Definitions
- the present invention relates to the use of polyisobutene and polyisobutene derivatives as a substitute for raw and / or purified, optionally chemically modified wool fat and wool fat mixtures in fatliquoring agents for leather production, preparations, in particular fatliquoring agents, containing polyisobutene and their use in leather production, and a method for the production of these preparations and the leathers produced using these preparations.
- fatliquoring agents serve to make skins and pre-tanned leather supple, to increase their fullness and strength and to protect them from moisture, dirt and chemical influences from outside (see H. Herfeld, "Library of Leather", Vol. 4 , (1985), p. 13 ff., P. 59 ff. Frankfurt am Main: Umschau Verlag 1987)). They should cover the individual skin fibers with a thin film of fat to isolate them from each other and keep them movable, but on the other hand they should not completely fill the spaces between the fibers, otherwise the porosity and the breathability of the leather will be impaired.
- greasing agents generally consist of greasing substances, such as native fats, fatty oils, waxes, resins and their derivatives and / or petroleum fractions and their derivatives, and waxy products such as "wool fat", in raw, cleaned and / or prepared (lanolin)
- the fatty substances can, if desired, be chemically modified, ie they can be in a modified chemical structure.
- the aim of these chemical modifications is to optimally adapt the application-related properties of the greasing substances, such as, for example, hydrophilicity, hydrophobicity, solubility, dispersibility, penetration and anchoring properties, special uses or the requirements of the users.
- wool fat In its raw and / or chemically modified form, but especially in its cleaned or prepared forms (lanolin), wool fat is of great importance in the field of leather production. There wool fat, in particular lanolin, is used as neutral fat. A certain hydrophobic effect is added to the greasing and filling effect.
- Wool fat in terms of its composition more appropriately referred to as wool wax, is a fat-like secretion from the sebum glands of sheep, which is found in their
- Wool settles and is obtained from it through complex and therefore expensive cleaning processes.
- Raw wool fat lanolin
- lanolin is a greasy, foul-smelling, yellow-brown
- a total of over 30 different fatty acids and aliphatic triterpenoid and steroid alcohols have been identified in wool fat.
- the malodorous and coloring components of the raw wool fat are largely destroyed by oxidation.
- the pure water-free wool fat (wool wax) obtained in this way is a light yellow, translucent mass, with a weak, pleasant smell with a density
- lanolin is a mixture which is made by melting together about 65 parts of wool fat, about 20 parts of water and about 15 Parts of viscous paraffin.
- neutral wool wax or "lanolin”
- purified and highly purified wool grease is used in cosmetics in creams, in toilet soaps it serves as a superfatting agent, in pharmacy it is used e.g. used in the manufacture of plasters, ointments and suppositories and in tablet pressing it can serve as a release agent.
- High quality lanolin as used in the cosmetic and medical industry, has a market price of approx. 8-10 DM / kg. Less pure, "inferior” lanolin is incorporated into fatliquors as a neutral fatlip component.
- lanolin has a number of disadvantages. Since lanolin is native, you always have to expect fluctuating composition, purity, and quality, as well as seasonal price fluctuations. For the manufacturers of lanolin-containing products, this means permanent optimization and revision of the setting of their products in order to be able to manufacture products with consistent quality. Last but not least, due to the increasing demand for high-quality lanolin, the available quantities of inferior lanolin decrease, which has led to an extreme price increase of the latter (from approx. 2 DM / kg to 6-8 DM / kg).
- An object of the present invention was to provide a synthetic compound
- An object of this invention are thus fatliquors for the fatliquoring of skins and for the production of leather, comprising neutral and / or optionally chemically modified native fatliquoring components, and one or more emulsifiers, which are characterized in that the lipidifying components are polyisobutene and / or

- R has one of the meanings given for R, with the exception of hydrogen, where the two R 3 radicals can be the same or different,
- R 4 and R 5 may be the same or different and represent hydrogen, hydroxy, lower alkoxy, poly-lower alkoxy or one of the radicals R 4 or R 5 represents hydrogen and the other represents a sulfato group (- OSO 3 H), a sulfone group (-SO 3 H), an amino, alkylamino or dialkylamino group with a total of 1 to 6, preferably 2 to 4, C atoms in the alkylamino or dialkylamino groups, or for groups of the formula -O (C p H 2p ) COOH, where p is an integer from 1 to 7, preferably 1 to 3, or their salts or their lower alkyl esters having 1 to 5, preferably 1 to 3, C atoms in the lower alkyl radical.
