Definitions

• the present invention relates to a low-water preparation suitable for spreading on textile substrates.
• preparations containing active ingredients are applied locally to the substrates to be treated, so that the active ingredients on the substrates can develop their effect.
• Such preparations are, for example, emulsions, solutions, dispersions, optionally in the form of ointments, creams or pastes. They are used e.g. in the cosmetic, pharmaceutical or printing technology sector or also in the cleaning or laundry industry or in the household and generally serve for the local application of active ingredients. Because of their easy handling, especially when dosed, pastes or creams are particularly popular with the user.
• the pastes generally contain active substances or auxiliary substances, the viscosity of which is very dependent on the temperature; at low temperatures they are semi-solid to solid, at higher temperatures they become liquid to thin. For storage, transportation and the use of preparations which, because of their content of such constituents, have a strong viscosity / temperature dependence, this property can be a considerable disadvantage in some cases. It is therefore endeavored to give the pastes a consistency which ensures problem-free handling.
• the person skilled in the art has thickeners and diluents available with which the consistency can be influenced. While the diluents are generally organic solvents or water, thickeners are inorganic or organic compounds which belong to a wide variety of substance classes. They increase or decrease the viscosity of the pastes or give them pseudoplastic properties. They often act either only in aqueous or only in non-aqueous systems and influence the viscosity / temperature dependency only inadequately or not at all.
• the object of the present invention is therefore to provide a low-water, pasty agent for spreading on textile substrates with the aim of completely or largely eliminating its viscosity / temperature dependency.
• the term "low in water” is intended to mean a water content of at most 10 percent by weight.
• Low water should also include “water-free” in the sense that no water is added to such an agent and therefore it contains at most as much water as can get into the agent through the optionally used water-containing components.
• an agent containing a combination of a thickener and a diluent comprising fatty acid alkanolamides, fatty acid esters, fatty alcohol ethoxylates and polyacrylic acid derivatives and the diluent comprising mono- or polyhydric alcohols having 1 to 6 carbon atoms and / or liquid hydrocarbons and the weight ratio from thickener to diluent is 1: 6 to 6: 1.
• Fatty acid alkanolamides which are suitable for the purposes of the present invention are, for example, di- or preferably monoethanolamides which are derived from fatty acids or fatty acid mixtures with preferably 10 to 20 carbon atoms.
• the fatty acids can be straight-chain or branched and saturated or mono- or polyunsaturated.
• Typical representatives of the class of compounds mentioned are the preferably used stearic acid monoethanolamide and coconut fatty acid ethanolamide.
• Suitable fatty acid esters are esters of fatty acids or fatty acid mixtures with preferably 10 to 20 carbon atoms with mono- or polyhydric alcohols with 1 to 5 carbon atoms.
• the fatty acid component of the esters is the same as that of the fatty acid ethanolamides.
• the alcohol component is either branched or straight-chain and is derived, for example, from ethanol, isopropyl alcohol, glycerol, ethylene glycol, diethylene glycol or pentaerythritol.
• Typical fatty acid esters are the preferred glycerol monostearate, ethylene glycol monostearate, ethylene glycol distearate and mixtures thereof.
• suitable fatty alcohol ethoxylates as to the fatty acids.
• Fatty alcohol ethoxylates suitable as thickeners contain at least about 20 moles of ethylene oxide per mole of fatty alcohol.
• An example of suitable compounds of this class is cetyl / stearyl alcohol, to which 30 moles of ethylene oxide are attached.
• Fat derivatives suitable as thickeners in the context of the present invention are also to be understood as the reaction products of fats with hydroxyalkyl polyamines known, for example, from DE AS 19 22 047.
• polyacrylic acid derivatives which are also suitable as thickeners are water-soluble compounds with a molecular weight between approximately 400,000 and 4,000,000. They can be used in acid form or as salts and are commercially available under the name "Carbopol” ®, company BF Goodrich .
• Diluents in the sense of this invention are monohydric or polyhydric alcohols with 1 to 6 carbon atoms and liquid hydrocarbons or hydrocarbon mixtures with 6 to 40 carbon atoms; the alcohols and the hydrocarbons can be used either individually or in combination. Mixtures of noncyclic compounds, in particular isoparaffins, are preferred as hydrocarbons.
• the agent according to the invention preferably contains components of textile detergents.
• Washing aids can be applied, for example, to stained or heavily soiled items of laundry and improve the cleaning performance of the actual detergents in the subsequent washing process.
• Washing aids of this type contain at least two customary components of textile detergents.
• Typical components of textile detergents are, for example, nonionic, anionic, cationic or zwitterionic surfactants, nitrogen-containing detergent boosters, bleaching agents, bleach activators, water-soluble or water-insoluble builder substances, heavy metal complexing agents, foam regulators, graying inhibitors, fabric softeners, dyes, fragrances, enzymes.
