This extends the effectiveness time of the เอเจนต์.
Moreover, reactive active ingredients can also be
formulated in the hydrophobic matrix without losing the effect even within a short time.

Depending on the active ingredient added, the เอเจนต์ can be formulated for removing a very wide variety of stains or deposits.
10 In a first variant, the เอเจนต์ ประกอบรวมด้วย, besides
สารลดแรงตึงผิว and the สารส่งเสริมการยึดเกาะ, at least 10% by
weight of acid as active ingredient. Such an เอเจนต์ can
be used for removing acid-soluble stains.
15 Surprisingly, it has been found that such an acidic
stain remover, in particular with อัลคิลีน styrene
โคโพลิเมอร์ dissolved in hydrophobic solvents as
สารส่งเสริมการยึดเกาะ, สารลดแรงตึงผิว and at least 10% by
weight, ที่ควรใช้คือ at least 15% by weight and
20 ที่ควรใช้ เป็นพิเศษคือ at least 20% by weight of acid,
is superior over conventional เอเจนต์ for removing
stains from textiles in the armpit area. The stain can be effectively removed with the เอเจนต์ according to the การประดิษฐ์ without damaging the fabric.
25
Moreover, it is possible to use such acid-adjustedเอเจนต์ for the removal of stains such as rust, blood or contaminants on top of calcifications. Since the acid-
adjusted เอเจนต์ does not attack the fibers, such an
30 เอเจนต์ is suitable for the removal of stains and
deposits in particular on soft sensitive surfaces such
as woven, knitted or fulled fabrics, especially on
textiles, carpets or curtains. The surfaces can be e.g.
made of synthetic or natural fibers, natural or
35 artificial leather or else of plastic.

Moreover, the acid-adjusted เอเจนต์ according to the
การประดิษฐ์ can of course also be used to remove such
stains from hard, insensitive surfaces, for example on
metal, ceramic, stone, glass, plastic or wood.

In a further variant, which is suitable in particular for the removal of colored stains such as, for example,
red wine, the เอเจนต์ ประกอบรวมด้วย bleaches as active
ingredient, for example salts of peracids such as
10 perborates, percarbonates, persulfates or
phthalimidoperoxohexanoic acid (PAP) ที่ควรใช้คือ, the
bleaches are present in a concentration of at least 5%
by weight and ที่ควรใช้คือ of at least 8% by weight and
ที่ควรใช้ เป็นพิเศษคือ at least 12% by weight, in the
15 เอเจนต์. If desired, a bleach activator such as, for
example, tetraacetyleneethylenediamine (TAED), nitrile
quats, NOBS (nonanoyloxobenzenesulfonate) or DOBS
(deecanoyloxobenzenesulfonate), can also be added to
the เอเจนต์.
20
In a preferred variant, the bleach-ซึ่งประกอบรวมด้วย เอเจนต์
ประกอบรวมด้วย at least 20% by weight of สารลดแรงตึงผิว, at
least 10% by weight of bleaches and between 20% by
weight and 60% by weight of สารส่งเสริมการยึดเกาะs as pure
25 substance or as a solution in a hydrophobic solvent and
optionally bleach activators and solubility promoters,
in a particularly preferred embodiment between 25% by
weight and 40% by weight of สารลดแรงตึงผิว, at least 10%
by weight of salts of peroxo acids and between 30% by
30 weight and 50% by weight of สารส่งเสริมการยึดเกาะs, in
particular อัลคิลีน styrene โคโพลิเมอร์ dissolved in
hydrophobic solvents (Versagel).
Such เอเจนต์ are suitable for the removal of red wine, 35 coffee or tea stains from soft sensitive surfaces such
as textiles and carpets, but also for the removal of
57140 Basic.doc

