Hydrophobic carbomer complex compositions |
摘要 |
Hydrophilic carbomer complexes, such as bismuth or nicotine carbomer, are rendered hydrophobic at neutral to acid pH by milling to pass a 150 mu m sieve screen and then impregnating with a water-insoluble anionic polymer. Preferred anionic polymers are partly methyl esterified methacrylic acid polymers. |
