For example, when dyeing or finishing Textile material! En air from the interim councils of textile material through the dye liquid or the finishing liquid be completely displaced. Lots of textile materials, in particular those made from synthetic polymers are hydrophobic and, in terms of their ability, being wetted with water behaves similarly to paraffin wax. Therefore it is often necessary to have the wetting properties the bath fluids to improve to a satisfactory To achieve coloring or finishing.

Similarly, there is often a tendency during drying following a dyeing process that the Dyebath liquid still clinging to the textile material too migrates to the side of the textile material from which the evaporation of the water predominantly takes place. This migration carries with it a certain amount of dye and creates a two-sided effect in the finished item. Sine improvement in Reduced wetting properties of the dye bath liquid this effect. Other inhomogeneous coloring effects, such as coldness, are also reduced.

Another technical area is glazing on ceramic Substances made with resinous transfer materials are decorated. This often results in a rough surface due to the incomplete wetting of the hydrophobic over.gun.score surface. Smoothness. Surfaces can be obtained by measuring the wetting properties of the

In agriculture, materials such as pesticides are used or spraying fungicide onto the foliage of plants in the form of an aqueous dispersion or solution or applied to seeds by Taurcel & isehen! The effectiveness of these materials generally depends on the extent the spread over the surface of the foliage or the seeds and thus also the wetting properties the dispersion or solution.

Furthermore, the behavior of a number of active ingredients, such as dyes and agricultural "chemicals, for example, depends on the Achieving a fine dispersion of these substances in water before use. A complete displacement of the air by water of powders made from such materials is an essential Requirement for good dispersion and will supported by the combination of anionic or cationic agents with an ethylene oxide condensate. With a "Active ingredient" means any material or combination of materials that is applied to the surface a solid substrate is to be applied, do the Properties of the substrate or the surface of the substrate to influence.

'As active ingredients are to be named here, for example; ! Textile lubricants, Spinnappretüren, antistatic agents, plasticizers _s optical brighteners, paper treatment materials, electro-conductive agents for reprographic papers, detergents and additives that Schmützwiederabscheidung preventing systems Metairbehandlungsverbindungen. Pickling agents, reading vagaries, anti-corrosion agents, film-forming polymers, such as emulsion paints, polishes, pottery glazes, bio-silk and especially agricultural chemicals,

409819 / 11S6

especially herbicides, fungicides or pesticides

The extent to which wetting has occurred after application of an aqueous composition to a solid can be determined in various ways, the usefulness of which varies from case to case.

The simplest determination in the case of a solid surface happens by observing the extent to which the spread is taking place. A quantitative measurement of the Ability to spread can be obtained through the "contact angle" when the spread is incomplete. Of the Contact angle is the angle between the contact surface the solid surface with the composition and the tangent to the drops of an aqueous composition at the point where it_ touches both the solid surface and the air, is included. A low contact angle shows better wetting than a large square. He is through a low surface tension of the aqueous composition favors. ,

The degree of suitable wetting is in many textile Processing operations that amount of the aqueous composition, expressed as a percentage by weight based on the Textile material which passes through the textile material after passage through a bath containing the aqueous composition, and then held between block rollers.

Examples of cationic surfactants are qua— ternary salts, such as alkyltrimethylammonium halides, alkylbenzyldimethylammonium halides, alkylpyridinium halides, . Alkyl quinoline halides, alkyl imidazolinium halides genides and alkyl rorpholine halides and preferably Alkyl trimethyl ammonium halides and alkyl pyridinium halides with S to 18 carbon atoms in the alkyl group.

The agent can be a set of agents having a range of alkyl chain lengths.

Examples of anionic surfactants are alkyl- sulfates, such as liatrium dodccyl sulfate, optionally substituted aromatic sulfonates, such as sodium dodecylb'onzenesulfonate, Ivatriura naphthalene sulfonate, sodium oleyl panisidine sulfonate, Sodium dibenzyl sulfanilate, the sodium salt of the condensation product of isopropanol with naphthalene-2-sulfonic acid., the sodium salts of condensates of aidehydes, such as formaldehyde, with aromatic sulfonic acids, like z.E. Iaphthalene-2-sulphon acid, lignosulphonates and sulphated natural oils, such as sulphated castor oil, sulfated Sp.eraöl or sulfated Kethyloleate. The preferred Anionic gowns are salts of alkylbenzenesulfonic acids and formaldehyde / waphthalenesulfonic acid condensates.

