When dispensing aqueous compositions from aerosol containers,
In addition to the aqueous composition, the container contains enough aerosol to provide adequate pressure to dispense the solution upon each actuation of the aerosol valve until substantially all of the composition is consumed. Propellants or propellant systems that can be used, which may include propellants or propellant mixtures, are well known in the art. Typical examples of propellants that can be used are low-boiling chloro- and fluoro-substituted alkanes, and low-boiling aliphatic hydrocarbons, such as propane/isobutane mixtures.

The composition has an alkaline pI] range, i.e. about 7.5 to 9.
, 5. This is because acidity and H may have a harmful effect on this type of metal component. However, compositions with pt-+ in the acidic range can be dispensed from aerosol containers that are substantially free of exposed internal metal components, such as those with internal metal walls coated with plastic material.

It is convenient to first add the surfactant to most of the required calculated amount of water, then add the fluorine compound mixture, then the optional ingredients, and then add the remaining water. If a pH adjuster is to be added, add sufficient pH adjuster to achieve the desired pH just before adding the remaining water.

The composition is applied, for example, by spraying, at a rate of about 59/ft" per ft, the composition is then allowed to penetrate into the treated area for about 1-3 minutes, and the area is then exposed to suitable equipment. , for example with a clean damp cloth or sponge mop, rinsing the cloth or mop as necessary.
Cleaned by rubbing until no stains appear on the cloth or mop. The cleaned area is then dried.

Under normal temperature and humidity conditions, the cleaned area should be approx.
It will dry within 5 to 20 minutes; drying times will vary depending on humid climate and whether the pile rug is coarse or dense, etc. There is generally no need to use a vacuum cleaner.If the composition is applied from an aerosol container, cleaning can, if desired, be completed by vacuuming the treated carpet after the carpet is dry, instead of mopping. .

; 6.37) was prepared.

The compositions of Examples 1, 2, and 3 were compared to Compositions A, B, and C, respectively, for their effectiveness in imparting stain resistance to carpet. The method adopted was the walking method (traffi).
This test consists of a test including a cutting procedure), in which an unused beige cut pile carpet) - swatch (approximately 30em x 3 Oc 1"
×1゛〉 was placed in the excised test area of basic carvera 1~ in a place with a lot of foot traffic, and people passed through this area concentratedly. Carvet swatches were treated with each composition as described below before walking, and then treated with a Minolta Tristeimulus Colorimeter Model No. before and after contamination, i.e. after walking.

Instrumentally analyzed for color reflection by CRIIO.

The test swatches were walked along with untreated controls for 71,000 steps. This represents at least one year's worth of walking pollution in a typical household. The number of steps was measured by an electronic counter placed under the carpet in the test area. The treatment method adopted was as follows. That is, each composition was applied to the test carpet swatch at approximately 542 g/ft".
9 compositions were applied using a container with a trigger spray pump set in the "spray" position at a volume of The test carpet was left on for 3 minutes, then mopped 20 times in each direction with a damp standard sponge.The test carpet was then mopped again with a fresh moderately wet sponge, 10 times in each direction.

Next, air dry the test carpet swatch! ,Ta.

Table 1 shows the difference (ΔE) in color reflection of the control (untreated and treated carpet swatches) before and after contamination (walking), respectively.In Table 1, the smaller the ΔE, the better the antifouling effect.1ΔE Differences in units are usually visible to the trained eye.

This shows that the carpets treated with compositions Nos. 2 and 3 had significantly superior stain resistance.

A comparative test was conducted to determine whether the presence of the stain-resistant fluorine compound mixture in the composition impairs the cleanability of the carpet. The walking and washing methods and color reflectance measurement methods employed in this test were as described above. Measuring the color reflectance of an unused, unwashed carpet and then walking on the carpet for 71,000 steps)
The carpet was then cleaned with a carpet cleaning composition. The carpet swatches used had not been previously antifouled by the manufacturer. The results are shown in Table 1. In Table 1, the smaller ΔE is, the closer the appearance to Carbella (2) is to that of an unused carpet.
