publication.
A method of treating a 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 treating a keratinous material, the method comprising contacting the keratinous material with a composition comprising an aliphatic aldehyde having a single hydroxyl substitution; wherein the aliphatic aldehyde has at least 3 carbon atoms and the single hydroxyl substitution is at the 2 position. 2. The method according to claim 1 wherein the material is human hair or animal hair. 3. The method according to claim 2 wherein the material is growing human hair or animal hair. 4. The method according to claim 2 which provides one or more benefits selected from the group consisting of increased gloss or shine, improved combability, improved strength, increased softness, reduced protein loss, improved thermal durability, increased chemical resistance, increased waviness and increased straightness. 5. The method according to claim 4 wherein the benefit may be temporary, semi-permanent or permanent. 6. The method of claim 1 wherein said aliphatic aldehyde having a single hydroxyl substitution is selected from the group consisting of 2-hydroxypropanal, 2-hydroxyhexanal, and 2-hydroxyoctanal. 7. The method of claim 1 wherein the composition comprises said aliphatic aldehyde having a single hydroxyl substitution and less than 10 carbon atoms and a second aliphatic aldehyde having a single hydroxyl substitution and 10 or more carbon atoms. 8. The method of claim 7 wherein the second aliphatic aldehyde having a single hydroxyl substitution is selected from the group consisting of 2-hydroxydecanal, 2-hydroxydodecanal and 2-hydroxytetradecanal. 9. The method of claim 7 wherein the first aliphatic aldehyde having a single hydroxyl substitution is selected from the group consisting of 2-hydroxypropanal, 2-hydroxyhexanal or 2-hydroxyoctanal and the second aliphatic aldehyde having a single hydroxyl substitution is selected from the group consisting of 2-hydroxydecanal, 2-hydroxydodecanal and 2-hydroxytetradecanal. 10. The method of claim 1 wherein the composition comprising the aliphatic aldehyde having a single hydroxyl substitution further comprises an amine salt of a carboxylic acid. 11. The method of claim 1 wherein the composition comprising the aliphatic aldehyde having a single hydroxyl substitution further comprises a polycarboxylic acid derived chelating agent. 12. The method of claim 1 wherein the composition comprising the aliphatic aldehyde having a single hydroxyl substitution further comprises a succinimidyl ester. 13. The method of claim 1 wherein the composition comprising the aliphatic aldehyde having a single hydroxyl substitution further comprises a crosslinking agent comprising two or more maleic acid derived reactive moieties and a linker having two or more amino groups. 14. The method according to claim 2 wherein the composition is selected from the group consisting of a shampoo composition, a conditioning composition, a hair dyeing/colouring composition and a hair styling composition selected from the group consisting of a hair permanent waving composition and a hair permanent straightening/relaxing composition. 15. The method according to claim 10 wherein the composition comprising the amine salt of a carboxylic acid further comprises 1 to 30 wt % of one or more surfactants, preferably one or more anionic surfactants.
