Definitions
- the present invention relates to the use of esters of polyisobutene succinic acid for the preparation of hydrogels and to the use of such hydrogels for household cleaners and care products (so-called homecare products), for cosmetics and for medical products.
- biomaterials in the pharmaceutical or medical field, for example for contact lenses, wound closure materials, soft implants, for coating surfaces, for example biomedical objects such as implants or contact lenses, for the production of biosensors (see Römpp Chemie Lexicon, 10th edition, Georg Thieme Verlag 1997, p. 1835 and literature cited therein).
- hydrogels loaded with perfume or surfactants are used in fragrance dispensers or as cleansers.
- EP 1318191 discloses water-containing pastes for dispensing fragrances for the sanitary sector, which in addition to water and perfume substances contain a block copolymer which comprises oligo- or polyethylene oxide, oligo- or polypropylene oxide, or oligo- or polybutylene oxide groups. Specifically, polyoxyethylene-polyoxypropylene di- and triblock copolymers are named.
- Such pastes adhere well to ceramic surfaces and are not rinsed as a whole under the action of water, but slowly and completely dissolve only after or with frequent repeated exposure to water.
- a disadvantage proves that such pastes tend to dehydrate at less frequent exposure to water or at longer intervals between repeated actions of water and then can no longer be completely removed. Also, these dried out pastes look unattractive.
- Another disadvantage of these pastes is their low dimensional stability, causing them to run down the Keramikwandung and form unsightly "noses”.
- the present invention has for its object to provide new gelling agents for hydrogels. These gelling agents should form hydrogels that have at least one are dimensionally stable over a longer period of time and also have no or no significant surfactant properties. In addition, biocompatibility is desirable.
- WO 02/02674 describes block copolymers, in particular triblock copolymers and higher multiblock copolymers, which are obtainable by reacting silane-terminated polyisobutene with allyl-terminated polyalkylene glycol ethers.
- the block copolymers are swellable with water. Their production is comparatively complicated.

- the invention thus relates to the use of esters of polyisobutene succinic acid with an alcohol selected from poly-C 2 -C 4 -alkylene glycols and poly-C 2 -C 4 -alkylene glycol mono-C 1 -C 22 -alkyl ethers in hydrogels or as gelling agents for hydrogels, in particular in hydrogels in household cleaning and care products (homecare products), cosmetics and medical products.
- the invention also relates to hydrogels, in particular hydrogels for cleaning and care products for the household, for cosmetics and for medical products, wherein the hydrogels in addition to water at least one ester of polyisobutenesuccinic acid with one of poly-C2-C4-alkylene glycols and poly-C2-C4 alkylene glycol mono-C 1 -C 22 alkyl ethers containing selected alcohol.
- the invention also relates to the use of such esters for the preparation of hydrogels and to a process for preparing the hydrogels comprising reacting at least one ester of polyisobutene succinic acid with one of poly-C 2 -C 4 -alkylene glycols and poly-C 2 -C 4 -alkylene glycol mono -Ci-C22-alkyl ethers incorporated alcohol in an aqueous liquid, or mixed with the aqueous liquid.
- the hydrogels of the invention are stable, d. H. they are dimensionally stable over a wide temperature range of for example 0 to 90 ° C, in particular 0 to 70 ° C and are not prone to segregation even under mechanical stress.
- the gel formers contained therein, d. H. the esters of polyisobutene succinic acid described here also show no surfactant properties, ie. H. at a concentration of 1 g / l they do not lower the surface tension of the water below 45 mN / m, determined by the ring method according to DIN 53914: 1980-03 at 25 ° C. Due to the gel formers used, the hydrogels are also biocompatible, i. H. they have no or no appreciable adverse effect on living or living material such as cell material or tissue.
- the hydrogels according to the invention have a good adhesion to polar surfaces, in particular inorganic surfaces such as glass or ceramic, and are not rinsed off immediately upon exposure to water, but rather dissolve without leaving any residue after prolonged and frequently repeated exposure to water. They can also be formulated with fragrances or other substances that promote the cleaning or disinfection of sanitary ceramics, without disadvantages. Furthermore, these hydrogels tend to dry only to a small extent. In addition, the hydrogels are dimensionally stable and are therefore suitable for the production of moldings, for. B. in fragrance dispensers.
- the hydrogels according to the invention can be formulated in a simple manner with perfumes or other additives for cleaning agents, such as, for example, surfactants, dyes, preservatives, disinfectants, complexing agents, thickeners, humectants, disintegrants, foam stabilizers or lime or urine stone-dissolving substances, and are particularly suitable for the use in the sanitary area. They adhere well to ceramic surfaces and are not rinsed off as a whole under the action of water, but dissolve slowly and completely only after frequently repeated exposure to water.