• preparations which contain nonionic surfactants in combination with further detergent constituents can be improved with regard to the viscosity / temperature behavior by the combination according to the invention.
• Suitable alcohols are ethanol, propanol, butanol, ethylene glycol, diethylene glycol, propylene glycol, diacetone alcohol or glycerol or mixtures thereof, a mixture of mono-, di- and trihydric alcohols being preferred.
• fatty acid esters for example ethylene glycol mono- and / or distearate
• thickeners for example ethylene glycol mono- and / or distearate
• Pasty compositions which contain 5 to 20 percent by weight of thickeners, in particular a combination of polyacrylic acid derivative and fatty acid ester and 30 to 60 percent by weight of diluents, in particular liquid hydrocarbons, are also preferred.
• the polyacrylic acid derivatives suitable as thickeners are salts, in particular amine salts.
• the salts are formed either by adding the thickener and the salt-forming basic component to the system to be thickened, or by pre-salting with the salt-forming component the addition to the system to be thickened.
• Water-free or largely water-free systems can be thickened well with amine salts, while noticeable amounts of water-containing preparations (up to 10% by weight) can be thickened well with alkali salts.
• Combinations of polyacrylic acid with quaternary ammonium compounds, such as in particular tetradecyl or cetyltrimethylammonium bromide are also suitable for thickening preparations with a water content of up to about 10 percent by weight.
• the polyacrylic acid salt of fatty amines for example coconut alkyl amine, in particular that of polyacrylic acid and that of the adduct of 2 moles of ethylene oxide with coconut alkyl amine, has proven particularly useful. Good results are also achieved with higher ethoxylated fatty amines or with non-ethoxylated fatty amines with 10 to 20 carbon atoms.
• a polyacrylic acid derivative in combination with one of the fatty alkyl derivatives already mentioned as thickeners, in particular with a fatty acid ester is particularly preferred.
• High molecular weight polyacrylic acid derivatives are preferred in the context of this invention, i.e. those polymers which have a molecular weight of at least 500,000, in particular of at least 1,000,000 and preferably of about 4,000,000.
• Such a polyacrylic acid derivative is, for example, the commercial product "Carbopol 940®" from B.F. Goodrich, United States.
• Preparations whose viscosity is regulated by a combination of a polyacrylic acid derivative with a cationic surfactant as a thickening component and with liquid hydrocarbons as a diluting component have interesting rheological properties.
• Preparations according to the invention are suitable, for example, as laundry pretreatment agents with which heavily soiled textiles or parts of textiles, such as e.g. Collar edges can be pretreated to enhance the washing effect of the wash liquor during a subsequent wash.
• Such preparations therefore contain cleaning, dissolving or bleaching components of the type described above.
• Good results are obtained with preparations which contain at least one nonionic surfactant and one cationic surfactant.
• Suitable nonionic surfactants include, in particular, addition products of ethylene oxide with fatty alcohols or, in particular, oxo alcohols with 12 to 18 carbon atoms.
• Particularly suitable surfactants are derived from alcohols with 14 to 15 carbon atoms.
• oxo alcohol ethoxylates which contain 3 to 10, preferably 6 to 8 and in particular about 7 moles of ethylene oxide per mole of alcohol.
• foam regulators are, for example, the known silicone oils.
• the nonionic surfactant content of the paste promotes the removal of greasy or oily soiling during washing.
• Suitable cationic surfactants contain long-chain alkyl or alkenyl radicals with 10 to 20, preferably alkyl groups with 10 to 16 and in particular about 14 carbon atoms.
• the suitable quaternary ammonium compounds contain 3 identical or different alkyl groups with 1 to 4 carbon atoms.
• these short alkyl groups are methyl groups.
• a particularly good quaternary ammonium compound is tetradecyltrimethylammonium bromide, which can also be used to enhance the thickening effect of polyacrylic acid derivatives in very low-water preparations.
• Another agent contains at least one nonionic surfactant of the aforementioned type and a bleach activator for per compounds.
• activators for per compounds are N-acyl and O-acyl compounds. Examples of this are tetraacetylglycoluril or pentaacetylglucose or in particular tetraacetylethylenediamine.
• the bleach activators mentioned lead to improved removal of bleachable textile soiling.
• preferred laundry pretreatment agents according to the invention contain both a nonionic surfactant, a cationic surfactant and a bleach activator of the type described above.
• the viscosity of particularly effective and therefore preferred agents is regulated by the use of a thickener consisting of a polyacrylic acid derivative and a fatty acid derivative, preferably a fatty acid ester Combination in which the polyacrylic acid derivative has a molecular weight of at least 500,000, preferably at least 1,000,000 and in particular approximately 4,000,000 and a diluting mixture of propylene glycol, glycerol and ethanol.
