    摘要: Compounds of the formulae:
    are useful as humectants e.g. in cosmetic compositions. In the formulae, n is 1 or 2, q and p are positive integers and the product of q and p is equal to n; R¹ is a saturated or unsaturated hydrocarbyl radical and when n is 1, R¹ can be hydrogen, and when n is 2, R¹ can be a single bond; R² is a substituted or unsubstituted alkylene group; R³, R⁴ and R⁵ are substituted and unsubstituted alkyl groups; and R⁶ is ethylene, substituted ethylene, or an ortho-aromatic structure. The compounds are prepared by reacting a carboxylic acid or derivative thereof with an N, N-­disubstituted alkyldiamine in order to form a corresponding amide, and then quaternizing the amide with an alkylating agent.
