Abstract: The present invention relates to polymerized hydrogels and processes to make such hydrogels, in particular hydrogel adhesives which are capable of attaching to mammalian skin and can be used in various personal care product s, such as waste-management articles, and a variety of functional articles to b e worn by a human. The hydrogels described herein are characterized by very lo w amount of residual starting monomers, impurities, and/or by-products that could be formed during polymerization. Specifically, the hydrogels are made by adding scavengers and/or chain transfer agent prior to polymerization.It has been found, that upon addition of same scavengers the material properties of the polymerized hydrogel differ from the properties of gels polymerized without the scavenger. This is due to the fact, that these specific scavenge rs act also as chain transfer agents in the radical polymerization.Further studies showed that also chain transfer agents, that are no scanvengers for residual monomer(s), impurities or byproducts influence the material properties of the polymerized hydrogel adhesive.

Abstract: The present invention relates to hydrogel adhesives for attachment to mammalian skin which exhibit particularly good compatibility with skin, in addition to excellent attachment and painless removal properties including in excess moisture conditions. Such adhesives comprise 10-60 wt% of a cross- linked hydrophilic polymer, 5-80 wt% of a water-soluble nonionic humectant, and 10-85 wt% water. The hydrophilic polymer comprises 1-50 mole% of one or more strong-acid monomers having a pKa below 3 and 50-99 mole% of one or more weak-acid monomers, having a pKa above 3, the strong-acid monomer being essentially in its salt form, and the weak-acid monomer being at least 50 mole% in its acid form, and at least 5 mole% in its salt form. The pH of the hydrogel adhesive is from 3 to 6, preferably from 3 to 5.5, most preferably 3.5 to 5. The present invention also encompasses personal care products containing said adhesives, such as disposable waste management articles, disposable absorbent articles, and various functional articles for attachment to the human body.

Abstract: The present invention relates to polymerized hydrogel adhesives, in particular those wherein the hydrogel is formed from monomers which include acrylamido-2- methane propanesulfonic acid or salts thereof (AMPS monomers) and those which contain glycerol as a humectant. In such adhesives, the levels of unpolymerized residual monomers, such as unpolymerized AMPS, acrylonitrile, acrylamide and t-butyl acrylamide; and the levels of other impurities such as acrolein, are kept very low. The present invention also relates to a process for making hydogel adhesives with very low levels of such unwanted materials. Such a process involves preparation of reaction mixtures under selected pH and/or temperature conditions and polymerization of AMPS monomers using selected conditions of pH and UV curing.

Abstract: Hydrophilic open-celled resilient foams containing melamine-formaldehyde resins, characterized by a droplet absorption rate of less than 5 seconds and an EU standard EN ISO 14184-1 formaldehyde emission of less than 100 mg of formaldehyde/kg of foam, and obtainable by(a) heating an aqueous solution or dispersion each containing at least a melamine-formaldehyde precondensate, an emulsifier, a blowing agent and a curing agent to form a foam and crosslink the precondensate,(b) then conditioning the foam at from 120 to 300° C. for from 1 to 180 minutes to remove volatiles, and(c) treating the foam during the conditioning or thereafter with at least one hydrophilicizer and/or with ozone, a corona discharge or a plasma,are useful in hygiene articles to acquire, distribute and immobilize body fluids.
