Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a low water content paste preparation suitable for coating on a fiber substrate.

BACKGROUND OF THE INVENTION Preparations containing active substances are often applied locally to the substrate to be treated so that the active substance can develop its effect on the substrate. Such preparations are, for example, in the form of emulsions, solutions, dispersions, and optionally ointments, creams or pastes. They are used, for example, in the cosmetic, pharmaceutical or printing fields, or even in the cleaning or laundry field, or even in the home, and are generally used for the topical application of active substances. In many cases, pastes or creams of 6 are popular among users due to their ease of handling, especially when applied with a dispenser. The following description is
In particular for pastes or creams or gels, but injectable liquid preparations are not excluded. In the following, all these formulations are referred to as pastes or pasty formulations. They are active locally and also in areas other than the usual site when dispersed, for example in a bathtub.

Pastes generally contain active substances or auxiliaries whose viscosity is highly dependent on temperature. At low temperatures, they
It is semi-solid to solid, and liquid to dilute liquid at relatively high temperatures. The second characteristic can be a disadvantage, for example in the storage, transport and application of formulations whose viscosity is highly temperature dependent due to the presence of the above-mentioned components. Therefore, various efforts have been made to give pastes a consistency that is easy to handle. For this purpose, thickeners and diluents that can affect consistency are commercially available.

Diluents are generally organic solvents or water, and thickeners are various types of inorganic or organic compounds. They increase and decrease the viscosity of the paste and give it grooved viscous properties.

In many cases they act only in aqueous or non-aqueous systems and have little, if any, influence on the temperature dependence of viscosity.

OBJECT OF THE INVENTION An object of the present invention is to provide a low water content paste preparation for application to fiber substrates in which the temperature dependence of viscosity is completely or almost eliminated. In the present invention,
The expression "low water content" means that the water content is at most 10% by weight. "Low water content" also refers to "anhydrous" in Hikomi, where no water is added to the formulation and it contains at most water from the optional aqueous component. DISCLOSURE OF THE INVENTION] According to the present invention, the above object is to provide a low water content paste preparation for coating fiber substrates containing a combination of a thickener and a diluent, the thickener being a fatty acid alkanolamide. , fatty acid esters, fatty alcohol ethoxylates and/or polyacrylic acid derivatives, monohydric or polyhydric alcohols containing q to 6 carbon atoms and/or liquid hydrocarbons, This is achieved by a formulation characterized in that the weight ratio of thickener to diluent is between 120 and 6;1.

The effectiveness of these combinations according to the invention is surprising since thickeners or diluents alone do not have any influence on the viscosity/temperature behavior.

Fatty acid alkanolamides suitable for the purposes of the invention are, for example, jetanolamides, preferably monoetamolamides, derived from fatty acids or fatty acid mixtures, preferably containing 10 to 20 carbon atoms. The fatty acid may be linear or branched, homogeneous, mono- or polyunsaturated. Typical examples of the FrL compounds are preferably stearic acid monoethanolamide, coconut oil and fat, and stearic acid ethanolamide.

Suitable fatty acid esters are preferably fatty acids or fatty acid mixtures containing 10 to 20 carbon atoms and 1 to 5 carbon atoms.
esters with monohydric or polyhydric alcohols containing 5 carbon atoms. The fatty acid component of the ester is the same as that of the fatty acid ethanolamide. The alcohol component may be branched or linear and is derived from, for example, ethanol, isopropyl alcohol, glycerol, ethylene glycol, diethylene glycol or pentaerythritol. Typical fatty acid esters are preferably glycerol monostearate, ethylene glycol monostearate, ethylene glycol distearate and combinations thereof.

For alkyl chains, the same is true for fatty acids.
This also applies to the preferred fatty alcohol ethquinate.

Fatty alcohol ethoxylates suitable as thickeners are
Contains - at least about 20 moles of ethylene oxide per mole of fatty alcohol. An example of a suitable compound of this type is cetyl/stearyl alcohol to which 30 moles of ethylene oxide are added. It is important for all thickening fat derivatives to have a melting point of 40°C or higher.

Other fat derivatives which are preferred as thickeners for the purposes of the present invention are described in the West German published patent DE-AS +9 220
It is a reaction product of a fat and a hydroxyalkyl polyamine as disclosed in No. 47.

Polyacrylic acid derivatives suitable as thickeners are water-soluble compounds having a molecular weight of about 400,000 to about 4,000,000. They may be used in acid form or as salts and are available in the form of “Carbopol® J(B,
It is commercially available under the trade name of F., a product of Goodrich.

Suitable diluents for the purposes of the invention are monohydric or polyhydric alcohols containing from 1 to 6 carbon atoms, and may also be liquid hydrocarbons or hydrocarbon mixtures containing from 6 to 40 carbon atoms. Alcohols and hydrocarbons may be used individually or in combination. Mixtures of acyclic compounds, especially isoparaffins, are preferred as hydrocarbons.

The formulations of the invention preferably contain textile cleaning ingredients. In this way, a textile detergent paste with a controlled viscosity or a pasty cleaning aid which enhances the effectiveness of detergents is obtained. Cleaning aids may be applied, for example, to stained or heavily soiled laundry, increasing the cleaning effectiveness of the detergent itself during the subsequent cleaning process. Such cleaning aids contain at least 62 typical textile detergent ingredients. Typical ingredients of textile detergents are, for example, nonionic, anionic, cationic or zwitterionic surfactants, nitrogen-containing detergency enhancers, bleaches, bleach activators, water-soluble or water-insoluble building blocks. , heavy metal complexing agents, foam control agents, anti-redeposition agents, fabric softeners, dyes, perfumes, and enzymes. The viscosity/temperature behavior, especially of formulations containing nonionic surfactants in combination with other detergent ingredients, is improved by the combination formulations of the invention.

