Dye transfer inhibitors

Dye transfer inhibitors (LD) Prevent dye transfer and preserve color of garments during washing Complexing power Polyvinylpyrrolid one polymers 0.05-0.5%... 

Choose specific perfumes to mask malodors by identifying their source, such as ethoxylated alcohol nonionic surfactants (fatty malodors) and PVP dye transfer inhibitors (mouse-like odor). 

Fatty alcohol (co-softener), fatty acid ester (co-softener), fatty amides (co-softener), amido amines (co-softener), polyethylene terephthalate (soil release agent), PVP-type polymers, (dye transfer inhibitor)... 

Dye transfer is the result of dye removal. In a mixed load, dye removed from garments is free in solution and then deposits on another garment, changing its color. An example is the addition of a red sock to a load of whites, resulting in pink garments. Dye transfer is particularly obvious on pastels and light colors, but can occur in all wash types. This can be counteracted by a class of polymers known as dye transfer inhibitors (DTI). Dye transfer inhibitors, such as polyvinylpyrrolidone and its derivatives, reportedly interact with dye molecules in the wash liquor and act as antiredeposition agents [37-39]. The effectiveness of DTIs is dye dependent and formula dependent. 

Multiaction powders with <50% persalt, but with special ingredients, such as optical brighteners, photobleaches, enzymes, or dye transfer inhibitors... 

Trace levels of unreacted alcohol cause problems in traditional nonionics while all ethoxylated amines have a minimum of two EOs prior to building the chain. Again, an advantage in theory. By also acting as dye transfer inhibitors, amine ethoxylates have a definite advantage over AE. The weak point of ethoxy-... 

Laundry detergent, fine-fabric wash, and laundry prespotter formulations can also use amine oxides because of their good soil removal, particularly the greasy soil removal properties, and also because amine oxides act as dye transfer inhibitors for certain dyes.