- compounds of the formula I can be used individually or in a mixture with one another. This enables an excellent adaptation of the substitute materials to specific tasks.
- Polyisobutene corresponds to the formula I in which R is a radical of the formula II, where R is hydrogen.
- Poly-lower alkoxy groups correspond to the formula -O (C m H 2m O) x H, where m is an integer from 2 to 4 and x is a number from 1 to 200, preferably from 3 to 80, and m in the individual components of the Polyether chain can be different.
- Lower acyloxy groups have a total of 2 to 5, preferably 2 or 3, carbon atoms. Examples of lower acyloxy groups are the acetyloxy, the propionyloxy and the butyryloxy group.
- alkyl radicals representing R 2 and / or R 3 are carboxyl or carboxylate groups or functional derivatives thereof, such as, for. B. nitriles, amides and especially esters or anhydrides, with alkyl (1) and alkyl (2) radicals are particularly preferred in which the said substituents are bonded to the alkyl radical in the 1- or 2-position are.
- substituted alkyl groups which can represent R 2 or R 3 are:
- Polyisobutene itself is produced on a large industrial scale in various types, which differ in their molecular weight, and is marketed under various names, for example as ® Oppanole and ® Glissopale. They are usually produced by polymerizing isobutene in the presence of Friedel-Crafts catalysts such as boron trifluoride or aluminum chloride.
- Polyisobutene derivatives of the formula I which contain carboxyl groups or their functional derivatives in radicals R 2 and / or R 3 are expediently prepared from polyisobutene by an ene reaction, ie by reaction of polyisobutene of the desired molecular weight or of compounds of the formula I in which R 1 is a radical of formula II with enophiles containing the desired substituents.
- Enophiles suitable for this implementation include: Acrylic acid, methacrylic acid, vinyl acetic acid, crotonic acid, angelica or tiglinic acid, cinnamic acid, maleic acid, citraconic acid or their esters with alkanols with 1 to 6, preferably 1 to 3 C atoms or with alkylamino or dialkylaminoalkanols with 2 to 4 C atoms in the alkylamino or dialkylamino groups, their amides or their nitriles, maleic anhydride and citraconic anhydride.
- the conditions of the ene reaction are known. If less reactive enophiles are used, the reaction can, if desired, be carried out in a known manner by adding Friedel-Crafts catalysts, e.g. Boron trifluoride or aluminum chloride, can be significantly accelerated.
- Friedel-Crafts catalysts e.g. Boron trifluoride or aluminum chloride
- Neutral fatliquoring components are substances of fat-like character with longer or long alkyl residues that do not have any anionic or cationic groups, such as white oil, paraffins, native oils, silicones or wool wax.
- a substance that is frequently used as a neutral lipid component is "lanolin".
- the raw or cleaned and / or chemically modified wool fat (wool wax) or lanolin contained in leather greasing agents can be either completely or partially be replaced by polyisobutene and / or the polyisobutene derivatives to be used according to the invention as a substitute. It is therefore possible that the fatliquoring agent according to the invention containing polyisobutene or polyisobutene derivatives also contains the said, optionally chemically modified wool fat or lanolin as the fatliquoring component.
- Possibly chemically modified native fatty components have an aliphatic residue of medium or long chain length and one or more hydrophilic groups, preferably of an anionic character.
- Components of this type that do not require any chemical modification are, for example, medium and long chain carboxylic acids, such as oleic acid.
- sulfated or partially sulfated long-chain aliphatic compounds containing one or more olefinic double bonds can be used as chemically modified native fat components.
- fat substances of vegetable or animal origin, in particular glycerides of natural fatty acids with a sufficient proportion of unsaturated acids serve as native fat components.
- Well-suited fatty substances are vegetable and animal fats and oils with an iodine number of approx. 10 to approx. 200.
- fatty substances depends, among other things, on the special purpose for which the mixture according to the invention is to be used. For example, prohibit the use of fish oils in the manufacture of fine leather goods because of the smell of these fats. Fatty substances with iodine numbers from approximately 30 to approximately 120, in particular from 40 to 85, are preferred.
- particularly preferred fatty substances are sebum types of various origins, bone oil, nitro oil, claw oil, lard oil, triolein, rapeseed oil, olive oil, nut oil and castor oil.
