Benzoyl Peroxide Fastness in Home Textile

The various categories of Home Textile items include towels, bed linens, curtains, blankets, upholstery, kitchen linen, rugs, carpets etc. and play an important role in the comfort, protection and decoration of household. One of the major issues encountered in home textile is a problem of decolorization (in form of spots and patches) of dyed towels, apparels, bed sheets and pillow covers, while using Benzoyl peroxide based cream, gel or lotion for treatment of acne.

Selection of suitable class of dyestuff and combination of dyestuffs in recipe plays a major role to avoid, minimize such de-colorization problem.

Benzoyl Peroxide

It is one of the most important organic peroxides and widely used in personal care and cosmetics for treatment of acne, bleaching of hair and teeth. It consists of two benzoyl groups bridged by a peroxide link (2).

The most common challenge faced by dyers is the problem of decolorization of clothes, towels, bedding, etc. by powerful bleaching effect of benzoyl peroxide while applying or wiping out the cream, lotion, gel after application.

In addition to spillage of the medication, it is easy to unknowingly transfer the chemical onto the fibers from the hands or face. The medication is not readily washed off, leaving behind to get on to the textiles, which causes color loss. The contaminated cloth, towel is not

generally washed immediately and lead time between contamination and washing varies in the range of 24 hours to 7 days. Several classes of dyestuff on cotton are heavily damaged when in contact with benzoyl peroxide. Due to chemical damage of dyestuff, the bleached areas are permanently discolored. The color loss can occur after the contamination of chemical with the dyed fiber sooner or later. The reaction is accelerated by humidity, heat and moisture. It is particularly common for these spills to appear after rainy weather,

or soon after washing of textiles (3).

Dyestuff for Cellulosic Coloration

The coloration of textiles is an important aspect of the production process and adds value to it. The consumption share of different types of dyestuff for cellulosic coloration is shown below:

Due to good fastness properties, reactive dyes are widely used in home textiles segment and other areas, where stringent fastness properties are demanded.

Benzoyl Peroxide Fastness Test

Benzoyl peroxide fastness properties of the dyed swatches are tested using commercially available benzoyl peroxide (including 10%) cream following below mentioned test method:

1-Cut two 4"x4" specimens from the dyed sample.

2-Mark the area on test specimens (2"±0.25" diameter), on which benzoyl peroxide Cream has to be applied for test results.

3-Weigh 0.50±0.05 g of cream on non-absorbing weighing paper.

4-Spread the cream evenly over the entire specimen and work it into the structure of the dyed fabric.

5-Allow the specimen to react with benzoyl peroxide for eight (8) hours±5 minutes at room temperature.

6-Rinse each test specimen thoroughly in distilled water at 40±3°C occasional hand squeezing. To remove excess water, pass the test specimens through wringer rolls.

7-Dry in a nylon mesh bag, exposing at temperature of 60-71°C.

8-Condition the samples for 4 hours before evaluation in standard atmosphere(65%±2% RH)

9-Evaluate color change on the marked area on both specimens using grey scale in light box under D65 light source (4).

Pass - If the change in lightness as assessed using the grey scale is greater than or equal to 4.0 and if there is no perceptible change in hue.

Fail - If the change in lightness as assessed using the grey scale is less than 4.0 and/ or there is a perceptible change in hue.

Given below are the test findings of the effect of benzoyl peroxide fastness studies. Denactive dyes were dyed at various depths from 10 to 40 g/l (80 g/l for blacks) on bleached 100% cotton supreme fabric following exhaust dyeing method. Then, Benzoyl peroxide fastness properties of the dyed swatches were tested using commercially available benzoyl peroxide cream mentioned test method.

Evaluation Results:

It is recommended that the dyed swatches should be tested for benzoyl peroxide fastness (following desired method at laboratory level), before embarking on bulk production.
