The present invention relates to certain new
aerosol formulations based on water, to a procPss for
their preparation and to their use in the domestic field
and hygiene field and in plant protection.
The application of active compounds in the domestic
field and hygiene field and in plant protection with the
aid of spray cans in which the active compounds in the
aerosol formulations are contained in solution in organic
solvents has already been disclosed. In this type of
application relatively large amounts of organic solvents
are sprayed; this is expensive, on the one hand, and is
also undesirable for reasons of environmental protection, on
the other hand. To eliminate this negative factor as far
as possible, aerosol formulations were therefore developed
in which a part of the organic solvents is replaced by
water. A decisive disadvantage of the previously dis-
closed aerosol formulations of this type however is that
they exhibit a significantly lower action than the corres-
ponding water-free aerosol formulations (see
Bundesgesundheitsblatt tFederal Health Sheet) 24, No. 10.
pages 163-165 (1981)).
According to the present invention we provide, as
new formulations, aerosol formulations based on water,
characterised in that they consist of
0.01 to 6~o by weight of at least one insecticidal and/
or acaricidal substance selected from
carbamates, pyrethroids, acetic acid ester
derivatives and phosphoric acid ester derivatives,
0.1 to 2~o by weight of at least one emulsifier,
to 40O by weight of at least one organic solvent,
to 70O by weight of water,
_ 10 to 50O by weight of propellant and
if appropriate, 0.1 to 6~ by weight of
additives,
the sum of the components being 100,~ by weight in each case.

According to the present invention we further provide
a process for the production of an aerosol formulation of
the present invention, characterised in that a solution
consisting of
û.01 to 62~ by weight of at least one insecticidal and/or
acaricidal substance selected from carbamates,
pyrethroids, acetic acid ester derivatives and
phosphoric acid ester derivatives,
0.1 to 2Co by weiyht of at least one emulsifier,0 5 to 40~ by weight of at least one organic solvent
and
if appropriate, 0.1 to 6o by weight of
additives,
is mixed with 20 to 7030 by weight of water, and lO to 50O
by weight of propellant is added to the resulting mixture
in a spray can, the sum of the components in the formul-
ation being lOO~o by weight in each case, and the percentages
by weight being relative to the resulting formulation.
Finally, it has been found that the aerosol formul-
ations, according to the invention, based on water, can beused in the domestic field and hygiene field or in agri-
culture and in horticulture.
It i9 to be regarded as extremely surprising that
the aerosol formulations, according to the invention,
which are based on water and contain insecticidal and/or
acaricidal substances selected from carbamates, pyrethroids, acetic
acid ester derivatives and phosphoric acid ester derivatives,
possess a better action than the corresponding, previously known
water-free aerosol formulations. A superior action of this type
could not be expected on the basis of the known state of the art,
since, according to previous experience, the water-free
aerojol formulations exhibited in each instance a better
activity than the analogous water-containing aerosol
formulations.
However, the aerosol formulations, according to the
invention, based on water, are distinguished in comparison
Le A 21 105
117496~
to the corresponding, previously known water-Free aerosol
formulations not only by an unexpectedly higher action, but
also by the fact that a smaller amount of organic solvent is
required. The aerosol formulations, according to the
invention, based on water, can therefore be prepared more
cheaply than the corresponding water-free aerosol formul-
ations. In addition, the pollution of the environment
by organic solvents is reduced in the case of the aerosol
formulations according to the invention.
The aerosol formulations, according to the present
invention, based on water, contain at least one insecti-
cidal and/or acaricidal substance selected from carbamates,
pyrethroids, acetic acid ester derivatives and/or phosphoric
acid ester derivatives. The following may be mentioned as
individual examples of active compounds of this type:
2-isopropoxy-phenyl N-methylcarbamate, 2,2,2-
trichloro-1-(3,4-dichlorophenyl)-ethyl acetate, ~-cyano-m-
phenoxybenzyl (1R, 3R)-3-(2,2-dibromovinyl)-2,2-dimethyl-
cyclopropane-1-carboxylate, 2,3,4,5-tetrahydrophthalimido-
methyl chrysanthemumate, ~-cyano-3-phenoxy-4-fluorobenzyl
3-(2,2-dichlorovinyl)-2,2-dimethyl-cyclopropane-carboxylate,
(pentafluorophenyl)-methyl 3-(2,2-dichlorovinyl)-2,2-
dimethyl-cyclopropane-carboxylate, natural pyrethrum,
0,0-diethyl thionophosphoryl-a-oxlmino-phenyl acetic acid
nltrile and 0,0-diethyl thionophosphoryl-X-oximino-
(2-chlorophenyl)-acetic acid nitrile. 2-isopropoxy-phenyl
N-methylcarbamate is particularly preferred.
Polyoxyethylenesorbitane fatty acid ester and
sorbitane fatty acid ester are preferred as emulsifiers
which are contained in the aerosol formulations according
to the invention. The following may be mentioned as
examples: polyoxyethylene-sorbitane monolaurate,
monopalmitate, monostearate and monooleate, having in each
case an average of 20 -~H2-CH2-0 groups per molecule, and
also sorbitane monolaurate, monopalmitate, monostearate,
tristearate, monooleate and trioleate.
The emulsifiers can be contained individually or
in the form of mixtures in the aerosol formulations
Le A 21 105

