example 1

Clothing contaminated with stains identified in Table 1 was obtained from a commercial supplier (Equest, stains aged for three days, then sealed). The stained garments were then treated with solutions of ethanol-containing various radical photoinitiators and then placed in an Atlas 53000 Weatherometer WOM (Trade Mark) for 12 minutes (at a power of 0.35 W / m ² at 340 nm). The results of the reflectance change at 460 nm (R (460 nm)), measured using a Spectraflash SF60 (Trade Mark) Reflectometer, are shown in Table 4.

• Behandlung 1 – kein Eintauchen.
• Behandlung 2 – man legt die verfleckte Bekleidung in Ethanol, entfernt und trocknet, befeuchtet mit Wasser, legt in Weatherometer für 12 Minuten.
• Behandlung 3 – man legt in Ethanol, enthaltend 0,20 Gewichtsprozent Irgacure 2959 (Handelsmarke), entfernt und trocknet, befeuchtet mit Wasser, legt in WOM für 12 Minuten.
• Behandlung 4 – man legt in Ethanol, enthaltend 0,20 Irgacure 819 (Handelsmarke), entfernt und trocknet, befeuchtet mit Wasser, legt in Weatherometer für 12 Minuten.

The following treatment regimens were used:

• Treatment 1 - no immersion.
• Treatment 2 - Place the stained clothing in ethanol, remove and dry, moisten with water, place in Weatherometer for 12 minutes.
• Treatment 3 - Remove Irgacure 2959 (Trade Mark) in ethanol containing 0.20% by weight and dry, moisten with water, place in WOM for 12 minutes.
• Treatment 4 - Remove in ethanol containing 0.20 Irgacure 819 (Trade Mark), remove and dry, moisten with water, place in Weatherometer for 12 minutes.

The Results are shown in Table 1.

Table 1

in the Generally lead the radical starters increase the reflection at 460 nm for a variety of spots. That is, the radical starters effectively bleach the patches of textile.

Example 2

The The procedure of Example 1 was repeated using treatment 1, 2 and 4, except that the amount of Irgacure 819 (trademark) in which ethanol was varied. The results are in table 2 shown.

Table 2

The Results show that the bleaching of the stains is very low obtained on-weight textile portions of radical photoinitiator can be.

Example 3

The following experiment was performed to compare the effect of different radical initiator systems on stains and on dye. A variety of stained cotton garments were obtained from Equest as above. Photoinitiators at various proportions on weight textile (owf) were applied to the stained garments of ethanol. The ethanol was then evaporated, the clothes moistened with demineralised water and placed in an Atlas 53000 Weatherometer (Trade Mark) for 12 minutes irradiation (power = 0.35 W / m ² at 340 nm). At 460 nm reflectance was measured for the stained garments and for a piece of non-stained fabric, producing ΔE values. The values were compared to a control where the spots were exposed to the same treatment, except that the ethanol did not contain a free radical initiator. It was found, as in Example 1, that the starters were particularly good at bleaching curry, bolognese, β-carotene and chilli. Tables 3 and 4 give an average reduction in ΔE above the control found for these four stains of Irgacure 2959 and 819 (Trade Mark) at various levels by weight of fabric.

Around to judge how bad the starters were damaging the dyes the above experiments are repeated, except for printed Clothing obtained from Veebee The of Harrogate England which was used instead of stained textile. In this case give the ΔE values dye damage again. 16 different dyes were tested and the average Dye damage, which was measured is given in Tables 3 and 4.

The dyes were as follows:

The Stain removal measurement was divided by dye damage measurement gaining value of benefit / damage, which is a measure of how specifically, the starter is to the patches rather than to the dye. It can be seen that Irgacure 819 (trademark), wel ches has a log P above 2.5, is much better spot specific as Irgacure 2959 (trademark), which has a log P below 2.5 having. This is especially true at low levels (0-0.02 owf), when Irgacure 819 (trademark) great blotchy benefits results, but only very small dye damage.

Table 3

Table 4

It It should be noted that when using the experiments of dry clothing were repeated, much less dye damage was observed has been. Blotch bleaching, however, was also diminished.

Examples 4 and 5

The following basic powder was prepared:
linear sodium alkyl benzene sulphonate (LAS) 23,60
Sodium tripolyphosphate - 19,22
Sodium silicate - 4.81%
Sodium sulfate - 28.59
Calcite - 10,30
Low Ingredients - 1.08
Water - 12,49

In Example 4 was 1 gram of this base powder with 0.024 g Irgacure 819 intimately mixed. The final product contained 2.3 percent by weight Irgacure 819. In Example 5, 1 gram of the base powder was 0.024 g Irgacure 369 intimately mixed. The end product thus contains 2.3% by weight Irgacure 369.

