The present invention relates to a process for depleting epoxide species in epoxy-crosslinked polysaccharide gel compositions. In addition, the present invention relates to crosslinked polysaccharide gel compositions made by said process and their use in cosmetic and therapeutic applications.

Process for depleting epoxide species in crosslinked polysaccharide gel compositions and compositions obtained thereby

The present invention relates to a sterile in situ cross-linkable polysaccharide compositions for augmenting, filling or replacing soft tissues in various cosmetic and therapeutic applications. The composition comprises a first polysaccharide derivative functionalized with a nucleophilic group and a second polysaccharide derivative functionalized with an electrophilic group. Said nucleophilic and electrophilic functional groups spontaneously form in situ covalent linkages following co-injection in the body of a patient, resulting in the formation of a cross-linked hydrogel at the site of co-injection.

In situ cross-linkable polysaccharide compositions and uses thereof

The present invention generally relates to a modified hyaluronic acid (HA) and to a method for making same, more specifically to a (poly)glycerol-modified HA derivative prepared by grafting glycidol to HA. The present invention also relates to the use of the HA derivative for preparing a dermal filler composition, a hydrogel comprising cross-linked HA and the (poly)glycerol-modified HA derivative, and a method for preparing said hydrogel. Furthermore, the present invention relates to the use of the hydrogel as a cosmetic and/or aesthetic product, in particular as a dermal filler for tissue filling, replacing and/or augmenting.

Modified hyaluronic acid, method for making same and uses thereof

The present invention relates to a composition for the in vivo degradation of polysaccharide-containing fillers by radical degradation. The composition of the invention comprising at least one source of oxygen free radicals and at least one catalyst of oxygen free radical generation from the at least one source of oxygen free radicals. The present invention further relates to methods and uses of said composition for filler correction or reversal.

In vivo accelerated degradation of polysaccharide-containing fillers

The present invention relates to polysaccharide soft tissue fillers comprising heparosan and processes for their preparation. The polysaccharide soft tissue fillers of the present invention are advantageously used in therapeutic or cosmetic applications such as for the filling of wrinkles.

Polysaccharide soft tissue fillers with improved persistence

The present invention relates to a process for the production of wood-base materials which have at least one thin veneer layer adhesively bonded over the surface to a substrate or to further veneer layers, which process comprises the following steps:

Method for producing wood-base materials

The invention relates to a lignocellulose material comprising a crosslinkable nitrogen compound, technically a formaldehyde condensate, in crosslinked form in a constituent amount (N) of at least 1% by weight, calculated as nitrogen and based on the total weight of the lignocellulose material, in which the ratio (FA/N) of formaldehyde emission (FA), determined by means of the bottle method according to EN 717, part 3, to constituent amount of the nitrogen compound (N) exhibits a value of at most 5.0&#xd7;10, and to a process for the preparation thereof.

Lignocelluosic material which is low in formaldehyde and method for the production thereof

The invention relates to a method for the treatment of surfaces of wood or woodbase materials with surface treatment compositions, and the timbers or woodbase materials thus treated by impregnating with a curable aqueous composition of &#x3b1;) low molecular weight compounds V which have at least two N-bonded groups and/or &#x3b2;) precondensates of the compound V and/or &#x3b3;) reaction products or mixtures of the compound V with at least one alcohol which is C-C-alkanols, C-C-polyols or oligoalkylene glycols; treating that impregnated material at elevated temperature and) treating at least one surface of the wood or woodbase material to be treated with a surface treatment composition.

Method for treating wood surfaces
