| titleOfInvention | Water-dispersible polyurethane, its application and cosmetic preparation |
| abstract | FIELD: chemistry. n SUBSTANCE: invention relates to water-dispersible polyurethane, method of obtaining thereof, thereof application and cosmetic preparation, containing polyurethane as thickening agent. Water-dispersible polyurethane contains mainly linear basic chains, consisting of alternating hydrophilic and hydrophobic sections. Polyurethane has two terminal sections (T), which are hydrophobic, and, at least, one hydrophobic terminal section (T) represents branched alkyl residue. Hydrophilic section (S) is directly attached to each section (T). At least, one hydrophobic section (D) is directly attached to, at least, one end of each of sections (S). The main polyurethane chain contains, at least, one hydrophilic section (P), and if there is more than one section (P), two sections (P) are separated with, at least, one hydrophobic section (D). Polyurethane contains, at least, three hydrophilic sections. Ratio of molecular weight of any of hydrophilic sections (S) to molecular weight of any of hydrophilic sections (P) lies within the interval from 1:1.4 to 1:70. At least, two hydrophobic sections (D) are aliphatic diisocyanate residues, and, at least, one hydrophilic section (P) represents residue of polyether with number average molecular weight, at least, 1500 g/mol. Polyurethane can represent mixture of different mentioned above polyurethanes. Polyurethanes are obtained in two steps. At the first stage interaction of, at least, one polyether diol with, at least, one aliphatic diisocyanate is realised in presence of zinc carboxylate in solvent medium. At the second stage obtained product is subjected to interaction with, at least, one ethoxylated aliphatic alcohol in solvent medium. After that, separation of solvents is performed and water is added. Polyurethanes are applied for manufacturing of water-containing cosmetic preparation. n EFFECT: invention makes it possible to increase viscosity of cosmetic preparations and their storage stability. n 10 cl, 4 tbl, 11 ex |
