摘要 PCT No. PCT/GB93/00965 Sec. 371 Date Feb. 17, 1995 Sec. 102(e) Date Feb. 17, 1995 PCT Filed May 10, 1993 PCT Pub. No. WO93/23457 PCT Pub. Date Nov. 25, 1993Carbomer or cross-polyacrylate polymers which are conventionally provided in a powdered form are converted to a granulated, pelletized or tablet form for subsequent use, in combination with a liquid medium, to form a gel from which products such as liquid detergents, cosmetics and toiletries can be produced. Conversion of the polymer into a granular, pelletized or tablet form has been demonstrated to improve handling of the dry polymer, thereby mitigating against many of the problems incurred with the use of conventional powders, as well as to improve the rate of blending of the polymer with a liquid medium. In some embodiments, the polymer is blended with an electrolyte which may be a salt, acid or acid salt having a pK which is at least 1 unit, and preferably 2 units, greater than the pK of the polymer.
