Abstract
The present invention provides quaternary ammonium-substituted saponin ethers having improved electrostatic and hydrophobic interactive activities, and therefore very useful in hair-care and skin-care products. The product of the invention, particularly, eliminates efficiently the static flyaway of hair and gives excellent conditioning effect to hair when used in hair-care products. The quaternary ammonium-substituted saponin ethers can be prepared by reacting a soya or ginseng saponin or an aglycone thereof with a cationic compound selected from quaternary ammonium halohydrin or quaternary ammonium epoxide.
