摘要:
Cosmetic compositions useful for treatment of hair or skin contain macromolecular glyceryl-chitosan having(a) 4-40 Mol-% units of the Formula (I) ##STR1## and (b) 60-96 Mol-% units of the Formula (II) ##STR2## wherein R.sub.1, R.sub.2 and R.sub.3 are the same or different and are ##STR3## wherein R.sub.4 and R.sub.5 are the same or different and are ##STR4## wherein either X=H and Y=CH.sub.2 OH, or Y=H and X=CH.sub.2 OH and n=2 to 5, with the proviso that for at least half of the units of the formula II, R.sub.1, R.sub.2 and R.sub.3 are not uniformly H, or their salts with organic or inorganic acids, in a suitable cosmetic carrier. Also disclosed are the compounds per se and a process for their production wherein chitosan composed of 60-96% entacetylated chitin is reacted with glycidol.
摘要:
The quaternary chitosan derivatives useful in cosmetic compositions are made by a process comprising reacting a chitosan consisting of 50 to 100% deacetylized chitin or a structurally modified chitosan made by reprecipitating and deep freezing, with glycidyl trialkyl ammonium halogenide, particularly glycidyl trimethyl ammonium chloride, and, if necessary, with glycidol. The reaction mixture is advantageously stirred for several hours at 10.degree. to 100.degree. C. The reaction may be performed in the presence of an organic or inorganic acid or base in water.

摘要:
The aqueous hair fixing gel has special rheological properties so that it can be dispensed from a container without dripping or becoming stringy. It contains from 1.5 to 10 percent by weight of at least one itaconic acid monoester/acrylate copolymer and from 0.1 to 15 percent by weight of at least one non-ionic, anionic, zwitterionic or amphoteric hair-fixing polymer. The itaconic acid monoester has a formula CH2═C(COOR1)CH2COOR2, wherein one of R1 and R2 represents hydrogen and the other represents —(CH2CH2O)x—R3, x is between 1 to 100 and R3 is an alkyl group having 8 to 30 carbon atoms. The aqueous hair treatment gel has a pH of greater than 7 and a viscosity of preferably from 2000 to 50,000 mPa.s, as measured at 25° C. The gel is formulated so that there is a gel viscosity maximum as a function of shear rate with increasing shear rate, preferably between 0.1 to 5.0 s−1.