In particular, good results are obtained by adding 20-40% by weight of low molecular weight alcohols, based on the final formulation, together with 5-25% by weight of thickeners, especially polyacrylic acid derivatives and fatty acid esters in combination. . Suitable alcohols are ethanol, propatool, butanol, ethylene glycol, diethylene glycol, propylene glycol, diacetone alcohol or glycerol, or mixtures thereof, with mixtures of monohydric, dihydric and dihydric alcohols being preferred.

In some cases it is best to use only fatty acid esters, such as ethylene glycol mono- and/or distearate, as thickeners.

Particularly good results are obtained both with a combination of low molecular weight alcohols and liquid hydrocarbons and with liquid hydrocarbons alone as diluents.

Preferred are paste preparations containing a thickener, especially a combination of a polyacrylic acid derivative and a fatty acid ester, in an amount of 5 to 20% by weight, and a diluent, particularly a liquid hydrocarbon, in an amount of 30 to 60% by weight.

Polyacrylic acid derivatives suitable as thickeners are salts, especially amine salts. Salts are formed by adding thickeners and basic salt-forming components to the system to be thickened, or by rising to the salt-forming components to complete salt-forming prior to addition to the system to be thickened. .

Although anhydrous or substantially anhydrous systems are effectively thickened by amine salts, formulations containing significant amounts of water (up to 10% by weight) are also effectively thickened by alkali salts. A combination of polyacrylic acid with a quaternary ammonium compound such as, for example, especially tetradecyl or cetyltrimethylammonium bromide is suitable for thickening formulations containing up to about 10% by weight of water.

In the case of anhydrous systems, polyacrylates of fatty amines, such as cocosalkylamines, especially salts from polyacrylic acid and a 2-mole adduct of cocosalkylamines with ethylene oxide, have proven particularly effective. Good results are also obtained with relatively highly ethoxylated fatty amines and non-ethoxylated fatty amines containing 10 to 20 carbon atoms.

A combination of a polyacrylic acid derivative and one of the above-mentioned fatty alkyl derivatives as a thickener, especially a fatty acid ester, is particularly preferred because of its excellent thickening effect. According to the invention,
polymeric polyacrylic acid derivatives, i.e. having a molecular weight of at least 6,500,000, preferably at least 1,000;
000 and more preferably less (about 4,000,000
It is preferred to use polymers of One such polyacrylic acid derivative is, for example, "Carbobol 940" from Gudridge, B.F., USA.

With a formulation whose viscosity is controlled by the combination of a polyacrylic acid derivative, a cationic surfactant as a thickening component, and a liquid hydrocarbon as a diluting component,
It exhibits interesting rheological properties.

The formulation of the present invention is suitable, for example, as a textile pre-treatment formulation for pre-treating heavily soiled textile products or parts of textile products, such as collars, in order to enhance the cleaning effect of the cleaning liquid in the subsequent cleaning process. It is. Such formulations therefore contain cleaning, dissolving or bleaching ingredients of the type mentioned above. Good results are obtained with formulations containing at least one nonionic surfactant and a cationic surfactant. Preferred nonionic surfactants include, among others:
Ethylene oxide adducts of fatty alcohols, especially 1
Oxoalcohols containing 2 to 18 carbon atoms. Particularly preferred surfactants are derived from alcohols containing 14 to 15 carbon atoms. alcohol 1
Best results are obtained with oxoalcohol ethoxylates containing 3 to 10 moles of equilene oxide per mole, preferably 6 to 8 moles, more preferably 7 moles. In many cases it is advisable to add foam control agents. Generally foaming should be prohibited. Preferred foam control agents are:
For example, the known silicone oil. The presence of nonionic surfactants in the paste improves the removal of fatty or oily soils, especially during cleaning. Preferred cationic surfactants are CIO to Cto alkyl or alkenyl groups, preferably containing 10 to 16 carbon atoms, more preferably about 111 carbon atoms. Other preferred examples include quaternary ammonium compounds containing three O1-C4 alkyl groups, which may be the same or different.

These short alkyl groups are especially methyl groups. A particularly preferred quaternary ammonium compound is tetradecyltrimethylammonium bromide, which can be used to improve the thickening effect of polyacrylic acid derivatives in very low water content formulations.

Another embodiment of the formulation contains at least one nonionic surfactant of the type described above and a bleach activator for the per-compound. N-decyl and 0-acyl compounds are preferred as activators for per compounds. Examples of such compounds are tetraacetylglycoluril, pentaacediglucose and especially tetraacedelethylenediamine. In combination with the filter compounds typically used in heavy-duty detergents, and especially in combination with the perphosphate salts typically used, the bleaching activators described above can be
[The ability to remove product stains is improved. Preferred textile pre-treatment formulations of the invention to improve their effectiveness include both non-ionic surfactants, cationic surfactants and white activators of the type described above. A particularly effective and therefore preferred formulation has a viscosity of at least 500,000 min Fm, preferably at least 61,000,000 min.
4,000,000, more preferably a thickener combination of a polyacrylic acid derivative and a fatty acid derivative, preferably a fatty acid ester, and a diluent mixture of propylene glycol, glycerol and ethanol.

In a typical embodiment of the method of the invention, CI4~C+s

The remaining propylene glycol, cocosamine ethoxylate and ethylene glycol stearate were added to a stirred vessel equipped with a horseshoe stirrer and a Teflon wall stripper. The mixture was cooled with continuous stirring and after the temperature was below 40°C, ethanol and tetraacedelethylenediamine were added. Finally, the mixture was cooled to room temperature.