Mixtures of cationic or. Mixtures of anionic surface Surface active agents can also be used. The choice of cationic or anionic surfactants Agent may depend on other components of the aqueous composition. For example, if the aqueous composition contains an active ingredient that is a great organic Has anion, then it is desirable to be an anionic surfactant Means to use to prevent precipitation that. obtained by a combination of the anion of the active ingredient with a surface-active cation and vice versa v / ird.

The alcohol from which the ethylene oxide condensate is derived preferably contains an alkyl group which is straight-chain or only slightly branched, by which it is meant that it is not contains more than one tertiary carbon atom. As such Alcohols should be mentioned, for example, octanol, decanol, dodecanol and alcohols that are produced by carbonylation of

Olefins are obtained from petroleum fractions. Examples of the latter are the Gr _7- O-Alcohols with about 45 % Cn-, 40 % C ₈ - and 15 % Cn alcohols, and C ^ ,,,, - alcohols, which are about 20% Cq-, 4 Contains -5 % ^c io ~ ^and ^ ^ C ^ alcohols.

Mixtures of ethylene oxide condensates can also be used will. The preferred condensates contain 2 to 3 nolar Proportions of ethylene oxide.

The ratio of the total amount of cationic or anionic see surface-active agents on the total amount of ethylene oxide condensates can be changed within very wide limits, but is usually within a range of 1: 3 to 20: 1.

The amounts of surface-active. Agents and ethylene oxide densateh together can vary within wide limits The preferred kengen usually depend on the amount and type of active ingredient and the surface on which he should be applied from.

Aqueous compositions suitable for application to surfaces normally contain only small Kengen actives, such as 0.01 to 5.0 #, although amounts outside this range may be used in some cases and amounts of surfactant and ethylene oxide condensate taken together OiOOtJS can give adequate melting properties. The preferred amounts in such compositions are 0.01 to 5.0 %. Larger sizes can also be used, although this usually does not provide a corresponding benefit.

However, E3 is often useful, aqueous compositions that are more concentrated and that contain more than 20 #

The above ready-to-use compositions, the concentrates and medium concentration aqueous compositions represent all aspects of the invention.

Optionally, the aqueous compositions, in particular the concentrates, by drying using an appropriate method, in particular spray drying, in powder be convicted. Such powders, which are easily stored, handled and "transported," represent another manifestation of the invention.

The aqueous compositions can optionally also contain other additives, such as corrosion inhibitors.

The aqueous compositions of the invention can by any convenient method suitable for the particular composition can be prepared, for example by having the ingredients in any desired Mixes sequence at a .practical temperature, usually room temperature. If necessary, can higher temperatures are used to improve the mixing process to support »As the surface active agent and the ethylene oxide condensate often do the dissolution or dispersion facilitate the use of the active ingredient, it is often

Mixing with only a small amount of water to achieve a concentrated aqueous composition which can be diluted as desired, often represents the most expedient procedure.

The aqueous compositions of the invention have excellent ones Wetting properties for surfaces that are normally difficult to wet, such as certain types of foliage, for example black foxtail or barley, certain textile materials with hydrophobic surfaces, such as e.g. synthetic materials, e.g. polyamides and polyester, or uncleaned wool or cotton, textiles, whose wettability is further limited by their construction, such as crimped polyester, knitted fabrics, and long pile carpets, oily or greasy materials, plastics, dirty glass or dirty ceramics and resin-coated ceramics. Additionally . the aqueous compositions can have increased fluidity compared to similar aqueous compositions, which do not contain both a surface-active agent and an ethylene oxide condensate.

According to the invention, a method for applying active ingredients to substrates is also proposed, which thereby , is carried out that the surfaces of the substrate are treated with an aqueous composition according to the invention.
