    • The present invention relates to hydrogel adhesives which are capable of attaching to mammalian skin, exhibit excellent attachment and painless removal properties, and which show excellent stability upon storage at room temperature or even at elevated temperatures and for longer periods of time. The adhesive hydrogel described in the present invention can be used as body adhesive in products for e.g. personal care, medical devices, beauty care and a variety of functional articles to be worn by a human. The hydrogel adhesive of the invention comprises 10-60 wt.% of a cross-linked hydrophilic polymer, 5-80 wt.% of a water-soluble non-ionic humectant, and from about 10-85 wt.% water, wherein the hydrophilic polymer comprises at least 80 mole % of one or more weak-acid monomer units having a pKa above 3, the weak-acid monomer being more than 60 mole % in its salt form, the level of monomer in acid form in said hydrophilic polymer not exceeding 50 mole % of all monomer units and the hydrogel adhesive having a peel strength on PET of 0.3 to 5.0 N/cm and a stability index measured after 14 days SIx14 below 0.50, preferably below 0.20, most preferably below 0.10.

    • The invention relates to aqueous dispersions of water-soluble and/or water-swellable anionic polymers, which can be obtained by the radical polymerisation of ethylenically unsaturated anionic monomers in an aqueous medium in the presence of at least one stabiliser. According to the invention, the polymerisation is carried out in the presence of at least one water-soluble polymer, acting as a stabiliser, from the following groups: (a) polymers of vinyl acetate and/or vinyl propionate grafted onto (i) polyethylene glycols or (ii) polyethylene glycols or polypropylene glycols, whose end groups are terminated on one or both sides with alkyl, carboxyl or amino groups, polyalkylene glycols, or polyalkylene glycols, whose end groups are terminated on one or both sides with alkyl, carboxyl or amino groups and (b) water-soluble copolymers consisting of (b1) non-ionic monoethylenically unsaturated monomers, (b2) cationic monoethylenically unsaturated monomers and optionally (b3) anionic monoethylenically unsaturated monomers, the fraction of the polymerised cationic monomers being greater than that of the anionic monomers. The invention also relates to a method for producing the aqueous dispersions by the radical polymerisation of the anionic monomers in an aqueous medium in the presence of the aforementioned water-soluble polymers (a) and (b), in addition to the use of the aqueous dispersions as thickening agents for aqueous systems.
