A water-soluble and/or water-swellable hybrid polymer comprising: wherein components (i) and (ii) are polymerized by radical precipitation polymerization in a polar solvent.

Water-soluble and/or water-swellable hybrid polymer

A water-soluble and/or water-swellable hybrid polymer comprising: 

The present invention relates to a polymer comprising: (a) from 90 mol-% to 99.9 mol-%, of repeating units according to Formula (1) wherein at least 10 wt.-% of the repeating units according to Formula (1) comprise from 28 wt.-% to 100 wt.-% bio-based carbon content, relative to the total mass of carbon in the repeating unit according to Formula (1), measured according to standard ASTM D6866-12, Method B; and (b) from 0.01 mol-% to 10 mol-% of crosslinking or branching units, wherein the crosslinking or branching units result from the incorporation of a monomer comprising at least two olefinically unsaturated double bonds.

Polymer comprising certain level of bio-based carbon

The present invention relates to the use of a polymer in a cosmetic, dermatological or pharmaceutical composition, wherein the polymer is crosslinked or non-crosslinked, characterized in that the polymer comprises at least 9.49 mol-% of repeating units (a) according to Formula (1) wherein at least 10 wt.-%, preferably at least 20 wt.-% of the repeating units according to Formula (1) comprise from 28 wt.-% to 100 wt.-% bio-based carbon content, relative to the total mass of carbon in the repeating unit according to Formula (1), measured according to standard ASTM D6866-12, Method B 

Use of a bio-based polymer in a cosmetic, dermatological or pharmaceutical composition

The present invention relates to a compound according to Formula (3), wherein the compound comprises from 28 wt. % to 100 wt. % bio-based carbon content, relative to the total mass of carbon in the compound, measured according to standard ASTM D6866-12, Method B;  and wherein Xis a proton. The present invention also relates to a polymer obtained by polymerising at least one of compound according to Formula (3), in addition to processes and uses related thereto.
