Abstract
Personal cleansing compositions containing surfactant and selected cationic polymer provide products having improved odor stability. This "bulky amine" cationic polymer is: Guar (POLYMER)-CR.sup.1 HCR.sup.2 R.sup.3 --CH.sub.2 NR.sup.4 R.sup.5 R.sup.6 wherein R.sup.1 -R.sup.3 is a --H or --OH substituent, and wherein at least one of R.sup.4, R.sup.5 and R.sup.6 are selected from the group consisting of alkyl having a chain length of from about 2 to about 24 carbon atoms, and alkoxy alkyl containing from about 2 to about 12 carbon atoms, and mixtures thereof. The cationic polymer is less odoriferous than trimethylamine-based cationic polymers. The personal cleansing composition ash a pH of at least 7.5 in a 1% aqueous solution.
