dye transfer inhibitor

2. Chromabond™ S-350 dye transfer inhibitor
Overview
Keeping white garments white and colors their original shade can
be accomplished with dye transfer inhibitor technology.
Chromabond S-350 polymer is a novel dye transfer Inhibitor (DTI) technology
that works by binding to dyes removed from clothing during the wash cycle.
Virtually eliminating the ability of “free dyes” to redeposit on fabric, the polymer
forms stable complexes with various colors, including direct orange, direct red,
direct black and acid blue.
Using Chromabond S-350 polymer at low use levels affords manufacturers the
ability to include consumer-desirable “color-safe” label claims.

3. Chromabond™ S-350 dye transfer inhibitor
Overview
A polymer additive approach offers manufacturers a simple yet
efficient option for adding color-safe label claims.
Chromabond S-350 polymer is based on class-leading Poly Vinyl pyridine N- Oxide (PVNO)
Is stable in bleach containing detergents
Maintains efficacy in the presence of surfactants
May be used in a broad pH range
Performs well at very low concentrations
Is non-hazardous

5. Chromabond™ S-350 dye transfer inhibitor
Function
When included in laundry detergent formulations at 0.3 to 0.6%, manufacturers
generally have the ability to make color-safe label claims, even in regions with
hard water conditions and in elevated wash temperatures.

6. Chromabond™ S-350 dye transfer inhibitor
Function
Included at very low use levels, between 0.1% and 0.2%, Chromabond S-350 polymer out performs legacy dye transfer inhibitor technology, such as PVP polymer. Historically, PVP polymer provided some dye transfer inhibition technology but using a more efficient polymer technology based on Poly vinyl pyridine N-oxide (PVNO) offers better color protection benefits. The difference in performance is measurable and result in formulations that better maintain garment color intensity.

Efficacy testing
Procedures (USA wash conditions):
ASTM D , a dyed cloth is used and the re-deposition of the bled dye from the dyed cloth onto a white cloth is measured.
At Ashland, a known concentration of the dye is added and its deposition onto a white fabric is determined.
Solution containing 10 ppm dye, 10 or 20 ppm polymer, 1g/L detergent and 110 ppm hard water (Ca:Mg 3:1) diluted to 1L with DiH2O and placed in Terg-O-Tometer:
4 dyes chosen as per AISE’s StiWa protocol
Once the solution has equilibrated to 100°F/38°C, two cotton swatches are added and the washing process is conducted for 10 minutes at an agitation rate of 100 cycles/min.
Swatches are removed and rinse water prepared with 110 ppm hard water (Ca: Mg 3:1), which is again diluted to 1.0L with DiH2O and placed in a Terg-O-Tometer. Fabrics are rinsed for 3 minutes and excess water is squeezed by hand.
Swatches are dried.
Six reflectance measurements (3 measurements on each swatch) are taken using a Hunter Colorimeter (ColorQuest XE) on a CIELAB color scale.
The ΔE* value is reported, it is the difference between the starting fabric and the washed fabric. ΔE* value closer to zero indicates less deposition of the dye on to the fabric.
