AI Technical Summary
Existing technologies suffer from color loss during the washing process of dyed materials (especially hair), particularly due to color weakening and shift caused by the diffusion of dye molecules when in contact with water or solvents. Traditional methods, such as the use of formaldehyde, pose safety risks and are not very effective.
A composition containing hydroxyl-substituted aldehydes is used to contact dyeing materials to reduce or prevent color loss. This method is suitable for dyed or soon-to-be-dyed hair, including human and animal hair.
It effectively reduces or prevents color loss of dyeing materials during washing, especially for hair dyed with oxidative dyes, providing a long-lasting color retention effect.
