Methods for Shaping Fibrous Material and Treatment Compositions Therefor

A treatment composition for shaping fibrous material comprising:

• (a) an active agent, wherein the active agent comprises a high-polarity functional group selected from the group consisting of hydroxyl groups, carboxylic acid groups, and combinations thereof;
• wherein the active agent further comprises one or more of the following:
• (i) at least one carbon atom which is not functionalized with a hydroxyl and/or carboxylic acid group;
• (ii) fewer than three total high-polarity functional groups selected from the group consisting of hydroxyl groups and carboxylic acid groups;
• and/or
• (iii) no single carbon atom that has both a hydroxyl group and a carboxylic acid group;
• and
• (b) a photocatalyst.

A kit comprising:

• (a) a treatment composition comprising:
• (i) an active agent comprising a high-polarity functional group selected from the group consisting of hydroxyl groups, carboxylic acid groups, and combinations thereof;
• and
• (ii) a photocatalyst;
• and
• (b) an appliance for mechanically shaping fibrous material, for providing electromagnetic radiation, and/or for providing heat.