red wine, coffee or tea stains from the aforementioned
hard surfaces.
For this, the เอเจนต์ is applied to the stain on the
5 affected article, if necessary waiting or action times
are observed, and the article is then washed, for
example in a washing machine or else rinsed. In the
presence of the water, the bleaches and the สารลดแรงตึงผิว
are then gradually released from the เอเจนต์ on the stain 10 and bleach the stain and transport the contaminants
away into the wash liquor. Since the active ingredients
are incorporated in the hydrophobic matrix of the
สารส่งเสริมการยึดเกาะ and are only dissolved from this in
the presence of water, overdoses of the active
15 ingredients and therefore damage to the fabric can be
avoided.
In a further variant, the เอเจนต์ according to the
การประดิษฐ์ can be formulated for the removal of fat-
20 soluble and/or pigment-containing contaminants such as
lipstick, shoe cream, cocoa, greases or waxes.
To remove such contaminants, the เอเจนต์ has firstly
hydrophobic organic solvents, which serve to dissolve 25 the greases or waxes. The hydrophobic organic solvents
which serve for this purpose must therefore be freely available in the เอเจนต์. Solvents which are present in the เอเจนต์ but which are required for the gel formation,
such as, for example, the hydrophobic solvents, which 30 function as solvents for the gel formation in the
Versagel particularly preferred as สารส่งเสริมการยึดเกาะ
are not freely available organic solvents in the
context of the การประดิษฐ์.
35 ที่ควรใช้คือ, therefore, hydrophobic organic solvents are
additionally added to the เอเจนต์ via the hydrophobic solvent required for the gel formation, for example
57140 Basic.doc
- 8 -
terpenes, alkanes, mineral oils, long-chain alcohols (R
> 10) , esters or ethers.
In general, the concentration of the free organic
5 solvents in the เอเจนต์ is at least 10% by weight,
ที่ควรใช้คือ above 15% by weight and particularly
ที่ควรใช้คือ between 20% by weight and 40% by weight.
In addition to the freely available organic hydrophobic 10 solvents, the เอเจนต์ should also have alkalis which, on
the one hand, likewise serve to dissolve the greases
and oils. On the other hand, the alkalis also bring
about a swelling of the fibers and thus also facilitate
the active ingredients penetrating sufficiently into 15 the textiles and being able to transport away again
dissolved contaminants as a consequence of the swollen
structure.
The concentration of alkalis in those เอเจนต์ which
20 additionally ประกอบรวมด้วย hydrophobic organic solvents is
generally at least 2% by weight and ที่ควรใช้คือ at least
5% by weight.
Such alkaline-adjusted เอเจนต์ with at least 2% by
25 weight of alkalis, ที่ควรใช้คือ NaOH or KOH, at least 20%
by weight of free hydrophobic organic solvents,
ที่ควรใช้คือ terpenes, at least 10% by weight of adhesion
promoters (ที่ควรใช้คือ อัลคิลีน styrene copolymer,
dissolved in organic solvents such as Versagel) and at
30 least 20% by weight of สารลดแรงตึงผิว are suitable for
removing grease- and/or pigment-containing stains such
as cocoa, lipstick, shoe cream, chewing gum and
turmeric, ที่ควรใช้คือ from soft, sensitive, in
particular textile surfaces.
35
Such an เอเจนต์ can of course also be used for removing stains from hard surfaces.
57140 Basic.doc

In a further variant, the เอเจนต์ is formulated with a
very high fraction of alkalis, which is generally above
50% by weight and ที่ควรใช้คือ above 60% by weight. Such
5 adhesive, pasty, strongly alkaline เอเจนต์ stick to
vertical surfaces and release the alkalis in the
presence of water, for example as a result of flushing,
and these then attack deposits of resins, greases, oils
or the like. Such เอเจนต์ can be used for example in
10 industrial plants and combustion chambers in order to
remove flue gas resins, grease- or oil-containing
contaminants or soot. Such a strongly alkaline เอเจนต์
exhibits very good results when removing resin or
grease deposits even on vertical surfaces (e.g. in
15 furnacco slaughter-houses, in pipe blockages of greases
(drain-opener), for the removal of keratin substances
(hair, horn)) For the cleaning of sensitive soft
surfaces, by contrast, such a strongly alkaline เอเจนต์
is only suitable in exceptional cases, e.g. for fabric
20 made of alkali-resistant fibers such as Teflon or PUR.
สารลดแรงตึงผิว
The เอเจนต์ according to the การประดิษฐ์ ประกอบรวมด้วย
25 สารลดแรงตึงผิว, where anionic, cationic, nonionic and
amphoteric สารลดแรงตึงผิว can be used as สารลดแรงตึงผิว.
The สารลดแรงตึงผิว serve i