In each example was the mixture of base powder and free radical Photostarter dissolved in 400 grams of water at 40 ° C. Three quantities of cotton clothing have been produced. Each contained weights of 16.1 grams in total and brushed Cotton weighing 10 grams in total. The whole Clothing was white. For every Amount, both types of clothing were cut into four pieces. The amounts were then 5 minutes in the solution prepared above washed. One piece Cotton cloth and a piece brushed Cotton was removed and dried. The washing solution was discarded and rinsed the cotton with 600 grams of cold water. One Piece of the Cotton cloth and brushed Cotton was removed and dried. The first rinse solution was then discarded. A second flush was then carried out with another 600 grams of water. In turn became a piece Cotton cloth and a piece brushed Cotton removed.

The pieces of cotton cloth and brushed Cotton removed at each step were tested to see how many starters are on the clothing would have. This was done by measuring the reflectivity of the dried garments at 320 nm, using a Spectraflash SF60 (Trademark) Reflection spectrometer, measured. The following Results were obtained:

Table 5 - Clothing cloth

Table 6 - Brushed cotton

In all cases, the reflectance of the cloth washed with powder compositions containing free radical initiators is lower than that of the control composition which does not contain a free radical initiator. This is because the radical starter strongly absorbs Irgacure at 320 nm while reducing the reflectance. The changes in reflectivity that were measured were significant above the noise for this measurement and confirm the deposition of the starter.

Examples 4 and 5 show that the radical photoinitiator on textile off a laundry composition can be separated.

Example 6

The following rinse conditioner formulation was prepared:
HEQ - 4%
Perfume - 0.3%
Irgacure 819 (trademark) - 0.66
Water - at 100

3 Gram of this rinse conditioner were dissolved in 600 grams of cold water. 18 grams of cotton towels were for 5 minutes put in. At the end of this period, the cotton was removed and dried. The reflection spectrum of the cotton cloth was at 320 nm using a Spectraflash SF60 (trademark) Reflectometer examined.

It was calculated from the reflection results that about 0.003% radical photoinitiator (based on the weight of the cloth) delivered were.

Example 7

Of the The following experiment was carried out to determine the effect of the pH to test for the effects of radical photoinitiators.

The The procedure of Example 6 was repeated except that Irgacure 819 (trademark) made of ethanol on stained clothing at 0.1% on weight textile was applied. For each spot were separated Samples and then with buffer solution of varying pH wetted. The resulting garments were stored for 12 minutes in the Atlas 53000 (Trademark) Weatherometer irradiated. The variation of the average Reflection at 460 nm after treatment is shown in the table. The average reflection at 460 nm for the four treatments was 46.5. It can be seen that the radical photoinitiator show a significant improvement in the reflection over a wide pH range.

Angefleckte, white Polyester clothing (Veebee Tech) was startered as in previous ones Examples treated and good cleaning action against control found. Little damage was stained on Polyester clothing found.

Example 10

Oily tomato stains were produced by smearing a tomato paste (Traditional Ragu Recipe Van den Bergh foods, ingredients: tomatoes, sunflower oil, onion, salt, sugar, dextrose, garlic powder, basil, parsley, spice extract, citric acid, basil, parsley, CaCl ₂ ) on cotton cloth and then aged in air for 1 day. The stained garments were washed in a linitol test under the following conditions: each pot contained 12 g of clothing (of which 6 g were stained), 240 ml of water, 0.34 g of borax, 1.44 g of liquid detergent. 40 degrees C, 20 minutes, and no rinse. Garments were dried in a drum dryer, then placed in a WOM for 6 minutes.

Liquid detergents were made from Coco5E0 (from Clariant - a nonionic surfactant), SDS (sodium dodecylsulfate - a anionic surfactant), CTAC (cetyltrimethylammonium chloride - a cationic Surfactant), Arquad 2HT (from Akzo Nobel - a cationic surfactant), with 0.1% Lucerin TPO-L and 10% ethanol by weight of the formulation, the remainder being water. The amount of surfactant in each Formulation is given in the table:

The Results are shown below; in all cases the samples containing the starter have lower ΔE values (better stain removal) as the control.

Example 11

Formulation L1 of Example 10 was prepared using Irgacure 819 instead of TPO-L posed. Good stain removal advantages over the control were obtained.

Example 12

A Detergent composition was produced, the 15.3 of an anionic Surfactants, 10% ethanol, 0.1% Lucerin TPO-L, balance water. The anionic surfactants were LAS and SDS.

she were tested using the wash protocol of Example 10; both showed a high increase in the stain removal advantage on irradiation, compared to a Control of water only. This indicates that the starter of the Laundry was effective. Benefits are also for β-carotene and a paprika stain found.

Example 13

Liquid Persil was purchased from Ireland and 0.01, by weight, Lucerin TPO-L given to the product. On washed, rinsed and irradiated cloth, stained with β-carotene, became much more Spot removal found if the starter was present.

Example 14

The Starter, benzoin, dimethoxyphenylacetophenone, benzoin methyl ether and benzoin ethyl ether (ex Aldrich) were separated from ethanol on cotton clothing that stains with β-carotene was, applied. Everything bleached the stain. As expected, showed the starters with higher logP value less dye damage.