according to the invention.
The following are preferred as organic solvents
which are contained in the aerosol formulations according
to the invention: saturated aliphatic hydrocarbons of
boiling point between 150C and 250C (such as dodecane
and deodorised kerosenes), ~d ~so low-boiling chlorinated aliphatic
hydrocarbons (such as methylene chloride~ and furthermore
alcohols having up to 3 carbon atoms (such as ethanol,
n-propanol and iso-propanol) and in addition, low-boiling
ketones (such as acetone and methyl ethyl ketone).
The organic solvents can be contained individually
or in the form of mixtures.
Distilled w~t-r is preferred as the water in the
case of aerosol formulations according to the invention.
Mixtures of propane and butane are preferred as
propellants which are contained in the aerosol formuiations
according to the invention.
Synergists, aroma substances and stabilisers are
suitable as additives which can be contained in the
2û aerosol formulations, according to the invention, based
on water.
Piperonyl butoxide may be mentioned as an example
of a synergist.
Perfume oils are suitable as aroma substances.
The aroma gubstance obtainable under the designation
"FrischduFt 760 712 H + R!' from Haarmann & Reimer GmbH,
Holzminden, may be mentioned in particular.
Sodium benzoate and amphoteric tensides may be
mentioned as examples of stabilisers.
The percentage proportions of the components
contained in the aerosol formulations, according to the
invention, based on water, can be varied within the
specified ranges. The proportion of active compound
or active compounds is preferably between 0.04 and 3O by
weight. The proportion of emulsifier is preferably 0.2 to
Le A 21 1û5
.
1 17496~
1.5~o by weight. Organic solvents are present preferably
in proportions between 6 and 35O by weight. The pro-
portion of propellant is preferably between 20 and 40O by
weight. Additives can be contained in proportions of
preferably 0.5 to 5O by weight.
The percentage proportion of water in the aerosol
formulations according to the invention is calculated in
each cass as the difference between 100~o by weight and the
sum of the percentage portions of the remaining components.
Preferably between 30 and 65~ by weight, of water are
contained in the formulations.
In the preparation of the aerosol formulations,
according to the invention, based on water, by the process
according to the invention, all those components can be
used which have already been mentioned in connection with
the description of the aerosol formulations themselves.
Those substances which have been mentioned individually
above as preFerred or as examples are preferred.
In carrying out the process according to the
2û invention, the process temperatures can be varied within a
certain range. The process is carried out in general
at a teMperature between 0C and 50C, preferably between
10C and 30C.
In carrying out the process according to the
invention, in general the following procedure is followed:
a solution of the active compound or active compounds,
emulsifier and organic solvent and, if appropriate, additives,
is introduced into a spray can which already contains the
desired amount of water, the spray can is then closed with
a valve, and the propellant is introduced by customary
methods. The sequence in which the components are combined
in the preparation of the organic phase is variable. Like-
wise, the mixing of the organic phase with water and the
addition of a propellant in a customary manner can also be
varied.

The aerosol formulations, according to the
invention, based on water, can be applied in the
prepared form. The amount used depends on the con-
centration in which the active compound is present, and
on the particular indication.
The present invention also provides a method of
combating insects or acarids which comprises applying to
the insects or acarids, or to a habitat thereof, an
aerosol formulation of the present invention.
The present invention also provides a method of
freeing or protecting domesticated animals from insects or
acarids which comprises applying to said animals an
aerosol formulation according to the present invention.
The present invention further provides crops
protectsd from damage by insects or acarids by being grown

a harvested crop may be improved by the present invention.
The present invention further provides domesticated
animals whenever freed or protected from insects or acarids
by the application to said animals of an aerosol formulation
according to the presnt invention.
Furthermore, it is possible to spray other areas
or objects on which the active components are to develop
their action with the formulations. If the active
components are intended to act in rooms, the formulations
are sprayed in these rooms.

biotest-Examples.
Example A
Aerosol test
Test animals: Musca domestica 0~ (resistant)
3 wire cages were suspended from the ceiling in
two identical rooms A and B of 30 m~ capacity each, and
20 3 to 4 day old flies of the species ~lusca domestica
were introduced into each wire cage so that there were 60
flies in each room.
The room temperature is 22C in both rooms.
Through a flap in the doors to both rooms, 16.9 9 of the
formulation of Example 14 were then sprayed into r~om A
and 16.9 9 of the formulation of Example 1 were sprayed

into room B. Thereafter,the condition of the test
animals was constantly checked from outside, through a
glass window, and the times (minutes) required for a 50O
(k.d. 50) or 100o (k.d. lO0) knock-down effect on the
flies were determined.
The values determined can be seen in Table A

Aerosol te~t
Test animals; l~usca domestica ~ (resistant)
3 wire cages were suspended from the ceiling in
each of three identical rooms A, B and C of 30 m3 capacity,
before each sxperiment. Each wire cage contained 20 3 to
4 day old flies. The temperature in the rooms ~as 22C.
16.9 9 of can content per ro-om were sprayed successively
into the rooms from spray cans, through a flap in the door.
The condition of the test animals was constantly checked
through a window in the door, and the times (minutes)
required for a 50O (K.d. 5û) and a 100~o (K.d. lO0) knock-
down effect on the flies were determined. In this
manner several spray can formulations were tested in
succession. Between the individual tests, the rooms were
thoroughly ventilated until they were again insecticide-
free.
